Over at Laravel News Povilas Korop wrote a nice tutorial on how to use our medialibrary (we released a new major version a couple of days ago).

By default, the Laravel registration form contains only the name, email, and password, but often it’s useful to allow the user to upload a photo or an avatar. In this tutorial we will show you an easy way to add it, using Spatie’s Media Library package.

It's a good tutorial but there's a few things not mentioned. At the end of the post you'll see this line of code:

Auth::user()->getMedia('avatars')->first()->getUrl('thumb');

That can be written a bit shorter as :

Auth::user()->getFirstMediaUrl('avatars', 'thumb');

The new v7 of the medialibrary has a new feature called "single file collections", which is just perfect for this example. Take a look at the docs: https://docs.spatie.be/laravel-medialibrary/v7/working-with-media-collections/defining-media-collections#single-file-collections
