Nixpkgs: Node2nix doesn't support the `nodejs-13_x` packageset

[NinjaTrappeur]

Describe the bug
Node2nix doesn't support the nodejs-13_x packageset introduced by https://github.com/NixOS/nixpkgs/pull/71799.

Currently, some manual intervention is required to update the nodejs packages besides running pkgs/development/node-packages/generate.sh. See https://github.com/NixOS/nixpkgs/pull/78037/files

We need to update node2nix to handle this new packageset. This issue will be used to track the progress.

TODO

We could fork node2nix to nix-community and applied the changes required. I am not overly familiar with nodejs and its ecosystem though.

[NinjaTrappeur]

Yes, I think it would make sense.

I also think we mostly need somebody taking ownership of the nixpkgs nodejs packageset. I'm not really familiar with this environment nor up to this task.

If nobody shows up, maybe dropping the whole packageset from nixpkgs and rather use a per-software derivation fetching its own deps might make sense.

[Mic92]

No. I would not drop the whole package set. Having per-software derivations would add way to many generated node packages into nixpkgs since the node dependency graphs are insanely large.

[asymmetric]

We could also fork it and find a maintainer after the fact, and in the meantime apply the patches that we know we want.

Or is there something to lose in doing that?

[Mic92]

@asymmetric No. Are you up for the task? You can ask @zimbatm on #nix-community regarding creating repositories in nix-community.

[Mic92]

I created the fork here: https://github.com/nix-community/node2nix

[NinjaTrappeur]

Just saw that, I updated the first post. Thanks!

I'm going to update nixpkgs with it now.

[Mic92]

@NinjaTrappeur I am already in the process of doing so. Someone also broke the update script, which I am about to fix.

[asymmetric]

Is there anything left to do here?

[NinjaTrappeur]

Oops, I forgot to follow through this one.

The required changes have been merged to node2nix and a new 1.8.0
release has been issued. I just checked the current master, we the
various packageset have been regenerated.

We still did not adressed who/what(bot?) should be responsible to run
the generate.sh script periodically

That said, I think we're good for this issue. Closing.
