Peer Dependencies

isomorphic-ws

Isomorphic implementation of WebSocket.

It uses:

ws on Node
global.WebSocket in browsers

Limitations

Before using this module you should know that ws is not perfectly API compatible with WebSocket, you should always test your code against both Node and browsers.

Some major differences:

no Server implementation in browsers
no support for the constructor options argument in browsers

Usage

You need to install both this package and ws:

> npm i isomorphic-ws ws

Then just require this package:

1const WebSocket = require('isomorphic-ws');
2
3const ws = new WebSocket('wss://echo.websocket.org/');
4
5ws.onopen = function open() {
6  console.log('connected');
7  ws.send(Date.now());
8};
9
10ws.onclose = function close() {
11  console.log('disconnected');
12};
13
14ws.onmessage = function incoming(data) {
15  console.log(`Roundtrip time: ${Date.now() - data.data} ms`);
16
17  setTimeout(function timeout() {
18    ws.send(Date.now());
19  }, 500);
20};
