I'm more interested in the concept of ViewComponents than just the current library. It's really just starting with Rails adopting ActionCable and Phoenix using LiveView (which I see as both immature proto-concepts of the future of JS frontends).

This blog post (and my linked talk above) opened my eyes on the subject: https://evilmartians.com/chronicles/anycable-actioncable-on-...

Right now the complexity is a bit high on this approach^ and I personally just use a mix of Vue + Turbolinks/Rails at work for legacy/simplicity reasons. But I'm watching the space.
