This in-depth post explores how component-based design (CBD) is evolving into a core UI strategy in Drupal, especially with the Single Directory Components (SDC) now baked into Drupal core (as of 10.3) and variant support introduced in 11.2. Ala Batayneh of Vardot outlines the principles of CBD—modularity, reusability, and scalability—and provides a hands-on walkthrough using SDC, Twig, and YAML to build dynamic UI components.

The article highlights key tools like Emulsify, UI Patterns, and Storybook, as well as Vardot's own Varbase CBD and Varbase Storybook tools, which streamline component workflows. Also notable is the AI-assisted prototyping direction for Drupal CMS in 2025. Designers and developers are encouraged to adopt a component-first mindset for faster, more consistent, and maintainable Drupal theming.
