Usage

To use the HTMLPurifier Service Provider, you must register the provider when bootstrapping your Laravel application. There are essentially two ways to do this.

For Laravel 5.0 to 5.4:

Find the providers key in config/app.php and register the HTMLPurifier Service Provider.

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

Find the aliases key in config/app.php.

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

For Laravel 5.5+:

The service provider will be auto-discovered. You do not need to add the provider anywhere.

Configuration

To use your own settings, publish config.

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