[Nix-dev] Build a default.nix for a project with node.js and python dependencies

[zimbatm]

I don't think there is an official list. Here is the ones I know of:

Go/GOPATH: go2nix
Ruby/Rubygems: bundix
Java/Maven: mvn2nix-maven-plugin
Node/npm: npm2nix (multiple implementations)
Haskell/Cabal: cabal2nix

And I think there are some for Perl/CPAN, Ocaml/??? and .NET/Nuget too. The
manual is supposed to cover each developer environment for each language.

It would be nice if we could come up with a universal XXX2nix that has a
unified interface, but then it's probably a lot of work to find the lowest
common denominator. All of those tools also generate different nix outputs,
some just generate the repository metadata, some also generate an
accompanying default.nix.
