A simple example of setting-up dynamic "rooms" for clients to join
// 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);
socket.on('message', function(data) {
console.log('Incoming message:', data);
// attach to our HTTP server
io = socketio.listen(server);
// handle incoming connections from clients
io.sockets.on('connection', function(socket) {
// once a client has connected, we expect to get a ping from them saying what room they want to join
socket.on('room', function(room) {
// now, it's easy to send a message to just the clients in a given room
room = "abc123";'message', 'what is going on, party people?');
// this message will NOT go to the client defined above'foobar').emit('message', 'anyone in this room yet?');
