+# Spanish Checkers #
+
+This is a project of an online game of the spanish variant of checkers or draughts. I've made this project as part of a university project as a proof of concept for me to learn NodeJS and Socket.io. It uses the following NodeJS libraries: Socket.io, Express, Body-parser.
+
+It is by no means the best implementation of checkers, and it may lack some features, but it pretty much playable and the only thing that is required to play it is a relatively modern web browser with Html5 and javascript support, and of course, a friend to play with.
+
+The game can be played online at [checkers.yaroslavps.com](http://checkers.yaroslavps.com).

+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator).
+Extracted from [koa](https://www.npmjs.com/package/koa) for general use.

+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])`
+  as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install accepts
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app (req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch (accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+# After [![Build Status][1]][2]
+
+Invoke callback after n calls
+
+## Status: production ready
+
+## Example
+
+```js
+var after = require("after")
+var db = require("./db") // some db.
+
+var updateUser = function (req, res) {
+  // use after to run two tasks in parallel,
+  // namely get request body and get session
+  // then run updateUser with the results
+  var next = after(2, updateUser)
+  var results = {}
+  
+  getJSONBody(req, res, function (err, body) {
+    if (err) return next(err)
+    
+    results.body = body
+    next(null, results)
+  })
+  
+  getSessionUser(req, res, function (err, user) {
+    if (err) return next(err)
+    
+    results.user = user
+    next(null, results)
+  })
+  
+  // now do the thing!
+  function updateUser(err, result) {
+    if (err) {
+      res.statusCode = 500
+      return res.end("Unexpected Error")
+    }
+    
+    if (!result.user || result.user.role !== "admin") {
+      res.statusCode = 403
+      return res.end("Permission Denied")
+    }
+    
+    db.put("users:" + req.params.userId, result.body, function (err) {
+      if (err) {
+        res.statusCode = 500
+        return res.end("Unexpected Error")
+      }
+      
+      res.statusCode = 200
+      res.end("Ok")  
+    })   
+  }
+}
+```
+
+## Naive Example
+
+```js
+var after = require("after")
+    , next = after(3, logItWorks)
+
+next()
+next()
+next() // it works
+
+function logItWorks() {
+    console.log("it works!")
+}
+```
+
+## Example with error handling
+
+```js
+var after = require("after")
+    , next = after(3, logError)
+
+next()
+next(new Error("oops")) // logs oops
+next() // does nothing
+
+// This callback is only called once.
+// If there is an error the callback gets called immediately
+// this avoids the situation where errors get lost.
+function logError(err) {
+    console.log(err)
+}
+```

+# backo
+
+  Simple exponential backoff because the others seem to have weird abstractions.
+
+## Installation
+
+```
+$ npm install backo
+```
+
+## Options
+
+ - `min` initial timeout in milliseconds [100]
+ - `max` max timeout [10000]
+ - `jitter` [0]
+ - `factor` [2]
+
+## Example
+
+```js
+var Backoff = require('backo');
+var backoff = new Backoff({ min: 100, max: 20000 });
+
+setTimeout(function(){
+  something.reconnect();
+}, backoff.duration());
+
+// later when something works
+backoff.reset()
+```

+base64id
+========
+
+Node.js module that generates a base64 id.
+
+Uses crypto.randomBytes when available, falls back to unsafe methods for node.js <= 0.4.
+
+To increase performance, random bytes are buffered to minimize the number of synchronous calls to crypto.randomBytes.
+
+## Installation
+
+   $ npm install base64id
+
+## Usage
+
+   var base64id = require('base64id');
+
+   var id = base64id.generateId();

+# better-assert
+
+  Better c-style assertions using [callsite](https://github.com/visionmedia/callsite) for
+  self-documenting failure messages.
+
+## Installation
+
+    $ npm install better-assert
+
+## Example
+
+ By default assertions are enabled, however the __NO_ASSERT__ environment variable 
+ will deactivate them when truthy.
+
+```js
+var assert = require('better-assert');
+
+test();
+
+function test() {
+  var user = { name: 'tobi' };
+  assert('tobi' == user.name);
+  assert('number' == typeof user.age);
+}
+
+AssertionError: 'number' == typeof user.age

+Blob
+====
+
+A module that exports a constructor that uses window.Blob when available, and a BlobBuilder with any vendor prefix in other cases. If neither is available, it exports undefined.
+
+Usage:
+
+```javascript
+var Blob = require('blob');
+var b = new Blob(['hi', 'constructing', 'a', 'blob']);
+```

+Node.js body parsing middleware.
+
+Parse incoming request bodies in a middleware before your handlers, available
+under the `req.body` property.
+
+[Learn about the anatomy of an HTTP transaction in Node.js](https://nodejs.org/en/docs/guides/anatomy-of-an-http-transaction/).
+
+_This does not handle multipart bodies_, due to their complex and typically
+large nature. For multipart bodies, you may be interested in the following
+modules:
+
+  * [busboy](https://www.npmjs.org/package/busboy#readme) and
+    [connect-busboy](https://www.npmjs.org/package/connect-busboy#readme)
+  * [multiparty](https://www.npmjs.org/package/multiparty#readme) and
+    [connect-multiparty](https://www.npmjs.org/package/connect-multiparty#readme)
+  * [formidable](https://www.npmjs.org/package/formidable#readme)
+  * [multer](https://www.npmjs.org/package/multer#readme)
+
+This module provides the following parsers:
+
+  * [JSON body parser](#bodyparserjsonoptions)
+  * [Raw body parser](#bodyparserrawoptions)
+  * [Text body parser](#bodyparsertextoptions)
+  * [URL-encoded form body parser](#bodyparserurlencodedoptions)
+
+Other body parsers you might be interested in:
+
+- [body](https://www.npmjs.org/package/body#readme)
+- [co-body](https://www.npmjs.org/package/co-body#readme)
+
+## Installation
+
+```sh
+$ npm install body-parser
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var bodyParser = require('body-parser')
+```
+
+The `bodyParser` object exposes various factories to create middlewares. All
+middlewares will populate the `req.body` property with the parsed body when
+the `Content-Type` request header matches the `type` option, or an empty
+object (`{}`) if there was no body to parse, the `Content-Type` was not matched,
+or an error occurred.
+
+The various errors returned by this module are described in the
+[errors section](#errors).
+
+### bodyParser.json([options])
+
+Returns middleware that only parses `json` and only looks at requests where
+the `Content-Type` header matches the `type` option. This parser accepts any
+Unicode encoding of the body and supports automatic inflation of `gzip` and
+`deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`).
+
+#### Options
+
+The `json` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### reviver
+
+The `reviver` option is passed directly to `JSON.parse` as the second
+argument. You can find more information on this argument
+[in the MDN documentation about JSON.parse](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/JSON/parse#Example.3A_Using_the_reviver_parameter).
+
+##### strict
+
+When set to `true`, will only accept arrays and objects; when `false` will
+accept anything `JSON.parse` accepts. Defaults to `true`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `json`), a mime type (like
+`application/json`), or a mime type with a wildcard (like `*/*` or `*/json`).
+If a function, the `type` option is called as `fn(req)` and the request is
+parsed if it returns a truthy value. Defaults to `application/json`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.raw([options])
+
+Returns middleware that parses all bodies as a `Buffer` and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a `Buffer` object
+of the body.
+
+#### Options
+
+The `raw` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `bin`), a mime type (like
+`application/octet-stream`), or a mime type with a wildcard (like `*/*` or
+`application/*`). If a function, the `type` option is called as `fn(req)`
+and the request is parsed if it returns a truthy value. Defaults to
+`application/octet-stream`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.text([options])
+
+Returns middleware that parses all bodies as a string and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser supports automatic inflation of `gzip` and `deflate` encodings.
+
+A new `body` string containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This will be a string of the
+body.
+
+#### Options
+
+The `text` function takes an optional `options` object that may contain any of
+the following keys:
+
+##### defaultCharset
+
+Specify the default character set for the text content if the charset is not
+specified in the `Content-Type` header of the request. Defaults to `utf-8`.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `txt`), a mime type (like
+`text/plain`), or a mime type with a wildcard (like `*/*` or `text/*`).
+If a function, the `type` option is called as `fn(req)` and the request is
+parsed if it returns a truthy value. Defaults to `text/plain`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+### bodyParser.urlencoded([options])
+
+Returns middleware that only parses `urlencoded` bodies and only looks at
+requests where the `Content-Type` header matches the `type` option. This
+parser accepts only UTF-8 encoding of the body and supports automatic
+inflation of `gzip` and `deflate` encodings.
+
+A new `body` object containing the parsed data is populated on the `request`
+object after the middleware (i.e. `req.body`). This object will contain
+key-value pairs, where the value can be a string or array (when `extended` is
+`false`), or any type (when `extended` is `true`).
+
+#### Options
+
+The `urlencoded` function takes an optional `options` object that may contain
+any of the following keys:
+
+##### extended
+
+The `extended` option allows to choose between parsing the URL-encoded data
+with the `querystring` library (when `false`) or the `qs` library (when
+`true`). The "extended" syntax allows for rich objects and arrays to be
+encoded into the URL-encoded format, allowing for a JSON-like experience
+with URL-encoded. For more information, please
+[see the qs library](https://www.npmjs.org/package/qs#readme).
+
+Defaults to `true`, but using the default has been deprecated. Please
+research into the difference between `qs` and `querystring` and choose the
+appropriate setting.
+
+##### inflate
+
+When set to `true`, then deflated (compressed) bodies will be inflated; when
+`false`, deflated bodies are rejected. Defaults to `true`.
+
+##### limit
+
+Controls the maximum request body size. If this is a number, then the value
+specifies the number of bytes; if it is a string, the value is passed to the
+[bytes](https://www.npmjs.com/package/bytes) library for parsing. Defaults
+to `'100kb'`.
+
+##### parameterLimit
+
+The `parameterLimit` option controls the maximum number of parameters that
+are allowed in the URL-encoded data. If a request contains more parameters
+than this value, a 413 will be returned to the client. Defaults to `1000`.
+
+##### type
+
+The `type` option is used to determine what media type the middleware will
+parse. This option can be a function or a string. If a string, `type` option
+is passed directly to the [type-is](https://www.npmjs.org/package/type-is#readme)
+library and this can be an extension name (like `urlencoded`), a mime type (like
+`application/x-www-form-urlencoded`), or a mime type with a wildcard (like
+`*/x-www-form-urlencoded`). If a function, the `type` option is called as
+`fn(req)` and the request is parsed if it returns a truthy value. Defaults
+to `application/x-www-form-urlencoded`.
+
+##### verify
+
+The `verify` option, if supplied, is called as `verify(req, res, buf, encoding)`,
+where `buf` is a `Buffer` of the raw request body and `encoding` is the
+encoding of the request. The parsing can be aborted by throwing an error.
+
+## Errors
+
+The middlewares provided by this module create errors depending on the error
+condition during parsing. The errors will typically have a `status`/`statusCode`
+property that contains the suggested HTTP response code, an `expose` property
+to determine if the `message` property should be displayed to the client, a
+`type` property to determine the type of error without matching against the
+`message`, and a `body` property containing the read body, if available.
+
+The following are the common errors emitted, though any error can come through
+for various reasons.
+
+### content encoding unsupported
+
+This error will occur when the request had a `Content-Encoding` header that
+contained an encoding but the "inflation" option was set to `false`. The
+`status` property is set to `415`, the `type` property is set to
+`'encoding.unsupported'`, and the `charset` property will be set to the
+encoding that is unsupported.
+
+### request aborted
+
+This error will occur when the request is aborted by the client before reading
+the body has finished. The `received` property will be set to the number of
+bytes received before the request was aborted and the `expected` property is
+set to the number of expected bytes. The `status` property is set to `400`
+and `type` property is set to `'request.aborted'`.
+
+### request entity too large
+
+This error will occur when the request body's size is larger than the "limit"
+option. The `limit` property will be set to the byte limit and the `length`
+property will be set to the request body's length. The `status` property is
+set to `413` and the `type` property is set to `'entity.too.large'`.
+
+### request size did not match content length
+
+This error will occur when the request's length did not match the length from
+the `Content-Length` header. This typically occurs when the request is malformed,
+typically when the `Content-Length` header was calculated based on characters
+instead of bytes. The `status` property is set to `400` and the `type` property
+is set to `'request.size.invalid'`.
+
+### stream encoding should not be set
+
+This error will occur when something called the `req.setEncoding` method prior
+to this middleware. This module operates directly on bytes only and you cannot
+call `req.setEncoding` when using this module. The `status` property is set to
+`500` and the `type` property is set to `'stream.encoding.set'`.
+
+### too many parameters
+
+This error will occur when the content of the request exceeds the configured
+`parameterLimit` for the `urlencoded` parser. The `status` property is set to
+`413` and the `type` property is set to `'parameters.too.many'`.
+
+### unsupported charset "BOGUS"
+
+This error will occur when the request had a charset parameter in the
+`Content-Type` header, but the `iconv-lite` module does not support it OR the
+parser does not support it. The charset is contained in the message as well
+as in the `charset` property. The `status` property is set to `415`, the
+`type` property is set to `'charset.unsupported'`, and the `charset` property
+is set to the charset that is unsupported.
+
+### unsupported content encoding "bogus"
+
+This error will occur when the request had a `Content-Encoding` header that
+contained an unsupported encoding. The encoding is contained in the message
+as well as in the `encoding` property. The `status` property is set to `415`,
+the `type` property is set to `'encoding.unsupported'`, and the `encoding`
+property is set to the encoding that is unsupported.
+
+## Examples
+
+### Express/Connect top-level generic
+
+This example demonstrates adding a generic JSON and URL-encoded parser as a
+top-level middleware, which will parse the bodies of all incoming requests.
+This is the simplest setup.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse application/x-www-form-urlencoded
+app.use(bodyParser.urlencoded({ extended: false }))
+
+// parse application/json
+app.use(bodyParser.json())
+
+app.use(function (req, res) {
+  res.setHeader('Content-Type', 'text/plain')
+  res.write('you posted:\n')
+  res.end(JSON.stringify(req.body, null, 2))
+})
+```
+
+### Express route-specific
+
+This example demonstrates adding body parsers specifically to the routes that
+need them. In general, this is the most recommended way to use body-parser with
+Express.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// create application/json parser
+var jsonParser = bodyParser.json()
+
+// create application/x-www-form-urlencoded parser
+var urlencodedParser = bodyParser.urlencoded({ extended: false })
+
+// POST /login gets urlencoded bodies
+app.post('/login', urlencodedParser, function (req, res) {
+  if (!req.body) return res.sendStatus(400)
+  res.send('welcome, ' + req.body.username)
+})
+
+// POST /api/users gets JSON bodies
+app.post('/api/users', jsonParser, function (req, res) {
+  if (!req.body) return res.sendStatus(400)
+  // create user in req.body
+})
+```
+
+### Change accepted type for parsers
+
+All the parsers accept a `type` option which allows you to change the
+`Content-Type` that the middleware will parse.
+
+```js
+var express = require('express')
+var bodyParser = require('body-parser')
+
+var app = express()
+
+// parse various different custom JSON types as JSON
+app.use(bodyParser.json({ type: 'application/*+json' }))
+
+// parse some custom thing into a Buffer
+app.use(bodyParser.raw({ type: 'application/vnd.custom-type' }))
+
+// parse an HTML body into a string
+app.use(bodyParser.text({ type: 'text/html' }))
+```

+
+Utility to parse a string bytes (ex: `1TB`) to bytes (`1099511627776`) and vice-versa.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install bytes
+```
+
+## Usage
+
+```js
+var bytes = require('bytes');
+```
+
+#### bytes.format(number value, [options]): string｜null
+
+Format the given value in bytes into a string. If the value is negative, it is kept as such. If it is a float, it is
+ rounded.
+
+**Arguments**
+
+| Name    | Type     | Description        |
+|---------|----------|--------------------|
+| value   | `number` | Value in bytes     |
+| options | `Object` | Conversion options |
+
+**Options**
+
+| Property          | Type   | Description                                                                             |
+|-------------------|--------|-----------------------------------------------------------------------------------------|
+| decimalPlaces | `number`｜`null` | Maximum number of decimal places to include in output. Default value to `2`. |
+| fixedDecimals | `boolean`｜`null` | Whether to always display the maximum number of decimal places. Default value to `false` |
+| thousandsSeparator | `string`｜`null` | Example of values: `' '`, `','` and `.`... Default value to `''`. |
+| unit | `string`｜`null` | The unit in which the result will be returned (B/KB/MB/GB/TB). Default value to `''` (which means auto detect). |
+| unitSeparator | `string`｜`null` | Separator to use between number and unit. Default value to `''`. |
+
+**Returns**
+
+| Name    | Type             | Description                                     |
+|---------|------------------|-------------------------------------------------|
+| results | `string`｜`null` | Return null upon error. String value otherwise. |
+
+**Example**
+
+```js
+bytes(1024);
+// output: '1KB'
+
+bytes(1000);
+// output: '1000B'
+
+bytes(1000, {thousandsSeparator: ' '});
+// output: '1 000B'
+
+bytes(1024 * 1.7, {decimalPlaces: 0});
+// output: '2KB'
+
+bytes(1024, {unitSeparator: ' '});
+// output: '1 KB'
+
+```
+
+#### bytes.parse(string｜number value): number｜null
+
+Parse the string value into an integer in bytes. If no unit is given, or `value`
+is a number, it is assumed the value is in bytes.
+
+Supported units and abbreviations are as follows and are case-insensitive:
+
+  * `b` for bytes
+  * `kb` for kilobytes
+  * `mb` for megabytes
+  * `gb` for gigabytes
+  * `tb` for terabytes
+
+The units are in powers of two, not ten. This means 1kb = 1024b according to this parser.
+
+**Arguments**
+
+| Name          | Type   | Description        |
+|---------------|--------|--------------------|
+| value   | `string`｜`number` | String to parse, or number in bytes.   |
+
+**Returns**
+
+| Name    | Type        | Description             |
+|---------|-------------|-------------------------|
+| results | `number`｜`null` | Return null upon error. Value in bytes otherwise. |
+
+**Example**
+
+```js
+bytes('1KB');
+// output: 1024
+
+bytes('1024');
+// output: 1024
+
+bytes(1024);
+// output: 1024
+```

+# Emitter [![Build Status](https://travis-ci.org/component/emitter.png)](https://travis-ci.org/component/emitter)
+
+  Event emitter component.
+
+## Installation
+
+```
+$ component install component/emitter
+```
+
+## API
+
+### Emitter(obj)
+
+  The `Emitter` may also be used as a mixin. For example
+  a "plain" object may become an emitter, or you may
+  extend an existing prototype.
+
+  As an `Emitter` instance:
+
+```js
+var Emitter = require('emitter');
+var emitter = new Emitter;
+emitter.emit('something');
+```
+
+  As a mixin:
+
+```js
+var Emitter = require('emitter');
+var user = { name: 'tobi' };
+Emitter(user);
+
+user.emit('im a user');
+```
+
+  As a prototype mixin:
+
+```js
+var Emitter = require('emitter');
+Emitter(User.prototype);
+```
+
+### Emitter#on(event, fn)
+
+  Register an `event` handler `fn`.
+
+### Emitter#once(event, fn)
+
+  Register a single-shot `event` handler `fn`,
+  removed immediately after it is invoked the
+  first time.
+
+### Emitter#off(event, fn)
+
+  * Pass `event` and `fn` to remove a listener.
+  * Pass `event` to remove all listeners on that event.
+  * Pass nothing to remove all listeners on all events.
+
+### Emitter#emit(event, ...)
+
+  Emit an `event` with variable option args.
+
+### Emitter#listeners(event)
+
+  Return an array of callbacks, or an empty array.
+
+### Emitter#hasListeners(event)
+
+  Check if this emitter has `event` handlers.

+
+Create and parse HTTP `Content-Disposition` header
+
+## Installation
+
+```sh
+$ npm install content-disposition
+```
+
+## API
+
+```js
+var contentDisposition = require('content-disposition')
+```
+
+### contentDisposition(filename, options)
+
+Create an attachment `Content-Disposition` header value using the given file name,
+if supplied. The `filename` is optional and if no file name is desired, but you
+want to specify `options`, set `filename` to `undefined`.
+
+```js
+res.setHeader('Content-Disposition', contentDisposition('∫ maths.pdf'))
+```
+
+**note** HTTP headers are of the ISO-8859-1 character set. If you are writing this
+header through a means different from `setHeader` in Node.js, you'll want to specify
+the `'binary'` encoding in Node.js.
+
+#### Options
+
+`contentDisposition` accepts these properties in the options object.
+
+##### fallback
+
+If the `filename` option is outside ISO-8859-1, then the file name is actually
+stored in a supplemental field for clients that support Unicode file names and
+a ISO-8859-1 version of the file name is automatically generated.
+
+This specifies the ISO-8859-1 file name to override the automatic generation or
+disables the generation all together, defaults to `true`.
+
+  - A string will specify the ISO-8859-1 file name to use in place of automatic
+    generation.
+  - `false` will disable including a ISO-8859-1 file name and only include the
+    Unicode version (unless the file name is already ISO-8859-1).
+  - `true` will enable automatic generation if the file name is outside ISO-8859-1.
+
+If the `filename` option is ISO-8859-1 and this option is specified and has a
+different value, then the `filename` option is encoded in the extended field
+and this set as the fallback field, even though they are both ISO-8859-1.
+
+##### type
+
+Specifies the disposition type, defaults to `"attachment"`. This can also be
+`"inline"`, or any other value (all values except inline are treated like
+`attachment`, but can convey additional information if both parties agree to
+it). The type is normalized to lower-case.
+
+### contentDisposition.parse(string)
+
+```js
+var disposition = contentDisposition.parse('attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt');
+```
+
+Parse a `Content-Disposition` header string. This automatically handles extended
+("Unicode") parameters by decoding them and providing them under the standard
+parameter name. This will return an object with the following properties (examples
+are shown for the string `'attachment; filename="EURO rates.txt"; filename*=UTF-8\'\'%e2%82%ac%20rates.txt'`):
+
+ - `type`: The disposition type (always lower case). Example: `'attachment'`
+
+ - `parameters`: An object of the parameters in the disposition (name of parameter
+   always lower case and extended versions replace non-extended versions). Example:
+   `{filename: "€ rates.txt"}`
+
+## Examples
+
+### Send a file for download
+
+```js
+var contentDisposition = require('content-disposition')
+var destroy = require('destroy')
+var http = require('http')
+var onFinished = require('on-finished')
+
+var filePath = '/path/to/public/plans.pdf'
+
+http.createServer(function onRequest(req, res) {
+  // set headers
+  res.setHeader('Content-Type', 'application/pdf')
+  res.setHeader('Content-Disposition', contentDisposition(filePath))
+
+  // send file
+  var stream = fs.createReadStream(filePath)
+  stream.pipe(res)
+  onFinished(res, function (err) {
+    destroy(stream)
+  })
+})
+```

+
+Create and parse HTTP Content-Type header according to RFC 7231
+
+## Installation
+
+```sh
+$ npm install content-type
+```
+
+## API
+
+```js
+var contentType = require('content-type')
+```
+
+### contentType.parse(string)
+
+```js
+var obj = contentType.parse('image/svg+xml; charset=utf-8')
+```
+
+Parse a content type string. This will return an object with the following
+properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The media type (the type and subtype, always lower case).
+   Example: `'image/svg+xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of parameter
+   always lower case). Example: `{charset: 'utf-8'}`
+
+Throws a `TypeError` if the string is missing or invalid.
+
+### contentType.parse(req)
+
+```js
+var obj = contentType.parse(req)
+```
+
+Parse the `content-type` header from the given `req`. Short-cut for
+`contentType.parse(req.headers['content-type'])`.
+
+Throws a `TypeError` if the `Content-Type` header is missing or invalid.
+
+### contentType.parse(res)
+
+```js
+var obj = contentType.parse(res)
+```
+
+Parse the `content-type` header set on the given `res`. Short-cut for
+`contentType.parse(res.getHeader('content-type'))`.
+
+Throws a `TypeError` if the `Content-Type` header is missing or invalid.
+
+### contentType.format(obj)
+
+```js
+var str = contentType.format({type: 'image/svg+xml'})
+```
+
+Format an object into a content type string. This will return a string of the
+content type for the given object with the following properties (examples are
+shown that produce the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The media type (will be lower-cased). Example: `'image/svg+xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of the
+   parameter will be lower-cased). Example: `{charset: 'utf-8'}`
+
+Throws a `TypeError` if the object contains an invalid type or parameter names.

