nwidart/laravel-modules is a Laravel package which created to manage your large Laravel app using modules. Module is like a Laravel package, it has some views, controllers or models. This package is supported and tested in Laravel 5.
This package is a re-published, re-organised and maintained version of pingpong/modules, which isn't maintained anymore. This package is used in AsgardCMS.
With one big added bonus that the original package didn't have: tests.
