Sending special session messages using socket.io and sails.js

Question

I am trying to implement private chat functions using the sails.js framework and I am having problems trying to send a message to a specific user.

Currently, I have achieved private communication by sending messages to a specific socket.id using socket.io .socket(socket.id).emit(event,message) , but the problem with this approach is that every time the user opens a new tab, new socket.id, for this new connection.

And my question is: does sails.js do a way to emit events (using socket.io) for a specific user session instead of a bunch of socket identifiers? is this possible with these technologies?

Therefore, I can send an event only once and make sure that it is received on all the tabs in which the chat application is now open.

Thanks in advance.

Sails complement all their models with some useful pubsub methods. Whenever you find a model through a socket request (for example, socket.get('/user/123') ), the requesting socket automatically subscribes to all messages about this model. Then you can call User.message(123, data) to send a message to all connected sockets for this user.
