# ws: a Node.js WebSocket library
|

|
||||||
|
[](https://www.npmjs.com/package/ws)
|
||||||
|
[](https://github.com/websockets/ws/actions?query=workflow%3ACI+branch%3Amaster)
|
||||||
|
[](https://coveralls.io/github/websockets/ws)
|
||||||
|
|
||||||
|
ws is a simple to use, blazing fast, and thoroughly tested WebSocket client and
|
||||||
|
server implementation.
|
||||||
|
|
||||||
|
Passes the quite extensive Autobahn test suite: [server][server-report],
|
||||||
|
[client][client-report].
|
||||||
|
|
||||||
|
**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. To make the same code work seamlessly on Node.js and the browser, you
|
||||||
|
can use one of the many wrappers available on npm, like
|
||||||
|
[isomorphic-ws](https://github.com/heineiuo/isomorphic-ws).

## Protocol support
|
||||||
|
|
||||||
|
- **HyBi drafts 07-12** (Use the option `protocolVersion: 8`)
|
||||||
|
- **HyBi drafts 13-17** (Current default, alternatively option
|
||||||
|
`protocolVersion: 13`)
|
||||||
|
|
||||||
|
## Installing
|
||||||
|
|
||||||
|
```
|
||||||
|
npm install ws
|
||||||
|
```
|
||||||
|
|
||||||
|
### Opt-in for performance
|
||||||
|
|
||||||
|
[bufferutil][] is an optional module that can be installed alongside the ws
|
||||||
|
module:
|
||||||
|
|
||||||
|
```
|
||||||
|
npm install --save-optional bufferutil
|
||||||
|
```
|
||||||
|
|
||||||
|
This is a binary addon that improves the performance of certain operations such
|
||||||
|
as masking and unmasking the data payload of the WebSocket frames. Prebuilt
|
||||||
|
binaries are available for the most popular platforms, so you don't necessarily
|
||||||
|
need to have a C++ compiler installed on your machine.
|
||||||
|
|
||||||
|
To force ws to not use bufferutil, use the
|
||||||
|
[`WS_NO_BUFFER_UTIL`](./doc/ws.md#ws_no_buffer_util) environment variable. This
|
||||||
|
can 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.
|
||||||
|
|
||||||
|
#### Legacy opt-in for performance
|
||||||
|
|
||||||
|
If you are running on an old version of Node.js (prior to v18.14.0), ws also
|
||||||
|
supports the [utf-8-validate][] module:
|
||||||
|
|
||||||
|
```
|
||||||
|
npm install --save-optional utf-8-validate
|
||||||
|
```
|
||||||
|
|
||||||
|
This contains a binary polyfill for [`buffer.isUtf8()`][].
|
||||||
|
|
||||||
|
To force ws to not use utf-8-validate, use the
|
||||||
|
[`WS_NO_UTF_8_VALIDATE`](./doc/ws.md#ws_no_utf_8_validate) environment variable.
|
||||||
|
|
||||||
|
## 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
|

