Emit to Socket IO socket.id

Question

I am trying to emit to a particular socket ID:

socket(user[playID]).emit('correct', data);

But I'm getting:

TypeError: object is not a function

if I log out user[playID] I do get a valid socket ID.

Appreciated!

Here is my setup in case I'm missing something:.

// Tell Socket.io to pay attention
servio  = io.listen(server);

// Tell HTTP Server to begin listening for connections on port 3250
sock    = server.listen(3250);

Answer 1

This should do it

servio.sockets.socket(id).emit('hello');

This answer covers the same/similar topic. In short, consider keeping a reference to the connected clients yourself and emit to them as desired, rather than relying on socket.io's internals, which could change.
