You can write full-blown SPAs in ClojureScript or Elm, or use the tools we're discussing here like LiveView.

I've had great success with an LV app with minimal JS. The rendering is all server-side in Elixir, plus a few lines of JS hooks for the bits that truly need to happen on the client for a good experience: TZ conversion, countdown timer, table sorting, Chart.js rendering. No framework needed.

The user doesn't notice if a transition takes 100ms because LiveView is fetching an HTML diff from the backend, or 100ms because React is doing an AJAX query to a JSON API, it's the same end result.
