Dries Buytaert Replaces JavaScript with htmx for Infinite Scroll on Photo Stream
Dries Buytaert recently revisited the infinite scroll feature on his Drupal-powered photo stream, replacing a previous custom JavaScript setup with a cleaner implementation using htmx.
The updated approach leverages htmx's HTML attributes such as hx-get and hx-trigger to fetch and insert content as users scroll, removing the need for direct JavaScript manipulation. This change reduced the client-side code significantly, while keeping the PHP controller that delivers batches of images. Dries also introduced a prefetch strategy by triggering the next load a few images before the end, ensuring seamless scrolling.
Although htmx adds more weight than his earlier custom JavaScript, Dries found the declarative approach both practical and satisfying. He noted that features like this reflect Drupal's continued evolution, quietly enhancing developer experience without being disruptive. The project demonstrates how Drupal’s integration with tools like htmx can modernize user interactions while reducing code complexity.
