Drupal 10 Module Development

This is the code repository for the book Drupal 10 Module Development published by Packt.

Get up and running with building powerful Drupal modules and applications

Instructions and Navigations

All of the code is organized into folders. For example, Chapter02.

The code will look like the following:

hello_world.hello:
  path: '/hello'
  defaults:
    _controller:  Drupal\hello_world\Controller\HelloWorldController::helloWorld
    _title: 'Our first route'
  requirements:
    _permission: 'access content'

Following is what you need for this book: If you are a Drupal developer looking to learn Drupal 10 to write modules for your sites, this book is for you. Drupal site builders and PHP developers with basic object-oriented programming skills will also find this book helpful. Although not necessary, some Symfony experience will help with understanding concepts easily.

With the following software and hardware list you can run all code files present in the book (Chapter 1-18).

Setup

To set up a local development environment, perform the following:

1. Run the following commands:

$ docker-compose up -d
$ docker-compose exec php composer install
$ docker-compose exec php ./vendor/bin/run drupal:site-install

2. Go to http://localhost:8080 and you have a Drupal site running. To log in, use admin / admin.

Modules

The modules covered in the book are found inside the packt folder in the root of the project. These are duplicated in each chapter and are individually symlinked in the Drupal custom module folder.

By default, when setting up the project, the chapter 2 modules are symlinked. You can change this by creating a local runner.yml file and overriding the chapter value that is used in the symlink (check the default in the runner.yml.dist file).

Once that is done, you can run the following command to symlink the right modules:

$ docker-compose exec php ./vendor/bin/run drupal:module-setup

Mails

All outgoing sent using the native PHP mailer are caught using Mailhog. You can access the emails at http://localhost:8025.

Tests

Run tests as follows:

$ docker-compose exec -u www-data php ./vendor/bin/phpunit

This will run all the tests in the configured packt modules.

Coding standards

To run the coding standards check, use this command:

$ docker-compose exec php ./vendor/bin/run drupal:phpcs

And this command to try to automatically fix coding standards issues that pop up:

$ docker-compose exec php ./vendor/bin/run drupal:phpcbf