+
+Basic HTTP cookie parser and serializer for HTTP servers.
+
+## Installation
+
+```sh
+$ npm install cookie
+```
+
+## API
+
+```js
+var cookie = require('cookie');
+```
+
+### cookie.parse(str, options)
+
+Parse an HTTP `Cookie` header string and returning an object of all cookie name-value pairs.
+The `str` argument is the string representing a `Cookie` header value and `options` is an
+optional object containing additional parsing options.
+
+```js
+var cookies = cookie.parse('foo=bar; equation=E%3Dmc%5E2');
+// { foo: 'bar', equation: 'E=mc^2' }
+```
+
+#### Options
+
+`cookie.parse` accepts these properties in the options object.
+
+##### decode
+
+Specifies a function that will be used to decode a cookie's value. Since the value of a cookie
+has a limited character set (and must be a simple string), this function can be used to decode
+a previously-encoded cookie value into a JavaScript string or other object.
+
+The default function is the global `decodeURIComponent`, which will decode any URL-encoded
+sequences into their byte representations.
+
+**note** if an error is thrown from this function, the original, non-decoded cookie value will
+be returned as the cookie's value.
+
+### cookie.serialize(name, value, options)
+
+Serialize a cookie name-value pair into a `Set-Cookie` header string. The `name` argument is the
+name for the cookie, the `value` argument is the value to set the cookie to, and the `options`
+argument is an optional object containing additional serialization options.
+
+```js
+var setCookie = cookie.serialize('foo', 'bar');
+// foo=bar
+```
+
+#### Options
+
+`cookie.serialize` accepts these properties in the options object.
+
+##### domain
+
+Specifies the value for the [`Domain` `Set-Cookie` attribute][rfc-6266-5.2.3]. By default, no
+domain is set, and most clients will consider the cookie to apply to only the current domain.
+
+##### encode
+
+Specifies a function that will be used to encode a cookie's value. Since value of a cookie
+has a limited character set (and must be a simple string), this function can be used to encode
+a value into a string suited for a cookie's value.
+
+The default function is the global `ecodeURIComponent`, which will encode a JavaScript string
+into UTF-8 byte sequences and then URL-encode any that fall outside of the cookie range.
+
+##### expires
+
+Specifies the `Date` object to be the value for the [`Expires` `Set-Cookie` attribute][rfc-6266-5.2.1].
+By default, no expiration is set, and most clients will consider this a "non-persistent cookie" and
+will delete it on a condition like exiting a web browser application.
+
+**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
+`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### httpOnly
+
+Specifies the `boolean` value for the [`HttpOnly` `Set-Cookie` attribute][rfc-6266-5.2.6]. When truthy,
+the `HttpOnly` attribute is set, otherwise it is not. By default, the `HttpOnly` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not allow client-side
+JavaScript to see the cookie in `document.cookie`.
+
+##### maxAge
+
+Specifies the `number` (in seconds) to be the value for the [`Max-Age` `Set-Cookie` attribute][rfc-6266-5.2.2].
+The given number will be converted to an integer by rounding down. By default, no maximum age is set.
+
+**note** the [cookie storage model specification][rfc-6266-5.3] states that if both `expires` and
+`magAge` are set, then `maxAge` takes precedence, but it is possiblke not all clients by obey this,
+so if both are set, they should point to the same date and time.
+
+##### path
+
+Specifies the value for the [`Path` `Set-Cookie` attribute][rfc-6266-5.2.4]. By default, the path
+is considered the ["default path"][rfc-6266-5.1.4]. By default, no maximum age is set, and most
+clients will consider this a "non-persistent cookie" and will delete it on a condition like exiting
+a web browser application.
+
+##### sameSite
+
+Specifies the `boolean` or `string` to be the value for the [`SameSite` `Set-Cookie` attribute][draft-west-first-party-cookies-07].
+
+  - `true` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+  - `false` will not set the `SameSite` attribute.
+  - `'lax'` will set the `SameSite` attribute to `Lax` for lax same site enforcement.
+  - `'strict'` will set the `SameSite` attribute to `Strict` for strict same site enforcement.
+
+More information about the different enforcement levels can be found in the specification
+https://tools.ietf.org/html/draft-west-first-party-cookies-07#section-4.1.1
+
+**note** This is an attribute that has not yet been fully standardized, and may change in the future.
+This also means many clients may ignore this attribute until they understand it.
+
+##### secure
+
+Specifies the `boolean` value for the [`Secure` `Set-Cookie` attribute][rfc-6266-5.2.5]. When truthy,
+the `Secure` attribute is set, otherwise it is not. By default, the `Secure` attribute is not set.
+
+**note** be careful when setting this to `true`, as compliant clients will not send the cookie back to
+the server in the future if the browser does not have an HTTPS connection.
+
+## Example
+
+The following example uses this module in conjunction with the Node.js core HTTP server
+to prompt a user for their name and display it back on future visits.
+
+```js
+var cookie = require('cookie');
+var escapeHtml = require('escape-html');
+var http = require('http');
+var url = require('url');
+
+function onRequest(req, res) {
+  // Parse the query string
+  var query = url.parse(req.url, true, true).query;
+
+  if (query && query.name) {
+    // Set a new cookie with the name
+    res.setHeader('Set-Cookie', cookie.serialize('name', String(query.name), {
+      httpOnly: true,
+      maxAge: 60 * 60 * 24 * 7 // 1 week
+    }));
+
+    // Redirect back after setting cookie
+    res.statusCode = 302;
+    res.setHeader('Location', req.headers.referer || '/');
+    res.end();
+    return;
+  }
+
+  // Parse the cookies on the request
+  var cookies = cookie.parse(req.headers.cookie || '');
+
+  // Get the visitor name set in the cookie
+  var name = cookies.name;
+
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8');
+
+  if (name) {
+    res.write('<p>Welcome back, <b>' + escapeHtml(name) + '</b>!</p>');
+  } else {
+    res.write('<p>Hello, new visitor!</p>');
+  }
+
+  res.write('<form method="GET">');
+  res.write('<input placeholder="enter your name" name="name"> <input type="submit" value="Set Name">');
+  res.end('</form');
+}
+
+http.createServer(onRequest).listen(3000);
+```

+
+
+
+A tiny node.js debugging utility modelled after node core's debugging technique.
+
+**Discussion around the V3 API is under way [here](https://github.com/visionmedia/debug/issues/370)**
+
+## Installation
+
+```bash
+$ npm install debug
+```
+
+## Usage
+
+`debug` exposes a function; simply pass this function the name of your module, and it will return a decorated version of `console.error` for you to pass debug statements to. This will allow you to toggle the debug output for different parts of your module as well as the module as a whole.
+
+Example _app.js_:
+
+```js
+var debug = require('debug')('http')
+  , http = require('http')
+  , name = 'My App';
+
+// fake app
+
+debug('booting %s', name);
+
+http.createServer(function(req, res){
+  debug(req.method + ' ' + req.url);
+  res.end('hello\n');
+}).listen(3000, function(){
+  debug('listening');
+});
+
+// fake worker of some kind
+
+require('./worker');
+```
+
+Example _worker.js_:
+
+```js
+var debug = require('debug')('worker');
+
+setInterval(function(){
+  debug('doing some work');
+}, 1000);
+```
+
+ The __DEBUG__ environment variable is then used to enable these based on space or comma-delimited names. Here are some examples:
+
+  ![debug http and worker](http://f.cl.ly/items/18471z1H402O24072r1J/Screenshot.png)
+
+  ![debug worker](http://f.cl.ly/items/1X413v1a3M0d3C2c1E0i/Screenshot.png)
+
+#### Windows note
+
+ On Windows the environment variable is set using the `set` command.
+
+ ```cmd
+ set DEBUG=*,-not_this
+ ```
+
+ Note that PowerShell uses different syntax to set environment variables.
+
+ ```cmd
+ $env:DEBUG = "*,-not_this"
+  ```
+
+Then, run the program to be debugged as usual.
+
+## Millisecond diff
+
+  When actively developing an application it can be useful to see when the time spent between one `debug()` call and the next. Suppose for example you invoke `debug()` before requesting a resource, and after as well, the "+NNNms" will show you how much time was spent between calls.
+
+  ![](http://f.cl.ly/items/2i3h1d3t121M2Z1A3Q0N/Screenshot.png)
+
+  When stdout is not a TTY, `Date#toUTCString()` is used, making it more useful for logging the debug information as shown below:
+
+  ![](http://f.cl.ly/items/112H3i0e0o0P0a2Q2r11/Screenshot.png)
+
+## Conventions
+
+  If you're using this in one or more of your libraries, you _should_ use the name of your library so that developers may toggle debugging as desired without guessing names. If you have more than one debuggers you _should_ prefix them with your library name and use ":" to separate features. For example "bodyParser" from Connect would then be "connect:bodyParser".
+
+## Wildcards
+
+  The `*` character may be used as a wildcard. Suppose for example your library has debuggers named "connect:bodyParser", "connect:compress", "connect:session", instead of listing all three with `DEBUG=connect:bodyParser,connect:compress,connect:session`, you may simply do `DEBUG=connect:*`, or to run everything using this module simply use `DEBUG=*`.
+
+  You can also exclude specific debuggers by prefixing them with a "-" character.  For example, `DEBUG=*,-connect:*` would include all debuggers except those starting with "connect:".
+
+## Environment Variables
+
+  When running through Node.js, you can set a few environment variables that will
+  change the behavior of the debug logging:
+
+| Name      | Purpose                                         |
+|-----------|-------------------------------------------------|
+| `DEBUG`   | Enables/disables specific debugging namespaces. |
+| `DEBUG_COLORS`| Whether or not to use colors in the debug output. |
+| `DEBUG_DEPTH` | Object inspection depth. |
+| `DEBUG_SHOW_HIDDEN` | Shows hidden properties on inspected objects. |
+
+
+  __Note:__ The environment variables beginning with `DEBUG_` end up being
+  converted into an Options object that gets used with `%o`/`%O` formatters.
+  See the Node.js documentation for
+  [`util.inspect()`](https://nodejs.org/api/util.html#util_util_inspect_object_options)
+  for the complete list.
+
+## Formatters
+
+
+  Debug uses [printf-style](https://wikipedia.org/wiki/Printf_format_string) formatting. Below are the officially supported formatters:
+
+| Formatter | Representation |
+|-----------|----------------|
+| `%O`      | Pretty-print an Object on multiple lines. |
+| `%o`      | Pretty-print an Object all on a single line. |
+| `%s`      | String. |
+| `%d`      | Number (both integer and float). |
+| `%j`      | JSON. Replaced with the string '[Circular]' if the argument contains circular references. |
+| `%%`      | Single percent sign ('%'). This does not consume an argument. |
+
+### Custom formatters
+
+  You can add custom formatters by extending the `debug.formatters` object. For example, if you wanted to add support for rendering a Buffer as hex with `%h`, you could do something like:
+
+```js
+const createDebug = require('debug')
+createDebug.formatters.h = (v) => {
+  return v.toString('hex')
+}
+
+// …elsewhere
+const debug = createDebug('foo')
+debug('this is hex: %h', new Buffer('hello world'))
+//   foo this is hex: 68656c6c6f20776f726c6421 +0ms
+```
+
+## Browser support
+  You can build a browser-ready script using [browserify](https://github.com/substack/node-browserify),
+  or just use the [browserify-as-a-service](https://wzrd.in/) [build](https://wzrd.in/standalone/debug@latest),
+  if you don't want to build it yourself.
+
+  Debug's enable state is currently persisted by `localStorage`.
+  Consider the situation shown below where you have `worker:a` and `worker:b`,
+  and wish to debug both. You can enable this using `localStorage.debug`:
+
+```js
+localStorage.debug = 'worker:*'
+```
+
+And then refresh the page.
+
+```js
+a = debug('worker:a');
+b = debug('worker:b');
+
+setInterval(function(){
+  a('doing some work');
+}, 1000);
+
+setInterval(function(){
+  b('doing some work');
+}, 1200);
+```
+
+#### Web Inspector Colors
+
+  Colors are also enabled on "Web Inspectors" that understand the `%c` formatting
+  option. These are WebKit web inspectors, Firefox ([since version
+  31](https://hacks.mozilla.org/2014/05/editable-box-model-multiple-selection-sublime-text-keys-much-more-firefox-developer-tools-episode-31/))
+  and the Firebug plugin for Firefox (any version).
+
+  Colored output looks something like:
+
+  ![](https://cloud.githubusercontent.com/assets/71256/3139768/b98c5fd8-e8ef-11e3-862a-f7253b6f47c6.png)
+
+
+## Output streams
+
+  By default `debug` will log to stderr, however this can be configured per-namespace by overriding the `log` method:
+
+Example _stdout.js_:
+
+```js
+var debug = require('debug');
+var error = debug('app:error');
+
+// by default stderr is used
+error('goes to stderr!');
+
+var log = debug('app:log');
+// set this namespace to log via console.log
+log.log = console.log.bind(console); // don't forget to bind to console!
+log('goes to stdout');
+error('still goes to stderr!');
+
+// set all output to go via console.info
+// overrides all per-namespace log settings
+debug.log = console.info.bind(console);
+error('now goes to stdout via console.info');
+log('still goes to stdout, but via console.info now');
+```

+Deprecate all the things

+> With great modules comes great responsibility; mark things deprecated!
+
+## Install
+
+This module is installed directly using `npm`:
+
+```sh
+$ npm install depd
+```
+
+This module can also be bundled with systems like
+[Browserify](http://browserify.org/) or [webpack](https://webpack.github.io/),
+though by default this module will alter it's API to no longer display or
+track deprecations.
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var deprecate = require('depd')('my-module')
+```
+
+This library allows you to display deprecation messages to your users.
+This library goes above and beyond with deprecation warnings by
+introspection of the call stack (but only the bits that it is interested
+in).
+
+Instead of just warning on the first invocation of a deprecated
+function and never again, this module will warn on the first invocation
+of a deprecated function per unique call site, making it ideal to alert
+users of all deprecated uses across the code base, rather than just
+whatever happens to execute first.
+
+The deprecation warnings from this module also include the file and line
+information for the call into the module that the deprecated function was
+in.
+
+**NOTE** this library has a similar interface to the `debug` module, and
+this module uses the calling file to get the boundary for the call stacks,
+so you should always create a new `deprecate` object in each file and not
+within some central file.
+
+### depd(namespace)
+
+Create a new deprecate function that uses the given namespace name in the
+messages and will display the call site prior to the stack entering the
+file this function was called from. It is highly suggested you use the
+name of your module as the namespace.
+
+### deprecate(message)
+
+Call this function from deprecated code to display a deprecation message.
+This message will appear once per unique caller site. Caller site is the
+first call site in the stack in a different file from the caller of this
+function.
+
+If the message is omitted, a message is generated for you based on the site
+of the `deprecate()` call and will display the name of the function called,
+similar to the name displayed in a stack trace.
+
+### deprecate.function(fn, message)
+
+Call this function to wrap a given function in a deprecation message on any
+call to the function. An optional message can be supplied to provide a custom
+message.
+
+### deprecate.property(obj, prop, message)
+
+Call this function to wrap a given property on object in a deprecation message
+on any accessing or setting of the property. An optional message can be supplied
+to provide a custom message.
+
+The method must be called on the object where the property belongs (not
+inherited from the prototype).
+
+If the property is a data descriptor, it will be converted to an accessor
+descriptor in order to display the deprecation message.
+
+### process.on('deprecation', fn)
+
+This module will allow easy capturing of deprecation errors by emitting the
+errors as the type "deprecation" on the global `process`. If there are no
+listeners for this type, the errors are written to STDERR as normal, but if
+there are any listeners, nothing will be written to STDERR and instead only
+emitted. From there, you can write the errors in a different format or to a
+logging source.
+
+The error represents the deprecation and is emitted only once with the same
+rules as writing to STDERR. The error has the following properties:
+
+  - `message` - This is the message given by the library
+  - `name` - This is always `'DeprecationError'`
+  - `namespace` - This is the namespace the deprecation came from
+  - `stack` - This is the stack of the call to the deprecated thing
+
+Example `error.stack` output:
+
+```
+DeprecationError: my-cool-module deprecated oldfunction
+    at Object.<anonymous> ([eval]-wrapper:6:22)
+    at Module._compile (module.js:456:26)
+    at evalScript (node.js:532:25)
+    at startup (node.js:80:7)
+    at node.js:902:3
+```
+
+### process.env.NO_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `NO_DEPRECATION`
+is provided as a quick solution to silencing deprecation warnings from being
+output. The format of this is similar to that of `DEBUG`:
+
+```sh
+$ NO_DEPRECATION=my-module,othermod node app.js
+```
+
+This will suppress deprecations from being output for "my-module" and "othermod".
+The value is a list of comma-separated namespaces. To suppress every warning
+across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--no-deprecation` to the `node` executable will suppress
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not suppress the deperecations given to any "deprecation"
+event listeners, just the output to STDERR.
+
+### process.env.TRACE_DEPRECATION
+
+As a user of modules that are deprecated, the environment variable `TRACE_DEPRECATION`
+is provided as a solution to getting more detailed location information in deprecation
+warnings by including the entire stack trace. The format of this is the same as
+`NO_DEPRECATION`:
+
+```sh
+$ TRACE_DEPRECATION=my-module,othermod node app.js
+```
+
+This will include stack traces for deprecations being output for "my-module" and
+"othermod". The value is a list of comma-separated namespaces. To trace every
+warning across all namespaces, use the value `*` for a namespace.
+
+Providing the argument `--trace-deprecation` to the `node` executable will trace
+all deprecations (only available in Node.js 0.8 or higher).
+
+**NOTE** This will not trace the deperecations silenced by `NO_DEPRECATION`.
+
+## Display
+
+![message](files/message.png)
+
+When a user calls a function in your library that you mark deprecated, they
+will see the following written to STDERR (in the given colors, similar colors
+and layout to the `debug` module):
+
+```
+bright cyan    bright yellow
+|              |          reset       cyan

+               |          deprecation message
+               the word "deprecated"
+```
+
+If the user redirects their STDERR to a file or somewhere that does not support
+colors, they see (similar layout to the `debug` module):
+
+```

+```
+
+## Examples
+
+### Deprecating all calls to a function
+

+from "my-module" on STDERR.
+
+```js

+
+// message automatically derived from function name
+// Object.oldfunction
+exports.oldfunction = deprecate.function(function oldfunction () {
+  // all calls to function are deprecated
+})
+
+// specific message
+exports.oldfunction = deprecate.function(function () {
+  // all calls to function are deprecated
+}, 'oldfunction')
+```
+
+### Conditionally deprecating a function call
+
+This will display a deprecated message about "weirdfunction" being deprecated
+from "my-module" on STDERR when called with less than 2 arguments.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  }
+}
+```
+
+When calling `deprecate` as a function, the warning is counted per call site
+within your own module, so you can display different deprecations depending
+on different situations and the users will still get all the warnings:
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.weirdfunction = function () {
+  if (arguments.length < 2) {
+    // calls with 0 or 1 args are deprecated
+    deprecate('weirdfunction args < 2')
+  } else if (typeof arguments[0] !== 'string') {
+    // calls with non-string first argument are deprecated
+    deprecate('weirdfunction non-string first arg')
+  }
+}
+```
+
+### Deprecating property access
+
+This will display a deprecated message about "oldprop" being deprecated
+from "my-module" on STDERR when accessed. A deprecation will be displayed
+when setting the value and when getting the value.
+
+```js
+var deprecate = require('depd')('my-cool-module')
+
+exports.oldprop = 'something'
+
+// message automatically derives from property name
+deprecate.property(exports, 'oldprop')
+
+// explicit message
+deprecate.property(exports, 'oldprop', 'oldprop >= 0.10')
+```

+
+Destroy a stream.
+
+This module is meant to ensure a stream gets destroyed, handling different APIs
+and Node.js bugs.
+
+## API
+
+```js
+var destroy = require('destroy')
+```
+
+### destroy(stream)
+
+Destroy the given stream. In most cases, this is identical to a simple
+`stream.destroy()` call. The rules are as follows for a given stream:
+
+  1. If the `stream` is an instance of `ReadStream`, then call `stream.destroy()`
+     and add a listener to the `open` event to call `stream.close()` if it is
+     fired. This is for a Node.js bug that will leak a file descriptor if
+     `.destroy()` is called before `open`.
+  2. If the `stream` is not an instance of `Stream`, then nothing happens.
+  3. If the `stream` has a `.destroy()` method, then call it.
+
+The function returns the `stream` passed in as the argument.
+
+## Example
+
+```js
+var destroy = require('destroy')
+
+var fs = require('fs')
+var stream = fs.createReadStream('package.json')
+
+// ... and later
+destroy(stream)
+```

+Get the first event in a set of event emitters and event pairs,
+then clean up after itself.
+
+## Install
+
+```sh
+$ npm install ee-first
+```
+
+## API
+
+```js
+var first = require('ee-first')
+```
+
+### first(arr, listener)
+
+Invoke `listener` on the first event from the list specified in `arr`. `arr` is
+an array of arrays, with each array in the format `[ee, ...event]`. `listener`
+will be called only once, the first time any of the given events are emitted. If
+`error` is one of the listened events, then if that fires first, the `listener`
+will be given the `err` argument.
+
+The `listener` is invoked as `listener(err, ee, event, args)`, where `err` is the
+first argument emitted from an `error` event, if applicable; `ee` is the event
+emitter that fired; `event` is the string event name that fired; and `args` is an
+array of the arguments that were emitted on the event.
+
+```js
+var ee1 = new EventEmitter()
+var ee2 = new EventEmitter()
+
+first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+```
+
+#### .cancel()
+
+The group of listeners can be cancelled before being invoked and have all the event
+listeners removed from the underlying event emitters.
+
+```js
+var thunk = first([
+  [ee1, 'close', 'end', 'error'],
+  [ee2, 'error']
+], function (err, ee, event, args) {
+  // listener invoked
+})
+
+// cancel and clean up
+thunk.cancel()
+```

+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences
+
+## Installation
+
+```sh
+$ npm install encodeurl
+```
+
+## API
+
+```js
+var encodeUrl = require('encodeurl')
+```
+
+### encodeUrl(url)
+
+Encode a URL to a percent-encoded form, excluding already-encoded sequences.
+
+This function will take an already-encoded URL and encode all the non-URL
+code points (as UTF-8 byte sequences). This function will not encode the
+"%" character unless it is not part of a valid sequence (`%20` will be
+left as-is, but `%foo` will be encoded as `%25foo`).
+
+This encode is meant to be "safe" and does not throw errors. It will try as
+hard as it can to properly encode the given URL, including replacing any raw,
+unpaired surrogate pairs with the Unicode replacement character prior to
+encoding.
+
+This function is _similar_ to the intrinsic function `encodeURI`, except it
+will not encode the `%` character if that is part of a valid sequence, will
+not encode `[` and `]` (for IPv6 hostnames) and will replace raw, unpaired
+surrogate pairs with the Unicode replacement character (instead of throwing).
+
+## Examples
+
+### Encode a URL containing user-controled data
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+
+http.createServer(function onRequest (req, res) {
+  // get encoded form of inbound url
+  var url = encodeUrl(req.url)
+
+  // create html message
+  var body = '<p>Location ' + escapeHtml(url) + ' not found</p>'
+
+  // send a 404
+  res.statusCode = 404
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+  res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+  res.end(body, 'utf-8')
+})
+```
+
+### Encode a URL for use in a header field
+
+```js
+var encodeUrl = require('encodeurl')
+var escapeHtml = require('escape-html')
+var url = require('url')
+
+http.createServer(function onRequest (req, res) {
+  // parse inbound url
+  var href = url.parse(req)
+
+  // set new host for redirect
+  href.host = 'localhost'
+  href.protocol = 'https:'
+  href.slashes = true
+
+  // create location header
+  var location = encodeUrl(url.format(href))
+
+  // create html message
+  var body = '<p>Redirecting to new site: ' + escapeHtml(location) + '</p>'
+
+  // send a 301
+  res.statusCode = 301
+  res.setHeader('Content-Type', 'text/html; charset=UTF-8')
+  res.setHeader('Content-Length', String(Buffer.byteLength(body, 'utf-8')))
+  res.setHeader('Location', location)
+  res.end(body, 'utf-8')
+})
+```

