I’ve also transitioned from PHP/Laravel and seeing this LiveView attempt in PHP is very interesting, even more so that it’s definitely not as easy and reliable to accomplish it as it is in the BEAM which feels like a natural habitat for this kind of stuff.
I expect this concept to pop out in every other framework out there in one way or another. But when you don’t have the BEAM ecosystem on your side for free you’ll have extra problems to overcome to achieve similar results.
Phoenix LiveView will bring tons of eyes on Elixir/Phoenix. It already does and it hasn’t even been released yet.
