At DrupalCon Baltimore, I presented a session on how front-end developers can effectively debug Drupal 8. The session explored some of the challenges front-end developers face getting data from Twig templates and PHP files.
The goal was to distill the vast amount of information available into the most useful tools and techniques. Each one is illustrated with a video that includes relevant use-cases and references any dependencies.
Highlights include Drupal Console, error logs, browser tricks, interactive IDE debugging, Twig debugging and variable inspection, modules to help with development, and more.
