chassis.io v0.1.0

Chassis.IO

A lightweight wrapper around engine.io to let you add real-time features to your Express.js application.

Installation

npm install chassis.io

Setting up Chassis.io in your app

    var chassis = require('chassis.io'),
        server  = express.createServer();

    // Use the same interface that you would with
    // attaching engine.io to your Express server.
    var app = chassis.attach(server, options);
    app.listen(3000);

You'll also need to add the following client-side JS libraries to your web application:

• Engine.io-client
• Chassis.io-client

TODO - put links to there libraries above

In this order:

    
    <script src="/js/engine.io.js"></script>
    <script src="/js/chassis.io.js"></script>

Background

Chassis.io was built as a replacement of the NowJS library in one of our applications. It's designed to mimic some of NowJS' functionality, but to also solve some of the challenges of running a websocket-based application across multiple Node.js processes.
