Socket.io's readme contains the following example:
var io = require('socket.io').listen(80);
io.sockets.on('connection', function (socket) {
socket.join('justin bieber fans');
socket.broadcast.to('justin bieber fans').emit('new fan');
io.sockets.in('rammstein fans').emit('new non-fan');
});
What's the difference between socket.broadcast.to()
and io.sockets.in()
?
