Ask HN: What are modern front ends for RxJS?

I'm catching up on React and seeing the changes that have happened recently which include hooks. Needless to say I'm not thrilled. When I was last heavy into frontend, I was excited by cljs atoms and top down virtual dom rendering. I had my front end and backend being rendered by the same codebase.

What I'd like to be able to do is render something using RxJS + Typescript. What gui libraries are best to use for that these days? Am I looking at only Bootstrap?
