ez-configs flake-parts module provides a flexible framework for managing configurations across multiple systems using nixosSystem, darwinSystem (nix-darwin), and homeManagerConfiguration (home-manager), as well as exporting individual modules.

This module allows for defining configuration and module outputs in your flake, for use in nixos, nix-darwin and home-manager, using your directory structure. This results in 6 directories the module can use:

• nixosModules
• nixosConfigurations
• darwinModules
• darwinConfigurations
• homeModules
• homeConfigurations

Each .nix file, or a directory containing default.nix file gets included in the respective outputs. When building configurations, the default module (ie. <modulesDirectory>/default.nix or <modulesDirectory>/default/default.nix) is imported, unless importDefault is set to false for that user or host configuration. In case of home manager configurations, it also includes the darwin or linux modules depending on the system that configuration is built from.

If starting from scratch, you can use the template nix flake new --template github:ehllie/ez-configs inside the directory where you'd like to setup your flake.

Otherwise, to your flake inputs add:

ez-configs.url = "github:ehllie/ez-configs";

Inside your mkFlake add:

imports = [
  inputs.ez-configs.flakeModule
];

ezConfigs.root = ./.;

I also use this module in my own dotfiles.
