# Importing Modules {#sec-importing-modules}
|
|
|
|
Sometimes NixOS modules need to be used in configuration but exist
|
|
outside of Nixpkgs. These modules can be imported:
|
|
|
|
```nix
|
|
{ config, lib, pkgs, ... }:
|
|
|
|
{
|
|
imports =
|
|
[ # Use a locally-available module definition in
|
|
# ./example-module/default.nix
|
|
./example-module
|
|
];
|
|
|
|
services.exampleModule.enable = true;
|
|
}
|
|
```
|
|
|
|
The environment variable `NIXOS_EXTRA_MODULE_PATH` is an absolute path
|
|
to a NixOS module that is included alongside the Nixpkgs NixOS modules.
|
|
Like any NixOS module, this module can import additional modules:
|
|
|
|
```nix
|
|
# ./module-list/default.nix
|
|
[
|
|
./example-module1
|
|
./example-module2
|
|
]
|
|
```
|
|
|
|
```nix
|
|
# ./extra-module/default.nix
|
|
{ imports = import ./module-list.nix; }
|
|
```
|
|
|
|
```nix
|
|
# NIXOS_EXTRA_MODULE_PATH=/absolute/path/to/extra-module
|
|
{ config, lib, pkgs, ... }:
|
|
|
|
{
|
|
# No `imports` needed
|
|
|
|
services.exampleModule1.enable = true;
|
|
}
|
|
```
