Reusable Nix flake for official Node.js LTS binaries.

It packages the upstream Node release archives directly and exposes both a moving current-LTS package and an exact versioned package attr for downstream pinning.

• packages.<system>.default
• packages.<system>.nodejsLts
• packages.<system>.nodejs_v24_14_0
• apps.<system>.default
• overlays.default

The exact-version attr updates when version.json changes.

• x86_64-linux
• aarch64-linux
• x86_64-darwin
• aarch64-darwin

Windows is intentionally out of scope for v1.

Run Node directly:

nix run github:your-org/nodejslts-nix

Install the current LTS package:

nix profile add github:your-org/nodejslts-nix

Use the exact pinned version:

nix profile add github:your-org/nodejslts-nix#nodejs_v24_14_0

Use as a flake input:

{
  inputs.nodejslts-nix.url = "github:your-org/nodejslts-nix";

  outputs = { self, nixpkgs, nodejslts-nix, ... }:
    let
      system = "x86_64-linux";
      pkgs = import nixpkgs {
        inherit system;
        overlays = [ nodejslts-nix.overlays.default ];
      };
    in {
      devShells.${system}.default = pkgs.mkShell {
        packages = [ pkgs.nodejsLts ];
      };
    };
}

Enter the maintenance shell:

nix develop

Run the repo checks:

nix flake check

Check for a newer LTS release:

nix develop --command ./update.sh

Update to the latest LTS release:

nix develop --command ./update.sh --update

version.json is the source of truth for:

• the pinned Node version
• the LTS codename
• the exact package attr name
• the upstream asset name per platform
• the Nix fetch hash per platform

The update workflow regenerates version.json from the official Node release index and SHASUMS256.txt.
