This may help :

server.js (without the code regarding redis)

var usernames = {};

var rooms = ['Lobby'];

io.sockets.on('connection', function(socket) {
    socket.on('adduser', function(username) {
        socket.username = username;
        socket.room = 'Lobby';
        usernames[username] = username;
        socket.join('Lobby');
        socket.emit('updatechat', 'SERVER', 'you have connected to Lobby');
        socket.broadcast.to('Lobby').emit('updatechat', 'SERVER', username + ' has connected to this room');
        socket.emit('updaterooms', rooms, 'Lobby');
    });

    socket.on('create', function(room) {
        rooms.push(room);
        socket.emit('updaterooms', rooms, socket.room);
    });

    socket.on('sendchat', function(data) {
        io.sockets["in"](socket.room).emit('updatechat', socket.username, data);
    });

    socket.on('switchRoom', function(newroom) {
        var oldroom;
        oldroom = socket.room;
        socket.leave(socket.room);
        socket.join(newroom);
        socket.emit('updatechat', 'SERVER', 'you have connected to ' + newroom);
        socket.broadcast.to(oldroom).emit('updatechat', 'SERVER', socket.username + ' has left this room');
        socket.room = newroom;
        socket.broadcast.to(newroom).emit('updatechat', 'SERVER', socket.username + ' has joined this room');
        socket.emit('updaterooms', rooms, newroom);
    });

    socket.on('disconnect', function() {
        delete usernames[socket.username];
        io.sockets.emit('updateusers', usernames);
        socket.broadcast.emit('updatechat', 'SERVER', socket.username + ' has disconnected');
        socket.leave(socket.room);
    });
 });
