Installation is done using the +[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally): + +```sh +$ npm install proxy-addr +``` + +## API + + + +```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. + + + +```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. + + + +```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`). + + + +```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: + + + +```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`). + + + +```js +proxyaddr.all(req) +``` + +The optional `trust` argument takes the same arguments as `trust` +does in `proxyaddr(req, trust)`. + + + +```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)`. + + + +```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. + +## Testing + +```sh +$ npm test +``` + +## Benchmarks + +```sh +$ npm run-script bench +``` + +## License + +[MIT](LICENSE) + +[npm-image]: https://img.shields.io/npm/v/proxy-addr.svg +[npm-url]: https://npmjs.org/package/proxy-addr +[node-version-image]: https://img.shields.io/node/v/proxy-addr.svg +[node-version-url]: https://nodejs.org/en/download/ +[travis-image]: https://img.shields.io/travis/jshttp/proxy-addr/master.svg +[travis-url]: https://travis-ci.org/jshttp/proxy-addr +[coveralls-image]: https://img.shields.io/coveralls/jshttp/proxy-addr/master.svg +[coveralls-url]: https://coveralls.io/r/jshttp/proxy-addr?branch=master +[downloads-image]: https://img.shields.io/npm/dm/proxy-addr.svg +[downloads-url]: https://npmjs.org/package/proxy-addr -- cgit v1.2.3
