• Create and customize impressive Drupal 8 modules to extend your website's functionalities
• Implement efficient data management and data security by creating dedicated modules
• Stay up to date with the changes introduced in the new Drupal 8 release

Drupal 8’s release cycle allows for new functionality to be introduced at a much faster pace. However, this also means code deprecations and changing architecture that you need to stay on top of. This new edition of Drupal 8 Module Development has been fully updated to reflect the new functionality introduced in Drupal versions up to and including 8.7.

Starting with an introduction to Drupal 8 architecture and its subsystems, this book will guide you in creating your first module with basic functionality. You’ll work with Drupal logging and mailing systems, learn how to output data using the theme layer, and work with menus and links programmatically. This Drupal book demonstrates how to work with different kinds of data storages, create custom entities and field types, and leverage the Database API for lower level database queries. Furthermore, you’ll learn how to introduce JavaScript into your module, work with different file systems, and ensure that the code you write works on multilingual sites. Toward the end, the book will help you work with Views, write automated tests for your functionality, and write secure code in general.

By the end of the book, you’ll have learned how to develop your own custom module that can provide complex business solutions, and who knows, maybe you’ll even contribute it back to the Drupal community!
