Module Development

Render Pipeline for Drupal 8, 9, and 10

This tutorial looks at the steps that Drupal goes through to obtain a render array for an incoming HTTP request, transform the render array into HTML, and then return it to your browser. We provide an outline of the process and links to resources for more in-depth information. We also take a more thorough look at the HtmlRenderer which converts a render array into HTML. Knowing how the render arrays you write in your code are ultimately used can help you optimize Drupal's Render API to describe your module's content.
