How to connect backend (node.js) with frontend (html5)? TCP sockets?

Question

Backend

It is planned to write simple games like chess. Client-server architecture. We plan to move the logic of the robot-opponent to the server with a back-end, Node.js, or Go. The frontend will be on HTML5 + PIXI.js, loaded like a regular site.
How do we connect the frontend to the backend for next moves and game tracking? TCP sockets with direct connection from JS (html5)? Or such connections are forbidden by modern browsers and we will get into trouble? :) Are there any methods of such communication between the server and the client that are better than this?

Answer 1

WebSocket is the best option.
