How to load node by id in Drupal 8?

@wilmer.lemke 

In Drupal 8, you can load a node by its ID using the Node::load() method. Here is an example of how you can use this method:

1
2

$node = Drupal
odeEntityNode::load($nid);

Where $nid is the ID of the node you want to load.

Alternatively, you can use the entity_load() function, which allows you to load multiple nodes at once:

1

$nodes = Drupal::entityTypeManager()->getStorage('node')->loadMultiple([$nid1, $nid2, ...]);

Here, $nid1, $nid2, etc. are the IDs of the nodes you want to load. The function returns an array of nodes, indexed by their IDs.

Note that both of these methods will return a fully-populated node object, including all field values and other properties. If you only need a limited set of data for the node, you may want to consider using a custom query to retrieve the data from the database.

$nid = 123; // The ID of the node you want to load
$node = Drupal
odeEntityNode::load($nid);

if ($node instanceof Drupal
odeNodeInterface) {
  // The node was successfully loaded.
  // You can now access its properties and fields.
  $title = $node->getTitle();
  $body = $node->get('body')->getValue()[0]['value'];
  // ... other processing or rendering of node properties.
}
else {
  // The node with the given ID does not exist or was not loaded successfully.
  // Handle the error condition as needed.
}

In the above code, replace 123 with the actual ID of the node you want to load. After loading the node, you can then access its properties and fields using the appropriate methods, such as getTitle() or get().