+# Engine.IO client
+
+[![Build Status](https://travis-ci.org/socketio/engine.io-client.svg?branch=master)](http://travis-ci.org/socketio/engine.io-client)
+[![NPM version](https://badge.fury.io/js/engine.io-client.svg)](http://badge.fury.io/js/engine.io-client)
+
+This is the client for [Engine.IO](http://github.com/socketio/engine.io),
+the implementation of transport-based cross-browser/cross-device
+bi-directional communication layer for [Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Standalone
+
+You can find an `engine.io.js` file in this repository, which is a
+standalone build you can use as follows:
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+  // eio = Socket
+  var socket = eio('ws://localhost');
+  socket.on('open', function(){
+    socket.on('message', function(data){});
+    socket.on('close', function(){});
+  });
+</script>
+```
+
+### With browserify
+
+Engine.IO is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the client package
+
+    ```bash
+    $ npm install engine.io-client
+    ```
+
+1. write your app code
+
+    ```js
+    var socket = require('engine.io-client')('ws://localhost');
+    socket.on('open', function(){
+      socket.on('message', function(data){});
+      socket.on('close', function(){});
+    });
+    ```
+
+1. build your app bundle
+
+    ```bash
+    $ browserify app.js > bundle.js
+    ```
+
+1. include on your page
+
+    ```html
+    <script src="/path/to/bundle.js"></script>
+    ```
+
+### Sending and receiving binary
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+  var socket = new eio.Socket('ws://localhost/');
+  socket.binaryType = 'blob';
+  socket.on('open', function () {
+    socket.send(new Int8Array(5));
+    socket.on('message', function(blob){});
+    socket.on('close', function(){ });
+  });
+</script>
+```
+
+### Node.JS
+
+Add `engine.io-client` to your `package.json` and then:
+
+```js
+var socket = require('engine.io-client')('ws://localhost');
+socket.on('open', function(){
+  socket.on('message', function(data){});
+  socket.on('close', function(){});
+});
+```
+
+### Node.js with certificates
+```js
+var opts = {
+  key: fs.readFileSync('test/fixtures/client.key'),
+  cert: fs.readFileSync('test/fixtures/client.crt'),
+  ca: fs.readFileSync('test/fixtures/ca.crt')
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+  socket.on('message', function(data){});
+  socket.on('close', function(){});
+});
+```
+
+### Node.js with extraHeaders
+```js
+var opts = {
+  extraHeaders: {
+    'X-Custom-Header-For-My-Project': 'my-secret-access-token',
+    'Cookie': 'user_session=NI2JlCKF90aE0sJZD9ZzujtdsUqNYSBYxzlTsvdSUe35ZzdtVRGqYFr0kdGxbfc5gUOkR9RGp20GVKza; path=/; expires=Tue, 07-Apr-2015 18:18:08 GMT; secure; HttpOnly'
+  }
+};
+
+var socket = require('engine.io-client')('ws://localhost', opts);
+socket.on('open', function(){
+  socket.on('message', function(data){});
+  socket.on('close', function(){});
+});
+```
+
+## Features
+
+- Lightweight
+- Runs on browser and node.js seamlessly
+- Transports are independent of `Engine`
+  - Easy to debug
+  - Easy to unit test
+- Runs inside HTML5 WebWorker
+- Can send and receive binary data
+  - Receives as ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer
+    in Node
+  - When XHR2 or WebSockets are used, binary is emitted directly. Otherwise
+    binary is encoded into base64 strings, and decoded when binary types are
+    supported.
+  - With browsers that don't support ArrayBuffer, an object { base64: true,
+    data: dataAsBase64String } is emitted on the `message` event.
+
+## API
+
+### Socket
+
+The client class. Mixes in [Emitter](http://github.com/component/emitter).
+Exposed as `eio` in the browser standalone build.
+
+#### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `binaryType` _(String)_ : can be set to 'arraybuffer' or 'blob' in browsers,
+  and `buffer` or `arraybuffer` in Node. Blob is only used in browser if it's
+  supported.
+
+#### Events
+
+- `open`
+  - Fired upon successful connection.
+- `message`
+  - Fired when data is received from the server.
+  - **Arguments**
+    - `String` | `ArrayBuffer`: utf-8 encoded data or ArrayBuffer containing
+      binary data
+- `close`
+  - Fired upon disconnection. In compliance with the WebSocket API spec, this event may be
+    fired even if the `open` event does not occur (i.e. due to connection error or `close()`).
+- `error`
+  - Fired when an error occurs.
+- `flush`
+  - Fired upon completing a buffer flush
+- `drain`
+  - Fired after `drain` event of transport if writeBuffer is empty
+- `upgradeError`
+  - Fired if an error occurs with a transport we're trying to upgrade to.
+- `upgrade`
+  - Fired upon upgrade success, after the new transport is set
+- `ping`
+  - Fired upon _flushing_ a ping packet (ie: actual packet write out)
+- `pong`
+  - Fired upon receiving a pong packet.
+
+#### Methods
+
+- **constructor**
+    - Initializes the client
+    - **Parameters**
+      - `String` uri
+      - `Object`: optional, options object
+    - **Options**
+      - `agent` (`http.Agent`): `http.Agent` to use, defaults to `false` (NodeJS only)
+      - `upgrade` (`Boolean`): defaults to true, whether the client should try
+      to upgrade the transport from long-polling to something better.
+      - `forceJSONP` (`Boolean`): forces JSONP for polling transport.
+      - `jsonp` (`Boolean`): determines whether to use JSONP when
+        necessary for polling. If disabled (by settings to false) an error will
+        be emitted (saying "No transports available") if no other transports
+        are available. If another transport is available for opening a
+        connection (e.g. WebSocket) that transport
+        will be used instead.
+      - `forceBase64` (`Boolean`): forces base 64 encoding for polling transport even when XHR2 responseType is available and WebSocket even if the used standard supports binary.
+      - `enablesXDR` (`Boolean`): enables XDomainRequest for IE8 to avoid loading bar flashing with click sound. default to `false` because XDomainRequest has a flaw of not sending cookie.
+      - `timestampRequests` (`Boolean`): whether to add the timestamp with each
+        transport request. Note: polling requests are always stamped unless this
+        option is explicitly set to `false` (`false`)
+      - `timestampParam` (`String`): timestamp parameter (`t`)
+      - `policyPort` (`Number`): port the policy server listens on (`843`)
+      - `path` (`String`): path to connect to, default is `/engine.io`
+      - `transports` (`Array`): a list of transports to try (in order).
+      Defaults to `['polling', 'websocket']`. `Engine`
+      always attempts to connect directly with the first one, provided the
+      feature detection test for it passes.
+      - `transportOptions` (`Object`): hash of options, indexed by transport name, overriding the common options for the given transport
+      - `rememberUpgrade` (`Boolean`): defaults to false.
+        If true and if the previous websocket connection to the server succeeded,
+        the connection attempt will bypass the normal upgrade process and will initially
+        try websocket. A connection attempt following a transport error will use the
+        normal upgrade process. It is recommended you turn this on only when using
+        SSL/TLS connections, or if you know that your network does not block websockets.
+      - `pfx` (`String`): Certificate, Private key and CA certificates to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+      - `key` (`String`): Private key to use for SSL. Can be used in Node.js client environment to manually specify certificate information.
+      - `passphrase` (`String`): A string of passphrase for the private key or pfx. Can be used in Node.js client environment to manually specify certificate information.
+      - `cert` (`String`): Public x509 certificate to use. Can be used in Node.js client environment to manually specify certificate information.
+      - `ca` (`String`|`Array`): An authority certificate or array of authority certificates to check the remote host against.. Can be used in Node.js client environment to manually specify certificate information.
+      - `ciphers` (`String`): A string describing the ciphers to use or exclude. Consult the [cipher format list](http://www.openssl.org/docs/apps/ciphers.html#CIPHER_LIST_FORMAT) for details on the format. Can be used in Node.js client environment to manually specify certificate information.
+      - `rejectUnauthorized` (`Boolean`): If true, the server certificate is verified against the list of supplied CAs. An 'error' event is emitted if verification fails. Verification happens at the connection level, before the HTTP request is sent. Can be used in Node.js client environment to manually specify certificate information.
+      - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+        (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
+        - `threshold` (`Number`): data is compressed only if the byte size is above this value. This option is ignored on the browser. (`1024`)
+      - `extraHeaders` (`Object`): Headers that will be passed for each request to the server (via xhr-polling and via websockets). These values then can be used during handshake or for special proxies. Can only be used in Node.js client environment.
+      - `onlyBinaryUpgrades` (`Boolean`): whether transport upgrades should be restricted to transports supporting binary data (`false`)
+      - `forceNode` (`Boolean`): Uses NodeJS implementation for websockets - even if there is a native Browser-Websocket available, which is preferred by default over the NodeJS implementation. (This is useful when using hybrid platforms like nw.js or electron) (`false`, NodeJS only)
+      - `localAddress` (`String`): the local IP address to connect to
+    - **Polling-only options**
+      - `requestTimeout` (`Number`): Timeout for xhr-polling requests in milliseconds (`0`)
+    - **Websocket-only options**
+      - `protocols` (`Array`): a list of subprotocols (see [MDN reference](https://developer.mozilla.org/en-US/docs/Web/API/WebSockets_API/Writing_WebSocket_servers#Subprotocols))
+- `send`
+    - Sends a message to the server
+    - **Parameters**
+      - `String` | `ArrayBuffer` | `ArrayBufferView` | `Blob`: data to send
+      - `Object`: optional, options object
+      - `Function`: optional, callback upon `drain`
+    - **Options**
+      - `compress` (`Boolean`): whether to compress sending data. This option is ignored and forced to be `true` on the browser. (`true`)
+- `close`
+    - Disconnects the client.
+
+### Transport
+
+The transport class. Private. _Inherits from EventEmitter_.
+
+#### Events
+
+- `poll`: emitted by polling transports upon starting a new request
+- `pollComplete`: emitted by polling transports upon completing a request
+- `drain`: emitted by polling transports upon a buffer drain
+
+## Tests
+
+`engine.io-client` is used to test
+[engine](http://github.com/socketio/engine.io). Running the `engine.io`
+test suite ensures the client works and vice-versa.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul). You can
+run the tests locally using the following command.
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+Additionally, `engine.io-client` has a standalone test suite you can run
+with `make test` which will run node.js and browser tests. You must have zuul setup with
+a saucelabs account.
+
+## Support
+
+The support channels for `engine.io-client` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Google Groups](http://groups.google.com/group/socket_io)
+  - [Website](http://socket.io)
+
+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:
+
+```bash
+git clone git://github.com/socketio/engine.io-client.git
+```
+
+Then:
+
+```bash
+cd engine.io-client
+npm install
+```
+
+See the `Tests` section above for how to run tests before submitting any patches.

+# engine.io-parser
+
+[![Build Status](https://secure.travis-ci.org/socketio/engine.io-parser.svg)](http://travis-ci.org/socketio/engine.io-parser)
+[![NPM version](https://badge.fury.io/js/engine.io-parser.svg)](http://badge.fury.io/js/engine.io-parser)
+
+This is the JavaScript parser for the engine.io protocol encoding,
+shared by both
+[engine.io-client](https://github.com/socketio/engine.io-client) and
+[engine.io](https://github.com/socketio/engine.io).
+
+## How to use
+
+### Standalone
+
+The parser can encode/decode packets, payloads, and payloads as binary
+with the following methods: `encodePacket`, `decodePacket`, `encodePayload`,
+`decodePayload`, `encodePayloadAsBinary`, `decodePayloadAsBinary`.
+
+The browser-side parser also includes `encodePayloadAsArrayBuffer` and `encodePayloadAsBlob`.
+
+Example:
+
+```js
+var parser = require('engine.io-parser');
+
+var data = new Buffer(5);
+for (var i = 0; i < data.length; i++) { data[i] = i; }
+
+parser.encodePacket({ type: 'message', data: data }, function(encoded) {
+  var decodedData = parser.decodePacket(encoded); // { type: 'message', data: data }
+});
+```
+
+### With browserify
+
+Engine.IO Parser is a commonjs module, which means you can include it by using
+`require` on the browser and package using [browserify](http://browserify.org/):
+
+1. install the parser package
+
+    ```shell
+    npm install engine.io-parser
+    ```
+
+1. write your app code
+
+    ```js
+    var parser = require('engine.io-parser');
+
+    var testBuffer = new Int8Array(10);
+    for (var i = 0; i < testBuffer.length; i++) testBuffer[i] = i;
+
+    var packets = [{ type: 'message', data: testBuffer.buffer }, { type: 'message', data: 'hello' }];
+
+    parser.encodePayload(packets, function(encoded) {
+      parser.decodePayload(encoded,
+        function(packet, index, total) {
+          var isLast = index + 1 == total;
+          if (!isLast) {
+            var buffer = new Int8Array(packet.data); // testBuffer
+          } else {
+            var message = packet.data; // 'hello'
+          }
+        });
+    });
+    ```
+
+1. build your app bundle
+
+    ```bash
+    $ browserify app.js > bundle.js
+    ```
+
+1. include on your page
+
+    ```html
+    <script src="/path/to/bundle.js"></script>
+    ```
+
+## Features
+
+- Runs on browser and node.js seamlessly
+- Runs inside HTML5 WebWorker
+- Can encode and decode packets
+  - Encodes from/to ArrayBuffer or Blob when in browser, and Buffer or ArrayBuffer in Node
+
+## API
+
+Note: `cb(type)` means the type is a callback function that contains a parameter of type `type` when called.
+
+### Node
+
+- `encodePacket`
+    - Encodes a packet.
+    - **Parameters**
+      - `Object`: the packet to encode, has `type` and `data`.
+        - `data`: can be a `String`, `Number`, `Buffer`, `ArrayBuffer`
+      - `Boolean`: optional, binary support
+      - `Function`: callback, returns the encoded packet (`cb(String)`)
+- `decodePacket`
+    - Decodes a packet. Data also available as an ArrayBuffer if requested.
+    - Returns data as `String` or (`Blob` on browser, `ArrayBuffer` on Node)
+    - **Parameters**
+      - `String` | `ArrayBuffer`: the packet to decode, has `type` and `data`
+      - `String`: optional, the binary type
+
+- `encodeBase64Packet`
+    - Encodes a packet with binary data in a base64 string (`String`)
+    - **Parameters**
+      - `Object`: the packet to encode, has `type` and `data`
+      - `Function`: callback, returns the base64 encoded message (`cb(String)`)
+- `decodeBase64Packet`
+    - Decodes a packet encoded in a base64 string.
+    - **Parameters**
+      - `String`: the base64 encoded message
+      - `String`: optional, the binary type
+
+- `encodePayload`
+    - Encodes multiple messages (payload).
+    - If any contents are binary, they will be encoded as base64 strings. Base64
+      encoded strings are marked with a b before the length specifier
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Boolean`: optional, binary support
+      - `Function`: callback, returns the encoded payload (`cb(String)`)
+- `decodePayload`
+    - Decodes data when a payload is maybe expected. Possible binary contents are
+      decoded from their base64 representation.
+    - **Parameters**
+      - `String`: the payload
+      - `String`: optional, the binary type
+      - `Function`: callback, returns (cb(`Object`: packet, `Number`:packet index, `Number`:packet total))
+
+- `encodePayloadAsBinary`
+    - Encodes multiple messages (payload) as binary.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(Buffer)`)
+- `decodePayloadAsBinary`
+    - Decodes data when a payload is maybe expected. Strings are decoded by
+      interpreting each byte as a key code for entries marked to start with 0. See
+      description of encodePayloadAsBinary.
+    - **Parameters**
+      - `Buffer`: the buffer
+      - `String`: optional, the binary type
+      - `Function`: callback, returns the decoded packet (`cb(Object)`)
+
+### Browser
+
+- `encodePayloadAsArrayBuffer`
+    - Encodes multiple messages (payload) as binary.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(ArrayBuffer)`)
+- `encodePayloadAsBlob`
+    - Encodes multiple messages (payload) as blob.
+    - **Parameters**
+      - `Array`: an array of packets
+      - `Function`: callback, returns the encoded payload (`cb(Blob)`)
+
+## Tests
+
+Standalone tests can be run with `make test` which will run both node.js and browser tests.
+
+Browser tests are run using [zuul](https://github.com/defunctzombie/zuul).
+(You must have zuul setup with a saucelabs account.)
+
+You can run the tests locally using the following command:
+
+```
+./node_modules/.bin/zuul --local 8080 -- test/index.js
+```
+
+## Support
+
+The support channels for `engine.io-parser` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Google Groups](http://groups.google.com/group/socket_io)
+  - [Website](http://socket.io)
+
+## Development

+# Engine.IO: the realtime engine
+
+[![Build Status](https://travis-ci.org/socketio/engine.io.svg?branch=master)](http://travis-ci.org/socketio/engine.io)
+[![NPM version](https://badge.fury.io/js/engine.io.svg)](http://badge.fury.io/js/engine.io)
+
+`Engine.IO` is the implementation of transport-based
+cross-browser/cross-device bi-directional communication layer for
+[Socket.IO](http://github.com/socketio/socket.io).
+
+## How to use
+
+### Server
+
+#### (A) Listening on a port
+
+```js
+var engine = require('engine.io');
+var server = engine.listen(80);
+
+server.on('connection', function(socket){
+  socket.send('utf 8 string');
+  socket.send(new Buffer([0, 1, 2, 3, 4, 5])); // binary data
+});
+```
+
+#### (B) Intercepting requests for a http.Server
+
+```js
+var engine = require('engine.io');
+var http = require('http').createServer().listen(3000);
+var server = engine.attach(http);
+
+server.on('connection', function (socket) {
+  socket.on('message', function(data){ });
+  socket.on('close', function(){ });
+});
+```
+
+#### (C) Passing in requests
+
+```js
+var engine = require('engine.io');
+var server = new engine.Server();
+
+server.on('connection', function(socket){
+  socket.send('hi');
+});
+
+// …
+httpServer.on('upgrade', function(req, socket, head){
+  server.handleUpgrade(req, socket, head);
+});
+httpServer.on('request', function(req, res){
+  server.handleRequest(req, res);
+});
+```
+
+### Client
+
+```html
+<script src="/path/to/engine.io.js"></script>
+<script>
+  var socket = new eio.Socket('ws://localhost/');
+  socket.on('open', function(){
+    socket.on('message', function(data){});
+    socket.on('close', function(){});
+  });
+</script>
+```
+
+For more information on the client refer to the
+[engine-client](http://github.com/learnboost/engine.io-client) repository.
+
+## What features does it have?
+
+- **Maximum reliability**. Connections are established even in the presence of:
+  - proxies and load balancers.
+  - personal firewall and antivirus software.
+  - for more information refer to **Goals** and **Architecture** sections
+- **Minimal client size** aided by:
+  - lazy loading of flash transports.
+  - lack of redundant transports.
+- **Scalable**
+  - load balancer friendly
+- **Future proof**
+- **100% Node.JS core style**
+  - No API sugar (left for higher level projects)
+  - Written in readable vanilla JavaScript
+
+## API
+
+### Server
+
+<hr><br>
+
+#### Top-level
+
+These are exposed by `require('engine.io')`:
+
+##### Events
+
+- `flush`
+    - Called when a socket buffer is being flushed.
+    - **Arguments**
+      - `Socket`: socket being flushed
+      - `Array`: write buffer
+- `drain`
+    - Called when a socket buffer is drained
+    - **Arguments**
+      - `Socket`: socket being flushed
+
+##### Properties
+
+- `protocol` _(Number)_: protocol revision number
+- `Server`: Server class constructor
+- `Socket`: Socket class constructor
+- `Transport` _(Function)_: transport constructor
+- `transports` _(Object)_: map of available transports
+
+##### Methods
+
+- `()`
+    - Returns a new `Server` instance. If the first argument is an `http.Server` then the
+      new `Server` instance will be attached to it. Otherwise, the arguments are passed
+      directly to the `Server` constructor.
+    - **Parameters**
+      - `http.Server`: optional, server to attach to.
+      - `Object`: optional, options object (see `Server#constructor` api docs below)
+
+  The following are identical ways to instantiate a server and then attach it.
+  ```js
+  var httpServer; // previously created with `http.createServer();` from node.js api.
+
+  // create a server first, and then attach
+  var eioServer = require('engine.io').Server();
+  eioServer.attach(httpServer);
+
+  // or call the module as a function to get `Server`
+  var eioServer = require('engine.io')();
+  eioServer.attach(httpServer);
+
+  // immediately attach
+  var eioServer = require('engine.io')(httpServer);
+  ```
+
+- `listen`
+    - Creates an `http.Server` which listens on the given port and attaches WS
+      to it. It returns `501 Not Implemented` for regular http requests.
+    - **Parameters**
+      - `Number`: port to listen on.
+      - `Object`: optional, options object
+      - `Function`: callback for `listen`.
+    - **Options**
+      - All options from `Server.attach` method, documented below.
+      - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+    - **Returns** `Server`
+- `attach`
+    - Captures `upgrade` requests for a `http.Server`. In other words, makes
+      a regular http.Server WebSocket-compatible.
+    - **Parameters**
+      - `http.Server`: server to attach to.
+      - `Object`: optional, options object
+    - **Options**
+      - All options from `Server.attach` method, documented below.
+      - **Additionally** See Server `constructor` below for options you can pass for creating the new Server
+    - **Returns** `Server` a new Server instance.
+

+
+#### Server
+
+The main server/manager. _Inherits from EventEmitter_.
+
+##### Events
+
+- `connection`
+    - Fired when a new connection is established.
+    - **Arguments**
+      - `Socket`: a Socket object
+
+##### Properties
+
+**Important**: if you plan to use Engine.IO in a scalable way, please
+keep in mind the properties below will only reflect the clients connected
+to a single process.
+
+- `clients` _(Object)_: hash of connected clients by id.
+- `clientsCount` _(Number)_: number of connected clients.
+
+##### Methods
+
+- **constructor**
+    - Initializes the server
+    - **Parameters**
+      - `Object`: optional, options object
+    - **Options**
+      - `pingTimeout` (`Number`): how many ms without a pong packet to
+        consider the connection closed (`60000`)
+      - `pingInterval` (`Number`): how many ms before sending a new ping
+        packet (`25000`)
+      - `upgradeTimeout` (`Number`): how many ms before an uncompleted transport upgrade is cancelled (`10000`)
+      - `maxHttpBufferSize` (`Number`): how many bytes or characters a message
+        can be, before closing the session (to avoid DoS). Default
+        value is `10E7`.
+      - `allowRequest` (`Function`): A function that receives a given handshake
+        or upgrade request as its first parameter, and can decide whether to
+        continue or not. The second argument is a function that needs to be
+        called with the decided information: `fn(err, success)`, where
+        `success` is a boolean value where false means that the request is
+        rejected, and err is an error code.
+      - `transports` (`<Array> String`): transports to allow connections
+        to (`['polling', 'websocket']`)
+      - `allowUpgrades` (`Boolean`): whether to allow transport upgrades
+        (`true`)
+      - `perMessageDeflate` (`Object|Boolean`): parameters of the WebSocket permessage-deflate extension
+        (see [ws module](https://github.com/einaros/ws) api docs). Set to `false` to disable. (`true`)
+        - `threshold` (`Number`): data is compressed only if the byte size is above this value (`1024`)
+      - `httpCompression` (`Object|Boolean`): parameters of the http compression for the polling transports
+        (see [zlib](http://nodejs.org/api/zlib.html#zlib_options) api docs). Set to `false` to disable. (`true`)
+        - `threshold` (`Number`): data is compressed only if the byte size is above this value (`1024`)
+      - `cookie` (`String|Boolean`): name of the HTTP cookie that

+        headers. Set to `false` to not send one. (`io`)
+      - `cookiePath` (`String|Boolean`): path of the above `cookie`
+        option. If false, no path will be sent, which means browsers will only send the cookie on the engine.io attached path (`/engine.io`).
+        Set false to not save io cookie on all requests. (`/`)
+      - `cookieHttpOnly` (`Boolean`): If `true` HttpOnly io cookie cannot be accessed by client-side APIs, such as JavaScript. (`true`) _This option has no effect if `cookie` or `cookiePath` is set to `false`._
+      - `wsEngine` (`String`): what WebSocket server implementation to use. Specified module must conform to the `ws` interface (see [ws module api docs](https://github.com/websockets/ws/blob/master/doc/ws.md)).

+### Client
+
+<hr><br>
+
+Exposed in the `eio` global namespace (in the browser), or by
+`require('engine.io-client')` (in Node.JS).
+
+For the client API refer to the
+[engine-client](http://github.com/learnboost/engine.io-client) repository.
+
+## Debug / logging
+
+Engine.IO is powered by [debug](http://github.com/visionmedia/debug).
+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Engine.IO's debugging scopes you can use:
+
+```
+DEBUG=engine* node myapp
+```
+
+## Transports
+
+- `polling`: XHR / JSONP polling transport.
+- `websocket`: WebSocket transport.
+
+## Plugins
+
+- [engine.io-conflation](https://github.com/EugenDueck/engine.io-conflation): Makes **conflation and aggregation** of messages straightforward.
+
+## Support
+
+The support channels for `engine.io` are the same as `socket.io`:
+  - irc.freenode.net **#socket.io**
+  - [Google Groups](http://groups.google.com/group/socket_io)
+  - [Website](http://socket.io)
+
+## Development
+
+To contribute patches, run tests or benchmarks, make sure to clone the
+repository:
+
+```
+git clone git://github.com/LearnBoost/engine.io.git
+```
+
+Then:
+
+```
+cd engine.io
+npm install
+```
+
+## Tests
+
+Tests run with `make test`. It runs the server tests that are aided by
+the usage of `engine.io-client`.
+
+Make sure `npm install` is run first.
+
+## Goals
+
+The main goal of `Engine` is ensuring the most reliable realtime communication.
+Unlike the previous Socket.IO core, it always establishes a long-polling
+connection first, then tries to upgrade to better transports that are "tested" on
+the side.
+
+During the lifetime of the Socket.IO projects, we've found countless drawbacks
+to relying on `HTML5 WebSocket` or `Flash Socket` as the first connection
+mechanisms.
+
+Both are clearly the _right way_ of establishing a bidirectional communication,
+with HTML5 WebSocket being the way of the future. However, to answer most business
+needs, alternative traditional HTTP 1.1 mechanisms are just as good as delivering
+the same solution.
+
+WebSocket based connections have two fundamental benefits:
+
+1. **Better server performance**
+  - _A: Load balancers_<br>
+      Load balancing a long polling connection poses a serious architectural nightmare
+      since requests can come from any number of open sockets by the user agent, but
+      they all need to be routed to the process and computer that owns the `Engine`
+      connection. This negatively impacts RAM and CPU usage.
+  - _B: Network traffic_<br>
+      WebSocket is designed around the premise that each message frame has to be
+      surrounded by the least amount of data. In HTTP 1.1 transports, each message
+      frame is surrounded by HTTP headers and chunked encoding frames. If you try to
+      send the message _"Hello world"_ with xhr-polling, the message ultimately
+      becomes larger than if you were to send it with WebSocket.
+  - _C: Lightweight parser_<br>
+      As an effect of **B**, the server has to do a lot more work to parse the network
+      data and figure out the message when traditional HTTP requests are used
+      (as in long polling). This means that another advantage of WebSocket is
+      less server CPU usage.
+
+2. **Better user experience**
+
+    Due to the reasons stated in point **1**, the most important effect of being able
+    to establish a WebSocket connection is raw data transfer speed, which translates
+    in _some_ cases in better user experience.
+
+    Applications with heavy realtime interaction (such as games) will benefit greatly,
+    whereas applications like realtime chat (Gmail/Facebook), newsfeeds (Facebook) or
+    timelines (Twitter) will have negligible user experience improvements.
+
+Having said this, attempting to establish a WebSocket connection directly so far has
+proven problematic:
+
+1. **Proxies**<br>
+    Many corporate proxies block WebSocket traffic.
+
+2. **Personal firewall and antivirus software**<br>
+    As a result of our research, we've found that at least 3 personal security
+    applications block WebSocket traffic.
+
+3. **Cloud application platforms**<br>
+    Platforms like Heroku or No.de have had trouble keeping up with the fast-paced
+    nature of the evolution of the WebSocket protocol. Applications therefore end up
+    inevitably using long polling, but the seamless installation experience of
+    Socket.IO we strive for (_"require() it and it just works"_) disappears.
+
+Some of these problems have solutions. In the case of proxies and personal programs,
+however, the solutions many times involve upgrading software. Experience has shown
+that relying on client software upgrades to deliver a business solution is
+fruitless: the very existence of this project has to do with a fragmented panorama
+of user agent distribution, with clients connecting with latest versions of the most
+modern user agents (Chrome, Firefox and Safari), but others with versions as low as
+IE 5.5.
+
+From the user perspective, an unsuccessful WebSocket connection can translate in
+up to at least 10 seconds of waiting for the realtime application to begin
+exchanging data. This **perceptively** hurts user experience.
+
+To summarize, **Engine** focuses on reliability and user experience first, marginal
+potential UX improvements and increased server performance second. `Engine` is the
+result of all the lessons learned with WebSocket in the wild.
+
+## Architecture
+
+The main premise of `Engine`, and the core of its existence, is the ability to
+swap transports on the fly. A connection starts as xhr-polling, but it can
+switch to WebSocket.
+
+The central problem this poses is: how do we switch transports without losing
+messages?
+
+`Engine` only switches from polling to another transport in between polling
+cycles. Since the server closes the connection after a certain timeout when
+there's no activity, and the polling transport implementation buffers messages
+in between connections, this ensures no message loss and optimal performance.
+
+Another benefit of this design is that we workaround almost all the limitations
+of **Flash Socket**, such as slow connection times, increased file size (we can
+safely lazy load it without hurting user experience), etc.
+
+## FAQ
+
+### Can I use engine without Socket.IO ?
+
+Absolutely. Although the recommended framework for building realtime applications
+is Socket.IO, since it provides fundamental features for real-world applications
+such as multiplexing, reconnection support, etc.
+
+`Engine` is to Socket.IO what Connect is to Express. An essential piece for building
+realtime frameworks, but something you _probably_ won't be using for building
+actual applications.
+
+### Does the server serve the client?
+
+No. The main reason is that `Engine` is meant to be bundled with frameworks.
+Socket.IO includes `Engine`, therefore serving two clients is not necessary. If
+you use Socket.IO, including
+
+```html
+<script src="/socket.io/socket.io.js">
+```
+
+has you covered.
+
+### Can I implement `Engine` in other languages?
+
+Absolutely. The [engine.io-protocol](https://github.com/LearnBoost/engine.io-protocol)
+repository contains the most up to date description of the specification
+at all times, and the parser implementation in JavaScript.

