Deleting an entity

In this recipe, we will walk through deleting an entity. Deleting an entity allows you to remove an entity from the database so that it no longer exists.

How to do it…

1. Create a delete method in the ArticleController controller in your module that has a parameter for the node entity object that will be provided by a route parameter:

   <?php

   namespace Drupal\mymodule\Controller;

   use Drupal\Core\Controller\ControllerBase;

   use Drupal\node\NodeInterface;

   use Symfony\Component\HttpFoundation\JsonResponse;

   use Symfony\Component\HttpFoundation\Request;

   class ArticleController extends ControllerBase {

     public function delete(NodeInterface $node):

       JsonResponse {

     }

   }

2. To delete an entity, you will invoke the delete method:

     public function delete(NodeInterface $node):

       JsonResponse {

      $node->delete();

     }

The delete method immediately removes the entity...
