问题
I've been following Firebase cloud functions for a while now. Recently I came across hosting Node.js apps on Firebase Hosting, but it was using just express.
Can we host socket.io apps on Firebase?

This is not possible with Firebase Hosting, even if it's hooked up to Cloud Functions to provide a backend.
If you want realtime socket communication between clients, consider using Realtime Database as a conduit between them. You'll get more done, write less code, and scale easier this way.
