socket.io client to client messaging

Question

I\'m having trouble getting basic client to client (or really client->server->client) working with socket.io. Heres the code I have right now:

io.sockets.on(         


        

Answer 1

Try

users.push(socket); // without .sessionId

for (var u in users)    {
   // users[u] is now the socket
   console.log(users[u].id);
   users[u].emit('message', { msg: 'New User Connected succesfully' });
}

Answer 2

You can now also use ...

io.to('room').emit('event_name', data);

as an alternative to io.sockets.in

Answer 3

Socket.io has the concept of rooms where, once a socket has joined a room, it will receive all message sent to a room, so you don't need to track who's in the room, deal with disconnections, etc...

On connection, you'd use:

socket.join('room')

And to send a message to everyone in that room:

io.sockets.in('room').emit('event_name', data)
