easy-websocket

easy-websocket aims to be an easy to use websocket client for node.js, up-to-date against current HyBi protocol versions.

Passes the quite extensible Autobahn test suite. See http://einaros.github.com/easy-websocket for the full report.

Usage

Installing

npm install easy-websocket

Sending and receiving text data

var WebSocket = require('easy-websocket');
var ws = new WebSocket('ws://www.host.com/path');
ws.on('open', function() {
    ws.send('something');
});
ws.on('message', function(data, flags) {
    // flags.binary will be set if a binary data is received
    // flags.masked will be set if the data was masked
});

Sending binary data

var WebSocket = require('easy-websocket');
var ws = new WebSocket('ws://www.host.com/path');
ws.on('open', function() {
    var array = new Float32Array(5);
    for (var i = 0; i < array.length; ++i) array[i] = i / 2;
    ws.send(array, {binary: true, mask: true});
});

Setting mask, as done for the send options above, will cause the data to be masked according to the websocket protocol. The same option applies for text data.

echo.websocket.org demo

var WebSocket = require('easy-websocket');
var ws = new WebSocket('ws://echo.websocket.org/', {protocolVersion: 8, origin: 'http://websocket.org'});
ws.on('open', function() {
    console.log('connected');
    ws.send(Date.now().toString(), {mask: true});
});
ws.on('close', function() {
    console.log('disconnected');
});
ws.on('message', function(data, flags) {
    console.log('Roundtrip time: ' + (Date.now() - parseInt(data)) + 'ms', flags);
    setTimeout(function() {
        ws.send(Date.now().toString(), {mask: true});
    }, 500);
});

Other examples

See the test cases.
