I think Phoenix LiveView (posted recently on HN: https://fly.io/blog/how-we-got-to-liveview/) and Rails Hotwire (https://hotwired.dev/) are the main alternatives that have momentum right now.

The general idea being to abstract away the difference between client and server code, so that you can write code that handles both, in a single file.
