Documentation: How to use pkgs.yarn2nix-moretea.linkNodeModulesHook

[l0b0]

Problem

I can't find any usage documentation or examples other than this comment:

This can be used as a shellHook in mkYarnPackage. It brings the built node_modules into the shell-hook environment.

How is it meant to be used in mkYarnWorkspace?

Basically, how do you set up a Nix shell with Yarn module executables on $PATH?

Proposal

I haven't touched this for a while. I recommend looking at npmlock2nix v2, if you can switch back to npm: https://github.com/nix-community/npmlock2nix/blob/master/API.md

Thanks for the tip, @zimbatm! I might look into that (using synp --source-file yarn.lock to convert the lock file) once it's more appropriate for my use case:

• I don't know whether it puts node_modules/.bin on the path
• It's not in nixpkgs
• It only provides niv install instructions, but I'd rather not pull in yet another tool
