I use .net mvc with a razor templating engine. But this can be used with any backend.

It makes it super easy for me to maintain all my UX in server-rendered HTML templates. I get a clean SPA with super high development efficiency with MINIMAL javascript.

The best part was I could hire any developer and they know how to work in basic HTML/JS/CSS.

Edit: Reading more, I might need to spend time looking into HTMX/Hotwire as a replacement for PJAX at some point.
