drupal 8 get all nodes of type

To get all nodes of a specific type in Drupal 8, you can use the EntityQuery class provided by Drupal. Here's an example code snippet that demonstrates how to achieve this:

<?php
// Load the necessary Drupal functions and classes.
use Drupal\Core\Entity\EntityTypeManagerInterface;

// Get the entity query service.
$entityTypeManager = \Drupal::entityTypeManager();
$nodeStorage = $entityTypeManager->getStorage('node');

// Define the node type you want to retrieve.
$nodeType = 'your_node_type';

// Create the entity query to retrieve nodes of the specified type.
$query = $nodeStorage->getQuery()
  ->condition('type', $nodeType);

// Execute the query and get the result.
$nids = $query->execute();

// Load the nodes based on the retrieved IDs.
$nodes = $nodeStorage->loadMultiple($nids);

// Loop through each node and perform your desired operations.
foreach ($nodes as $node) {
  // Your code here.
}

Make sure to replace 'your_node_type' with the actual machine name of the node type you want to retrieve. You can find the machine name of a node type by navigating to admin/structure/types in your Drupal site's administration area.

By using this code snippet, you will be able to retrieve all nodes of a specific type in Drupal 8.
