How to properly build node js applications (sites)?

Question

JavaScript

There is a site (web application), which consists of index.html, a couple of styles and several node modules that are connected via index.js.
1. How to build a website correctly? (for subsequent submission to github, so that a person can copy the repository and download the dependencies himself)
2. Who can advise a good guide (not necessarily in Russian)
3. How to build applications if node modules are used, but there is also a php part of the project?
Thanks in advance for the detailed answer!
