Implement Rooms

[gil0mendes]

Within each namespace, you can also define arbitrary channels that sockets can join and leave.

Joining and leaving

You can call join to subscribe the socket to a given channel:

socket.on('connection', (socket) {
  socket.join('funny_room');
});

And then simply use to when emitting:

socket.to('funny_room').emit('some event');

To leave a channel you call leave in the same fashion as join.

Default room

Each Socket in Connexa is identified by a random, unguessable, unique identifier Socket#id. For your convenience, each socket automatically joins a room identified by this id.

This makes it easy to broadcast messages to other sockets:

server.on('connection', (socket) {
  socket.on('say to someone', (from, msg) {
    socket.to(from.id).emit('my message', msg);
  });
});

Disconnection

Upon disconnection, socket leave all the channels they were part of automatically, and so specially teardown is needed on your part.
