Using Primus instead of socket-io with simplewebrtc

Question

I want to use Primus instead of socket-io with simplewebrtc. Can any one help me to convert the below code to use Primus? https://github.com/andyet/SimpleWebRTC/blob/master/socketioconnection.js

How this works is that you can pass any constructor as the connection property to the config, and any additional options you need. Then, all your constructor needs to do is export an object with the four methods: on, emit, getSessionId, and disconnect. For Primus, you could have something like this (I've never used Primus before, just looking at docs) -

var Primus = window.Primus; // get primus from wherever you want

function PrimusConnection(config) {
    var self = this;
    var primus = new Primus(config.url, config.primus);
    primus.on('connection', function (spark) {
      // spark is the new connection.
      self.connection = spark;
    });
}

PrimusConnection.prototype.on = function (eventName, function) {
    this.connection.on(eventName, function);
};

PrimusConnection.prototype.emit = function () {
    this.connection.write.apply(this.connection, arguments);
};

PrimusConnection.prototype.getSessionid = function () {
    return this.connection.id;
};

PrimusConnection.prototype.disconnect = function () {
    return this.connection.end.apply(this.connection, arguments);
};

module.exports = PrimusConnection;
