socket.io join/leave

Question

I\'m on the socket.io wiki looking into using rooms but join and leave are not working, i\'m wondering if they may have changed up a few things but not had the chance to update

Answer 1

You're probably not declaring 'socket' correctly either that of you haven't installed Socket-io correctly. Try the following...

var io = require("socket.io");

var socket = io.listen(80);

socket.join('room');

socket.leave('room');

There's a useful executable example here.

Answer 2

It looks like you had the socket.join on the client side. Its a server side function.

Put this on the server:

io.sockets.on('connection', function (socket) {

    socket.on('subscribe', function(data) { socket.join(data.room); })

    socket.on('unsubscribe', function(data) { socket.leave(data.room); })

});

setInterval(function(){
    io.sockets.in('global').emit('roomChanged', { chicken: 'tasty' });
}, 1000);

And this on the client:

var socket = io.connect();

socket.emit("subscribe", { room: "global" });

socket.on("roomChanged", function(data) {
    console.log("roomChanged", data);
});
