Overview of this book

Drupal is an open source content management system trusted by governments and organizations around the globe to run their websites. It brings with it extensive content authoring tools, reliable performance, and a proven track record of security. The community of more than 1,000,000 developers, designers, editors, and others have developed and maintained a wealth of modules, themes, and other add-ons to help you build a dynamic web experience. Drupal 8 is the latest release of the Drupal built on the Symfony2 framework. This is the largest change to the Drupal project in its history. The entire API of Drupal has been rebuilt using Symfony and everything from the administrative UI to themes to custom module development has been affected.

It will provide a clear and concise walkthrough of the more than 200 new features and improvements introduced in Drupal core. In this book, you will learn advanced site building techniques, create and modify themes using Twig, create custom modules using the new Drupal API, explore the new REST and Multilingual functionality, import, and export Configuration, and learn how to migrate from earlier versions of Drupal.

Preface

Summary


With previous versions of Drupal, in order to get deep insights into what was going on, you would need to install tools like Xdebug or XHProf. Without those, you were limited to what you could do with printing variables to the screen using print_r(), kpr(), dpm() with the Devel module. First, we covered installing the Devel module and using the new Kint module. This allows us to view detailed information about the backtrace as well as any object or Twig template variable. Next, we went over how to use the Web Profiler bundle to get detailed information about each request. This includes:

  • Information about the request and route
  • The timeline of each component used in building the page
  • A list of all queries run on the page
