Socket chat on go?

Question

go

Good afternoon, I'm trying to deal with sockets on go.
How to identify a specific connection.
For example, one user gives the server such a request {action:message,from_id:111,to_id:222,message:'Hi. How are you?'}

The server should answer {status:true} and go through all connected users, find user id 222 there and send this message specifically to him.

Using the example from here https://www.youtube.com/watch?v=ysAZ_oqPOo0
with packages from here github.com/gorilla/websocket .

But here is a general chat. It is necessary to somehow filter from whom and to whom to send data.
How to do it?
Thanks

The pub-sub pattern is used. You can see the working prototype at https://github.com/uvelichitel/nezabu/ (Sorry for the light self-promotion, you can use the code at your discretion.)

google for "pub sub"
