Installation & setup

Medialibrary can be installed via composer:

$ composer require spatie/laravel-medialibrary

Next, you need to register the service provider:

// config/app.php
'providers' => [
    ...
    Spatie\MediaLibrary\MediaLibraryServiceProvider::class,
];

And publish and run the migration:

$ php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="migrations"
$ php artisan migrate

Publishing the config file is optional:

php artisan vendor:publish --provider="Spatie\MediaLibrary\MediaLibraryServiceProvider" --tag="config"

The config file contains a number of default values:

return [

    /*
     * The filesystems on which to store added files and derived images by default. Choose
     * one or more of the filesystems you configured in app/config/filesystems.php
     */
    'defaultFilesystem' => 'media',

    /*
     * The maximum file size of an item in bytes. Adding a file
     * that is larger will result in an exception.
     */
    'max_file_size' => 1024 * 1024 * 10,

    /*
     * This queue will used to generate derived images.
     * Leave empty to use the default queue.
     */
    'queue_name' => '',

    /*
     * The class name of the media model to be used.
     */
    'media_model' => Spatie\MediaLibrary\Media::class,

    /*
     * When urls to files get generated this class will be called. Leave empty
     * if your files are stored locally above the site root or on s3.
     */
    'custom_url_generator_class' => null,

    /*
     * The class that contains the strategy for determining a media file's path.
     */
    'custom_path_generator_class' => null,

    's3' => [
        /*
         * The domain that should be prepended when generating urls.
         */
        'domain' => 'https://xxxxxxx.s3.amazonaws.com',
    ],
];

Finally you should add a disk to app/config/filesystems.php. All files added to the media library will be stored on that disk, this would be a typical configuration:

return [
    ...
    'disks' => [
        'media' => [
            'driver' => 'local',
            'root'   => public_path('media'),
        ],
    ... 
];   

The package will add a .gitignore file to the directory where the media will be stored. Using another versioning sytem than git? Don't forget to ignore the directory of your media disk.

If you are planning on working with image manipulations it's recommended to configure a queue on your service and specify it in the config file.
