Use yarn import to work with package-lock.json projects

[expipiplus1]

Thanks for this very useful program!

At the moment I've been having good success using yarn2nix instead of node2nix by running yarn import to generate a yarn.lock file from package-lock.json. (I think another tool to do this is synp but I've not tried it).

I wonder if it would be possible to use this functionality in this project in a less ad-hoc way than I've currently been doing.

I'd be pretty interested in this. You can probably just wrap yarn2nix in a function which takes in the package-lock.json & transforms it with yarn import via a derivation

This would be very cool, but I'm running into some issues that seem to come from not being able to download files from npm:
