How can I loop through all article content types and get the content of each

I created a new article content and am overriding that by creating a template for it (ie: node–4.html.twig).

Then inside this template, I want to loop through all nodes that belong to article content type; and to achieve that, I created my .theme file and added the following code based on the answer for this question here:

<?php   function capoeira_preprocess_page(&$variables) {   $articles = Drupal::entityQuery('node')->condition('type', 'article')->execute();   $nodes = DrupalnodeEntityNode::loadMultiple($articles);     $variables['articles'] = $nodes; } 

Inside the template I do have:

{{ kint(articles) }} 

inside my template and I go refresh the page I show article as NULL.

How do I loop through the articles?


None of the below work:

function capoeira_preprocess_page(&$variables) {   $articles = Drupal::entityQuery('node')->condition('type', 'article')->execute();   $nodes = DrupalnodeEntityNode::loadMultiple($articles);   $variables['name'] = $nodes; }  function capoeira_preprocess_node(&$variables){   $variables['name'] = 'My name comes here'; }  function capoeira_preprocess_node_article(&$variables){   $variables['name'] = 'My name comes here'; }
