Send response to all clients except sender

Question

To send something to all clients, you use:

io.sockets.emit(\'response\', data);

To receive from clients, you use:

socket.on         


        

Answer 1

For namespaces within rooms looping the list of clients in a room (similar to Nav's answer) is one of only two approaches I've found that will work. The other is to use exclude. E.G.

socket.on('message',function(data) {
    io.of( 'namespace' ).in( data.roomID ).except( socket.id ).emit('message',data);
}
