I'm mostly an Elixir dev and use LiveView ( the tech that inspired Live wire) it would be so nice to have these kinds of component framework in the elixir ecosystem on top of Phoenix.
I love the component based system and use it extensively (via surface-ui in fact as I started using it 2 years ago). It's more about having a strong component library.
There is Petal[1] that looks like the most advanced one right now, but not yet as complete.
