Problem
You want to copy a third party package's assets to your application.
Solution
Use the php artisan asset:publish
command.
$ php artisan asset:publish cool-package
This copies the assets from the third party package into your application's public/packages/cool-package
directory, making them available in the web space.
Discussion
For non-Laravel packages you may need to specify the path.
$ php artisan asset:publish cool-package --path=/package/dir
For workbench packages, you can simply specify the workbench name.
$ php artisan asset:publish --bench=cool-package
