I'm starting to come around to this opinion. I was originally quite bullish on FastHTML but I am starting to feel a little bit lost with all the abstraction and indirection.
I was initially attracted by the idea that I could replace the traditional HTML, CSS, Javascript , Python (backend) project entirely in Python, but it's starting to feel like the original mix of languages might have been the simplest option all along, particularly with GenAI tools
Actually the abstractions are much thinner than with something like NextJS imo. It all comes down to what you are comfortable with. If you learned web dev in the React era, this approach feels very odd, but if you come from something like Ruby on Rails, this actually quite intuitive and not a lot of abstraction (see Jeremy‘s comment in this thread).
I personally like to stay with normal HTML and FrankenUI instead FastHTML instead of MonsterUI tho.
While I sort of agree with your and the parent post (I have always liked Flask with simple Janga templates) I just put a task on my personal schedule to try a project with FastHTML and MonsterUI. A long time ago I found studying JH’s abstractions for deep learning very useful, even though I did all my real work in TensorFlow. It will probably be the same with FastHTML and MonsterUI: I am likely to just use it for one fun project, but I am sure to learn a few things. And, I might use it long term. A no-lose situation because I am retired and my time is my own.
