Check the fully-undocumented hinc-to-Haskell transpiler.
Discussions as issues are also welcome.
That part is actually quite cool. The whole transpiler is developed using a usual stack of megaparsec to parse hinc code and haskell-src-exts to pretty print Haskell code. All of this, in addition to the front-end developed with Miso, is compiled to a single JavaScript file. Really, completely serverless!
