How to get started with NodeJS?

Question

JavaScript

Hello, there is a project, now it works entirely on the client side.
In the project, if it is important, a webgl framework is used, which uses RequireJS if it is important.
The task is to translate the application to ES6, implement the ability to upload json and bin files to the server and make this file available from the application (the application's work is based on parsing this file and then working with it).
Computer running Linux, nodejs and npm already installed.

Answer 1

judging by the keywords (webgl, requirejs) as well as es6, I have only one question - what does node.js have to do with it?
And so you take it and start.
