Have you looked into mix2nix at all?

Yes, I know mix2nix. Creating and using fetchMixDeps is simply a matter of preference.

When using mix2nix, we have to create deps.nix which is generated from mix.lock. In this way, we can have more fine-grained cache control, but it'll create many nix expressions just for deps. That's not what I want.

I like the method used by fetchNpmDeps - treating all dependencies as a whole. so I create fetchMixDeps. In this way, although cache control is not that fine-grained, considering dependencies don't change frequently, I think this is acceptable.

Understood and makes sense! I'm learning nix on Elixir and your repo helped a lot - thanks
