Building npm package from git

[ilyakooo0]

Am I correct in understanding that there is no counterpart to nixpkgs.haskell.packages.ghcHEAD.callCabal2nix? Meaning, if I have an npm package managed by niv, I would have to manually generate a .nix file with npm4nix and track it in my repo?

I think it could be possible, but not implemented. Also NPM packages are mostly unfriendly to Nix and require some manual hacks anyway.
