SYNC missed versions from official npm registry.


Forker notes

I(jacobbubu) made this fork beacuse WebSocket polyfill in react native does not implement EventTarget interface(https://github.com/facebook/react-native/issues/2583).

I've just changed 4 lines in stream.js to

  if (socket.readyState === 1) {
    stream = proxy
  } else {
    stream = duplexify.obj()
    // 1 changed here
    socket.onopen = onready

  // changed 3 lines
  socket.onclose = onclose
  socket.onerror = onerror
  socket.onmessage = onmessage


Use HTML5 websockets using the Node Streams API.


This module works in Node or in Browsers that support WebSockets. You can use browserify to package this module for browser use.

var websocket = require('websocket-stream')
var ws = websocket('ws://realtimecats.com')

In the example above ws is a duplex stream. That means you can pipe output to anything that accepts streams. You can also pipe data into streams (such as a webcam feed or audio data).

The underlying WebSocket instance is available as ws.socket.

On the server

Using the ws module you can make a websocket server and use this module to get websocket streams on the server:

var websocket = require('websocket-stream')
var wss = websocket.createServer({server: someHTTPServer}, handle)

function handle(stream) {

Run the tests

Server-side tests

npm test

Client-side tests

First start the echo server by running node test-server.js

Then run npm start and open localhost:9966 in your browser and open the Dev Tools console to see test output.
