Nodejs/express + ES6 recommendations?

Question

JavaScript

Good afternoon! I'm starting to learn nodejs / express, I started watching lessons from the loftblog, while everything is clear.
A couple of questions arise:
1. How can I use ES6 in such an assembly, also overtake the server.js file through babel or how?
2. How nodejs/express can be used in conjunction with React/redux, what project structure should be in such a project (1 or 2 packege.json should be, etc.)?
I would be grateful for any recommendations for studying)