+
+Higher level content negotiation based on [negotiator](https://www.npmjs.com/package/negotiator). Extracted from [koa](https://www.npmjs.com/package/koa) for general use.
+
+In addition to negotiator, it allows:
+
+- Allows types as an array or arguments list, ie `(['text/html', 'application/json'])` as well as `('text/html', 'application/json')`.
+- Allows type shorthands such as `json`.
+- Returns `false` when no types match
+- Treats non-existent headers as `*`
+
+## Installation
+
+```sh
+npm install accepts
+```
+
+## API
+
+```js
+var accepts = require('accepts')
+```
+
+### accepts(req)
+
+Create a new `Accepts` object for the given `req`.
+
+#### .charset(charsets)
+
+Return the first accepted charset. If nothing in `charsets` is accepted,
+then `false` is returned.
+
+#### .charsets()
+
+Return the charsets that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .encoding(encodings)
+
+Return the first accepted encoding. If nothing in `encodings` is accepted,
+then `false` is returned.
+
+#### .encodings()
+
+Return the encodings that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .language(languages)
+
+Return the first accepted language. If nothing in `languages` is accepted,
+then `false` is returned.
+
+#### .languages()
+
+Return the languages that the request accepts, in the order of the client's
+preference (most preferred first).
+
+#### .type(types)
+
+Return the first accepted type (and it is returned as the same text as what
+appears in the `types` array). If nothing in `types` is accepted, then `false`
+is returned.
+
+The `types` array can contain full MIME types or file extensions. Any value
+that is not a full MIME types is passed to `require('mime-types').lookup`.
+
+#### .types()
+
+Return the types that the request accepts, in the order of the client's
+preference (most preferred first).
+
+## Examples
+
+### Simple type negotiation
+
+This simple example shows how to use `accepts` to return a different typed
+respond body based on what the client wants to accept. The server lists it's
+preferences in order and will get back the best match between the client and
+server.
+
+```js
+var accepts = require('accepts')
+var http = require('http')
+
+function app(req, res) {
+  var accept = accepts(req)
+
+  // the order of this list is significant; should be server preferred order
+  switch(accept.type(['json', 'html'])) {
+    case 'json':
+      res.setHeader('Content-Type', 'application/json')
+      res.write('{"hello":"world!"}')
+      break
+    case 'html':
+      res.setHeader('Content-Type', 'text/html')
+      res.write('<b>hello, world!</b>')
+      break
+    default:
+      // the fallback is text/plain, so no need to specify it above
+      res.setHeader('Content-Type', 'text/plain')
+      res.write('hello, world!')
+      break
+  }
+
+  res.end()
+}
+
+http.createServer(app).listen(3000)
+```
+
+You can test this out with the cURL program:
+```sh
+curl -I -H'Accept: text/html' http://localhost:3000/
+```

+
+Create simple HTTP ETags
+
+This module generates HTTP ETags (as defined in RFC 7232) for use in
+HTTP responses.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install etag
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var etag = require('etag')
+```
+
+### etag(entity, [options])
+
+Generate a strong ETag for the given entity. This should be the complete
+body of the entity. Strings, `Buffer`s, and `fs.Stats` are accepted. By
+default, a strong ETag is generated except for `fs.Stats`, which will
+generate a weak ETag (this can be overwritten by `options.weak`).
+
+<!-- eslint-disable no-undef -->
+
+```js
+res.setHeader('ETag', etag(body))
+```
+
+#### Options
+
+`etag` accepts these properties in the options object.
+
+##### weak
+
+Specifies if the generated ETag will include the weak validator mark (that
+is, the leading `W/`). The actual entity tag is the same. The default value
+is `false`, unless the `entity` is `fs.Stats`, in which case it is `true`.
+
+## Testing
+
+```sh
+$ npm test

+
+### Security Issues
+
+If you discover a security vulnerability in Express, please see [Security Policies and Procedures](Security.md).
+
+## Quick Start
+
+  The quickest way to get started with express is to utilize the executable [`express(1)`](https://github.com/expressjs/generator) to generate an application as shown below:
+
+  Install the executable. The executable's major version will match Express's:
+
+```bash
+$ npm install -g express-generator@4
+```
+
+  Create the app:
+
+```bash
+$ express /tmp/foo && cd /tmp/foo
+```
+
+  Install dependencies:
+
+```bash
+$ npm install
+```
+
+  Start the server:
+
+```bash
+$ npm start
+```
+
+## Philosophy
+
+  The Express philosophy is to provide small, robust tooling for HTTP servers, making
+  it a great solution for single page applications, web sites, hybrids, or public
+  HTTP APIs.
+
+  Express does not force you to use any specific ORM or template engine. With support for over
+  14 template engines via [Consolidate.js](https://github.com/tj/consolidate.js),
+  you can quickly craft your perfect framework.
+
+## Examples
+
+  To view the examples, clone the Express repo and install the dependencies:
+
+```bash
+$ git clone git://github.com/expressjs/express.git --depth 1
+$ cd express
+$ npm install
+```
+
+  Then run whichever example you want:
+
+```bash
+$ node examples/content-negotiation
+```
+
+## Tests
+
+  To run the test suite, first install the dependencies, then run `npm test`:
+
+```bash
+$ npm install
+$ npm test
+```
+

+
+Node.js function to invoke as the final step to respond to HTTP request.
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install finalhandler
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var finalhandler = require('finalhandler')
+```
+
+### finalhandler(req, res, [options])
+
+Returns function to be invoked as the final step for the given `req` and `res`.
+This function is to be invoked as `fn(err)`. If `err` is falsy, the handler will
+write out a 404 response to the `res`. If it is truthy, an error response will
+be written out to the `res`.
+
+When an error is written, the following information is added to the response:
+
+  * The `res.statusCode` is set from `err.status` (or `err.statusCode`). If
+    this value is outside the 4xx or 5xx range, it will be set to 500.
+  * The `res.statusMessage` is set according to the status code.
+  * The body will be the HTML of the status code message if `env` is
+    `'production'`, otherwise will be `err.stack`.
+  * Any headers specified in an `err.headers` object.
+
+The final handler will also unpipe anything from `req` when it is invoked.
+
+#### options.env
+
+By default, the environment is determined by `NODE_ENV` variable, but it can be
+overridden by this option.
+
+#### options.onerror
+
+Provide a function to be called with the `err` when it exists. Can be used for
+writing errors to a central location without excessive function generation. Called
+as `onerror(err, req, res)`.
+
+## Examples
+
+### always 404
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+  done()
+})
+
+server.listen(3000)
+```
+
+### perform simple action
+
+```js
+var finalhandler = require('finalhandler')
+var fs = require('fs')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+
+  fs.readFile('index.html', function (err, buf) {
+    if (err) return done(err)
+    res.setHeader('Content-Type', 'text/html')
+    res.end(buf)
+  })
+})
+
+server.listen(3000)
+```
+
+### use with middleware-style functions
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+var serve = serveStatic('public')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res)
+  serve(req, res, done)
+})
+
+server.listen(3000)
+```
+
+### keep log of all errors
+
+```js
+var finalhandler = require('finalhandler')
+var fs = require('fs')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  var done = finalhandler(req, res, {onerror: logerror})
+
+  fs.readFile('index.html', function (err, buf) {
+    if (err) return done(err)
+    res.setHeader('Content-Type', 'text/html')
+    res.end(buf)
+  })
+})
+
+server.listen(3000)
+
+function logerror (err) {
+  console.error(err.stack || err.toString())
+}
+```

+Parse HTTP X-Forwarded-For header
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install forwarded
+```
+
+## API
+
+```js
+var forwarded = require('forwarded')
+```
+
+### forwarded(req)
+
+```js
+var addresses = forwarded(req)
+```
+
+Parse the `X-Forwarded-For` header from the request. Returns an array
+of the addresses, including the socket address for the `req`, in reverse
+order (i.e. index `0` is the socket address and the last index is the
+furthest address, typically the end-user).
+
+## Testing
+
+```sh
+$ npm test
+```

+
+HTTP response freshness testing
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```
+$ npm install fresh
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var fresh = require('fresh')
+```
+
+### fresh(reqHeaders, resHeaders)
+
+Check freshness of the response using request and response headers.
+
+When the response is still "fresh" in the client's cache `true` is
+returned, otherwise `false` is returned to indicate that the client
+cache is now stale and the full response should be sent.
+
+When a client sends the `Cache-Control: no-cache` request header to
+indicate an end-to-end reload request, this module will return `false`
+to make handling these requests transparent.
+
+## Known Issues
+
+This module is designed to only follow the HTTP specifications, not
+to work-around all kinda of client bugs (especially since this module
+typically does not recieve enough information to understand what the
+client actually is).
+
+There is a known issue that in certain versions of Safari, Safari
+will incorrectly make a request that allows this module to validate
+freshness of the resource even when Safari does not have a
+representation of the resource in the cache. The module
+[jumanji](https://www.npmjs.com/package/jumanji) can be used in
+an Express application to work-around this issue and also provides
+links to further reading on this Safari bug.
+
+## Example
+
+### API usage
+
+<!-- eslint-disable no-redeclare, no-undef -->
+
+```js
+var reqHeaders = { 'if-none-match': '"foo"' }
+var resHeaders = { 'etag': '"bar"' }
+fresh(reqHeaders, resHeaders)
+// => false
+
+var reqHeaders = { 'if-none-match': '"foo"' }
+var resHeaders = { 'etag': '"foo"' }
+fresh(reqHeaders, resHeaders)
+// => true
+```
+
+### Using with Node.js http server
+
+```js
+var fresh = require('fresh')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  // perform server logic
+  // ... including adding ETag / Last-Modified response headers
+
+  if (isFresh(req, res)) {
+    // client has a fresh copy of resource
+    res.statusCode = 304
+    res.end()
+    return
+  }
+
+  // send the resource
+  res.statusCode = 200
+  res.end('hello, world!')
+})
+
+function isFresh (req, res) {
+  return fresh(req.headers, {
+    'etag': res.getHeader('ETag'),
+    'last-modified': res.getHeader('Last-Modified')
+  })
+}
+
+server.listen(3000)
+```

+
+Create HTTP errors for Express, Koa, Connect, etc. with ease.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install http-errors
+```
+
+## Example
+
+```js
+var createError = require('http-errors')
+var express = require('express')
+var app = express()
+
+app.use(function (req, res, next) {
+  if (!req.user) return next(createError(401, 'Please login to view this page.'))
+  next()
+})
+```
+
+## API
+
+This is the current API, currently extracted from Koa and subject to change.
+
+All errors inherit from JavaScript `Error` and the exported `createError.HttpError`.
+
+### Error Properties
+
+- `expose` - can be used to signal if `message` should be sent to the client,
+  defaulting to `false` when `status` >= 500
+- `headers` - can be an object of header names to values to be sent to the
+  client, defaulting to `undefined`. When defined, the key names should all
+  be lower-cased
+- `message` - the traditional error message, which should be kept short and all
+  single line
+- `status` - the status code of the error, mirroring `statusCode` for general
+  compatibility
+- `statusCode` - the status code of the error, defaulting to `500`
+
+### createError([status], [message], [properties])
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var err = createError(404, 'This video does not exist!')
+```
+
+- `status: 500` - the status code as a number
+- `message` - the message of the error, defaulting to node's text for that status code.
+- `properties` - custom properties to attach to the object
+
+### new createError\[code || name\](\[msg]\))
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var err = new createError.NotFound()
+```
+
+- `code` - the status code as a number
+- `name` - the name of the error as a "bumpy case", i.e. `NotFound` or `InternalServerError`.
+
+#### List of all constructors
+
+|Status Code|Constructor Name             |

+## Pure JS character encoding conversion [![Build Status](https://travis-ci.org/ashtuchkin/iconv-lite.svg?branch=master)](https://travis-ci.org/ashtuchkin/iconv-lite)
+
+ * Doesn't need native code compilation. Works on Windows and in sandboxed environments like [Cloud9](http://c9.io).
+ * Used in popular projects like [Express.js (body_parser)](https://github.com/expressjs/body-parser), 
+   [Grunt](http://gruntjs.com/), [Nodemailer](http://www.nodemailer.com/), [Yeoman](http://yeoman.io/) and others.
+ * Faster than [node-iconv](https://github.com/bnoordhuis/node-iconv) (see below for performance comparison).
+ * Intuitive encode/decode API
+ * Streaming support for Node v0.10+
+ * [Deprecated] Can extend Node.js primitives (buffers, streams) to support all iconv-lite encodings.
+ * In-browser usage via [Browserify](https://github.com/substack/node-browserify) (~180k gzip compressed with Buffer shim included).
+ * Typescript [type definition file](https://github.com/ashtuchkin/iconv-lite/blob/master/lib/index.d.ts) included.
+ * React Native is supported (need to explicitly `npm install` two more modules: `buffer` and `stream`).
+ * License: MIT.
+
+[![NPM Stats](https://nodei.co/npm/iconv-lite.png?downloads=true&downloadRank=true)](https://npmjs.org/packages/iconv-lite/)
+
+## Usage
+### Basic API
+```javascript
+var iconv = require('iconv-lite');
+
+// Convert from an encoded buffer to js string.
+str = iconv.decode(new Buffer([0x68, 0x65, 0x6c, 0x6c, 0x6f]), 'win1251');
+
+// Convert from js string to an encoded buffer.
+buf = iconv.encode("Sample input string", 'win1251');
+
+// Check if encoding is supported
+iconv.encodingExists("us-ascii")
+```
+
+### Streaming API (Node v0.10+)
+```javascript
+
+// Decode stream (from binary stream to js strings)
+http.createServer(function(req, res) {
+    var converterStream = iconv.decodeStream('win1251');
+    req.pipe(converterStream);
+
+    converterStream.on('data', function(str) {
+        console.log(str); // Do something with decoded strings, chunk-by-chunk.
+    });
+});
+
+// Convert encoding streaming example
+fs.createReadStream('file-in-win1251.txt')
+    .pipe(iconv.decodeStream('win1251'))
+    .pipe(iconv.encodeStream('ucs2'))
+    .pipe(fs.createWriteStream('file-in-ucs2.txt'));
+
+// Sugar: all encode/decode streams have .collect(cb) method to accumulate data.
+http.createServer(function(req, res) {
+    req.pipe(iconv.decodeStream('win1251')).collect(function(err, body) {
+        assert(typeof body == 'string');
+        console.log(body); // full request body string
+    });
+});
+```
+
+### [Deprecated] Extend Node.js own encodings
+> NOTE: This doesn't work on latest Node versions. See [details](https://github.com/ashtuchkin/iconv-lite/wiki/Node-v4-compatibility).
+
+```javascript
+// After this call all Node basic primitives will understand iconv-lite encodings.
+iconv.extendNodeEncodings();
+
+// Examples:
+buf = new Buffer(str, 'win1251');
+buf.write(str, 'gbk');
+str = buf.toString('latin1');
+assert(Buffer.isEncoding('iso-8859-15'));
+Buffer.byteLength(str, 'us-ascii');
+
+http.createServer(function(req, res) {
+    req.setEncoding('big5');
+    req.collect(function(err, body) {
+        console.log(body);
+    });
+});
+
+fs.createReadStream("file.txt", "shift_jis");
+
+// External modules are also supported (if they use Node primitives, which they probably do).
+request = require('request');
+request({
+    url: "http://github.com/", 
+    encoding: "cp932"
+});
+
+// To remove extensions
+iconv.undoExtendNodeEncodings();
+```
+
+## Supported encodings
+
+ *  All node.js native encodings: utf8, ucs2 / utf16-le, ascii, binary, base64, hex.
+ *  Additional unicode encodings: utf16, utf16-be, utf-7, utf-7-imap.
+ *  All widespread singlebyte encodings: Windows 125x family, ISO-8859 family, 
+    IBM/DOS codepages, Macintosh family, KOI8 family, all others supported by iconv library. 
+    Aliases like 'latin1', 'us-ascii' also supported.
+ *  All widespread multibyte encodings: CP932, CP936, CP949, CP950, GB2312, GBK, GB18030, Big5, Shift_JIS, EUC-JP.
+
+See [all supported encodings on wiki](https://github.com/ashtuchkin/iconv-lite/wiki/Supported-Encodings).
+
+Most singlebyte encodings are generated automatically from [node-iconv](https://github.com/bnoordhuis/node-iconv). Thank you Ben Noordhuis and libiconv authors!
+
+Multibyte encodings are generated from [Unicode.org mappings](http://www.unicode.org/Public/MAPPINGS/) and [WHATWG Encoding Standard mappings](http://encoding.spec.whatwg.org/). Thank you, respective authors!
+
+
+## Encoding/decoding speed
+
+Comparison with node-iconv module (1000x256kb, on MacBook Pro, Core i5/2.6 GHz, Node v0.12.0). 
+Note: your results may vary, so please always check on your hardware.
+
+    operation             iconv@2.1.4   iconv-lite@0.4.7
+    ----------------------------------------------------------
+    encode('win1251')     ~96 Mb/s      ~320 Mb/s
+    decode('win1251')     ~95 Mb/s      ~246 Mb/s
+
+## BOM handling
+
+ * Decoding: BOM is stripped by default, unless overridden by passing `stripBOM: false` in options
+   (f.ex. `iconv.decode(buf, enc, {stripBOM: false})`).
+   A callback might also be given as a `stripBOM` parameter - it'll be called if BOM character was actually found.
+ * If you want to detect UTF-8 BOM when decoding other encodings, use [node-autodetect-decoder-stream](https://github.com/danielgindi/node-autodetect-decoder-stream) module.
+ * Encoding: No BOM added, unless overridden by `addBOM: true` option.
+
+## UTF-16 Encodings
+
+This library supports UTF-16LE, UTF-16BE and UTF-16 encodings. First two are straightforward, but UTF-16 is trying to be
+smart about endianness in the following ways:
+ * Decoding: uses BOM and 'spaces heuristic' to determine input endianness. Default is UTF-16LE, but can be 
+   overridden with `defaultEncoding: 'utf-16be'` option. Strips BOM unless `stripBOM: false`.
+ * Encoding: uses UTF-16LE and writes BOM by default. Use `addBOM: false` to override.
+
+## Other notes
+
+When decoding, be sure to supply a Buffer to decode() method, otherwise [bad things usually happen](https://github.com/ashtuchkin/iconv-lite/wiki/Use-Buffers-when-decoding).  
+Untranslatable characters are set to � or ?. No transliteration is currently supported.  
+Node versions 0.10.31 and 0.11.13 are buggy, don't use them (see #65, #77).  
+
+## Testing
+
+```bash
+$ git clone git@github.com:ashtuchkin/iconv-lite.git
+$ cd iconv-lite
+$ npm install
+$ npm test
+    
+$ # To view performance:
+$ node test/performance.js

+Browser-friendly inheritance fully compatible with standard node.js
+[inherits](http://nodejs.org/api/util.html#util_util_inherits_constructor_superconstructor).
+
+This package exports standard `inherits` from node.js `util` module in
+node environment, but also provides alternative browser-friendly
+implementation through [browser
+field](https://gist.github.com/shtylman/4339901). Alternative
+implementation is a literal copy of standard one located in standalone
+module to avoid requiring of `util`. It also has a shim for old
+browsers with no `Object.create` support.
+
+While keeping you sure you are using standard `inherits`
+implementation in node.js environment, it allows bundlers such as
+[browserify](https://github.com/substack/node-browserify) to not
+include full `util` package to your client code if all you need is
+just `inherits` function. It worth, because browser shim for `util`
+package is large and `inherits` is often the single function you need
+from it.
+
+It's recommended to use this package instead of
+`require('util').inherits` for any code that has chances to be used
+not only in node.js but in browser too.
+
+## usage
+
+```js
+var inherits = require('inherits');
+// then use exactly as the standard one
+```
+
+## note on version ~1.0
+
+Version ~1.0 had completely different motivation and is not compatible
+neither with 2.0 nor with standard node.js `inherits`.
+
+If you are using version ~1.0 and planning to switch to ~2.0, be
+careful:
+
+* new version uses `super_` instead of `super` for referencing
+  superclass
+* new version overwrites current prototype while old one preserves any
+  existing fields on it

+# ipaddr.js — an IPv6 and IPv4 address manipulation library [![Build Status](https://travis-ci.org/whitequark/ipaddr.js.svg)](https://travis-ci.org/whitequark/ipaddr.js)
+
+ipaddr.js is a small (1.9K minified and gzipped) library for manipulating
+IP addresses in JavaScript environments. It runs on both CommonJS runtimes
+(e.g. [nodejs]) and in a web browser.
+
+ipaddr.js allows you to verify and parse string representation of an IP
+address, match it against a CIDR range or range list, determine if it falls
+into some reserved ranges (examples include loopback and private ranges),
+and convert between IPv4 and IPv4-mapped IPv6 addresses.
+
+[nodejs]: http://nodejs.org
+
+## Installation
+
+`npm install ipaddr.js`
+
+or
+
+`bower install ipaddr.js`
+
+## API
+
+ipaddr.js defines one object in the global scope: `ipaddr`. In CommonJS,
+it is exported from the module:
+
+```js
+var ipaddr = require('ipaddr.js');
+```
+
+The API consists of several global methods and two classes: ipaddr.IPv6 and ipaddr.IPv4.
+
+### Global methods
+
+There are three global methods defined: `ipaddr.isValid`, `ipaddr.parse` and
+`ipaddr.process`. All of them receive a string as a single parameter.
+
+The `ipaddr.isValid` method returns `true` if the address is a valid IPv4 or
+IPv6 address, and `false` otherwise. It does not throw any exceptions.
+
+The `ipaddr.parse` method returns an object representing the IP address,
+or throws an `Error` if the passed string is not a valid representation of an
+IP address.
+
+The `ipaddr.process` method works just like the `ipaddr.parse` one, but it
+automatically converts IPv4-mapped IPv6 addresses to their IPv4 counterparts
+before returning. It is useful when you have a Node.js instance listening
+on an IPv6 socket, and the `net.ivp6.bindv6only` sysctl parameter (or its
+equivalent on non-Linux OS) is set to 0. In this case, you can accept IPv4
+connections on your IPv6-only socket, but the remote address will be mangled.
+Use `ipaddr.process` method to automatically demangle it.
+
+### Object representation
+
+Parsing methods return an object which descends from `ipaddr.IPv6` or
+`ipaddr.IPv4`. These objects share some properties, but most of them differ.
+
+#### Shared properties
+
+One can determine the type of address by calling `addr.kind()`. It will return
+either `"ipv6"` or `"ipv4"`.
+
+An address can be converted back to its string representation with `addr.toString()`.
+Note that this method:
+ * does not return the original string used to create the object (in fact, there is
+   no way of getting that string)
+ * returns a compact representation (when it is applicable)
+
+A `match(range, bits)` method can be used to check if the address falls into a
+certain CIDR range.
+Note that an address can be (obviously) matched only against an address of the same type.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:db8:1234::1");
+var range = ipaddr.parse("2001:db8::");
+
+addr.match(range, 32); // => true
+```
+
+Alternatively, `match` can also be called as `match([range, bits])`. In this way,
+it can be used together with the `parseCIDR(string)` method, which parses an IP
+address together with a CIDR range.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:db8:1234::1");
+
+addr.match(ipaddr.parseCIDR("2001:db8::/32")); // => true
+```
+
+A `range()` method returns one of predefined names for several special ranges defined
+by IP protocols. The exact names (and their respective CIDR ranges) can be looked up
+in the source: [IPv6 ranges] and [IPv4 ranges]. Some common ones include `"unicast"`
+(the default one) and `"reserved"`.
+
+You can match against your own range list by using
+`ipaddr.subnetMatch(address, rangeList, defaultName)` method. It can work with a mix of IPv6 or IPv4 addresses, and accepts a name-to-subnet map as the range list. For example:
+
+```js
+var rangeList = {
+  documentationOnly: [ ipaddr.parse('2001:db8::'), 32 ],
+  tunnelProviders: [
+    [ ipaddr.parse('2001:470::'), 32 ], // he.net
+    [ ipaddr.parse('2001:5c0::'), 32 ]  // freenet6
+  ]
+};
+ipaddr.subnetMatch(ipaddr.parse('2001:470:8:66::1'), rangeList, 'unknown'); // => "tunnelProviders"
+```
+
+The addresses can be converted to their byte representation with `toByteArray()`.
+(Actually, JavaScript mostly does not know about byte buffers. They are emulated with
+arrays of numbers, each in range of 0..255.)
+
+```js
+var bytes = ipaddr.parse('2a00:1450:8007::68').toByteArray(); // ipv6.google.com
+bytes // => [42, 0x00, 0x14, 0x50, 0x80, 0x07, 0x00, <zeroes...>, 0x00, 0x68 ]
+```
+
+The `ipaddr.IPv4` and `ipaddr.IPv6` objects have some methods defined, too. All of them
+have the same interface for both protocols, and are similar to global methods.
+
+`ipaddr.IPvX.isValid(string)` can be used to check if the string is a valid address
+for particular protocol, and `ipaddr.IPvX.parse(string)` is the error-throwing parser.
+
+`ipaddr.IPvX.isValid(string)` uses the same format for parsing as the POSIX `inet_ntoa` function, which accepts unusual formats like `0xc0.168.1.1` or `0x10000000`. The function `ipaddr.IPv4.isValidFourPartDecimal(string)` validates the IPv4 address and also ensures that it is written in four-part decimal format.
+
+[IPv6 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L186
+[IPv4 ranges]: https://github.com/whitequark/ipaddr.js/blob/master/src/ipaddr.coffee#L71
+
+#### IPv6 properties
+
+Sometimes you will want to convert IPv6 not to a compact string representation (with
+the `::` substitution); the `toNormalizedString()` method will return an address where
+all zeroes are explicit.
+
+For example:
+
+```js
+var addr = ipaddr.parse("2001:0db8::0001");
+addr.toString(); // => "2001:db8::1"
+addr.toNormalizedString(); // => "2001:db8:0:0:0:0:0:1"
+```
+
+The `isIPv4MappedAddress()` method will return `true` if this address is an IPv4-mapped
+one, and `toIPv4Address()` will return an IPv4 object address.
+
+To access the underlying binary representation of the address, use `addr.parts`.
+
+```js
+var addr = ipaddr.parse("2001:db8:10::1234:DEAD");
+addr.parts // => [0x2001, 0xdb8, 0x10, 0, 0, 0, 0x1234, 0xdead]
+```
+
+A IPv6 zone index can be accessed via `addr.zoneId`:
+
+```js
+var addr = ipaddr.parse("2001:db8::%eth0");
+addr.zoneId // => 'eth0'
+```
+
+#### IPv4 properties
+
+`toIPv4MappedAddress()` will return a corresponding IPv4-mapped IPv6 address.
+
+To access the underlying representation of the address, use `addr.octets`.
+
+```js
+var addr = ipaddr.parse("192.168.1.1");
+addr.octets // => [192, 168, 1, 1]
+```
+
+`prefixLengthFromSubnetMask()` will return a CIDR prefix length for a valid IPv4 netmask or
+false if the netmask is not valid.
+
+```js
+ipaddr.IPv4.parse('255.255.255.240').prefixLengthFromSubnetMask() == 28
+ipaddr.IPv4.parse('255.192.164.0').prefixLengthFromSubnetMask()  == null
+```
+
+`subnetMaskFromPrefixLength()` will return an IPv4 netmask for a valid CIDR prefix length.
+
+```js
+ipaddr.IPv4.subnetMaskFromPrefixLength(24) == "255.255.255.0"
+ipaddr.IPv4.subnetMaskFromPrefixLength(29) == "255.255.255.248"
+```
+
+`broadcastAddressFromCIDR()` will return the broadcast address for a given IPv4 interface and netmask in CIDR notation.
+```js
+ipaddr.IPv4.broadcastAddressFromCIDR("172.0.0.1/24") == "172.0.0.255"
+```
+`networkAddressFromCIDR()` will return the network address for a given IPv4 interface and netmask in CIDR notation.
+```js
+ipaddr.IPv4.networkAddressFromCIDR("172.0.0.1/24") == "172.0.0.0"
+```
+
+#### Conversion
+
+IPv4 and IPv6 can be converted bidirectionally to and from network byte order (MSB) byte arrays.
+
+The `fromByteArray()` method will take an array and create an appropriate IPv4 or IPv6 object
+if the input satisfies the requirements. For IPv4 it has to be an array of four 8-bit values,
+while for IPv6 it has to be an array of sixteen 8-bit values.
+
+For example:
+```js
+var addr = ipaddr.fromByteArray([0x7f, 0, 0, 1]);
+addr.toString(); // => "127.0.0.1"
+```
+
+or
+
+```js
+var addr = ipaddr.fromByteArray([0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1])
+addr.toString(); // => "2001:db8::1"
+```
+
+Both objects also offer a `toByteArray()` method, which returns an array in network byte order (MSB).
+
+For example:
+```js
+var addr = ipaddr.parse("127.0.0.1");
+addr.toByteArray(); // => [0x7f, 0, 0, 1]
+```
+
+or
+
+```js
+var addr = ipaddr.parse("2001:db8::1");
+addr.toByteArray(); // => [0x20, 1, 0xd, 0xb8, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 1]
+```

