Usage

    'providers' => [
        // ...
        LukeTowers\Purifier\PurifierServiceProvider::class,
    ]

Find the aliases key in app/config/app.php.

    'aliases' => [
        // ...
        'Purifier' => LukeTowers\Purifier\Facades\Purifier::class,
    ]

Configuration

To use your own settings, publish config.

$ php artisan vendor:publish --provider="LukeTowers\Purifier\PurifierServiceProvider"
