That depends very much on what type of product you're building. I work on two "serious" enterprise products using Angular, and for one of them the "core technology" is evenly split between the Java backend and the Angular application, while for the other the Angular application is clearly the "core technology."

Indeed. I work in a similar kind of product. I was talking about the majority of cases though. There are even cases where the mobile app is the core and only technology.

Now what would be interesting questions though are: 1) How many people work in the backend and how many work in each of the respective front-ends.

2) Suppose that you had 2 front-end interfaces, angular(for the web) and an android app(it could be an iPhone app, it doesn't matter). How many backend devs would need to know or actively interact with the angular front-end and how many would need to interact with the android app.

In my case, none of the backend people(a lot) need to interact with the mobile codebase(2-people team for every mobile type), while all of us need to help or interact with the web front-end.

I see similar scenarios with most of the companies I interact or know about. The mobile team is almost always autonomous and can accomplish a lot with just a few people. While hords of people are thrown into the web frontend, even if it's not their primary specialty. Hence the need for fullstack developers. Why? Because the JS ecosystem sucks and we still don't have a real integrated solution. I hope that this will change, preferably before I retire.

Stop trying to shoehorn your backend into your web frontend, and treat the web frontend like the mobile one. That means, one single HTTP API to access the backend for both. I bet you already have this for your mobile app.

More often than not, the web frontend ends up being client side HTML/JS and some sort of intermediate middle-end server that hosts that HTML/JS. That way it turns into a fullstack app that does some processing on the middle-end to pass it on to the front-end JS.

You can make the frontend 100% static HTML/JS (and serveable off any static file CDN), so all you have to worry about is the API between them.
