Backend Setup

Parts 1-2

  1. How to set up a modern Javascript project (rwieruch 2019 Jun)
  2. The minimal Node.js with Babel Setup (rwieruch 2019 Jun)

Note comment: https://www.robinwieruch.de/minimal-node-js-babel-setup/#comment-4056355053

You can already use many ES6 features natively as of Node 7. Babel is only useful for ESM, or perhaps React server-rendered apps as well. Also, without any configuration, babel-preset-env will transpile language constructs like async/await into their ES5 implementations, even though the original code can still run on Node.

But ES6 import and export cannot be used without an experimental Node flag. Node does not yet support all the ES6 natively, unfortunately.