+
+Simple RFC 6838 media type parser
+
+## Installation
+
+```sh
+$ npm install media-typer
+```
+
+## API
+
+```js
+var typer = require('media-typer')
+```
+
+### typer.parse(string)
+
+```js
+var obj = typer.parse('image/svg+xml; charset=utf-8')
+```
+
+Parse a media type string. This will return an object with the following
+properties (examples are shown for the string `'image/svg+xml; charset=utf-8'`):
+
+ - `type`: The type of the media type (always lower case). Example: `'image'`
+
+ - `subtype`: The subtype of the media type (always lower case). Example: `'svg'`
+
+ - `suffix`: The suffix of the media type (always lower case). Example: `'xml'`
+
+ - `parameters`: An object of the parameters in the media type (name of parameter always lower case). Example: `{charset: 'utf-8'}`
+
+### typer.parse(req)
+
+```js
+var obj = typer.parse(req)
+```
+
+Parse the `content-type` header from the given `req`. Short-cut for
+`typer.parse(req.headers['content-type'])`.
+
+### typer.parse(res)
+
+```js
+var obj = typer.parse(res)
+```
+
+Parse the `content-type` header set on the given `res`. Short-cut for
+`typer.parse(res.getHeader('content-type'))`.
+
+### typer.format(obj)
+
+```js
+var obj = typer.format({type: 'image', subtype: 'svg', suffix: 'xml'})
+```
+
+Format an object into a media type string. This will return a string of the
+mime type for the given object. For the properties of the object, see the
+documentation for `typer.parse(string)`.

+Merge objects using descriptors.
+
+```js
+var thing = {
+  get name() {
+    return 'jon'
+  }
+}
+
+var animal = {
+

+
+## API
+
+### merge(destination, source)
+
+Redefines `destination`'s descriptors with `source`'s.
+
+### merge(destination, source, false)
+
+Defines `source`'s descriptors on `destination` if `destination` does not have
+a descriptor by the same name.

+
+HTTP verbs that Node.js core's HTTP parser supports.
+
+This module provides an export that is just like `http.METHODS` from Node.js core,
+with the following differences:
+
+  * All method names are lower-cased.
+  * Contains a fallback list of methods for Node.js versions that do not have a
+    `http.METHODS` export (0.10 and lower).
+  * Provides the fallback list when using tools like `browserify` without pulling
+    in the `http` shim module.
+
+## Install
+
+```bash
+$ npm install methods
+```
+
+## API
+
+```js
+var methods = require('methods')
+```
+
+### methods
+
+This is an array of lower-cased method names that Node.js supports. If Node.js
+provides the `http.METHODS` export, then this is the same array lower-cased,
+otherwise it is a snapshot of the verbs from Node.js 0.10.

+
+[![NPM Version][npm-version-image]][npm-url]
+[![NPM Downloads][npm-downloads-image]][npm-url]
+[![Node.js Version][node-image]][node-url]
+[![Build Status][travis-image]][travis-url]
+[![Coverage Status][coveralls-image]][coveralls-url]
+
+This is a database of all mime types.
+It consists of a single, public JSON file and does not include any logic,
+allowing it to remain as un-opinionated as possible with an API.
+It aggregates data from the following sources:
+
+- http://www.iana.org/assignments/media-types/media-types.xhtml
+- http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types
+- http://hg.nginx.org/nginx/raw-file/default/conf/mime.types
+
+## Installation
+
+```bash
+npm install mime-db
+```
+
+### Database Download
+
+If you're crazy enough to use this in the browser, you can just grab the
+JSON file using [RawGit](https://rawgit.com/). It is recommended to replace
+`master` with [a release tag](https://github.com/jshttp/mime-db/tags) as the
+JSON format may change in the future.
+
+```
+https://cdn.rawgit.com/jshttp/mime-db/master/db.json
+```
+
+## Usage
+
+```js
+var db = require('mime-db');
+
+// grab data on .js files
+var data = db['application/javascript'];
+```
+
+## Data Structure
+
+The JSON file is a map lookup for lowercased mime types.
+Each mime type has the following properties:
+
+- `.source` - where the mime type is defined.
+    If not set, it's probably a custom media type.
+    - `apache` - [Apache common media types](http://svn.apache.org/repos/asf/httpd/httpd/trunk/docs/conf/mime.types)
+    - `iana` - [IANA-defined media types](http://www.iana.org/assignments/media-types/media-types.xhtml)
+    - `nginx` - [nginx media types](http://hg.nginx.org/nginx/raw-file/default/conf/mime.types)
+- `.extensions[]` - known extensions associated with this mime type.
+- `.compressible` - whether a file of this type can be gzipped.
+- `.charset` - the default charset associated with this type, if any.
+
+If unknown, every property could be `undefined`.
+
+## Contributing
+
+To edit the database, only make PRs against `src/custom.json` or
+`src/custom-suffix.json`.
+
+The `src/custom.json` file is a JSON object with the MIME type as the keys
+and the values being an object with the following keys:
+
+- `compressible` - leave out if you don't know, otherwise `true`/`false` for
+  if the data represented by the time is typically compressible.
+- `extensions` - include an array of file extensions that are associated with
+  the type.
+- `notes` - human-readable notes about the type, typically what the type is.
+- `sources` - include an array of URLs of where the MIME type and the associated
+  extensions are sourced from. This needs to be a [primary source](https://en.wikipedia.org/wiki/Primary_source);
+  links to type aggregating sites and Wikipedia are _not acceptible_.
+
+To update the build, run `npm run build`.
+
+## Adding Custom Media Types
+
+The best way to get new media types included in this library is to register
+them with the IANA. The community registration procedure is outlined in
+[RFC 6838 section 5](http://tools.ietf.org/html/rfc6838#section-5). Types
+registered with the IANA are automatically pulled into this library.

+
+The ultimate javascript content-type utility.
+
+Similar to [the `mime` module](https://www.npmjs.com/package/mime), except:
+
+- __No fallbacks.__ Instead of naively returning the first available type,
+  `mime-types` simply returns `false`, so do
+  `var type = mime.lookup('unrecognized') || 'application/octet-stream'`.
+- No `new Mime()` business, so you could do `var lookup = require('mime-types').lookup`.
+- No `.define()` functionality
+- Bug fixes for `.lookup(path)`
+
+Otherwise, the API is compatible.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install mime-types
+```
+
+## Adding Types
+
+All mime types are based on [mime-db](https://www.npmjs.com/package/mime-db),
+so open a PR there if you'd like to add mime types.
+
+## API
+
+```js
+var mime = require('mime-types')
+```
+
+All functions return `false` if input is invalid or not found.
+
+### mime.lookup(path)
+
+Lookup the content-type associated with a file.
+
+```js
+mime.lookup('json')             // 'application/json'
+mime.lookup('.md')              // 'text/markdown'
+mime.lookup('file.html')        // 'text/html'
+mime.lookup('folder/file.js')   // 'application/javascript'
+mime.lookup('folder/.htaccess') // false
+
+mime.lookup('cats') // false
+```
+
+### mime.contentType(type)
+
+Create a full content-type header given a content-type or extension.
+
+```js
+mime.contentType('markdown')  // 'text/x-markdown; charset=utf-8'
+mime.contentType('file.json') // 'application/json; charset=utf-8'
+
+// from a full path
+mime.contentType(path.extname('/path/to/file.json')) // 'application/json; charset=utf-8'
+```
+
+### mime.extension(type)
+
+Get the default extension for a content-type.
+
+```js
+mime.extension('application/octet-stream') // 'bin'
+```
+
+### mime.charset(type)
+
+Lookup the implied default charset of a content-type.
+
+```js
+mime.charset('text/markdown') // 'UTF-8'
+```
+
+### var type = mime.types[extension]
+
+A map of content-types by extension.
+
+### [extensions...] = mime.extensions[type]
+
+A map of extensions by content-type.

+# mime
+
+Comprehensive MIME type mapping API based on mime-db module.
+
+## Install
+
+Install with [npm](http://github.com/isaacs/npm):
+
+    npm install mime
+
+## Contributing / Testing
+
+    npm run test
+
+## Command Line
+
+    mime [path_string]
+
+E.g.
+
+    > mime scripts/jquery.js
+    application/javascript
+
+## API - Queries
+
+### mime.lookup(path)
+Get the mime type associated with a file, if no mime type is found `application/octet-stream` is returned. Performs a case-insensitive lookup using the extension in `path` (the substring after the last '/' or '.').  E.g.
+
+```js
+var mime = require('mime');
+
+mime.lookup('/path/to/file.txt');         // => 'text/plain'
+mime.lookup('file.txt');                  // => 'text/plain'
+mime.lookup('.TXT');                      // => 'text/plain'
+mime.lookup('htm');                       // => 'text/html'
+```
+
+### mime.default_type
+Sets the mime type returned when `mime.lookup` fails to find the extension searched for. (Default is `application/octet-stream`.)
+
+### mime.extension(type)
+Get the default extension for `type`
+
+```js
+mime.extension('text/html');                 // => 'html'
+mime.extension('application/octet-stream');  // => 'bin'
+```
+
+### mime.charsets.lookup()
+
+Map mime-type to charset
+
+```js
+mime.charsets.lookup('text/plain');        // => 'UTF-8'
+```
+
+(The logic for charset lookups is pretty rudimentary.  Feel free to suggest improvements.)
+
+## API - Defining Custom Types
+
+Custom type mappings can be added on a per-project basis via the following APIs.
+
+### mime.define()
+
+Add custom mime/extension mappings
+
+```js
+mime.define({
+    'text/x-some-format': ['x-sf', 'x-sft', 'x-sfml'],
+    'application/x-my-type': ['x-mt', 'x-mtt'],
+    // etc ...
+});
+
+mime.lookup('x-sft');                 // => 'text/x-some-format'
+```
+
+The first entry in the extensions array is returned by `mime.extension()`. E.g.
+
+```js
+mime.extension('text/x-some-format'); // => 'x-sf'
+```
+
+### mime.load(filepath)
+
+Load mappings from an Apache ".types" format file
+
+```js
+mime.load('./my_project.types');
+```
+The .types file format is simple -  See the `types` dir for examples.

+# ms
+
+[![Build Status](https://travis-ci.org/zeit/ms.svg?branch=master)](https://travis-ci.org/zeit/ms)
+[![Slack Channel](http://zeit-slackin.now.sh/badge.svg)](https://zeit.chat/)
+
+Use this package to easily convert various time formats to milliseconds.
+
+## Examples
+
+```js
+ms('2 days')  // 172800000
+ms('1d')      // 86400000
+ms('10h')     // 36000000
+ms('2.5 hrs') // 9000000
+ms('2h')      // 7200000
+ms('1m')      // 60000
+ms('5s')      // 5000
+ms('1y')      // 31557600000
+ms('100')     // 100
+```
+
+### Convert from milliseconds
+
+```js
+ms(60000)             // "1m"
+ms(2 * 60000)         // "2m"
+ms(ms('10 hours'))    // "10h"
+```
+
+### Time format written-out
+
+```js
+ms(60000, { long: true })             // "1 minute"
+ms(2 * 60000, { long: true })         // "2 minutes"
+ms(ms('10 hours'), { long: true })    // "10 hours"
+```
+
+## Features
+
+- Works both in [node](https://nodejs.org) and in the browser.
+- If a number is supplied to `ms`, a string with a unit is returned.
+- If a string that contains the number is supplied, it returns it as a number (e.g.: it returns `100` for `'100'`).
+- If you pass a string with a number and a valid unit, the number of equivalent ms is returned.
+
+## Caught a bug?
+
+1. [Fork](https://help.github.com/articles/fork-a-repo/) this repository to your own GitHub account and then [clone](https://help.github.com/articles/cloning-a-repository/) it to your local device
+2. Link the package to the global module directory: `npm link`
+3. Within the module you want to test your local development instance of ms, just link it to the dependencies: `npm link ms`. Instead of the default one from npm, node will now use your clone of ms!
+
+As always, you can run the tests using: `npm test`

+
+Execute a callback when a HTTP request closes, finishes, or errors.
+
+## Install
+
+```sh
+$ npm install on-finished
+```
+
+## API
+
+```js
+var onFinished = require('on-finished')
+```
+
+### onFinished(res, listener)
+
+Attach a listener to listen for the response to finish. The listener will
+be invoked only once when the response finished. If the response finished
+to an error, the first argument will contain the error. If the response
+has already finished, the listener will be invoked.
+
+Listening to the end of a response would be used to close things associated
+with the response, like open files.
+
+Listener is invoked as `listener(err, res)`.
+
+```js
+onFinished(res, function (err, res) {
+  // clean up open fds, etc.
+  // err contains the error is request error'd
+})
+```
+
+### onFinished(req, listener)
+
+Attach a listener to listen for the request to finish. The listener will
+be invoked only once when the request finished. If the request finished
+to an error, the first argument will contain the error. If the request
+has already finished, the listener will be invoked.
+
+Listening to the end of a request would be used to know when to continue
+after reading the data.
+
+Listener is invoked as `listener(err, req)`.
+
+```js
+var data = ''
+
+req.setEncoding('utf8')
+res.on('data', function (str) {
+  data += str
+})
+
+onFinished(req, function (err, req) {
+  // data is read unless there is err
+})
+```
+
+### onFinished.isFinished(res)
+
+Determine if `res` is already finished. This would be useful to check and
+not even start certain operations if the response has already finished.
+
+### onFinished.isFinished(req)
+
+Determine if `req` is already finished. This would be useful to check and
+not even start certain operations if the request has already finished.
+
+## Special Node.js requests
+
+### HTTP CONNECT method
+
+The meaning of the `CONNECT` method from RFC 7231, section 4.3.6:
+
+> The CONNECT method requests that the recipient establish a tunnel to
+> the destination origin server identified by the request-target and,
+> if successful, thereafter restrict its behavior to blind forwarding
+> of packets, in both directions, until the tunnel is closed.  Tunnels
+> are commonly used to create an end-to-end virtual connection, through
+> one or more proxies, which can then be secured using TLS (Transport
+> Layer Security, [RFC5246]).
+
+In Node.js, these request objects come from the `'connect'` event on
+the HTTP server.
+
+When this module is used on a HTTP `CONNECT` request, the request is
+considered "finished" immediately, **due to limitations in the Node.js
+interface**. This means if the `CONNECT` request contains a request entity,
+the request will be considered "finished" even before it has been read.
+
+There is no such thing as a response object to a `CONNECT` request in
+Node.js, so there is no support for for one.
+
+### HTTP Upgrade request
+
+The meaning of the `Upgrade` header from RFC 7230, section 6.1:
+
+> The "Upgrade" header field is intended to provide a simple mechanism
+> for transitioning from HTTP/1.1 to some other protocol on the same
+> connection.
+
+In Node.js, these request objects come from the `'upgrade'` event on
+the HTTP server.
+
+When this module is used on a HTTP request with an `Upgrade` header, the
+request is considered "finished" immediately, **due to limitations in the
+Node.js interface**. This means if the `Upgrade` request contains a request
+entity, the request will be considered "finished" even before it has been
+read.
+
+There is no such thing as a response object to a `Upgrade` request in
+Node.js, so there is no support for for one.
+
+## Example
+
+The following code ensures that file descriptors are always closed
+once the response finishes.

+
+Parse a URL with memoization.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install parseurl
+```
+
+## API
+
+```js
+var parseurl = require('parseurl')
+```
+
+### parseurl(req)
+
+Parse the URL of the given request object (looks at the `req.url` property)
+and return the result. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.url` does
+not change will return a cached parsed object, rather than parsing again.
+
+### parseurl.original(req)
+
+Parse the original URL of the given request object and return the result.
+This works by trying to parse `req.originalUrl` if it is a string, otherwise
+parses `req.url`. The result is the same as `url.parse` in Node.js core.
+Calling this function multiple times on the same `req` where `req.originalUrl`
+does not change will return a cached parsed object, rather than parsing again.

+# Path-to-RegExp
+
+Turn an Express-style path string such as `/user/:name` into a regular expression.
+
+**Note:** This is a legacy branch. You should upgrade to `1.x`.
+
+## Usage
+
+```javascript
+var pathToRegexp = require('path-to-regexp');
+```
+
+### pathToRegexp(path, keys, options)
+
+ - **path** A string in the express format, an array of such strings, or a regular expression
+ - **keys** An array to be populated with the keys present in the url.  Once the function completes, this will be an array of strings.
+ - **options**
+   - **options.sensitive** Defaults to false, set this to true to make routes case sensitive
+   - **options.strict** Defaults to false, set this to true to make the trailing slash matter.
+   - **options.end** Defaults to true, set this to false to only match the prefix of the URL.
+
+```javascript
+var keys = [];
+var exp = pathToRegexp('/foo/:bar', keys);
+//keys = ['bar']
+//exp = /^\/foo\/(?:([^\/]+?))\/?$/i
+```
+
+## Live Demo
+
+You can see a live demo of this library in use at [express-route-tester](http://forbeslindesay.github.com/express-route-tester/).

+Determine address of proxied request
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install proxy-addr
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var proxyaddr = require('proxy-addr')
+```
+
+### proxyaddr(req, trust)
+
+Return the address of the request, using the given `trust` parameter.
+
+The `trust` argument is a function that returns `true` if you trust
+the address, `false` if you don't. The closest untrusted address is
+returned.
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, function (addr) { return addr === '127.0.0.1' })
+proxyaddr(req, function (addr, i) { return i < 1 })
+```
+
+The `trust` arugment may also be a single IP address string or an
+array of trusted addresses, as plain IP addresses, CIDR-formatted
+strings, or IP/netmask strings.
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, '127.0.0.1')
+proxyaddr(req, ['127.0.0.0/8', '10.0.0.0/8'])
+proxyaddr(req, ['127.0.0.0/255.0.0.0', '192.168.0.0/255.255.0.0'])
+```
+
+This module also supports IPv6. Your IPv6 addresses will be normalized
+automatically (i.e. `fe80::00ed:1` equals `fe80:0:0:0:0:0:ed:1`).
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, '::1')
+proxyaddr(req, ['::1/128', 'fe80::/10'])
+```
+
+This module will automatically work with IPv4-mapped IPv6 addresses
+as well to support node.js in IPv6-only mode. This means that you do
+not have to specify both `::ffff:a00:1` and `10.0.0.1`.
+
+As a convenience, this module also takes certain pre-defined names
+in addition to IP addresses, which expand into IP addresses:
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr(req, 'loopback')
+proxyaddr(req, ['loopback', 'fc00:ac:1ab5:fff::1/64'])
+```
+
+  * `loopback`: IPv4 and IPv6 loopback addresses (like `::1` and
+    `127.0.0.1`).
+  * `linklocal`: IPv4 and IPv6 link-local addresses (like
+    `fe80::1:1:1:1` and `169.254.0.1`).
+  * `uniquelocal`: IPv4 private addresses and IPv6 unique-local
+    addresses (like `fc00:ac:1ab5:fff::1` and `192.168.0.1`).
+
+When `trust` is specified as a function, it will be called for each
+address to determine if it is a trusted address. The function is
+given two arguments: `addr` and `i`, where `addr` is a string of
+the address to check and `i` is a number that represents the distance
+from the socket address.
+
+### proxyaddr.all(req, [trust])
+
+Return all the addresses of the request, optionally stopping at the
+first untrusted. This array is ordered from closest to furthest
+(i.e. `arr[0] === req.connection.remoteAddress`).
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr.all(req)
+```
+
+The optional `trust` argument takes the same arguments as `trust`
+does in `proxyaddr(req, trust)`.
+
+<!-- eslint-disable no-undef -->
+
+```js
+proxyaddr.all(req, 'loopback')
+```
+
+### proxyaddr.compile(val)
+
+Compiles argument `val` into a `trust` function. This function takes
+the same arguments as `trust` does in `proxyaddr(req, trust)` and
+returns a function suitable for `proxyaddr(req, trust)`.
+
+<!-- eslint-disable no-undef, no-unused-vars -->
+
+```js
+var trust = proxyaddr.compile('localhost')
+var addr = proxyaddr(req, trust)
+```
+
+This function is meant to be optimized for use against every request.
+It is recommend to compile a trust function up-front for the trusted
+configuration and pass that to `proxyaddr(req, trust)` for each request.
+

