This is the appeal of Phoenix LiveView for me. Server rendering was already incredibly fast with Phoenix, but the ability to forgo the majority of JS with LiveView bypasses all of these framework complications.

Yes, LiveView is very exciting, although I haven't used it.

For those interested in LiveView-esque functionality in other frameworks , there are some similar projects cropping up:

- Django Reactor https://github.com/edelvalle/reactor

- Laravel Livewire: https://laravel-livewire.com/

- Rails Stimulus Reflex: https://docs.stimulusreflex.com/

- Intercooler.js: https://intercoolerjs.org/

I’d be very curious if those can be implemented in a performant way.

There’s a combination of low level features that combine to make LiveView work effectively.

Woah I had no idea that existed.

Here's a great introduction to LiveView:

This one's also pretty good: https://www.youtube.com/watch?v=MZvmYaFkNJI&t=1s (Build a real-time Twitter clone in 15 minutes with LiveView and Phoenix 1.5)
