HTMX has steadily risen among JavaScript projects since its release in recent years, gaining more new stars on GitHub in 2024 than React. Now HTMX is integrated into Drupal core and forms the basis of a subsystem that will replace our jQuery based Ajax API.

HTMX is both simple and powerful. It enables any HTML element to become a hypermedia control, enhancing interaction with the site. HTMX uses HTML as its data structure enabling replacement or addition of new markup anywhere on the page.

Drupal 11.3 shipped with a new subsystem that allows straightforward integration of HTMX into Drupal. This session will introduce this subsystem and the theory and practice of hypermedia web applications built with HTMX. We will walk through examples of how you can start using HTMX in your own projects and also look at the current status of the community initiative to replace the Ajax API.
