Elixir packaging for nixpkgs

I am looking to package Linkhut which is an elixir/phoenix application using mix. I was wondering if there are any existing packages I can use as examples/best way to approach this. I saw there are a variety of mix2nix style approaches but I am not sure if they are suitable for nixpkgs or which one I might use.

I know nothing about elixir, but pleroma is an elixir application packaged in nixpkgs, you may check it out.

There is also the ongoing effort to package Mobilizon, a web application
with an Elixir backend: https://github.com/NixOS/nixpkgs/pull/119132

I have packaged my (relatively simple) phoenix application
here

It is heavily inspired by how
pleroma
is packaged, which is already mentioned here.

I’m also looking for help with this at Packaging claperco/claper software

Thanks for all the examples! Gonna take a shot at packaging linkhut once thanksgiving is over.
