Dev webserver fails to start on nixos (broken Pipe, esbuild goroutines)

[Elec3137]

Describe the bug

Mostly, pnpm run dev doesn't work, forcing me to iterate on the app by doing:
pnpm run build && python -m http.server -d dist/

(within nix shell nixpkgs#nodejs nixpkgs#pnpm and after running pnpm i)

output of `pnpm run dev`

Reproduction

1. use nixos
2. make sure programs.nix-ld.enable = false;
3. nix-shell -p nodejs pnpm --run "pnpm iinstall && pnpm run dev"

Expected behavior

dev server shouldn't crash

Platform and versions

1. NixOS 26.05 (Yarara) x86_64 (rev: 6c9a78c09ff4d6c21d0319114873508a6ec01655)
2. Chromium: 145.0.7632.159 (Official Build, ungoogled-chromium) (64-bit)
3. rev: 7b76e27e8f914c78ef1dd7740b48b5d7526e5d93
4. federated.nexus

Additional context

pnpm remove wrangler had no visible effect. Also tried rm -r dist/ .wrangler/ node-modules/, moving the project to /tmp, etc.

This was discussed in the sable space, this is related to wrangler's workerd's glibc requirements and where it looks for it on nix systems.

Current workaround is to enable nix-ld system wide on nixos setups to get around this. I will look into a solution for this, as wrangler is not a runtime dependency.

sorry then, my bad.

You good!!

[parfaitcake]

I got around it by using this nix shell personally:

{
  pkgs ? import <nixpkgs> { },
}:

(pkgs.buildFHSEnv {
  name = "dev-env";
  targetPkgs =
    pkgs: with pkgs; [
      nodejs_24
      pnpm
      libatomic_ops
      stdenv.cc.cc
    ];
  runScript = "bash";
}).env

no need to enable nix-ld system wide, it'd be great if someone made a proper flake with a dev shell for Sable!
