Run SocketStream on Heroku

It's possible to run SocketStream applications on Heroku, even though Heroku does not support Websockets. Here's how.

1 - In your application's package.json file, add the ss-engine.io npm as a dependency:

"dependencies": {
  "ss-engine.io":"0.1.0"
}

2 - In your application's app.js file, add the following code:

ss.ws.transport.use(require('ss-engine.io'), {
  client: {
    transports: ["polling"],
    upgrade: false
  },
  server: {
    transports: ["polling"],
    allowUpgrades: false,
    pingInterval: 10000
  }
});

3 - In order to make SocketStream install on Heroku without problems, change the npm dependency version for SocketStream to this:

"socketstream":"git://github.com/socketstream/socketstream.git"

SocketStream has replaced Socket.io with Engine.io. This is currently in the master branch of SocketStream's codebase, and is likely to feature in the coming 0.3.3 release.
