Socket.io Rooms

'use strict';

// I'd strongly recommend not using Socket.io rooms
// This will make it more difficult to switch to another
// WebSocket library that may not support rooms (SockJS?)
// You can use Redis or another data store to create rooms and add/remove users
// But, here it is for historical and educational purposes

// Socket.IO v0.7 now gives you one Socket per namespace you define:

var room1 = io.connect('/room1');
room1.on('message', function () {
    // chat socket messages
});
room1.on('disconnect', function () {
    // chat disconnect event
});

var room2 = io.connect('/room2');
room2.on('message', function () {
    // chat socket messages
});
room2.on('disconnect', function () {
    // chat disconnect event
});

// With different sockets, you can selectively send to the specific namespace you would like.
// Socket.IO v0.7 also has concept of "room"

io.sockets.on('connection', function (socket) {
    socket.join('room x');
    socket.broadcast.to('room x').send('hello');
    io.sockets.in('room y').emit('ohai');
});
