the biggest problem in angular is that it is so hard to use a custom toolchain, i.e. not their angular/cli product instead mix it with other stuff in lets say vite

What kinds of features or workflows are you missing that Angular's CLI doesn't cover? Or is it just that you're used to Vite (or something else) and wish you could use that instead of Angular's own tooling?

I'm not on the Angular development team or anything, though I do use Angular at $DAY_JOB and I'm overall perfectly fine with the framework and its tooling. However, the grass might be greener elsewhere; I'm just not familiar with it!

explain your use case, I always wonder what kind of scenarios people do have, it is something easily solved? it is complicated? what is stopping you?

for many people this is the biggest bonus
