In Chapter 6, Data Modeling and Storage, and Chapter 7, Your Own Custom Entities and Plugin Types, we talked quite extensively about content entities and how they use fields to store the actual data that they are supposed to represent. Then, we saw how these fields, apart from interacting with the storage layer for persisting it, extend Typed Data API classes in order to organize this data better at the code level. For example, we saw that the BaseFieldDefinition instances used on entities are actually data definitions (and so are the FieldConfig ones). Moreover, we also saw the DataType plugins at play there, namely the FieldItemList with their individual items, which down the line extend a basic DataType plugin (Map in most cases).

Overview of this book
Drupal 8 comes with a release cycle that allows for new functionality to be added at a much faster pace. However, this also means code deprecations and changing architecture that you need to stay on top of. This book updates the first edition and includes the new functionality introduced in versions up to, and including 8.7.
The book will first introduce you to the Drupal 8 architecture and its subsystems before diving into creating your first module with basic functionality. You will work with the Drupal logging and mailing systems, learn how to output data using the theme layer and work with menus and links programmatically. Then, you will learn how to work with different kinds of data storages, create custom entities, field types and leverage the Database API for lower level database queries.
You will further see how to introduce JavaScript into your module, work with the various file systems and ensure the code you write works on multilingual sites. Finally, you will learn how to programmatically work with Views, write automated tests for your functionality and also write secure code in general.
By the end, you will 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.
Foreword by Dries Buytaert, founder of Drupal.