### Server broadcast
|
||||||
|
|
||||||
|
A client WebSocket broadcasting to all connected WebSocket clients, including
|
||||||
|
itself.
|
||||||
|
|
||||||
|
```js
|
||||||
|
import WebSocket, { 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, isBinary) {
|
||||||
|
wss.clients.forEach(function each(client) {
|
||||||
|
if (client.readyState === WebSocket.OPEN) {
|
||||||
|
client.send(data, { binary: isBinary });
|
||||||
|
}
|
||||||
|
});
|
||||||
|
});
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
A client WebSocket broadcasting to every other connected WebSocket clients,
|
||||||
|
excluding itself.
|
||||||
|
|
||||||
|
```js
|
||||||
|
import WebSocket, { 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, isBinary) {
|
||||||
|
wss.clients.forEach(function each(client) {
|
||||||
|
if (client !== ws && client.readyState === WebSocket.OPEN) {
|
||||||
|
client.send(data, { binary: isBinary });
|
||||||
|
}
|
||||||
|
});
|
||||||
|
});
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Round-trip time
|
||||||
|
|
||||||
|
```js
|
||||||
|
import WebSocket from 'ws';
|
||||||
|
|
||||||
|
const ws = new WebSocket('wss://websocket-echo.com/');
|
||||||
|
|
||||||
|
ws.on('error', console.error);
|
||||||
|
|
||||||
|
ws.on('open', function open() {
|
||||||
|
console.log('connected');
|
||||||
|
ws.send(Date.now());
|
||||||
|
});
|
||||||
|
|
||||||
|
ws.on('close', function close() {
|
||||||
|
console.log('disconnected');
|
||||||
|
});
|
||||||
|
|
||||||
|
ws.on('message', function message(data) {
|
||||||
|
console.log(`Round-trip time: ${Date.now() - data} ms`);
|
||||||
|
|
||||||
|
setTimeout(function timeout() {
|
||||||
|
ws.send(Date.now());
|
||||||
|
}, 500);
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### Use the Node.js streams API
|
||||||
|
|
||||||
|
```js
|
||||||
|
import WebSocket, { createWebSocketStream } from 'ws';
|
||||||
|
|
||||||
|
const ws = new WebSocket('wss://websocket-echo.com/');
|
||||||
|
|
||||||
|
const duplex = createWebSocketStream(ws, { encoding: 'utf8' });
|
||||||
|
|
||||||
|
duplex.on('error', console.error);
|
||||||
|
|
||||||
|
duplex.pipe(process.stdout);
|
||||||
|
process.stdin.pipe(duplex);
|
||||||
|
```
|
||||||
|
|
||||||
|
### Other examples
|
||||||
|
|
||||||
|
For a full example with a browser client communicating with a ws server, see the
|
||||||
|
examples folder.
|
||||||
|
|
||||||

## FAQ
|
||||||
|
|
||||||
|
### How to get the IP address of the client?
|
||||||
|
|
||||||
|
The remote IP address can be obtained from the raw socket.
|
||||||
|
|
||||||
|
```js
|
||||||
|
import { WebSocketServer } from 'ws';
|
||||||
|
|
||||||
|
const wss = new WebSocketServer({ port: 8080 });
|
||||||
|
|
||||||
|
wss.on('connection', function connection(ws, req) {
|
||||||
|
const ip = req.socket.remoteAddress;
|
||||||
|
|
||||||
|
ws.on('error', console.error);
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
When the server runs behind a proxy like NGINX, the de-facto standard is to use
|
||||||
|
the `X-Forwarded-For` header.
|
||||||
|
|
||||||
|
```js
|
||||||
|
wss.on('connection', function connection(ws, req) {
|
||||||
|
const ip = req.headers['x-forwarded-for'].split(',')[0].trim();
|
||||||
|
|
||||||
|
ws.on('error', console.error);
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### How to detect and close broken connections?
|
||||||
|
|
||||||
|
Sometimes the link between the server and the client can be interrupted in a way
|
||||||
|
that keeps both the server and the client unaware of the broken state of the
|
||||||
|
connection (e.g. when pulling the cord).
|
||||||
|
|
||||||
|
In these cases ping messages can be used as a means to verify that the remote
|
||||||
|
endpoint is still responsive.
|
||||||
|
|
||||||
|
```js
|
||||||
|
import { WebSocketServer } from 'ws';
|
||||||
|
|
||||||
|
function heartbeat() {
|
||||||
|
this.isAlive = true;
|
||||||
|
}
|
||||||
|
|
||||||
|
const wss = new WebSocketServer({ port: 8080 });
|
||||||
|
|
||||||
|
wss.on('connection', function connection(ws) {
|
||||||
|
ws.isAlive = true;
|
||||||
|
ws.on('error', console.error);
|
||||||
|
ws.on('pong', heartbeat);
|
||||||
|
});
|
||||||
|
|
||||||
|
const interval = setInterval(function ping() {
|
||||||
|
wss.clients.forEach(function each(ws) {
|
||||||
|
if (ws.isAlive === false) return ws.terminate();
|
||||||
|
|
||||||
|
ws.isAlive = false;
|
||||||
|
ws.ping();
|
||||||
|
});
|
||||||
|
}, 30000);
|
||||||
|
|
||||||
|
wss.on('close', function close() {
|
||||||
|
clearInterval(interval);
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
Pong messages are automatically sent in response to ping messages as required by
|
||||||
|
the spec.
|
||||||
|
|
||||||
|
Just like the server example above your clients might as well lose connection
|
||||||
|
without knowing it. You might want to add a ping listener on your clients to
|
||||||
|
prevent that. A simple implementation would be:
|
||||||
|
|
||||||
|
```js
|
||||||
|
import WebSocket from 'ws';
|
||||||
|
|
||||||
|
function heartbeat() {
|
||||||
|
clearTimeout(this.pingTimeout);
|
||||||
|
|
||||||
|
// Use `WebSocket#terminate()`, which immediately destroys the connection,
|
||||||
|
// instead of `WebSocket#close()`, which waits for the close timer.
|
||||||
|
// Delay should be equal to the interval at which your server
|
||||||
|
// sends out pings plus a conservative assumption of the latency.
|
||||||
|
this.pingTimeout = setTimeout(() => {
|
||||||
|
this.terminate();
|
||||||
|
}, 30000 + 1000);
|
||||||
|
}
|
||||||
|
|
||||||
|
const client = new WebSocket('wss://websocket-echo.com/');
|
||||||
|
|
||||||
|
client.on('error', console.error);
|
||||||
|
client.on('open', heartbeat);
|
||||||
|
client.on('ping', heartbeat);
|
||||||
|
client.on('close', function clear() {
|
||||||
|
clearTimeout(this.pingTimeout);
|
||||||
|
});
|
||||||
|
```
|
||||||
|
|
||||||
|
### How to connect via a proxy?
|
||||||
|
|
||||||
|
Use a custom `http.Agent` implementation like [https-proxy-agent][] or
|
||||||
|
[socks-proxy-agent][].
