MaxtheCat,
I suggest you relax, enjoy a coffee, a beer, a glass of wine, or whatever you like and watch a few YT videos, for example:
The Net Ninja:
Node JS Tutorial for Beginners #1 - Introduction - YouTube
AngularJS Tutorial #1 - Introduction to AngularJS - YouTube
Traversy Media:
Angular Crash Course - 2019 - YouTube
Node.js Crash Course - YouTube
These tutorials will take you well on your way to understanding Angular and node.js. Thirty minutes of video tutorials will help you greatly (hours are even better) and are generally more useful, and often more entertaining, than watching a movie rerun on TV or a Netflix video.
You do not need to watch all of them or the entire series on one playlist if you do not want to learn Angular and Node, but you should at least learn the basics of what you are doing when you are installing an Angular application.
If you do not understand the basics, how can you build and deploy an Angular app?
From your posts, you seem be missing a basic understanding of what an Angular application is and how to build and deploy it. You are seemingly trying to deploy it without building it; and this is not now modern SPA applications are deployed. You must build the application using node.js, normally on your desktop, then deploy it to a web server (remotely).
Developers, like me, develop, build and deploy node.js apps like this continually, BTW. But we normally run node.js in dev mode before we build. All of that is described in the each of tutorials above. Just pick one and learn a bit about what you are trying to do.
I prefer Vue.js over Angular, but that's just my personal preference.
