Starterkit Theme in Drupal 10: Implementing a Better Starting Point for Your Theme

Creating a custom theme in Drupal has always been a core part of building a unique digital experience. With Drupal 10, theming has become more streamlined and developer-friendly, thanks to the introduction of the Starterkit Theme. This new approach replaces the older Classy theme and offers a more modern, flexible foundation for building your custom theme.

In this blog, we’ll explore what the Starterkit Theme is, how it improves the development workflow, and why it’s a game-changer for Drupal theming.

What is the Starterkit Theme?

The Starterkit theme in Drupal 10 is a theme generator that creates a copy of the default theme, allowing developers to modify and extend it without impacting the original base theme. Unlike sub-theming, which inherits everything from a base theme, Starterkit gives you a standalone theme to work with — making it easier to customize and future-proof.

This approach eliminates the reliance on core themes for ongoing updates, giving developers complete control over their theme’s structure and styles.

Why Use the Starterkit Theme?

  1. Full Control & Independence: Since Starterkit copies the entire theme, developers can freely modify templates, CSS, and libraries without worrying about future core updates overwriting changes.
  2. Up-to-Date Best Practices: The generated theme includes modern practices and components, aligning with Drupal’s evolving architecture.
  3. Simpler Maintenance: By decoupling from core themes, maintenance becomes easier — you don’t have to track changes in the base theme after a Drupal update.
  4. Faster Development: With a ready-made, flexible starting point, developers can skip repetitive setup tasks and dive straight into customization.

How to Generate a Starterkit Theme

Creating a Starterkit theme is straightforward. Here’s how to do it:

  1. Navigate to Your Drupal Root Directory:
cd /var/www/html
  1. Run the Theme Generation Command:
drush theme:generate starterkit my_custom_theme

Replace my_custom_theme with your preferred theme name.

  1. Enable the New Theme:
drush theme:enable my_custom_theme
drush cache:rebuild

That’s it! You now have a fully independent theme ready for customization.

Best Practices for Using Starterkit

  • Keep Your Theme Modular: Organize components, templates, and styles logically to make ongoing updates easier.
  • Follow Drupal Coding Standards: Adhere to best practices to maintain compatibility and avoid technical debt.
  • Leverage Twig Templates: Use Twig to control markup output and keep your templates clean and maintainable.

The Starterkit Theme in Drupal 10 is a significant step forward, simplifying the development process while empowering developers with more freedom and flexibility.
