Great to see you around! (Thanks a lot for the node2nix contribution btw)
You might be aware of this issue #145432
a missing bin for nodePackages built with node16.
since 16 is lts, there are efforts to change the default node version from 14 to 16. My understanding is that the next node2nix version handles node 16 correctly.
Let me know if I can be of any help.
Thanks again!

@happysalada Yes I've added an option to handle Node.js 16.x out of the box. Some of the stuff that I need seems to work, but we still have to see how well the integration works.

I also intend make the modifications so that we can package for Node.js 16.x. We probably should start with a small set of packages first and then gradually expand it.

Amazing thanks! I think prettier was one of the problematic packages. If it works properly for prettier, then the potential problem might have been fixed.

Hi. Is there anything blocking updating to node2nix 1.10.0?

This fixes node2nix when using Node.js >= 15, right?
Since electron 14, which is the last version supporting Node.js 14, is now EOL (#166825), we should really try to get this merged.

What's blocking this?

I'm wondering why node2nix even on master of nixpkgs (a5774e7) is still 1.9.0 even though it claims to be 1.10.0.

nix-repl> pkgs.nodePackages.node2nix.version
"1.10.0"

nix-repl> node2nix
«derivation /nix/store/ipkkiavdmj2m8m9zxdkjsd8kfxqdj27c-node2nix-1.10.0.drv»

nix-repl> :b node2nix
[62 copied (334.6 MiB), 79.6 MiB DL]

this derivation produced the following outputs:
  out -> /nix/store/nz0fw6vhdfhv45nzlxahp6383p3m9lyj-node2nix-1.10.0

But:

$ /nix/store/nz0fw6vhdfhv45nzlxahp6383p3m9lyj-node2nix-1.10/bin/node2nix --version
node2nix 1.9.0
$ /nix/store/nz0fw6vhdfhv45nzlxahp6383p3m9lyj-node2nix-1.10/bin/node2nix --help | grep nodejs
  -4, --nodejs-4                Provides all settings to generate expression for usage with Node.js 4.x (default is: Node.js 12.x)

  --pkg-name NAME               Specifies the name of the Node.js package to use from Nixpkgs (defaults to: nodejs)

It doesn't even show the --nodejs-16 option.

I'm wondering why node2nix even on master of nixpkgs (a5774e7) is still 1.9.0 even though it claims to be 1.10.0.

That's because of the override in pkgs/development/node-packages/default.nix.

My suggestion would be something like this where we don't touch packages that aren't inside nodePackages: #170722
Note that it breaks their update scripts however.

I believe this is blocking fixing mongosh and pretty much all nodejs_16x packages.

It seems like it was approved but never merged, so this should be low-hanging fruit if the merge conflict isn't too difficult?

node2nix was already updated in #171195 as I understand it. This PR also regenerates a few of the packages not under pkgs/development/node-packages, but that may have already been done in separate PRs as well

I believe there are still some issues with node2nix and Node.js 16+ that will need to be fixed in svanderburg/node2nix first before some of those packages will work correctly. Mostly svanderburg/node2nix#236 (comment) and svanderburg/node2nix#293 I think

I believe this is blocking fixing mongosh and pretty much all nodejs_16x packages.

I don't think this is true -- node2nix still cannot output v2 lockfiles.

My mistake, I'm new to node/javascript on NixOS and just got here by attempting to connect to a mongo server using the mongo cli on nixos 😅
