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

Gain a clear understanding of the most important concepts in the decoupled CMS landscape. You will learn how to architect and implement decoupled Drupal architectures across the stack—from building the back end and designing APIs to integrating with front-end technologies. You'll also review presenting data through consumer applications in widely adopted technologies such as Angular, Ember, React, and Vue.js.

Featuring a foreword by Drupal founder and project lead Dries Buytaert, the first part of this book chronicles the history of the CMS and the server–client divide, analyzes the risks and rewards of decoupled CMS architectures, and presents architectural patterns. From there, the book explores the core and contributed landscape for decoupled Drupal, authentication mechanisms, and the surrounding tooling ecosystem before delving into consumer implementations in a variety of technologies. Finally, a series of chapters on advanced topics feature the Drupal REST plugin system, schemas and generated documentation, and caching.

Several projects point to a decoupled future for Drupal, including the Contenta CMS and work to modernize Drupal's JavaScript using React. Begin learning about these and other exciting developments with Decoupled Drupal today.

What You’ll Learn

• Evaluate the risks and rewards of decoupled Drupal and classify its architectures
• Authenticate requests to Drupal using OAuth, JWT, and Basic Authentication
• Consume and manipulate Drupal content via API through HTTP requests
• Integrate with other consumer applications for native mobile and desktop as well as set-top boxes (Roku, Apple TV, Samsung TV)
• Add new resources to Drupal's REST API using the REST plugin system
• Generate API documentation that complies with the OpenAPI (Swagger) standard

Learn

• Create and customize Drupal structures, such as menus, tags, and content categories
• Extend Drupal's capabilities with add-on modules
• Administer site users, their roles, and the actions to which they are granted access
• Understand user roles and permissions
• Create, edit, and publish content
• Use Views for custom content selection and display
• Expand your audience with custom RSS feeds
• Configure a home page with meaningful sections for a better UX

About

Drupal is a powerful content management platform, ?exible enough to accommodate almost any content requirements. This ?exibility comes with a cost: complexity. Drupal 8 Quick Start Guide will clear your path from installation to a building usable site in minutes, and to a customized site in one sitting.

You will begin with installation of Drupal and going through the main sections of the Drupal UI. Then, you will create a content type that describes its content, which simplifies the act of creating and editing the actual content later. You will learn about user roles, using real-world examples. This will help you to learn how to design roles, and how to assign appropriate permissions to them. Next, you will learn to use the WYSIWYG editor, configure it for other roles, navigate the various fields on the content creation form, and publish content.

To begin to appreciate the ?exibility and expandability of Drupal, you will make use of popular content-focused modules that extend Drupal's power. You will learn how to expand your market to other readers directly and through other sites by configuring content and UI translations and creating a View that provides an RSS feed. Finally, you will put everything together by customizing the home page for your new website.

Features

Build a great Drupal website easily
How to structure, create and maintain different types of content
Design roles for secure editing of your site

Implement a headless/decoupled Drupal design to build easily maintainable web applications. This book begins by showing you CMS workflows and best practices to give you the basics you need for working with decoupled Drupal. As part of this process, Decoupling Drupal reveals the advantages of using content management systems and explains that decoupled Drupal is the answer to various problems faced in creating and maintaining enterprise applications.
Decoupling Drupal will show you how administering Drupal monolithically to design web applications can be a challenge. You’ll see how the maintainability of your application reduces exponentially over the years. In contrast, a decoupled design enables an easy handshake between the front-end and back-end applications, meaning you can implement services in a short amount of time and scale them quickly.
The final part of the book covers the impact of decoupling on functional and non-functional requirements and the use of Drupal 8 modules to address the requirements of decoupling. This involves solving the problems that occur at different stages of CMS evolution in an organization.

What You Will Learn

• Discover the principles of headless/decoupled design
• Implement Drupal in a real-time environment
• Work with the Drupal modules normally used in a decoupled design
• Use Drupal to complete back-end tasks
• Integrate a Pantheon cloud-solution for headless Drupal
• Acknowledge the use of CMS in your day-to-day IT life
