Module Development

Concept: Asset Libraries for Drupal 8, 9, 10, and 11

Asset libraries in Drupal associate CSS and JavaScript files with components, which enhances performance because the assets will only be loaded when they're needed.

In this tutorial, we'll:

  • Define asset libraries and their purpose.
  • Learn how to define an asset library in a module.
  • Examine how asset libraries attach to components.

By the end of this tutorial, you should understand how asset libraries optimize resource loading and facilitate component-based development in Drupal.
