How to respond to users on a page with a specific URL in socket.io?

Question

Node.js

Hello! Using laravel + socket.io + redis, I am learning how to work with real-time technologies. The question arose, how best to return a response to a page with a specific id (by type - sample.com/id/2, sample.com/id/3, sample.com/id/{id}) from the nodejs server?
How to do it correctly? Thank you.
