Interesting take. I’m an Elixir fanboy because I find LiveView to be very slim. You’re just sending state diffs over WebSocket and updating the DOM with MorphDOM. The simplicity is incomparable to state of the art with JavaScript frameworks in my humble opinion.

That seems more complicated than jQuery

I'd use something like a lightweight python framework (take your pick) and pair it with htmx. You can run that on low powered hardware or a cheap VPS. I can't even dev elixir on my N100 minipc, it's too demanding. Otherwise Python and SolidJS or Preact will work perfectly for a SPA.
