Sort with entityTypeManager

Question

I'm running an app where I am searching for every nodes of a given content type.

$nids = \Drupal::entityTypeManager()
  ->getListBuilder('node')
  ->getStorage()
  ->loadByProperties([
    'type' => 'courses',
    'status' => 1,
]);

I'm searching for a way to sort the results among a custom field of my nodes.

EDIT: I do not understand what's going on. Thanks to @4k4, I wrote this query:

$query = \Drupal::entityTypeManager()
    ->getListBuilder('node')
    ->getStorage()
    ->getQuery();
$query->condition('type', 'post');
$query->condition('status', 1);
$query->condition('field_category', $k);
$query->sort('field_ordering', 'ASC');

$nids = $query->execute();
$nids = Node::loadMultiple($nids);

A var_dump on $r[1] prints nothing. Same for $r[2]. But $results contains my results. What's going on ? The sorting doesn't work by the way.

Answer 1

The change record says if you have entityTypeManager injected, use

$query = $this->entityTypeManager->getStorage('node')->getQuery();

For non-OOP code, $query = \Drupal::entityQuery(); is not deprecated and can still be used.

The linked example for sorting an entity query by using $query:

$query->condition('type', 'blog_post')
  ->sort('field', 'DESC');
$nids = $query->execute();
