I went with SSR for a new project started 2025Q4. I'm not against React, but when I have to make an SPA (or very interactive component in an SSR app) I much rather use Elm.

In order to do the JS that I have to do with an SSR app I went with Alpine.js. It reduces the JS I have to write and that fits my SSR approach.

It feels a bit like a modern jQuery to be honest: you cannot build whole apps with it, but just to sprinkle on top of an SSR it does really well.
