Answer 1

🇵🇱Amadeus if you intend to use node.js as the backend then of course
there are plenty of tutorials available so my suggestion is find a nice tutorial for socket.io + node.js and try to understand the inner working of it
explore any line of code you don't understand in the tutorial.
eventually it will become clear

Answer 2

you should use web sockets (if you aren't)
https://socket.io

@Burey Should I learn Node.js before using Socket.io?
