Front-End development in Drupal 9 encompasses all interface-related technologies that run in the web browser. We can group these technologies into three languages, HTML, CSS and JavaScript. Although these technologies are used as a base, we will see that there are other more advanced solutions that facilitate Front-End programming. For example, we will use SASS for CSS generation and JavaScript libraries such as jQuery or VueJS.

Back-End development in Drupal 9 refers to the programming of modules and components that allow extending the functionality of the system. It is mainly object-oriented PHP programming, although we will also see other technologies needed during the development of a web project.

Site Building is all that can be done through the user interface without programing. Drupal has a large number of contributed modules that allow us to extend Drupal’s functionality and build complex websites. We will look at what functionality is included in Drupal core and how that is extended through contributed modules.

About

Drupal is an open source content management system that empowers millions of independent developers and organizations with end-to-end website solutions. Updated to include the new functionalities introduced in Drupal 9, this third edition of the Drupal Module Development guide will help you to stay on top of code deprecation and the changing architecture of Drupal with each new 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. This Drupal guide will take you through different kinds of data storage before helping you 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, 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!

Features

• Explore a plethora of Drupal 9 APIs and get the best out of them using PHP programming
• Create modules for efficient data management, security, and much more in your Drupal sites
• Discover best practices for transitioning from legacy Drupal 7 and Drupal 8 APIs to Drupal 9

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.

Still not sure if you need this book? If at least 3 of these are true, this book is for you:

1. You’ve got a Drupal 8 website. Either you took it over, your company built it, or you’re about to launch a new endeavor and Drupal 8 is the right technology you need to get the job done.
2. You need a Drupal 8 SEO shortcut. This book is the shortcut to getting your Drupal 8 website optimized, ranking, and working for your business.
3. You already use the Drupal 8 SEO Checklist module. I created this book to be a supplement to the SEO Checklist module for Drupal 8. If you’re already using the module, this book is for you.
4. You’ve invested a lot in Drupal 8 already. All the hard work your team has done to create a great website will go to waste if you don’t generate a steady flow of customers ready to buy, sign up, or join.
5. You’re not looking for an SEO education. This book is short on SEO “whys” and long on Drupal 8 “how-tos”. Instead of rehashing common SEO concepts, I’ve linked to trusted online resources that explain the basics.
6. You’ve SEO’d another platform and need to SEO Drupal. Drupal does SEO differently. This book will empower you to be more productive and successful using Drupal best practices (also known as The Drupal Way).
7. You can implement a solid SEO strategy yourself. This book will help you implement that strategy.
8. You need to rank in the search engines. Ranking well in Google matters. A lot. It’s not an afterthought - or at least it shouldn’t be - it’s at the forefront of your mind as a marketer.
9. Winning matters to you. Companies that rank well in Google win. Companies that don’t rank are not even in the running - it’s just that simple.
10. You’re a visual person. They say a picture is worth a thousand words so there are over 150 Drupal 8 screenshots in this book. My goal is for you to see exactly what to do, where to click, and how things work.

If you’re ready for results with the minimum of hassle, Drupal 8 SEO will lead the way to a successful SEO marketing campaign on your website.
