Drupal 8: delete all nodes of the same type

Question

I have a need to remove all nodes of the same type in Drupal 8 (there are over 7k of nodes).

It wouldn\'t be a problem for Drupal 7 (DB query + node_del

Answer 1

Well, the answer lies on the surface:

$types = array('my_content_type_name');

$nids_query = db_select('node', 'n')
->fields('n', array('nid'))
->condition('n.type', $types, 'IN')
->range(0, 500)
->execute();

$nids = $nids_query->fetchCol();

entity_delete_multiple('node', $nids);

I advice you to use "range" and some sort of "batch" (or just re-run the code multiple times), because it's a very fat operation (500 nodes per operation is ok for 256MB).

To execute this code you can either write custom module OR use the devel module: https://www.drupal.org/project/devel

After installation go to yoursite_address/devel/php and execute php code there.
