After a few failed attempts at deploying my Elm application on NixOS, I'm trying elm2nix, which some NixOS and Elm users created to attempt to solve some of the issues that I ran into earlier today. Elm tries to write to $HOME, which NixOS doesn't like. I typically prefer to avoid things like cabal2nix, elm2nix, node2nix because I don't like the workflow that they suggest, but I'm so eager to deploy this application, that I'm trying it.
