Add Grayjay.Desktop.Web Flake

[elanorg]

I've written and tested a flake.nix for Grayjay.Desktop.Web

It's not quite up to my standards, but it evaluates as expected. You can verify this to your own satisfaction by running nix build ./Grayjay.Desktop.Web from the repo's root and digging through the result symlink. My intentions are to import this derivation as-is into the final packaged output of Grayjay.Desktop as a whole, a la cp -r ${pkgs.grayjay-desktop-web} $out/bin/wwwroot.

Tip

To the maintainers:

I'll be following the "branch stacking" convention for these flakes, so it may be more convenient to merge a different branch, which should be mentioned below.

Note

Alejandra, my formatter of choice, only added support for alejandra.toml in v3.1.0

Caution

Concerning $out/lib:

pkgs,lib.buildNpmPackage includes node_modules in $out/lib, which takes up an obscene amount of space and is afaict totally unnecesary. fixupPhase is a hacky workaround for this and I totally intend to fix it properly.

On further consideration, I think it wise to restructure the stacked-branch scheme I had laid out. There will need to be a flake.nix in this repository's root, but there is no branch on which it can live and thus be merged into master.

I'm closing this in favor of a different branch naming scheme is all.

EDIT: I had to draw the whole thing out on a newly-acquired whiteboard, but I had my mental model backwards the entire time. This branch is fine as it is.

Which is a little embarrassing, to be honest.
