I've only recently come back to the world of web after doing mostly devops/backend stuff. While getting on the JS framework treadmill might get other people hired, staying server side + Bootstrap kept me sane and productive. The only place where I spent an innovation token[0] was on htmx and so far it's been absolutely worth it. [0]: https://boringtechnology.club
what backend do you use?
But if I was just starting out trying to learn a web stack like GP, I'd say absolutely don't pick FastAPI, use Django + Postgres + Bootstrap + htmx and you'll be happy.