+
+A querystring parsing and stringifying library with some added security.
+
+Lead Maintainer: [Jordan Harband](https://github.com/ljharb)
+
+The **qs** module was originally created and maintained by [TJ Holowaychuk](https://github.com/visionmedia/node-querystring).
+
+## Usage
+
+```javascript
+var qs = require('qs');
+var assert = require('assert');
+
+var obj = qs.parse('a=c');
+assert.deepEqual(obj, { a: 'c' });
+
+var str = qs.stringify(obj);
+assert.equal(str, 'a=c');
+```
+
+### Parsing Objects
+
+[](#preventEval)
+```javascript
+qs.parse(string, [options]);
+```
+
+**qs** allows you to create nested objects within your query strings, by surrounding the name of sub-keys with square brackets `[]`.
+For example, the string `'foo[bar]=baz'` converts to:
+
+```javascript
+assert.deepEqual(qs.parse('foo[bar]=baz'), {
+    foo: {
+        bar: 'baz'
+    }
+});
+```
+
+When using the `plainObjects` option the parsed value is returned as a null object, created via `Object.create(null)` and as such you should be aware that prototype methods will not exist on it and a user may set those names to whatever value they like:
+
+```javascript
+var nullObject = qs.parse('a[hasOwnProperty]=b', { plainObjects: true });
+assert.deepEqual(nullObject, { a: { hasOwnProperty: 'b' } });
+```
+
+By default parameters that would overwrite properties on the object prototype are ignored, if you wish to keep the data from those fields either use `plainObjects` as mentioned above, or set `allowPrototypes` to `true` which will allow user input to overwrite those properties. *WARNING* It is generally a bad idea to enable this option as it can cause problems when attempting to use the properties that have been overwritten. Always be careful with this option.
+
+```javascript
+var protoObject = qs.parse('a[hasOwnProperty]=b', { allowPrototypes: true });
+assert.deepEqual(protoObject, { a: { hasOwnProperty: 'b' } });
+```
+
+URI encoded strings work too:
+
+```javascript
+assert.deepEqual(qs.parse('a%5Bb%5D=c'), {
+    a: { b: 'c' }
+});
+```
+
+You can also nest your objects, like `'foo[bar][baz]=foobarbaz'`:
+
+```javascript
+assert.deepEqual(qs.parse('foo[bar][baz]=foobarbaz'), {
+    foo: {
+        bar: {
+            baz: 'foobarbaz'
+        }
+    }
+});
+```
+
+By default, when nesting objects **qs** will only parse up to 5 children deep. This means if you attempt to parse a string like
+`'a[b][c][d][e][f][g][h][i]=j'` your resulting object will be:
+
+```javascript
+var expected = {
+    a: {
+        b: {
+            c: {
+                d: {
+                    e: {
+                        f: {
+                            '[g][h][i]': 'j'
+                        }
+                    }
+                }
+            }
+        }
+    }
+};
+var string = 'a[b][c][d][e][f][g][h][i]=j';
+assert.deepEqual(qs.parse(string), expected);
+```
+
+This depth can be overridden by passing a `depth` option to `qs.parse(string, [options])`:
+
+```javascript
+var deep = qs.parse('a[b][c][d][e][f][g][h][i]=j', { depth: 1 });
+assert.deepEqual(deep, { a: { b: { '[c][d][e][f][g][h][i]': 'j' } } });
+```
+
+The depth limit helps mitigate abuse when **qs** is used to parse user input, and it is recommended to keep it a reasonably small number.
+
+For similar reasons, by default **qs** will only parse up to 1000 parameters. This can be overridden by passing a `parameterLimit` option:
+
+```javascript
+var limited = qs.parse('a=b&c=d', { parameterLimit: 1 });
+assert.deepEqual(limited, { a: 'b' });
+```
+
+To bypass the leading question mark, use `ignoreQueryPrefix`:
+
+```javascript
+var prefixed = qs.parse('?a=b&c=d', { ignoreQueryPrefix: true });
+assert.deepEqual(prefixed, { a: 'b', c: 'd' });
+```
+
+An optional delimiter can also be passed:
+
+```javascript
+var delimited = qs.parse('a=b;c=d', { delimiter: ';' });
+assert.deepEqual(delimited, { a: 'b', c: 'd' });
+```
+
+Delimiters can be a regular expression too:
+
+```javascript
+var regexed = qs.parse('a=b;c=d,e=f', { delimiter: /[;,]/ });
+assert.deepEqual(regexed, { a: 'b', c: 'd', e: 'f' });
+```
+
+Option `allowDots` can be used to enable dot notation:
+
+```javascript
+var withDots = qs.parse('a.b=c', { allowDots: true });
+assert.deepEqual(withDots, { a: { b: 'c' } });
+```
+
+### Parsing Arrays
+
+**qs** can also parse arrays using a similar `[]` notation:
+
+```javascript
+var withArray = qs.parse('a[]=b&a[]=c');
+assert.deepEqual(withArray, { a: ['b', 'c'] });
+```
+
+You may specify an index as well:
+
+```javascript
+var withIndexes = qs.parse('a[1]=c&a[0]=b');
+assert.deepEqual(withIndexes, { a: ['b', 'c'] });
+```
+
+Note that the only difference between an index in an array and a key in an object is that the value between the brackets must be a number
+to create an array. When creating arrays with specific indices, **qs** will compact a sparse array to only the existing values preserving
+their order:
+
+```javascript
+var noSparse = qs.parse('a[1]=b&a[15]=c');
+assert.deepEqual(noSparse, { a: ['b', 'c'] });
+```
+
+Note that an empty string is also a value, and will be preserved:
+
+```javascript
+var withEmptyString = qs.parse('a[]=&a[]=b');
+assert.deepEqual(withEmptyString, { a: ['', 'b'] });
+
+var withIndexedEmptyString = qs.parse('a[0]=b&a[1]=&a[2]=c');
+assert.deepEqual(withIndexedEmptyString, { a: ['b', '', 'c'] });
+```
+
+**qs** will also limit specifying indices in an array to a maximum index of `20`. Any array members with an index of greater than `20` will
+instead be converted to an object with the index as the key:
+
+```javascript
+var withMaxIndex = qs.parse('a[100]=b');
+assert.deepEqual(withMaxIndex, { a: { '100': 'b' } });
+```
+
+This limit can be overridden by passing an `arrayLimit` option:
+
+```javascript
+var withArrayLimit = qs.parse('a[1]=b', { arrayLimit: 0 });
+assert.deepEqual(withArrayLimit, { a: { '1': 'b' } });
+```
+
+To disable array parsing entirely, set `parseArrays` to `false`.
+
+```javascript
+var noParsingArrays = qs.parse('a[]=b', { parseArrays: false });
+assert.deepEqual(noParsingArrays, { a: { '0': 'b' } });
+```
+
+If you mix notations, **qs** will merge the two items into an object:
+
+```javascript
+var mixedNotation = qs.parse('a[0]=b&a[b]=c');
+assert.deepEqual(mixedNotation, { a: { '0': 'b', b: 'c' } });
+```
+
+You can also create arrays of objects:
+
+```javascript
+var arraysOfObjects = qs.parse('a[][b]=c');
+assert.deepEqual(arraysOfObjects, { a: [{ b: 'c' }] });
+```
+
+### Stringifying
+
+[](#preventEval)
+```javascript
+qs.stringify(object, [options]);
+```
+
+When stringifying, **qs** by default URI encodes output. Objects are stringified as you would expect:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b' }), 'a=b');
+assert.equal(qs.stringify({ a: { b: 'c' } }), 'a%5Bb%5D=c');
+```
+
+This encoding can be disabled by setting the `encode` option to `false`:
+
+```javascript
+var unencoded = qs.stringify({ a: { b: 'c' } }, { encode: false });
+assert.equal(unencoded, 'a[b]=c');
+```
+
+Encoding can be disabled for keys by setting the `encodeValuesOnly` option to `true`:
+```javascript
+var encodedValues = qs.stringify(
+    { a: 'b', c: ['d', 'e=f'], f: [['g'], ['h']] },
+    { encodeValuesOnly: true }
+);
+assert.equal(encodedValues,'a=b&c[0]=d&c[1]=e%3Df&f[0][0]=g&f[1][0]=h');
+```
+
+This encoding can also be replaced by a custom encoding method set as `encoder` option:
+
+```javascript
+var encoded = qs.stringify({ a: { b: 'c' } }, { encoder: function (str) {
+    // Passed in values `a`, `b`, `c`
+    return // Return encoded string
+}})
+```
+
+_(Note: the `encoder` option does not apply if `encode` is `false`)_
+
+Analogue to the `encoder` there is a `decoder` option for `parse` to override decoding of properties and values:
+
+```javascript
+var decoded = qs.parse('x=z', { decoder: function (str) {
+    // Passed in values `x`, `z`
+    return // Return decoded string
+}})
+```
+
+Examples beyond this point will be shown as though the output is not URI encoded for clarity. Please note that the return values in these cases *will* be URI encoded during real usage.
+
+When arrays are stringified, by default they are given explicit indices:
+
+```javascript
+qs.stringify({ a: ['b', 'c', 'd'] });
+// 'a[0]=b&a[1]=c&a[2]=d'
+```
+
+You may override this by setting the `indices` option to `false`:
+
+```javascript
+qs.stringify({ a: ['b', 'c', 'd'] }, { indices: false });
+// 'a=b&a=c&a=d'
+```
+
+You may use the `arrayFormat` option to specify the format of the output array:
+
+```javascript
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'indices' })
+// 'a[0]=b&a[1]=c'
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'brackets' })
+// 'a[]=b&a[]=c'
+qs.stringify({ a: ['b', 'c'] }, { arrayFormat: 'repeat' })
+// 'a=b&a=c'
+```
+
+When objects are stringified, by default they use bracket notation:
+
+```javascript
+qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
+// 'a[b][c]=d&a[b][e]=f'
+```
+
+You may override this to use dot notation by setting the `allowDots` option to `true`:
+
+```javascript
+qs.stringify({ a: { b: { c: 'd', e: 'f' } } }, { allowDots: true });
+// 'a.b.c=d&a.b.e=f'
+```
+
+Empty strings and null values will omit the value, but the equals sign (=) remains in place:
+
+```javascript
+assert.equal(qs.stringify({ a: '' }), 'a=');
+```
+
+Key with no values (such as an empty object or array) will return nothing:
+
+```javascript
+assert.equal(qs.stringify({ a: [] }), '');
+assert.equal(qs.stringify({ a: {} }), '');
+assert.equal(qs.stringify({ a: [{}] }), '');
+assert.equal(qs.stringify({ a: { b: []} }), '');
+assert.equal(qs.stringify({ a: { b: {}} }), '');
+```
+
+Properties that are set to `undefined` will be omitted entirely:
+
+```javascript
+assert.equal(qs.stringify({ a: null, b: undefined }), 'a=');
+```
+
+The query string may optionally be prepended with a question mark:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b', c: 'd' }, { addQueryPrefix: true }), '?a=b&c=d');
+```
+
+The delimiter may be overridden with stringify as well:
+
+```javascript
+assert.equal(qs.stringify({ a: 'b', c: 'd' }, { delimiter: ';' }), 'a=b;c=d');
+```
+
+If you only want to override the serialization of `Date` objects, you can provide a `serializeDate` option:
+
+```javascript
+var date = new Date(7);
+assert.equal(qs.stringify({ a: date }), 'a=1970-01-01T00:00:00.007Z'.replace(/:/g, '%3A'));
+assert.equal(
+    qs.stringify({ a: date }, { serializeDate: function (d) { return d.getTime(); } }),
+    'a=7'
+);
+```
+
+You may use the `sort` option to affect the order of parameter keys:
+
+```javascript
+function alphabeticalSort(a, b) {
+    return a.localeCompare(b);
+}
+assert.equal(qs.stringify({ a: 'c', z: 'y', b : 'f' }, { sort: alphabeticalSort }), 'a=c&b=f&z=y');
+```
+
+Finally, you can use the `filter` option to restrict which keys will be included in the stringified output.
+If you pass a function, it will be called for each key to obtain the replacement value. Otherwise, if you
+pass an array, it will be used to select properties and array indices for stringification:
+
+```javascript
+function filterFunc(prefix, value) {
+    if (prefix == 'b') {
+        // Return an `undefined` value to omit a property.
+        return;
+    }
+    if (prefix == 'e[f]') {
+        return value.getTime();
+    }
+    if (prefix == 'e[g][0]') {
+        return value * 2;
+    }
+    return value;
+}
+qs.stringify({ a: 'b', c: 'd', e: { f: new Date(123), g: [2] } }, { filter: filterFunc });
+// 'a=b&c=d&e[f]=123&e[g][0]=4'
+qs.stringify({ a: 'b', c: 'd', e: 'f' }, { filter: ['a', 'e'] });
+// 'a=b&e=f'
+qs.stringify({ a: ['b', 'c', 'd'], e: 'f' }, { filter: ['a', 0, 2] });
+// 'a[0]=b&a[2]=d'
+```
+
+### Handling of `null` values
+
+By default, `null` values are treated like empty strings:
+
+```javascript
+var withNull = qs.stringify({ a: null, b: '' });
+assert.equal(withNull, 'a=&b=');
+```
+
+Parsing does not distinguish between parameters with and without equal signs. Both are converted to empty strings.
+
+```javascript
+var equalsInsensitive = qs.parse('a&b=');
+assert.deepEqual(equalsInsensitive, { a: '', b: '' });
+```
+
+To distinguish between `null` values and empty strings use the `strictNullHandling` flag. In the result string the `null`
+values have no `=` sign:
+
+```javascript
+var strictNull = qs.stringify({ a: null, b: '' }, { strictNullHandling: true });
+assert.equal(strictNull, 'a&b=');
+```
+
+To parse values without `=` back to `null` use the `strictNullHandling` flag:
+
+```javascript
+var parsedStrictNull = qs.parse('a&b=', { strictNullHandling: true });
+assert.deepEqual(parsedStrictNull, { a: null, b: '' });
+```
+
+To completely skip rendering keys with `null` values, use the `skipNulls` flag:
+
+```javascript
+var nullsSkipped = qs.stringify({ a: 'b', c: null}, { skipNulls: true });
+assert.equal(nullsSkipped, 'a=b');
+```
+
+### Dealing with special character sets
+
+By default the encoding and decoding of characters is done in `utf-8`. If you
+wish to encode querystrings to a different character set (i.e.
+[Shift JIS](https://en.wikipedia.org/wiki/Shift_JIS)) you can use the
+[`qs-iconv`](https://github.com/martinheidegger/qs-iconv) library:
+
+```javascript
+var encoder = require('qs-iconv/encoder')('shift_jis');
+var shiftJISEncoded = qs.stringify({ a: 'こんにちは！' }, { encoder: encoder });
+assert.equal(shiftJISEncoded, 'a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I');
+```
+
+This also works for decoding of query strings:
+
+```javascript
+var decoder = require('qs-iconv/decoder')('shift_jis');
+var obj = qs.parse('a=%82%B1%82%F1%82%C9%82%BF%82%CD%81I', { decoder: decoder });
+assert.deepEqual(obj, { a: 'こんにちは！' });
+```
+
+### RFC 3986 and RFC 1738 space encoding
+
+RFC3986 used as default option and encodes ' ' to *%20* which is backward compatible.
+In the same time, output can be stringified as per RFC1738 with ' ' equal to '+'.
+
+```
+assert.equal(qs.stringify({ a: 'b c' }), 'a=b%20c');
+assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC3986' }), 'a=b%20c');
+assert.equal(qs.stringify({ a: 'b c' }, { format : 'RFC1738' }), 'a=b+c');
+```

+
+Range header field parser.
+
+## Installation
+
+```
+$ npm install range-parser
+```
+
+## API
+
+```js
+var parseRange = require('range-parser')
+```
+
+### parseRange(size, header, options)
+
+Parse the given `header` string where `size` is the maximum size of the resource.
+An array of ranges will be returned or negative numbers indicating an error parsing.
+
+  * `-2` signals a malformed header string
+  * `-1` signals an unsatisfiable range
+
+```js
+// parse header from request
+var range = parseRange(size, req.headers.range)
+
+// the type of the range
+if (range.type === 'bytes') {
+  // the ranges
+  range.forEach(function (r) {
+    // do something with r.start and r.end
+  })
+}
+```
+
+#### Options
+
+These properties are accepted in the options object.
+
+##### combine
+
+Specifies if overlapping & adjacent ranges should be combined, defaults to `false`.
+When `true`, ranges will be combined and returned as if they were specified that
+way in the header.
+
+```js
+parseRange(100, 'bytes=50-55,0-10,5-10,56-60', { combine: true })
+// => [
+//      { start: 0,  end: 10 },
+//      { start: 50, end: 60 }
+//    ]
+```

+
+Gets the entire buffer of a stream either as a `Buffer` or a string.
+Validates the stream's length against an expected length and maximum limit.
+Ideal for parsing request bodies.
+
+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install raw-body
+```
+
+### TypeScript
+
+This module includes a [TypeScript](https://www.typescriptlang.org/)
+declarition file to enable auto complete in compatible editors and type
+information for TypeScript projects. This module depends on the Node.js
+types, so install `@types/node`:
+
+```sh
+$ npm install @types/node
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var getRawBody = require('raw-body')
+```
+
+### getRawBody(stream, [options], [callback])
+
+**Returns a promise if no callback specified and global `Promise` exists.**
+
+Options:
+
+- `length` - The length of the stream.
+  If the contents of the stream do not add up to this length,
+  an `400` error code is returned.
+- `limit` - The byte limit of the body.
+  This is the number of bytes or any string format supported by
+  [bytes](https://www.npmjs.com/package/bytes),
+  for example `1000`, `'500kb'` or `'3mb'`.
+  If the body ends up being larger than this limit,
+  a `413` error code is returned.
+- `encoding` - The encoding to use to decode the body into a string.
+  By default, a `Buffer` instance will be returned when no encoding is specified.
+  Most likely, you want `utf-8`, so setting `encoding` to `true` will decode as `utf-8`.
+  You can use any type of encoding supported by [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme).
+
+You can also pass a string in place of options to just specify the encoding.
+
+If an error occurs, the stream will be paused, everything unpiped,
+and you are responsible for correctly disposing the stream.
+For HTTP requests, no handling is required if you send a response.
+For streams that use file descriptors, you should `stream.destroy()` or `stream.close()` to prevent leaks.
+
+## Errors
+
+This module creates errors depending on the error condition during reading.
+The error may be an error from the underlying Node.js implementation, but is
+otherwise an error created by this module, which has the following attributes:
+
+  * `limit` - the limit in bytes
+  * `length` and `expected` - the expected length of the stream
+  * `received` - the received bytes
+  * `encoding` - the invalid encoding
+  * `status` and `statusCode` - the corresponding status code for the error
+  * `type` - the error type
+
+### Types
+
+The errors from this module have a `type` property which allows for the progamatic
+determination of the type of error returned.
+
+#### encoding.unsupported
+
+This error will occur when the `encoding` option is specified, but the value does
+not map to an encoding supported by the [iconv-lite](https://www.npmjs.org/package/iconv-lite#readme)
+module.
+
+#### entity.too.large
+
+This error will occur when the `limit` option is specified, but the stream has
+an entity that is larger.
+
+#### request.aborted
+
+This error will occur when the request stream is aborted by the client before
+reading the body has finished.
+
+#### request.size.invalid
+
+This error will occur when the `length` option is specified, but the stream has
+emitted more bytes.
+
+#### stream.encoding.set
+
+This error will occur when the given stream has an encoding set on it, making it
+a decoded stream. The stream should not have an encoding set and is expected to
+emit `Buffer` objects.
+
+## Examples
+
+### Simple Express example
+
+```js
+var contentType = require('content-type')
+var express = require('express')
+var getRawBody = require('raw-body')
+
+var app = express()
+
+app.use(function (req, res, next) {
+  getRawBody(req, {
+    length: req.headers['content-length'],
+    limit: '1mb',
+    encoding: contentType.parse(req).parameters.charset
+  }, function (err, string) {
+    if (err) return next(err)
+    req.text = string
+    next()
+  })
+})
+
+// now access req.text
+```
+
+### Simple Koa example
+
+```js
+var contentType = require('content-type')
+var getRawBody = require('raw-body')
+var koa = require('koa')
+
+var app = koa()
+
+app.use(function * (next) {
+  this.text = yield getRawBody(this.req, {
+    length: this.req.headers['content-length'],
+    limit: '1mb',
+    encoding: contentType.parse(this.req).parameters.charset
+  })
+  yield next
+})
+
+// now access this.text
+```
+
+### Using as a promise
+
+To use this library as a promise, simply omit the `callback` and a promise is
+returned, provided that a global `Promise` is defined.
+
+```js
+var getRawBody = require('raw-body')
+var http = require('http')
+
+var server = http.createServer(function (req, res) {
+  getRawBody(req)
+  .then(function (buf) {
+    res.statusCode = 200
+    res.end(buf.length + ' bytes submitted')
+  })
+  .catch(function (err) {
+    res.statusCode = 500
+    res.end(err.message)
+  })
+})
+
+server.listen(3000)
+```
+
+### Using with TypeScript
+
+```ts
+import * as getRawBody from 'raw-body';
+import * as http from 'http';
+
+const server = http.createServer((req, res) => {
+  getRawBody(req)
+  .then((buf) => {
+    res.statusCode = 200;
+    res.end(buf.length + ' bytes submitted');
+  })
+  .catch((err) => {
+    res.statusCode = err.statusCode;
+    res.end(err.message);
+  });
+});
+
+server.listen(3000);
+```

+#### Safer Node.js Buffer API
+
+**Use the new Node.js Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in all versions of Node.js.**
+
+**Uses the built-in implementation when available.**
+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+Send is a library for streaming files from the file system as a http response
+supporting partial responses (Ranges), conditional-GET negotiation (If-Match,
+If-Unmodified-Since, If-None-Match, If-Modified-Since), high test coverage,
+and granular events which may be leveraged to take appropriate actions in your
+application or framework.
+
+Looking to serve up entire folders mapped to URLs? Try [serve-static](https://www.npmjs.org/package/serve-static).
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```bash
+$ npm install send
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var send = require('send')
+```
+
+### send(req, path, [options])
+
+Create a new `SendStream` for the given path to send to a `res`. The `req` is
+the Node.js HTTP request and the `path` is a urlencoded path to send (urlencoded,
+not the actual file-system path).
+
+#### Options
+
+##### acceptRanges
+
+Enable or disable accepting ranged requests, defaults to true.
+Disabling this will not send `Accept-Ranges` and ignore the contents
+of the `Range` request header.
+
+##### cacheControl
+
+Enable or disable setting `Cache-Control` response header, defaults to
+true. Disabling this will ignore the `immutable` and `maxAge` options.
+
+##### dotfiles
+
+Set how "dotfiles" are treated when encountered. A dotfile is a file
+or directory that begins with a dot ("."). Note this check is done on
+the path itself without checking if the path actually exists on the
+disk. If `root` is specified, only the dotfiles above the root are
+checked (i.e. the root itself can be within a dotfile when when set
+to "deny").
+
+  - `'allow'` No special treatment for dotfiles.
+  - `'deny'` Send a 403 for any request for a dotfile.
+  - `'ignore'` Pretend like the dotfile does not exist and 404.
+
+The default value is _similar_ to `'ignore'`, with the exception that
+this default will not ignore the files within a directory that begins
+with a dot, for backward-compatibility.
+
+##### end
+
+Byte offset at which the stream ends, defaults to the length of the file
+minus 1. The end is inclusive in the stream, meaning `end: 3` will include
+the 4th byte in the stream.
+
+##### etag
+
+Enable or disable etag generation, defaults to true.
+
+##### extensions
+
+If a given file doesn't exist, try appending one of the given extensions,
+in the given order. By default, this is disabled (set to `false`). An
+example value that will serve extension-less HTML files: `['html', 'htm']`.
+This is skipped if the requested file already has an extension.
+
+##### immutable
+
+Enable or diable the `immutable` directive in the `Cache-Control` response
+header, defaults to `false`. If set to `true`, the `maxAge` option should
+also be specified to enable caching. The `immutable` directive will prevent
+supported clients from making conditional requests during the life of the
+`maxAge` option to check if the file has changed.
+
+##### index
+
+By default send supports "index.html" files, to disable this
+set `false` or to supply a new index pass a string or an array
+in preferred order.
+
+##### lastModified
+
+Enable or disable `Last-Modified` header, defaults to true. Uses the file
+system's last modified value.
+
+##### maxAge
+
+Provide a max-age in milliseconds for http caching, defaults to 0.
+This can also be a string accepted by the
+[ms](https://www.npmjs.org/package/ms#readme) module.
+
+##### root
+
+Serve files relative to `path`.
+
+##### start
+
+Byte offset at which the stream starts, defaults to 0. The start is inclusive,
+meaning `start: 2` will include the 3rd byte in the stream.
+
+#### Events
+
+The `SendStream` is an event emitter and will emit the following events:
+
+  - `error` an error occurred `(err)`
+  - `directory` a directory was requested `(res, path)`
+  - `file` a file was requested `(path, stat)`
+  - `headers` the headers are about to be set on a file `(res, path, stat)`
+  - `stream` file streaming has started `(stream)`
+  - `end` streaming has completed
+
+#### .pipe
+
+The `pipe` method is used to pipe the response into the Node.js HTTP response
+object, typically `send(req, path, options).pipe(res)`.
+
+### .mime
+
+The `mime` export is the global instance of of the
+[`mime` npm module](https://www.npmjs.com/package/mime).
+
+This is used to configure the MIME types that are associated with file extensions
+as well as other options for how to resolve the MIME type of a file (like the
+default type to use for an unknown file extension).
+
+## Error-handling
+
+By default when no `error` listeners are present an automatic response will be
+made, otherwise you have full control over the response, aka you may show a 5xx
+page etc.
+
+## Caching
+
+It does _not_ perform internal caching, you should use a reverse proxy cache
+such as Varnish for this, or those fancy things called CDNs. If your
+application is small enough that it would benefit from single-node memory
+caching, it's small enough that it does not need caching at all ;).
+
+## Debugging
+
+To enable `debug()` instrumentation output export __DEBUG__:
+
+```
+$ DEBUG=send node app
+```
+
+## Running tests
+
+```
+$ npm install
+$ npm test
+```
+
+## Examples
+
+### Small example
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname).pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Custom file types
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+// Default unknown types to text/plain
+send.mime.default_type = 'text/plain'
+
+// Add a custom type
+send.mime.define({
+  'application/x-my-type': ['x-mt', 'x-mtt']
+})
+
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname).pipe(res)
+})
+
+server.listen(3000)
+```
+
+### Custom directory index view
+
+This is a example of serving up a structure of directories with a
+custom function to render a listing of a directory.
+
+```js
+var http = require('http')
+var fs = require('fs')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+// Transfer arbitrary files from within /www/example.com/public/*
+// with a custom handler for directory listing
+var server = http.createServer(function onRequest (req, res) {
+  send(req, parseUrl(req).pathname, {index: false, root: '/www/example.com/public'})
+  .once('directory', directory)
+  .pipe(res)
+})
+
+server.listen(3000)
+
+// Custom directory handler
+function directory (res, path) {
+  var stream = this
+
+  // redirect to trailing slash for consistent url
+  if (!stream.hasTrailingSlash()) {
+    return stream.redirect(path)
+  }
+
+  // get directory list
+  fs.readdir(path, function onReaddir (err, list) {
+    if (err) return stream.error(err)
+
+    // render an index for the directory
+    res.setHeader('Content-Type', 'text/plain; charset=UTF-8')
+    res.end(list.join('\n') + '\n')
+  })
+}
+```
+
+### Serving from a root directory with custom error-handling
+
+```js
+var http = require('http')
+var parseUrl = require('parseurl')
+var send = require('send')
+
+var server = http.createServer(function onRequest (req, res) {
+  // your custom error-handling logic:
+  function error (err) {
+    res.statusCode = err.status || 500
+    res.end(err.message)
+  }
+
+  // your custom headers
+  function headers (res, path, stat) {
+    // serve all files for download
+    res.setHeader('Content-Disposition', 'attachment')
+  }
+
+  // your custom directory handling logic:
+  function redirect () {
+    res.statusCode = 301
+    res.setHeader('Location', req.url + '/')
+    res.end('Redirecting to ' + req.url + '/')
+  }
+
+  // transfer arbitrary files from within
+  // /www/example.com/public/*
+  send(req, parseUrl(req).pathname, {root: '/www/example.com/public'})
+  .on('error', error)
+  .on('directory', redirect)
+  .on('headers', headers)
+  .pipe(res)
+})
+
+server.listen(3000)
+```

+## Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install serve-static
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var serveStatic = require('serve-static')
+```
+
+### serveStatic(root, options)
+
+Create a new middleware function to serve files from within a given root
+directory. The file to serve will be determined by combining `req.url`
+with the provided root directory. When a file is not found, instead of
+sending a 404 response, this module will instead call `next()` to move on
+to the next middleware, allowing for stacking and fall-backs.
+
+#### Options
+
+##### acceptRanges
+
+Enable or disable accepting ranged requests, defaults to true.
+Disabling this will not send `Accept-Ranges` and ignore the contents
+of the `Range` request header.
+
+##### cacheControl
+
+Enable or disable setting `Cache-Control` response header, defaults to
+true. Disabling this will ignore the `immutable` and `maxAge` options.
+
+##### dotfiles
+
+ Set how "dotfiles" are treated when encountered. A dotfile is a file
+or directory that begins with a dot ("."). Note this check is done on
+the path itself without checking if the path actually exists on the
+disk. If `root` is specified, only the dotfiles above the root are
+checked (i.e. the root itself can be within a dotfile when set
+to "deny").
+
+  - `'allow'` No special treatment for dotfiles.
+  - `'deny'` Deny a request for a dotfile and 403/`next()`.
+  - `'ignore'` Pretend like the dotfile does not exist and 404/`next()`.
+
+The default value is similar to `'ignore'`, with the exception that this
+default will not ignore the files within a directory that begins with a dot.
+
+##### etag
+
+Enable or disable etag generation, defaults to true.
+
+##### extensions
+
+Set file extension fallbacks. When set, if a file is not found, the given
+extensions will be added to the file name and search for. The first that
+exists will be served. Example: `['html', 'htm']`.
+
+The default value is `false`.
+
+##### fallthrough
+
+Set the middleware to have client errors fall-through as just unhandled
+requests, otherwise forward a client error. The difference is that client
+errors like a bad request or a request to a non-existent file will cause
+this middleware to simply `next()` to your next middleware when this value
+is `true`. When this value is `false`, these errors (even 404s), will invoke
+`next(err)`.
+
+Typically `true` is desired such that multiple physical directories can be
+mapped to the same web address or for routes to fill in non-existent files.
+
+The value `false` can be used if this middleware is mounted at a path that
+is designed to be strictly a single file system directory, which allows for
+short-circuiting 404s for less overhead. This middleware will also reply to
+all methods.
+
+The default value is `true`.
+
+##### immutable
+
+Enable or diable the `immutable` directive in the `Cache-Control` response
+header, defaults to `false`. If set to `true`, the `maxAge` option should
+also be specified to enable caching. The `immutable` directive will prevent
+supported clients from making conditional requests during the life of the
+`maxAge` option to check if the file has changed.
+
+##### index
+
+By default this module will send "index.html" files in response to a request
+on a directory. To disable this set `false` or to supply a new index pass a
+string or an array in preferred order.
+
+##### lastModified
+
+Enable or disable `Last-Modified` header, defaults to true. Uses the file
+system's last modified value.
+
+##### maxAge
+
+Provide a max-age in milliseconds for http caching, defaults to 0. This
+can also be a string accepted by the [ms](https://www.npmjs.org/package/ms#readme)
+module.
+
+##### redirect
+
+Redirect to trailing "/" when the pathname is a dir. Defaults to `true`.
+
+##### setHeaders
+
+Function to set custom headers on response. Alterations to the headers need to
+occur synchronously. The function is called as `fn(res, path, stat)`, where
+the arguments are:
+
+  - `res` the response object
+  - `path` the file path that is being sent
+  - `stat` the stat object of the file that is being sent
+
+## Examples
+
+### Serve files with vanilla node.js http server
+
+```js
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+// Serve up public/ftp folder
+var serve = serveStatic('public/ftp', {'index': ['index.html', 'index.htm']})
+
+// Create server
+var server = http.createServer(function onRequest (req, res) {
+  serve(req, res, finalhandler(req, res))
+})
+
+// Listen
+server.listen(3000)
+```
+
+### Serve all files as downloads
+
+```js
+var contentDisposition = require('content-disposition')
+var finalhandler = require('finalhandler')
+var http = require('http')
+var serveStatic = require('serve-static')
+
+// Serve up public/ftp folder
+var serve = serveStatic('public/ftp', {
+  'index': false,
+  'setHeaders': setHeaders
+})
+
+// Set header to force download
+function setHeaders (res, path) {
+  res.setHeader('Content-Disposition', contentDisposition(path))
+}
+
+// Create server
+var server = http.createServer(function onRequest (req, res) {
+  serve(req, res, finalhandler(req, res))
+})
+
+// Listen
+server.listen(3000)
+```
+
+### Serving using express
+
+#### Simple
+
+This is a simple example of using Express.
+
+```js
+var express = require('express')
+var serveStatic = require('serve-static')
+
+var app = express()
+
+app.use(serveStatic('public/ftp', {'index': ['default.html', 'default.htm']}))
+app.listen(3000)
+```
+
+#### Multiple roots
+
+This example shows a simple way to search through multiple directories.
+Files are look for in `public-optimized/` first, then `public/` second as
+a fallback.
+
+```js
+var express = require('express')
+var path = require('path')
+var serveStatic = require('serve-static')
+
+var app = express()
+
+app.use(serveStatic(path.join(__dirname, 'public-optimized')))
+app.use(serveStatic(path.join(__dirname, 'public')))
+app.listen(3000)
+```
+
+#### Different settings for paths
+
+This example shows how to set a different max age depending on the served
+file type. In this example, HTML files are not cached, while everything else
+is for 1 day.
+
+```js
+var express = require('express')
+var path = require('path')
+var serveStatic = require('serve-static')
+
+var app = express()
+
+app.use(serveStatic(path.join(__dirname, 'public'), {
+  maxAge: '1d',
+  setHeaders: setCustomCacheControl
+}))
+
+app.listen(3000)
+
+function setCustomCacheControl (res, path) {
+  if (serveStatic.mime.lookup(path) === 'text/html') {
+    // Custom Cache-Control for HTML files
+    res.setHeader('Cache-Control', 'public, max-age=0')
+  }
+}
+```

+# socket.io-adapter
+
+Default socket.io in-memory adapter class.
+
+## How to use
+
+This module is not intended for end-user usage, but can be used as an
+interface to inherit from from other adapters you might want to build.
+
+As an example of an adapter that builds on top of this, please take a look
+at [socket.io-redis](https://github.com/learnboost/socket.io-redis).

+
+## How to use
+
+A standalone build of `socket.io-client` is exposed automatically by the
+socket.io server as `/socket.io/socket.io.js`. Alternatively you can
+serve the file `socket.io.js` found in the `dist` folder.
+
+```html
+<script src="/socket.io/socket.io.js"></script>
+<script>
+  var socket = io('http://localhost');
+  socket.on('connect', function(){});
+  socket.on('event', function(data){});
+  socket.on('disconnect', function(){});
+</script>
+```
+
+```js
+// with ES6 import
+import io from 'socket.io-client';
+
+const socket = io('http://localhost');
+```
+
+A slim build (without `JSON3`, a JSON polyfill for IE6/IE7, and `debug`) is also available: `socket.io.slim.js`.
+
+Socket.IO is compatible with [browserify](http://browserify.org/) and [webpack](https://webpack.js.org/) (see example [there](https://github.com/socketio/socket.io/tree/2.0.3/examples/webpack-build)).
+
+### Node.JS (server-side usage)
+
+  Add `socket.io-client` to your `package.json` and then:
+
+  ```js
+  var socket = require('socket.io-client')('http://localhost');
+  socket.on('connect', function(){});
+  socket.on('event', function(data){});
+  socket.on('disconnect', function(){});
+  ```

+[![Build Status](https://secure.travis-ci.org/socketio/socket.io-parser.svg?branch=master)](http://travis-ci.org/socketio/socket.io-parser)
+[![NPM version](https://badge.fury.io/js/socket.io-parser.svg)](http://badge.fury.io/js/socket.io-parser)
+
+A socket.io encoder and decoder written in JavaScript complying with version `3`
+of [socket.io-protocol](https://github.com/socketio/socket.io-protocol).
+Used by [socket.io](https://github.com/automattic/socket.io) and
+[socket.io-client](https://github.com/automattic/socket.io-client).
+
+## Parser API
+
+  socket.io-parser is the reference implementation of socket.io-protocol. Read
+  the full API here:
+  [socket.io-protocol](https://github.com/learnboost/socket.io-protocol).
+
+## Example Usage
+
+### Encoding and decoding a packet
+
+```js
+var parser = require('socket.io-parser');
+var encoder = new parser.Encoder();
+var packet = {
+  type: parser.EVENT,
+  data: 'test-packet',
+  id: 13
+};
+encoder.encode(packet, function(encodedPackets) {
+  var decoder = new parser.Decoder();
+  decoder.on('decoded', function(decodedPacket) {
+    // decodedPacket.type == parser.EVENT
+    // decodedPacket.data == 'test-packet'
+    // decodedPacket.id == 13
+  });

+
+## Features
+
+Socket.IO enables real-time bidirectional event-based communication. It consists in:
+
+- a Node.js server (this repository)
+- a [Javascript client library](https://github.com/socketio/socket.io-client) for the browser (or a Node.js client)
+
+Some implementations in other languages are also available:
+
+- [Java](https://github.com/socketio/socket.io-client-java)
+- [C++](https://github.com/socketio/socket.io-client-cpp)
+- [Swift](https://github.com/socketio/socket.io-client-swift)
+
+Its main features are:
+
+#### Reliability
+
+Connections are established even in the presence of:
+  - proxies and load balancers.
+  - personal firewall and antivirus software.
+
+For this purpose, it relies on [Engine.IO](https://github.com/socketio/engine.io), which first establishes a long-polling connection, then tries to upgrade to better transports that are "tested" on the side, like WebSocket. Please see the [Goals](https://github.com/socketio/engine.io#goals) section for more information.
+
+#### Auto-reconnection support
+
+Unless instructed otherwise a disconnected client will try to reconnect forever, until the server is available again. Please see the available reconnection options [here](https://github.com/socketio/socket.io-client/blob/master/docs/API.md#new-managerurl-options).
+
+#### Disconnection detection
+
+An heartbeat mechanism is implemented at the Engine.IO level, allowing both the server and the client to know when the other one is not responding anymore.
+
+That functionality is achieved with timers set on both the server and the client, with timeout values (the `pingInterval` and `pingTimeout` parameters) shared during the connection handshake. Those timers require any subsequent client calls to be directed to the same server, hence the `sticky-session` requirement when using multiples nodes.
+
+#### Binary support
+
+Any serializable data structures can be emitted, including:
+
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Blob](https://developer.mozilla.org/en-US/docs/Web/API/Blob) in the browser
+- [ArrayBuffer](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/ArrayBuffer) and [Buffer](https://nodejs.org/api/buffer.html) in Node.js
+
+#### Simple and convenient API
+
+Sample code:
+
+```js
+io.on('connection', function(socket){
+  socket.emit('request', /* */); // emit an event to the socket
+  io.emit('broadcast', /* */); // emit an event to all connected sockets
+  socket.on('reply', function(){ /* */ }); // listen to the event
+});
+```
+
+#### Cross-browser
+
+Browser support is tested in Saucelabs:
+
+[![Sauce Test Status](https://saucelabs.com/browser-matrix/socket.svg)](https://saucelabs.com/u/socket)
+
+#### Multiplexing support
+
+In order to create separation of concerns within your application (for example per module, or based on permissions), Socket.IO allows you to create several `Namespaces`, which will act as separate communication channels but will share the same underlying connection.
+
+#### Room support
+
+Within each `Namespace`, you can define arbitrary channels, called `Rooms`, that sockets can join and leave. You can then broadcast to any given room, reaching every socket that has joined it.
+
+This is a useful feature to send notifications to a group of users, or to a given user connected on several devices for example.
+
+
+**Note:** Socket.IO is not a WebSocket implementation. Although Socket.IO indeed uses WebSocket as a transport when possible, it adds some metadata to each packet: the packet type, the namespace and the ack id when a message acknowledgement is needed. That is why a WebSocket client will not be able to successfully connect to a Socket.IO server, and a Socket.IO client will not be able to connect to a WebSocket server (like `ws://echo.websocket.org`) either. Please see the protocol specification [here](https://github.com/socketio/socket.io-protocol).
+
+## Installation
+
+```bash
+npm install socket.io --save
+```
+
+## How to use
+
+The following example attaches socket.io to a plain Node.JS
+HTTP server listening on port `3000`.
+
+```js
+var server = require('http').createServer();
+var io = require('socket.io')(server);
+io.on('connection', function(client){
+  client.on('event', function(data){});
+  client.on('disconnect', function(){});
+});
+server.listen(3000);
+```
+
+### Standalone
+
+```js
+var io = require('socket.io')();
+io.on('connection', function(client){});
+io.listen(3000);
+```
+
+### In conjunction with Express
+
+Starting with **3.0**, express applications have become request handler
+functions that you pass to `http` or `http` `Server` instances. You need
+to pass the `Server` to `socket.io`, and not the express application
+function. Also make sure to call `.listen` on the `server`, not the `app`.
+
+```js
+var app = require('express')();
+var server = require('http').createServer(app);
+var io = require('socket.io')(server);
+io.on('connection', function(){ /* … */ });
+server.listen(3000);
+```
+
+### In conjunction with Koa
+
+Like Express.JS, Koa works by exposing an application as a request
+handler function, but only by calling the `callback` method.
+
+```js
+var app = require('koa')();
+var server = require('http').createServer(app.callback());
+var io = require('socket.io')(server);
+io.on('connection', function(){ /* … */ });
+server.listen(3000);
+```
+
+## Documentation
+
+Please see the documentation [here](/docs/README.md). Contributions are welcome!
+
+## Debug / logging
+
+Socket.IO is powered by [debug](https://github.com/visionmedia/debug).
+In order to see all the debug output, run your app with the environment variable
+`DEBUG` including the desired scope.
+
+To see the output from all of Socket.IO's debugging scopes you can use:
+
+```
+DEBUG=socket.io* node myapp
+```
+
+## Testing
+
+```
+npm test
+```
+This runs the `gulp` task `test`. By default the test will be run with the source code in `lib` directory.
+
+Set the environmental variable `TEST_VERSION` to `compat` to test the transpiled es5-compat version of the code.
+
+The `gulp` task `test` will always transpile the source code into es5 and export to `dist` first before running the test.

+
+HTTP status utility for node.
+
+## API
+
+```js
+var status = require('statuses')
+```
+
+### var code = status(Integer || String)
+
+If `Integer` or `String` is a valid HTTP code or status message, then the appropriate `code` will be returned. Otherwise, an error will be thrown.
+
+```js
+status(403) // => 403
+status('403') // => 403
+status('forbidden') // => 403
+status('Forbidden') // => 403
+status(306) // throws, as it's not supported by node.js
+```
+
+### status.codes
+
+Returns an array of all the status codes as `Integer`s.
+
+### var msg = status[code]
+
+Map of `code` to `status message`. `undefined` for invalid `code`s.
+
+```js
+status[404] // => 'Not Found'
+```
+
+### var code = status[msg]
+
+Map of `status message` to `code`. `msg` can either be title-cased or lower-cased. `undefined` for invalid `status message`s.
+
+```js
+status['not found'] // => 404
+status['Not Found'] // => 404
+```
+
+### status.redirect[code]
+
+Returns `true` if a status code is a valid redirect status.
+
+```js
+status.redirect[200] // => undefined
+status.redirect[301] // => true
+```
+
+### status.empty[code]
+
+Returns `true` if a status code expects an empty body.
+
+```js
+status.empty[200] // => undefined
+status.empty[204] // => true
+status.empty[304] // => true
+```
+
+### status.retry[code]
+
+Returns `true` if you should retry the rest.
+
+```js
+status.retry[501] // => undefined
+status.retry[503] // => true
+```
+
+## Adding Status Codes
+
+The status codes are primarily sourced from http://www.iana.org/assignments/http-status-codes/http-status-codes-1.csv.
+Additionally, custom codes are added from http://en.wikipedia.org/wiki/List_of_HTTP_status_codes.
+These are added manually in the `lib/*.json` files.
+If you would like to add a status code, add it to the appropriate JSON file.
+
+To rebuild `codes.json`, run the following:
+
+```bash
+# update src/iana.json
+npm run fetch
+# build codes.json
+npm run build
+```

+
+Infer the content-type of a request.
+
+### Install
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
+
+```sh
+$ npm install type-is
+```
+
+## API
+
+```js
+var http = require('http')
+var typeis = require('type-is')
+
+http.createServer(function (req, res) {
+  var istext = typeis(req, ['text/*'])
+  res.end('you ' + (istext ? 'sent' : 'did not send') + ' me text')
+})
+```
+
+### type = typeis(request, types)
+
+`request` is the node HTTP request. `types` is an array of types.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// req.headers.content-type = 'application/json'
+
+typeis(req, ['json'])             // 'json'
+typeis(req, ['html', 'json'])     // 'json'
+typeis(req, ['application/*'])    // 'application/json'
+typeis(req, ['application/json']) // 'application/json'
+
+typeis(req, ['html']) // false
+```
+
+### typeis.hasBody(request)
+
+Returns a Boolean if the given `request` has a body, regardless of the
+`Content-Type` header.
+
+Having a body has no relation to how large the body is (it may be 0 bytes).
+This is similar to how file existence works. If a body does exist, then this
+indicates that there is data to read from the Node.js request stream.
+
+<!-- eslint-disable no-undef -->
+
+```js
+if (typeis.hasBody(req)) {
+  // read the body, since there is one
+
+  req.on('data', function (chunk) {
+    // ...
+  })
+}
+```
+
+### type = typeis.is(mediaType, types)
+
+`mediaType` is the [media type](https://tools.ietf.org/html/rfc6838) string. `types` is an array of types.
+
+<!-- eslint-disable no-undef -->
+
+```js
+var mediaType = 'application/json'
+
+typeis.is(mediaType, ['json'])             // 'json'
+typeis.is(mediaType, ['html', 'json'])     // 'json'
+typeis.is(mediaType, ['application/*'])    // 'application/json'
+typeis.is(mediaType, ['application/json']) // 'application/json'
+
+typeis.is(mediaType, ['html']) // false
+```
+
+### Each type can be:
+
+- An extension name such as `json`. This name will be returned if matched.
+- A mime type such as `application/json`.
+- A mime type with a wildcard such as `*/*` or `*/json` or `application/*`. The full mime type will be returned if matched.
+- A suffix such as `+json`. This can be combined with a wildcard such as `*/vnd+json` or `application/*+json`. The full mime type will be returned if matched.
+
+`false` will be returned if no type matches or the content type is invalid.
+
+`null` will be returned if the request does not have a body.
+
+## Examples
+
+### Example body parser
+
+```js
+var express = require('express')
+var typeis = require('type-is')
+
+var app = express()
+
+app.use(function bodyParser (req, res, next) {
+  if (!typeis.hasBody(req)) {
+    return next()
+  }
+
+  switch (typeis(req, ['urlencoded', 'json', 'multipart'])) {
+    case 'urlencoded':
+      // parse urlencoded body
+      throw new Error('implement urlencoded body parsing')
+    case 'json':
+      // parse json body
+      throw new Error('implement json body parsing')
+    case 'multipart':
+      // parse multipart body
+      throw new Error('implement multipart body parsing')
+    default:
+      // 415 error code
+      res.statusCode = 415
+      res.end()
+      break
+  }
+})
+```

+Unpipe a stream from all destinations.
+
+## Installation
+
+```sh
+$ npm install unpipe
+```
+
+## API
+
+```js
+var unpipe = require('unpipe')
+```
+
+### unpipe(stream)
+
+Unpipes all destinations from a given stream. With stream 2+, this is
+equivalent to `stream.unpipe()`. When used with streams 1 style streams
+(typically Node.js 0.8 and below), this module attempts to undo the
+actions done in `stream.pipe(dest)`.

+## Usage
+`uws` tries to mimic `ws` as closely as possible without sacrificing too much performance. In most cases you simply swap `require('ws')` with `require('uws')`:
+
+```javascript
+var WebSocketServer = require('uws').Server;
+var wss = new WebSocketServer({ port: 3000 });
+
+function onMessage(message) {
+    console.log('received: ' + message);
+}
+
+wss.on('connection', function(ws) {
+    ws.on('message', onMessage);
+    ws.send('something');
+});
+```
+
+##### Deviations from ws
+There are some important incompatibilities with `ws` though, we aim to be ~90% compatible but will never implement behavior that is deemed too inefficient:
+
+* Binary data is passed zero-copy as an `ArrayBuffer`. This means you need to copy it to keep it past the callback. It also means you need to convert it with `Buffer.from(message)` if you expect a `Node.js Buffer`.
+* `webSocket._socket` is not a `net.Socket`, it is just a getter function with very basic functionalities.
+* `webSocket._socket.remote...` might fail, you need to cache it at connection.
+* `webSocket` acts like an `EventEmitter` with one listener per event maximum.
+* `webSocket.upgradeReq` is only valid during execution of the connection handler. If you want to keep properties of the upgradeReq for the entire lifetime of the webSocket you better attach that specific property to the webSocket at connection.
+
+## Installation
+[![](https://nodei.co/npm/uws.png)](https://www.npmjs.com/package/uws)
+
+At installation `uws` will try to recompile itself using the system's C++11 compiler (GCC 4.8+, Clang 3.3, VC++ 2015+).
+If this fails it will silently fall back to using the precompiled binaries.
+NPM installation will never fail but `require('uws')` will throw if it cannot properly load the binary module.

+
+Manipulate the HTTP Vary header
+
+## Installation
+
+This is a [Node.js](https://nodejs.org/en/) module available through the
+[npm registry](https://www.npmjs.com/). Installation is done using the
+[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): 
+
+```sh
+$ npm install vary
+```
+
+## API
+
+<!-- eslint-disable no-unused-vars -->
+
+```js
+var vary = require('vary')
+```
+
+### vary(res, field)
+
+Adds the given header `field` to the `Vary` response header of `res`.
+This can be a string of a single field, a string of a valid `Vary`
+header, or an array of multiple fields.
+
+This will append the header if not already listed, otherwise leaves
+it listed in the current location.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// Append "Origin" to the Vary header of the response
+vary(res, 'Origin')
+```
+
+### vary.append(header, field)
+
+Adds the given header `field` to the `Vary` response header string `header`.
+This can be a string of a single field, a string of a valid `Vary` header,
+or an array of multiple fields.
+
+This will append the header if not already listed, otherwise leaves
+it listed in the current location. The new header string is returned.
+
+<!-- eslint-disable no-undef -->
+
+```js
+// Get header string appending "Origin" to "Accept, User-Agent"
+vary.append('Accept, User-Agent', 'Origin')
+```
+
+## Examples
+
+### Updating the Vary header when content is based on it
+
+```js
+var http = require('http')
+var vary = require('vary')
+
+http.createServer(function onRequest (req, res) {
+  // about to user-agent sniff
+  vary(res, 'User-Agent')
+
+  var ua = req.headers['user-agent'] || ''
+  var isMobile = /mobi|android|touch|mini/i.test(ua)
+
+  // serve site, depending on isMobile
+  res.setHeader('Content-Type', 'text/html')
+  res.end('You are (probably) ' + (isMobile ? '' : 'not ') + 'a mobile user')
+})
+```
+
+## Testing
+
+```sh
+$ npm test
+```

