Set variable on socket connection

[ughstudios]

Is it possible to set a variable on a socket connection to be permanently there?

For example:
io.on('connection', client => { client.lobby_id = "sadjasdhjkas"; });

I want client.id to be there until it disconnects obviously. Would this mean that the variable lobby_id will always be there for that client socket connection, and could i access it in any events?

Yes indeed. As long as you don't overwrite a property of the socket object (ref here), it should work.
