hyprland-wiki/pages/Nix/Hyprland on NixOS.md

The NixOS module enables critical components needed to run Hyprland properly,
such as: polkit,
[xdg-desktop-portal-hyprland](https://github.com/hyprwm/xdg-desktop-portal-hyprland),
graphics drivers, fonts, dconf, xwayland, and adding a proper Desktop Entry to
your Display Manager.

Make sure to check out the options of the
[NixOS module](https://search.nixos.org/options?channel=unstable&from=0&size=50&sort=relevance&type=packages&query=hyprland).

{{< hint title=Note >}}
- *(Required) NixOS Module*: enables critical components needed to run Hyprland properly
- *(Optional) Home-manager module*: lets you declaratively configure Hyprland
{{< /hint >}}

{{< tabs "uniqueid" >}}

{{< tab "Nixpkgs" >}}

```nix
# configuration.nix

{pkgs, ...}: {
  programs.hyprland.enable = true;
}
```

This will use the Hyprland version that Nixpkgs has.

{{< tab "Flake package" >}}

{{< hint >}}
Please enable [Cachix](../Cachix) before using the flake package, so you don't
have to compile Hyprland yourself.
{{< /hint >}}

In case you want to use the development version of Hyprland, you can add it
like this:

```nix
# flake.nix

{
  inputs.hyprland.url = "github:hyprwm/Hyprland";
  # ...

  outputs = {nixpkgs, ...} @ inputs: {
    nixosConfigurations.HOSTNAME = nixpkgs.lib.nixosSystem {
      specialArgs = { inherit inputs; }; # this is the important part
      modules = [
        ./configuration.nix
      ];
    };
  } 
}

# configuration.nix

{inputs, pkgs, ...}: {
  programs.hyprland = {
    enable = true;
    package = inputs.hyprland.packages.${pkgs.system}.hyprland;
  };
}
```
Don't forget to change the `HOSTNAME` to your actual hostname!
