Angular + Wordpress (like backend), where to dig?

Question

Angular

Good evening.
There was a need to make a project in conjunction with Angular + Wordpress, and immediately a few questions arose:
1) How to organize the connection between these two components?
- At the moment, I found only this , but there may be more resources that I do not know about.
2) How will the project work in a production environment?
Will the resulting html file (the same one that angular-cli spits out when ng build command) be renamed to .php and then uploaded to wordpress as a theme, or maybe there are other options?

Answer 1

1) You separate your application into API and client - communicate using JSON, everything is very simple
2) No, of course it will be index.html, the usual single-page-app.
If you want to embed Angular in WordPress, then it is better to use version 1 for this.

Answer 2

It doesn't really matter if you use version 1 or 2, but for reasons of novelty and performance, version 2 is preferable.
Angular takes data from any REST server, that is, you need to dig in the direction of
https://developer.wordpress.org/rest-api/
v2.wp-api.org

The WordPress REST API makes it easier than ever to use WordPress in new and exciting ways, such as creating Single Page Applications on top of WordPress.
