I have almost zero experience using nix, so I will just list a few topics that may or may not be related:
- Zig2nix: nix flake for packaging, building and running Zig projects
- Baby’s first Zig project (w/ Bonus Nix-Zig flake based dev shell)
- zon2nix - Convert the dependencies in `build.zig.zon` to a Nix expression
Hopefully someone with more experience using nix can help you.