+# ws: a Node.js WebSocket library
+
+[![Version npm](https://img.shields.io/npm/v/ws.svg)](https://www.npmjs.com/package/ws)
+[![Linux Build](https://img.shields.io/travis/websockets/ws/master.svg)](https://travis-ci.org/websockets/ws)
+[![Windows Build](https://ci.appveyor.com/api/projects/status/github/websockets/ws?branch=master&svg=true)](https://ci.appveyor.com/project/lpinca/ws)
+[![Coverage Status](https://img.shields.io/coveralls/websockets/ws/master.svg)](https://coveralls.io/r/websockets/ws?branch=master)
+
+`ws` is a simple to use, blazing fast, and thoroughly tested WebSocket client
+and server implementation.
+
+Passes the quite extensive Autobahn test suite. See http://websockets.github.io/ws/
+for the full reports.
+
+**Note**: This module does not work in the browser. The client in the docs is a
+reference to a back end with the role of a client in the WebSocket
+communication. Browser clients must use the native
+[`WebSocket`](https://developer.mozilla.org/en-US/docs/Web/API/WebSocket) object.
+
+## Protocol support
+
+* **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
+* **HyBi drafts 13-17** (Current default, alternatively option `protocolVersion: 13`)
+
+## Installing
+
+```
+npm install --save ws
+```
+
+### Opt-in for performance and spec compliance
+
+There are 2 optional modules that can be installed along side with the `ws`
+module. These modules are binary addons which improve certain operations.
+Prebuilt binaries are available for the most popular platforms so you don't
+necessarily need to have a C++ compiler installed on your machine.
+
+- `npm install --save-optional bufferutil`: Allows to efficiently perform
+  operations such as masking and unmasking the data payload of the WebSocket
+  frames.
+- `npm install --save-optional utf-8-validate`: Allows to efficiently check
+  if a message contains valid UTF-8 as required by the spec.
+
+## API Docs
+
+See [`/doc/ws.md`](https://github.com/websockets/ws/blob/master/doc/ws.md)
+for Node.js-like docs for the ws classes.
+
+## WebSocket compression
+
+`ws` supports the [permessage-deflate extension][permessage-deflate] which
+enables the client and server to negotiate a compression algorithm and its
+parameters, and then selectively apply it to the data payloads of each
+WebSocket message.
+
+The extension is enabled by default but adds a significant overhead in terms of
+performance and memory comsumption. We suggest to use WebSocket compression
+only if it is really needed.
+
+To disable the extension you can set the `perMessageDeflate` option to `false`.
+On the server:
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({
+  perMessageDeflate: false,
+  port: 8080
+});
+```
+
+On the client:
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path', {
+  perMessageDeflate: false
+});
+```
+
+## Usage examples
+
+### Sending and receiving text data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  ws.send('something');
+});
+
+ws.on('message', function incoming(data, flags) {
+  // flags.binary will be set if a binary data is received.
+  // flags.masked will be set if the data was masked.
+});
+```
+
+### Sending binary data
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('ws://www.host.com/path');
+
+ws.on('open', function open() {
+  const array = new Float32Array(5);
+
+  for (var i = 0; i < array.length; ++i) {
+    array[i] = i / 2;
+  }
+
+  ws.send(array);
+});
+```
+
+### Server example
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+```
+
+### Broadcast example
+
+```js
+const WebSocket = require('ws');
+
+const wss = new WebSocket.Server({ port: 8080 });
+
+// Broadcast to all.
+wss.broadcast = function broadcast(data) {
+  wss.clients.forEach(function each(client) {
+    if (client.readyState === WebSocket.OPEN) {
+      client.send(data);
+    }
+  });
+};
+
+wss.on('connection', function connection(ws) {
+  ws.on('message', function incoming(data) {
+    // Broadcast to everyone else.
+    wss.clients.forEach(function each(client) {
+      if (client !== ws && client.readyState === WebSocket.OPEN) {
+        client.send(data);
+      }
+    });
+  });
+});
+```
+
+### ExpressJS example
+
+```js
+const express = require('express');
+const http = require('http');
+const url = require('url');
+const WebSocket = require('ws');
+
+const app = express();
+
+app.use(function (req, res) {
+  res.send({ msg: "hello" });
+});
+
+const server = http.createServer(app);
+const wss = new WebSocket.Server({ server });
+
+wss.on('connection', function connection(ws) {
+  const location = url.parse(ws.upgradeReq.url, true);
+  // You might use location.query.access_token to authenticate or share sessions
+  // or ws.upgradeReq.headers.cookie (see http://stackoverflow.com/a/16395220/151312)
+
+  ws.on('message', function incoming(message) {
+    console.log('received: %s', message);
+  });
+
+  ws.send('something');
+});
+
+server.listen(8080, function listening() {
+  console.log('Listening on %d', server.address().port);
+});
+```
+
+### echo.websocket.org demo
+
+```js
+const WebSocket = require('ws');
+
+const ws = new WebSocket('wss://echo.websocket.org/', {
+  origin: 'https://websocket.org'
+});
+
+ws.on('open', function open() {
+  console.log('connected');
+  ws.send(Date.now());
+});
+
+ws.on('close', function close() {
+  console.log('disconnected');
+});
+
+ws.on('message', function incoming(data, flags) {
+  console.log(`Roundtrip time: ${Date.now() - data} ms`, flags);
+
+  setTimeout(function timeout() {
+    ws.send(Date.now());
+  }, 500);
+});
+```
+
+### Other examples
+
+For a full example with a browser client communicating with a ws server, see the
+examples folder.
+
+Otherwise, see the test cases.
+
+## Error handling best practices
+
+```js
+// If the WebSocket is closed before the following send is attempted
+ws.send('something');
+
+// Errors (both immediate and async write errors) can be detected in an optional
+// callback. The callback is also the only way of being notified that data has
+// actually been sent.
+ws.send('something', function ack(error) {
+  // If error is not defined, the send has been completed, otherwise the error
+  // object will indicate what failed.
+});
+
+// Immediate errors can also be handled with `try...catch`, but **note** that
+// since sends are inherently asynchronous, socket write failures will *not* be
+// captured when this technique is used.
+try { ws.send('something'); }
+catch (e) { /* handle error */ }
+```

+#### Safer Node.js Buffer API
+
+**Use the new Node.js v6 Buffer APIs (`Buffer.from`, `Buffer.alloc`,
+`Buffer.allocUnsafe`, `Buffer.allocUnsafeSlow`) in Node.js v0.10, v0.12, v4.x, and v5.x.**
+
+**Uses the built-in implementations when available.**

+
+## install
+
+```
+npm install safe-buffer
+```
+
+## usage
+
+The goal of this package is to provide a safe replacement for the node.js `Buffer`.
+
+It's a drop-in replacement for `Buffer`. You can use it by adding one `require` line to
+the top of your node.js modules:
+
+```js
+var Buffer = require('safe-buffer').Buffer
+
+// Existing buffer code will continue to work without issues:
+
+new Buffer('hey', 'utf8')
+new Buffer([1, 2, 3], 'utf8')
+new Buffer(obj)
+new Buffer(16) // create an uninitialized buffer (potentially unsafe)
+
+// But you can use these new explicit APIs to make clear what you want:
+
+Buffer.from('hey', 'utf8') // convert from many types to a Buffer
+Buffer.alloc(16) // create a zero-filled buffer (safe)
+Buffer.allocUnsafe(16) // create an uninitialized buffer (potentially unsafe)
+```
+
+## api
+
+### Class Method: Buffer.from(array)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `array` {Array}
+
+Allocates a new `Buffer` using an `array` of octets.
+
+```js
+const buf = Buffer.from([0x62,0x75,0x66,0x66,0x65,0x72]);
+  // creates a new Buffer containing ASCII bytes
+  // ['b','u','f','f','e','r']
+```
+
+A `TypeError` will be thrown if `array` is not an `Array`.
+
+### Class Method: Buffer.from(arrayBuffer[, byteOffset[, length]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `arrayBuffer` {ArrayBuffer} The `.buffer` property of a `TypedArray` or
+  a `new ArrayBuffer()`
+* `byteOffset` {Number} Default: `0`
+* `length` {Number} Default: `arrayBuffer.length - byteOffset`
+
+When passed a reference to the `.buffer` property of a `TypedArray` instance,
+the newly created `Buffer` will share the same allocated memory as the
+TypedArray.
+
+```js
+const arr = new Uint16Array(2);
+arr[0] = 5000;
+arr[1] = 4000;
+
+const buf = Buffer.from(arr.buffer); // shares the memory with arr;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 a0 0f>
+
+// changing the TypedArray changes the Buffer also
+arr[1] = 6000;
+
+console.log(buf);
+  // Prints: <Buffer 88 13 70 17>
+```
+
+The optional `byteOffset` and `length` arguments specify a memory range within
+the `arrayBuffer` that will be shared by the `Buffer`.
+
+```js
+const ab = new ArrayBuffer(10);
+const buf = Buffer.from(ab, 0, 2);
+console.log(buf.length);
+  // Prints: 2
+```
+
+A `TypeError` will be thrown if `arrayBuffer` is not an `ArrayBuffer`.
+
+### Class Method: Buffer.from(buffer)
+<!-- YAML
+added: v3.0.0
+-->
+
+* `buffer` {Buffer}
+
+Copies the passed `buffer` data onto a new `Buffer` instance.
+
+```js
+const buf1 = Buffer.from('buffer');
+const buf2 = Buffer.from(buf1);
+
+buf1[0] = 0x61;
+console.log(buf1.toString());
+  // 'auffer'
+console.log(buf2.toString());
+  // 'buffer' (copy is not changed)
+```
+
+A `TypeError` will be thrown if `buffer` is not a `Buffer`.
+
+### Class Method: Buffer.from(str[, encoding])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `str` {String} String to encode.
+* `encoding` {String} Encoding to use, Default: `'utf8'`
+
+Creates a new `Buffer` containing the given JavaScript string `str`. If
+provided, the `encoding` parameter identifies the character encoding.
+If not provided, `encoding` defaults to `'utf8'`.
+
+```js
+const buf1 = Buffer.from('this is a tést');
+console.log(buf1.toString());
+  // prints: this is a tést
+console.log(buf1.toString('ascii'));
+  // prints: this is a tC)st
+
+const buf2 = Buffer.from('7468697320697320612074c3a97374', 'hex');
+console.log(buf2.toString());
+  // prints: this is a tést
+```
+
+A `TypeError` will be thrown if `str` is not a string.
+
+### Class Method: Buffer.alloc(size[, fill[, encoding]])
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+* `fill` {Value} Default: `undefined`
+* `encoding` {String} Default: `utf8`
+
+Allocates a new `Buffer` of `size` bytes. If `fill` is `undefined`, the
+`Buffer` will be *zero-filled*.
+
+```js
+const buf = Buffer.alloc(5);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+The `size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+If `fill` is specified, the allocated `Buffer` will be initialized by calling
+`buf.fill(fill)`. See [`buf.fill()`][] for more information.
+
+```js
+const buf = Buffer.alloc(5, 'a');
+console.log(buf);
+  // <Buffer 61 61 61 61 61>
+```
+
+If both `fill` and `encoding` are specified, the allocated `Buffer` will be
+initialized by calling `buf.fill(fill, encoding)`. For example:
+
+```js
+const buf = Buffer.alloc(11, 'aGVsbG8gd29ybGQ=', 'base64');
+console.log(buf);
+  // <Buffer 68 65 6c 6c 6f 20 77 6f 72 6c 64>
+```
+
+Calling `Buffer.alloc(size)` can be significantly slower than the alternative
+`Buffer.allocUnsafe(size)` but ensures that the newly created `Buffer` instance
+contents will *never contain sensitive data*.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### Class Method: Buffer.allocUnsafe(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* `Buffer` of `size` bytes.  The `size` must
+be less than or equal to the value of `require('buffer').kMaxLength` (on 64-bit
+architectures, `kMaxLength` is `(2^31)-1`). Otherwise, a [`RangeError`][] is
+thrown. A zero-length Buffer will be created if a `size` less than or equal to
+0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+```js
+const buf = Buffer.allocUnsafe(5);
+console.log(buf);
+  // <Buffer 78 e0 82 02 01>
+  // (octets will be different, every time)
+buf.fill(0);
+console.log(buf);
+  // <Buffer 00 00 00 00 00>
+```
+
+A `TypeError` will be thrown if `size` is not a number.
+
+Note that the `Buffer` module pre-allocates an internal `Buffer` instance of
+size `Buffer.poolSize` that is used as a pool for the fast allocation of new
+`Buffer` instances created using `Buffer.allocUnsafe(size)` (and the deprecated
+`new Buffer(size)` constructor) only when `size` is less than or equal to
+`Buffer.poolSize >> 1` (floor of `Buffer.poolSize` divided by two). The default
+value of `Buffer.poolSize` is `8192` but can be modified.
+
+Use of this pre-allocated internal memory pool is a key difference between
+calling `Buffer.alloc(size, fill)` vs. `Buffer.allocUnsafe(size).fill(fill)`.
+Specifically, `Buffer.alloc(size, fill)` will *never* use the internal Buffer
+pool, while `Buffer.allocUnsafe(size).fill(fill)` *will* use the internal
+Buffer pool if `size` is less than or equal to half `Buffer.poolSize`. The
+difference is subtle but can be important when an application requires the
+additional performance that `Buffer.allocUnsafe(size)` provides.
+
+### Class Method: Buffer.allocUnsafeSlow(size)
+<!-- YAML
+added: v5.10.0
+-->
+
+* `size` {Number}
+
+Allocates a new *non-zero-filled* and non-pooled `Buffer` of `size` bytes.  The
+`size` must be less than or equal to the value of
+`require('buffer').kMaxLength` (on 64-bit architectures, `kMaxLength` is
+`(2^31)-1`). Otherwise, a [`RangeError`][] is thrown. A zero-length Buffer will
+be created if a `size` less than or equal to 0 is specified.
+
+The underlying memory for `Buffer` instances created in this way is *not
+initialized*. The contents of the newly created `Buffer` are unknown and
+*may contain sensitive data*. Use [`buf.fill(0)`][] to initialize such
+`Buffer` instances to zeroes.
+
+When using `Buffer.allocUnsafe()` to allocate new `Buffer` instances,
+allocations under 4KB are, by default, sliced from a single pre-allocated
+`Buffer`. This allows applications to avoid the garbage collection overhead of
+creating many individually allocated Buffers. This approach improves both
+performance and memory usage by eliminating the need to track and cleanup as
+many `Persistent` objects.
+
+However, in the case where a developer may need to retain a small chunk of
+memory from a pool for an indeterminate amount of time, it may be appropriate
+to create an un-pooled Buffer instance using `Buffer.allocUnsafeSlow()` then
+copy out the relevant bits.
+
+```js
+// need to keep around a few small chunks of memory
+const store = [];
+
+socket.on('readable', () => {
+  const data = socket.read();
+  // allocate for retained data
+  const sb = Buffer.allocUnsafeSlow(10);
+  // copy the data into the new allocation
+  data.copy(sb, 0, 0, 10);
+  store.push(sb);
+});
+```
+
+Use of `Buffer.allocUnsafeSlow()` should be used only as a last resort *after*
+a developer has observed undue memory retention in their applications.
+
+A `TypeError` will be thrown if `size` is not a number.
+
+### All the Rest
+
+The rest of the `Buffer` API is exactly the same as in node.js.
+[See the docs](https://nodejs.org/api/buffer.html).
+
+
+## Related links
+
+- [Node.js issue: Buffer(number) is unsafe](https://github.com/nodejs/node/issues/4660)
+- [Node.js Enhancement Proposal: Buffer.from/Buffer.alloc/Buffer.zalloc/Buffer() soft-deprecate](https://github.com/nodejs/node-eps/pull/4)
+
+## Why is `Buffer` unsafe?
+
+Today, the node.js `Buffer` constructor is overloaded to handle many different argument
+types like `String`, `Array`, `Object`, `TypedArrayView` (`Uint8Array`, etc.),
+`ArrayBuffer`, and also `Number`.
+
+The API is optimized for convenience: you can throw any type at it, and it will try to do
+what you want.
+
+Because the Buffer constructor is so powerful, you often see code like this:
+
+```js
+// Convert UTF-8 strings to hex
+function toHex (str) {
+  return new Buffer(str).toString('hex')
+}
+```
+
+***But what happens if `toHex` is called with a `Number` argument?***
+
+### Remote Memory Disclosure
+
+If an attacker can make your program call the `Buffer` constructor with a `Number`
+argument, then they can make it allocate uninitialized memory from the node.js process.
+This could potentially disclose TLS private keys, user data, or database passwords.
+
+When the `Buffer` constructor is passed a `Number` argument, it returns an
+**UNINITIALIZED** block of memory of the specified `size`. When you create a `Buffer` like
+this, you **MUST** overwrite the contents before returning it to the user.
+
+From the [node.js docs](https://nodejs.org/api/buffer.html#buffer_new_buffer_size):
+
+> `new Buffer(size)`
+>
+> - `size` Number
+>
+> The underlying memory for `Buffer` instances created in this way is not initialized.
+> **The contents of a newly created `Buffer` are unknown and could contain sensitive
+> data.** Use `buf.fill(0)` to initialize a Buffer to zeroes.
+
+(Emphasis our own.)
+
+Whenever the programmer intended to create an uninitialized `Buffer` you often see code
+like this:
+
+```js
+var buf = new Buffer(16)
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### Would this ever be a problem in real code?
+
+Yes. It's surprisingly common to forget to check the type of your variables in a
+dynamically-typed language like JavaScript.
+
+Usually the consequences of assuming the wrong type is that your program crashes with an
+uncaught exception. But the failure mode for forgetting to check the type of arguments to
+the `Buffer` constructor is more catastrophic.
+
+Here's an example of a vulnerable service that takes a JSON payload and converts it to
+hex:
+
+```js
+// Take a JSON payload {str: "some string"} and convert it to hex
+var server = http.createServer(function (req, res) {
+  var data = ''
+  req.setEncoding('utf8')
+  req.on('data', function (chunk) {
+    data += chunk
+  })
+  req.on('end', function () {
+    var body = JSON.parse(data)
+    res.end(new Buffer(body.str).toString('hex'))
+  })
+})
+
+server.listen(8080)
+```
+
+In this example, an http client just has to send:
+
+```json
+{
+  "str": 1000
+}
+```
+
+and it will get back 1,000 bytes of uninitialized memory from the server.
+
+This is a very serious bug. It's similar in severity to the
+[the Heartbleed bug](http://heartbleed.com/) that allowed disclosure of OpenSSL process
+memory by remote attackers.
+
+
+### Which real-world packages were vulnerable?
+
+#### [`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht)
+
+[Mathias Buus](https://github.com/mafintosh) and I
+([Feross Aboukhadijeh](http://feross.org/)) found this issue in one of our own packages,
+[`bittorrent-dht`](https://www.npmjs.com/package/bittorrent-dht). The bug would allow
+anyone on the internet to send a series of messages to a user of `bittorrent-dht` and get
+them to reveal 20 bytes at a time of uninitialized memory from the node.js process.
+
+Here's
+[the commit](https://github.com/feross/bittorrent-dht/commit/6c7da04025d5633699800a99ec3fbadf70ad35b8)
+that fixed it. We released a new fixed version, created a
+[Node Security Project disclosure](https://nodesecurity.io/advisories/68), and deprecated all
+vulnerable versions on npm so users will get a warning to upgrade to a newer version.
+
+#### [`ws`](https://www.npmjs.com/package/ws)
+
+That got us wondering if there were other vulnerable packages. Sure enough, within a short
+period of time, we found the same issue in [`ws`](https://www.npmjs.com/package/ws), the
+most popular WebSocket implementation in node.js.
+
+If certain APIs were called with `Number` parameters instead of `String` or `Buffer` as
+expected, then uninitialized server memory would be disclosed to the remote peer.
+
+These were the vulnerable methods:
+
+```js
+socket.send(number)
+socket.ping(number)
+socket.pong(number)
+```
+
+Here's a vulnerable socket server with some echo functionality:
+
+```js
+server.on('connection', function (socket) {
+  socket.on('message', function (message) {
+    message = JSON.parse(message)
+    if (message.type === 'echo') {
+      socket.send(message.data) // send back the user's message
+    }
+  })
+})
+```
+
+`socket.send(number)` called on the server, will disclose server memory.
+
+Here's [the release](https://github.com/websockets/ws/releases/tag/1.0.1) where the issue
+was fixed, with a more detailed explanation. Props to
+[Arnout Kazemier](https://github.com/3rd-Eden) for the quick fix. Here's the
+[Node Security Project disclosure](https://nodesecurity.io/advisories/67).
+
+
+### What's the solution?
+
+It's important that node.js offers a fast way to get memory otherwise performance-critical
+applications would needlessly get a lot slower.
+
+But we need a better way to *signal our intent* as programmers. **When we want
+uninitialized memory, we should request it explicitly.**
+
+Sensitive functionality should not be packed into a developer-friendly API that loosely
+accepts many different types. This type of API encourages the lazy practice of passing
+variables in without checking the type very carefully.
+
+#### A new API: `Buffer.allocUnsafe(number)`
+
+The functionality of creating buffers with uninitialized memory should be part of another
+API. We propose `Buffer.allocUnsafe(number)`. This way, it's not part of an API that
+frequently gets user input of all sorts of different types passed into it.
+
+```js
+var buf = Buffer.allocUnsafe(16) // careful, uninitialized memory!
+
+// Immediately overwrite the uninitialized buffer with data from another buffer
+for (var i = 0; i < buf.length; i++) {
+  buf[i] = otherBuf[i]
+}
+```
+
+
+### How do we fix node.js core?
+
+We sent [a PR to node.js core](https://github.com/nodejs/node/pull/4514) (merged as
+`semver-major`) which defends against one case:
+
+```js
+var str = 16
+new Buffer(str, 'utf8')
+```
+
+In this situation, it's implied that the programmer intended the first argument to be a
+string, since they passed an encoding as a second argument. Today, node.js will allocate
+uninitialized memory in the case of `new Buffer(number, encoding)`, which is probably not
+what the programmer intended.
+
+But this is only a partial solution, since if the programmer does `new Buffer(variable)`
+(without an `encoding` parameter) there's no way to know what they intended. If `variable`
+is sometimes a number, then uninitialized memory will sometimes be returned.
+
+### What's the real long-term fix?
+
+We could deprecate and remove `new Buffer(number)` and use `Buffer.allocUnsafe(number)` when
+we need uninitialized memory. But that would break 1000s of packages.
+
+~~We believe the best solution is to:~~
+
+~~1. Change `new Buffer(number)` to return safe, zeroed-out memory~~
+
+~~2. Create a new API for creating uninitialized Buffers. We propose: `Buffer.allocUnsafe(number)`~~
+
+#### Update
+
+We now support adding three new APIs:
+
+- `Buffer.from(value)` - convert from any type to a buffer
+- `Buffer.alloc(size)` - create a zero-filled buffer
+- `Buffer.allocUnsafe(size)` - create an uninitialized buffer with given size
+
+This solves the core problem that affected `ws` and `bittorrent-dht` which is
+`Buffer(variable)` getting tricked into taking a number argument.
+
+This way, existing code continues working and the impact on the npm ecosystem will be
+minimal. Over time, npm maintainers can migrate performance-critical code to use
+`Buffer.allocUnsafe(number)` instead of `new Buffer(number)`.
+
+
+### Conclusion
+
+We think there's a serious design issue with the `Buffer` API as it exists today. It
+promotes insecure software by putting high-risk functionality into a convenient API
+with friendly "developer ergonomics".
+
+This wasn't merely a theoretical exercise because we found the issue in some of the
+most popular npm packages.
+
+Fortunately, there's an easy fix that can be applied today. Use `safe-buffer` in place of
+`buffer`.
+
+```js
+var Buffer = require('safe-buffer').Buffer
+```
+
+Eventually, we hope that node.js core can switch to this new, safer behavior. We believe
+the impact on the ecosystem would be minimal since it's not a breaking change.
+Well-maintained, popular packages would be updated to use `Buffer.alloc` quickly, while
+older, insecure packages would magically become safe from this attack vector.

+# node-XMLHttpRequest #
+
+Fork of [node-XMLHttpRequest](https://github.com/driverdan/node-XMLHttpRequest) by [driverdan](http://driverdan.com). Forked and published to npm because a [pull request](https://github.com/rase-/node-XMLHttpRequest/commit/a6b6f296e0a8278165c2d0270d9840b54d5eeadd) is not being created and merged. Changes made by [rase-](https://github.com/rase-/node-XMLHttpRequest/tree/add/ssl-support) are needed for [engine.io-client](https://github.com/Automattic/engine.io-client).
+
+## Usage ## 
+
+Here's how to include the module in your project and use as the browser-based
+XHR object.
+
+	var XMLHttpRequest = require("xmlhttprequest-ssl").XMLHttpRequest;
+	var xhr = new XMLHttpRequest();
+
+Note: use the lowercase string "xmlhttprequest-ssl" in your require(). On
+case-sensitive systems (eg Linux) using uppercase letters won't work.

+## Usage ##

+
+	var XMLHttpRequest = require("xmlhttprequest").XMLHttpRequest;
+	var xhr = new XMLHttpRequest();
+
+Note: use the lowercase string "xmlhttprequest" in your require(). On
+case-sensitive systems (eg Linux) using uppercase letters won't work.
+
+## Versions ##
+
+Prior to 1.4.0 version numbers were arbitrary. From 1.4.0 on they conform to
+the standard major.minor.bugfix. 1.x shouldn't necessarily be considered
+stable just because it's above 0.x.
+
+Since the XMLHttpRequest API is stable this library's API is stable as
+well. Major version numbers indicate significant core code changes.
+Minor versions indicate minor core code changes or better conformity to
+the W3C spec.
+
+## License ##
+
+MIT license. See LICENSE for full details.
+
+## Supports ##
+
+* Async and synchronous requests
+* GET, POST, PUT, and DELETE requests
+* All spec methods (open, send, abort, getRequestHeader,
+  getAllRequestHeaders, event methods)
+* Requests to all domains
+
+## Known Issues / Missing Features ##
+
+For a list of open issues or to report your own visit the [github issues
+page](https://github.com/driverdan/node-XMLHttpRequest/issues).
+
+* Local file access may have unexpected results for non-UTF8 files
+* Synchronous requests don't set headers properly
+* Synchronous requests freeze node while waiting for response (But that's what you want, right? Stick with async!).
+* Some events are missing, such as abort
+* getRequestHeader is case-sensitive
+* Cookies aren't persisted between requests
+* Missing XML support
+* Missing basic auth

+
+Yeast is a unique id generator. It has been primarily designed to generate a
+unique id which can be used for cache busting. A common practice for this is
+to use a timestamp, but there are couple of downsides when using timestamps.
+
+1. The timestamp is already 13 chars long. This might not matter for 1 request
+   but if you make hundreds of them this quickly adds up in bandwidth and
+   processing time.
+2. It's not unique enough. If you generate two stamps right after each other,
+   they would be identical because the timing accuracy is limited to
+   milliseconds.
+
+Yeast solves both of these issues by:
+
+1. Compressing the generated timestamp using a custom `encode()` function that
+   returns a string representation of the number.
+2. Seeding the id in case of collision (when the id is identical to the previous
+   one).
+
+To keep the strings unique it will use the `.` char to separate the generated
+stamp from the seed.
+
+## Installation
+
+The module is intended to be used in browsers as well as in Node.js and is
+therefore released in the npm registry and can be installed using:
+
+```
+npm install --save yeast
+```
+
+## Usage
+
+All the examples assume that this library is initialized as follow:
+
+```js
+'use strict';
+
+var yeast = require('yeast');
+```
+
+To generate an id just call the `yeast` function.
+
+```js
+console.log(yeast(), yeast(), yeast()); // outputs: KyxidwN KyxidwN.0 KyxidwN.1
+
+setTimeout(function () {
+  console.log(yeast()); // outputs: KyxidwO
+});
+```
+
+### yeast.encode(num)
+
+An helper function that returns a string representing the specified number. The
+returned string contains only URL safe characters.
+
+```js
+yeast.encode(+new Date()); // outputs: Kyxjuo1
+```
+
+### yeast.decode(str)
+
+An helper function that returns the integer value specified by the given string.
+This function can be used to retrieve the timestamp from a `yeast` id.
+
+```js
+var id = yeast(); // holds the value: Kyxl1OU
+
+yeast.decode(id); // outputs: 1439816226334
+```
+
+That's all folks. If you have ideas on how we can further compress the ids
+please open an issue!
