Loved HTMX when I was writing code by hand. For my side project, I'm using Inertia so it acts like a request-response cycle, Vue+TS and Django+Pydantic so any hallucinations are caught by type checkers at both sides.

I forgot Django! Hmm. Thanks for the reminder.

And I hadn't heard of Inertia. Checking it out now.
