Description

Drupal is an open source web-based content management system (CMS) that can be used for building anything from simple websites to complex applications. It enables individuals and organizations to build platforms that engage users and deliver the right content at the right time. Drupal 8 is an exciting new development in the Drupal community. However, the differences from the previous version are substantial and this can put quite some pressure on Drupal 7 developers that need to catch up. This book aims to help such developers in getting up to speed with Drupal 8 module development. The book first introduces you to the Drupal 8 architecture and its subsystems before diving into creating your first module with basic functionality. Building upon that, you will cover many core APIs and functionalities available to module developers. 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. Moreover, you will learn about the Drupal 8 access system and caching layer as well as the APIs used for data processing (queues and batches). 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 of the book, you will have learned how to develop your own custom module from scratch that can help solve a small problem or even provide complex functionality. And who knows, maybe you’ll even contribute it back to the Drupal community.

Who is this book for?

The primary target of this book is Drupal developers who want to learn how to write modules and carry out development in Drupal 8. It is also intended for Drupal site builders and PHP developers who have basic Object Oriented Programming skills. A little bit of Symfony experience is helpful but not mandatory.

Great book if you want to learn Drupal8.

James Danforth Feb 15, 2018

Excellent is an understatement. This book is allowing me to get up to speed on Drupal 8 development at least 10X faster than if I had to sort through all the Drupal 8 documentation on my own. The book is my train into a big Drupal territory. If you need to develop in version 8 and you need to get fast track information on how to do it well, fast, this is the book for you. The book vastly flattens out the early part of Drupal 8's learning curve for those without a lot of experience with it. I would buy it again for sure.

Very good book for Drupal developers.

M.G. Aug 14, 2019

Throughly conceived, and brilliantly executed. A really good resource for an in-depth look at Drupal 8's many aspects. Use it for reference all the time.

William A. Kudrle Jun 09, 2018

I am surprised that this has not gotten more reviews. I have not found another book that is as thorough and in-depth about how Drupal 8 works. It goes over custom module development, as the title implies, but it also goes into depth about how the internals of Drupal 8 work as well. Many improvements have been made to the internals of Drupal 8, but it is difficult to know many of them unless you have a text like this to guide you. I liken this book to what Pro Drupal Development by John Van Dyke was for Drupal 6. Reading through Van Dyke's book was what gave me the ability to actually create custom Drupal 6 modules. This book is doing that for me for Drupal 8. The only criticism that I would have is that it would be nice to have more details about how to use the Drupal console to create custom modules and plugins. That may be too much of a moving target, but in practical terms just getting the basic modules and plugins to be generated with Drupal console can be a confidence boost and provide some understanding from the immediate feedback of the basic custom code.I highly recommend this book if you really want to understand what is going in with Drupal 8 and/or intend to do any custom programming.
