Book Description
With its latest release, Drupal 9, the popular open source CMS platform

apps with ease. This third edition of the Drupal Module Development
guide covers these new Drupal features, helping you to stay on top of
code deprecations and the changing architecture with every release.
The book starts by introducing you to the Drupal 9 architecture and its
subsystems before showing you how to create your first module with basic
functionality. You'll explore the Drupal logging and mailing systems,
learn how to output data using the theme layer, and work with menus and
links programmatically. Once you've understood the different kinds of
data storage, this Drupal guide will demonstrate how to create custom
entities and field types and leverage the Database API for lower-level
database queries. You'll also learn how to introduce JavaScript into
your module, work with various file systems, and ensure that your code
works on multilingual sites. Finally, you'll work with Views, create
automated tests for your functionality, and write secure code.
By the end of the book, you'll have learned how to develop custom
modules that can provide solutions to complex business problems, and who
knows, maybe you'll even contribute to the Drupal community!
