I don't use Elixir/Phoenix, but Phoenix's LiveViews brings all the butter to the monolith bread. State remains on the server, only visual state is sent over websockets, and the HTML is transformed with morphDOM.

I hope to see this idea brought to Rails, but the its websocket story doesn't seem there yet.

It's a combination of the websocket story and the server side HTML story that make this possible.

HTML rendering with Phoenix is lightning fast. https://www.bignerdranch.com/blog/elixir-and-io-lists-part-2...

I agree - it seems like a LiveView equivalent for Rails should be doable in principle. Check out these two projects, they're sorta heading in that direction: Fie: https://fie.eranpeer.co/ AnyCable: https://anycable.io/

If you watch Chris Mccord's videos (the creator of Phoenix and LiveView), it was an attempt to build a similar system for Rails that drove him to create Phoenix. The Ruby/Rails concurrency model mean that he was patching over so many cracks to try and get it to work, and it never quite did.
