Ask HN: Any recommendation for minimalist web app language?

I'm planning to run personal pages on a Raspberry Pi 3+ and would like to program the whole website directly in some programming language that is fun to use and minimalist. I know Picolisp and might give it a try. I'm also aware of Hunchentot and Racket's web framework, as well as Gnoga for Ada, but they are not very minimalist. What other potentially interesting or "fun" language/framework combos are there?
