To install through Composer, by run the following command:
composer require nwidart/laravel-modules
The package will automatically register a service provider and alias.
Optionally, publish the package's configuration file by running:
php artisan vendor:publish --provider="Nwidart\Modules\LaravelModulesServiceProvider"
By default the module classes are not loaded automatically. You can autoload your modules using psr-4. For example :
{
  "autoload": {
    "psr-4": {
      "App\\": "app/",
      "Modules\\": "Modules/"
    }
  }
}
Tip: don't forget to run composer dump-autoload afterwards
