Joining socket io room on connect

Question

I am trying to make a logged in user to join a certain socket.io room on connect. According to any examples I found on the net I seem to have emit some action from client to be able to join some room. Something like:

socket.on('connect', function() {    socket.emit('join', 'room1'); }); 

Server.js:

io.sockets.on('connection', function(socket) {     socket.on('join', function(room) {         socket.join(room);     }); }); 

And according to most tutorials it should work.

What I am thinkin to do is to:

socket.on('connect', function() {    socket.join('room1'); }); 

But It does not seem to work as whatever msg I emit from server are not caught on client. Any idea, what am I doing wrong? Is it possible in general?

This should be what you need. Feel free to pass in whatever room name you want through the client. Only the server can handle assigning a socket to a room.

Server:

io.sockets.on('connection', function(socket) {         socket.on('join', function(room) {         socket.join(room);     }); }); 

Client:

socket.emit('join', roomNum);
