+=nixpkgs= has pretty decent support for Elixir projects with some good helpers. In 2021 I tried an earlier incarnation of [[id:1d917282-ecf4-4d4c-ba49-628cbb4bb8cc][The Arcology Project]] in Elixir+Phoenix, got it working on my laptop but when time came to use Nix to put together a Docker container I couldn't get =ecto_sqlite3= to build. Since then, I have shipped a fully function [[id:arcology/fastapi][Arcology FastAPI]] prototype, but I am still quite interested in shipping this on the BEAM. Elixir is cool, and the [[id:20220225T175638.482695][Arcology Public Router]] could "just" be a =Phoenix.Plug=. Now that I have a proper database layer in the [[id:arcology/arroyo-page][Arroyo Arcology Generator]] many of the design shortcomings of the original Arcology Phoenix prototype can be worked around. I'll be writing a Content-Addressed Store, too, I think, for caching the pages.
