What is the correct folder structure in an AngularJS application with a NodeJS backend?

Question

Angular

I'm going to make an Angular application from scratch. The backend will be on Node (express)
In all training materials, Angular is connected with a tag in html and the controllers.js file with controllers is also included.
But what if there are a lot of controllers and they are divided into several files? All in html to cut? I'm new to this, but I don't understand if this is a normal practice at all. Or maybe webpack is needed for such cases?
Also about the question itself in the title: I would like to know how a normal angular application of an experienced developer looks in general, which is no longer ashamed to show. If you know github repositories, please share links, or tutorials / videos, etc.
