Utility Types

Plugins can provide custom utility types for the Utilities section by creating a class that implements craft3:craft\base\UtilityInterface.

As a convenience, you can extend craft3:craft\base\Utility, which provides a base utility type implementation.

You can refer to Craft’s own utility classes for examples. They are located in vendor/craftcms/cms/src/utilities/.

#Registering Custom Utility Types

Once you have created your utility class, you will need to register it with the Utilities service, so Craft will know about it when populating the list of available utility types:

namespace mynamespace;

use craft\events\RegisterComponentTypesEvent;
use craft\services\Utilities;
use yii\base\Event;

class Plugin extends \craft\base\Plugin
{
    public function init()
    {
        Event::on(
            Utilities::class,
            Utilities::EVENT_REGISTER_UTILITY_TYPES,
            function(RegisterComponentTypesEvent $event) {
                $event->types[] = MyUtility::class;
            }
        );

        // ...
    }

    // ...
}
