Drupal 8 Theme System: The Backend of Frontend

If you develop with Drupal, chances are you've worked with Drupal's theme system, whether you knew it or not. With Drupal 8 out, what better time to learn more about the Drupal 8 theme system?

The theme system in Drupal spans both module development and theme development. The main responsibilities of the theme system are to prepare and output markup and other data, and to allow for overrides. The Drupal 8 theme system brings many changes including the Twig templating engine, automatically escaped markup for increased security, changes to theme suggestions, new base themes in core, and more.

Scott Reeves, Team Lead at Digital Echidna, and Drupal 8 theme system co-maintainer and provisional core committer will guide you through Drupal 8’s theme system. The webinar will cover important differences from Drupal 7 and also walk through the internals of different aspects of the theme system and how they might affect your day-to-day work with Drupal. Topics will include:

  • An overview of the important changes to the theme system from Drupal 7 to Drupal 8
  • How to use theme hook suggestions to cut down on custom code and create more flexible and reusable components
  • Phases of the theme and render systems and where you can step in to alter things
  • Debugging tips and Twig magic
