Abysmally slow `nuxt dev` on NixOS

[auctumnus]

Hi!

I tried to set up Prisma with Nuxt, but it appears to cause nuxt dev to be abysmally slow, even if it's not actually enabled as a module.

Fresh Nuxt project (808ms):

With "@prisma/nuxt": "^0.0.35" in dependencies and "@prisma/client": "^5.19.1", "prisma": "^5.19.1" in devDependencies (100203 ms, or nearly 2 minutes):

This is the flake.nix I'm using in both:

{
  inputs.pkgs.url = "github:NixOS/nixpkgs/nixpkgs-unstable";
  inputs.prisma-utils.url = "github:VanCoding/nix-prisma-utils";

  outputs =
    { pkgs, prisma-utils, ... }:
    let
      nixpkgs = import pkgs { system = "x86_64-linux"; };
      prisma =
        (prisma-utils.lib.prisma-factory {
          inherit nixpkgs;
          prisma-fmt-hash = "sha256-Lj0V8E9a+q6+PvCF2ARRs34n1Ls3vySVmtN1rxfltRg=";
          query-engine-hash = "sha256-1BwohGMohcS0rQkrbD+4ne63NOtlZnxLfYUEMrnbglg=";
          libquery-engine-hash = "sha256-WWE2c5Xjw+7wbeGcdX6UU8YzPeT1vZQxye/Mh8XFsCA=";
          schema-engine-hash = "sha256-y5zt3jlaIBoxNHcDitOkMfLd/5doCadVmUiE4bAM/MA=";
        }).fromNpmLock
          ./package-lock.json;
    in
    {
      devShells.x86_64-linux.default = nixpkgs.mkShell {
        buildInputs = with nixpkgs; [
          nodejs_22
          nodePackages_latest.prisma
          openssl_3_3
        ];
        shellHook = prisma.shellHook;
      };
    };
}

Is there anything else I can do to help debug this issue?

Hey there

Hey there @auctumnus , can you set the export variable and see which step is taking up most of your time? Also the same @Dzyanino.
