In reply to @hexa:lossy.network
so sorry, but I'm running into another problem I don't understand

In reply to @lily:lily.flowers
npm workspaces. I haven't done a deep dive yet to figure out why npm gets too spooked to use the cache when workspaces are involved like this. The method to specify a workspace package like from https://github.com/NixOS/nixpkgs/pull/218923 may help

In reply to @hexa:lossy.network
so another modification to build-npm-package? 😄

In reply to @hexa:lossy.network
there is the django-hijack issue above, if you want to knock yourself out 😄

it's an unlanded PR rebased and locally updated to a newer version during rebase 🤡

If you want to test it yourself, add a npmWorkspace argument with the npm workspace package you are wanting to build and apply this diff locally:
