Drupal has long offered multiple ways to build dynamic user interfaces: Form API AJAX, BigPipe, and fully decoupled frontends with React or Vue. Each approach solved specific problems, but often at the cost of complexity, heavy JavaScript, or difficult maintenance.
With Drupal 11.3, HTMX becomes a first‑class citizen in core, offering a modern alternative: rich, reactive UX built primarily with HTML and server-side rendering, while dramatically reducing JavaScript overhead.
