+
+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')
