Remember NodeType from the preceding chapter, and, by now, you know the essentials of creating custom entity types. So, let's create our Importer type now. Like before, we start with the annotation part, which is this time a ConfigEntityType:
namespace Drupal\products\Entity;use Drupal\Core\Config\Entity\ConfigEntityBase;use Drupal\Core\Url;/** * Defines the Importer entity. * * @ConfigEntityType( * id = "importer", * label = @Translation("Importer"), * handlers = { * "list_builder" = "Drupal\products\ImporterListBuilder", * "form" = { * "add" = "Drupal\products\Form\ImporterForm", * "edit" = "Drupal\products\Form\ImporterForm", * "delete" = "Drupal\products\Form\ImporterDeleteForm" * }, * "route_provider" ...
