What is the equivalent of "connect.id" in Node.js?

Question

JavaScript

I'm trying to implement "authorization using MySQL" on node.js
In a nutshell, I'll describe the key steps:
1) When the application starts, it connects to my WebSocketServer'y
2) When entering login / pass, the server checks if the pair is valid or not. If login & pas are correct, then in MySQL the `online` table is changed to 'yes' (for the corresponding login)
. And then the question arises. How to determine who exactly disconnected? Those. what is his login?
