A simple example of setting-up dynamic "rooms" for socket.io clients to join
View client.js
// set-up a connection between the client and the server
var socket = io.connect();
// let's assume that the client page, once rendered, knows what room it wants to join
var room = "abc123";
socket.on('connect', function() {
// Connected, let's sign-up for to receive messages for this room
socket.emit('room', room);
});
