Kudos to Kofi for a nice project and a good write-up :+1: :)

Since you're not planning on continue the project, and are interested on 'Elm on the server', you might look at Purescript, which has a similar syntax, and compiles to Javascript, and also the BEAM: https://github.com/purerl

There are also C++ and C backends at https://github.com/andyarvanitis/purescript-native and https://github.com/pure-c/pure-c

If having a JS compile option is not a requirement, there are 2 more Ocaml/ReasonML-like BEAM laguages, https://github.com/alpaca-lang and https://github.com/lpil/gleam

(I'm kinda partial to Gleam, it seems really clean)
