These might be useful to enhance security in systems where a user can +put a package in the package search path of an application of another user, due +to how the Node.js resolver algorithm works. + +The `utf-8-validate` module is not needed and is not required, even if it is +already installed, regardless of the value of the `WS_NO_UTF_8_VALIDATE` +environment variable, if [`buffer.isUtf8()`][] is available. + +## API docs + +See [`/doc/ws.md`](./doc/ws.md) for Node.js-like documentation of ws classes and +utility functions. + +## 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 disabled by default on the server and enabled by default on the +client. It adds a significant overhead in terms of performance and memory +consumption so we suggest to enable it only if it is really needed. + +Note that Node.js has a variety of issues with high-performance compression, +where increased concurrency, especially on Linux, can lead to [catastrophic +memory fragmentation][node-zlib-bug] and slow performance. If you intend to use +permessage-deflate in production, it is worthwhile to set up a test +representative of your workload and ensure Node.js/zlib will handle it with +acceptable performance and memory usage. + +Tuning of permessage-deflate can be done via the options defined below. You can +also use `zlibDeflateOptions` and `zlibInflateOptions`, which is passed directly +into the creation of [raw deflate/inflate streams][node-zlib-deflaterawdocs]. + +See [the docs][ws-server-options] for more options. + +```js +import WebSocket, { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ + port: 8080, + perMessageDeflate: { + zlibDeflateOptions: { + // See zlib defaults. + chunkSize: 1024, + memLevel: 7, + level: 3 + }, + zlibInflateOptions: { + chunkSize: 10 * 1024 + }, + // Other options settable: + clientNoContextTakeover: true, // Defaults to negotiated value. + serverNoContextTakeover: true, // Defaults to negotiated value. + serverMaxWindowBits: 10, // Defaults to negotiated value. + // Below options specified as default values. + concurrencyLimit: 10, // Limits zlib concurrency for perf. + threshold: 1024 // Size (in bytes) below which messages + // should not be compressed if context takeover is disabled. + } +}); +``` + +The client will only use the extension if it is supported and enabled on the +server. To always disable the extension on the client set the +`perMessageDeflate` option to `false`. + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path', { + perMessageDeflate: false +}); +``` + +## Usage examples + +### Sending and receiving text data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('error', console.error); + +ws.on('open', function open() { + ws.send('something'); +}); + +ws.on('message', function message(data) { + console.log('received: %s', data); +}); +``` + +### Sending binary data + +```js +import WebSocket from 'ws'; + +const ws = new WebSocket('ws://www.host.com/path'); + +ws.on('error', console.error); + +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); +}); +``` + +### Simple server + +```js +import { WebSocketServer } from 'ws'; + +const wss = new WebSocketServer({ port: 8080 }); + +wss.on('connection', function connection(ws) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log('received: %s', data); + }); + + ws.send('something'); +}); +``` + +### External HTTP/S server + +```js +import { createServer } from 'https'; +import { readFileSync } from 'fs'; +import { WebSocketServer } from 'ws'; + +const server = createServer({ + cert: readFileSync('/path/to/cert.pem'), + key: readFileSync('/path/to/key.pem') +}); +const wss = new WebSocketServer({ server }); + +wss.on('connection', function connection(ws) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log('received: %s', data); + }); + + ws.send('something'); +}); + +server.listen(8080); +``` + +### Multiple servers sharing a single HTTP/S server + +```js +import { createServer } from 'http'; +import { parse } from 'url'; +import { WebSocketServer } from 'ws'; + +const server = createServer(); +const wss1 = new WebSocketServer({ noServer: true }); +const wss2 = new WebSocketServer({ noServer: true }); + +wss1.on('connection', function connection(ws) { + ws.on('error', console.error); + + // ... +}); + +wss2.on('connection', function connection(ws) { + ws.on('error', console.error); + + // ... +}); + +server.on('upgrade', function upgrade(request, socket, head) { + const { pathname } = parse(request.url); + + if (pathname === '/foo') { + wss1.handleUpgrade(request, socket, head, function done(ws) { + wss1.emit('connection', ws, request); + }); + } else if (pathname === '/bar') { + wss2.handleUpgrade(request, socket, head, function done(ws) { + wss2.emit('connection', ws, request); + }); + } else { + socket.destroy(); + } +}); + +server.listen(8080); +``` + +### Client authentication + +```js +import { createServer } from 'http'; +import { WebSocketServer } from 'ws'; + +function onSocketError(err) { + console.error(err); +} + +const server = createServer(); +const wss = new WebSocketServer({ noServer: true }); + +wss.on('connection', function connection(ws, request, client) { + ws.on('error', console.error); + + ws.on('message', function message(data) { + console.log(`Received message ${data} from user ${client}`); + }); +}); + +server.on('upgrade', function upgrade(request, socket, head) { + socket.on('error', onSocketError); + + // This function is not defined on purpose.
