Managing a Drupal application with Composer requires a few modifications to Composer's default behavior. For instance, Drupal expects that specialized packages called "modules" be downloaded to modules/contrib rather than Composer's default vendor directory.

Additionally, it is common practice in the Drupal community to modify contributed projects with patches from Drupal.org. How do we incorporate Drupal-specific practices like these into a Composer workflow?

In this tutorial we will:

• Address all of the Drupal-specific configuration necessary to manage a Drupal application using Composer

By the end of this tutorial you should know how to configure Composer to work with Drupal, and drupal.org.

When managing your Drupal project with Composer you'll use Composer commands to download (require) modules and themes that you want to install, as well as issuing commands to keep those modules and themes up-to-date when new versions are released.

In this tutorial we'll:

• Cover step-by-step instructions for performing common Composer tasks for a Drupal application
• Install and update Drupal projects (core, modules, themes, profiles, etc.) using Composer
• Convert an existing application to use Composer

By the end of this tutorial you should know how to use Composer to install, and update, Drupal modules and themes.

Docker often seems like an impenetrable product. Is it a VM system? A suite of development tools? A clustering product? A software distribution facility? When the answer is "yes" to each of these, it only becomes more confusing. For the Drupal developer, Docker is a way to provide a local development environment to run web server software.

In this tutorial, we'll:

• Define the terms hypervisor, virtual machine (VM), and containers
• List the advantages of containers over VMs
• List the advantages of Docker for Drupal developers

Often, there's an existing Drush command that does most of what you want, but needs just a few tweaks or enhancements to make it meet your project requirements. Maybe the existing core Drush command has the functionality but lacks some additional validation. Or maybe you need to add an option to perform some application-specific debugging logic for all commands in a group.

Drush hooks can be used to alter, extend, and enhance existing Drush commands.

In this tutorial we'll:

• Learn how to alter a Drush command with code in a custom module
• Declare a validation hook that alters the user:password command with additional password validation logic

By the end of this tutorial you should be able to alter a Drush command provided by Drush core or a contributed module with your own custom code.

Back-end developers, and Drupal site builders, often find themselves having to perform the same UI steps over and over again, like exporting configuration, importing configuration changes, running cron, processing a large queue of jobs, indexing items for Search API, and more. Performing these tasks with Drush saves time and reduces the number of clicks required.

Drush core contains commands to execute all the most common tasks. Many contributed modules provide their own Drush commands to make interaction with the module's features, easier, faster, and scriptable.

In this tutorial we'll:

• Learn about the Drush core commands for common tasks like interacting with queues, performing database backups, and importing/exporting configuration
• Demonstrate how to find the Drush commands provided by contributed modules in your project

By the end of this tutorial you'll learn some popular commands for common tasks that'll speed up your daily work.

Every Drupal site consists of many Drupal projects like modules and themes. Drush comes with a group of commands that aid in managing projects from the command line. These commands can check which modules are present in a site's codebase, report their security status, enable modules, and display metadata for modules and themes. All of these commands start with the pm prefix, and are part of the project manager group.

Common use cases for the project manager commands include: quickly enabling/disabling modules via the CLI rather than performing numerous clicks in the UI, and as part of CI/CD process that lists (or maybe even automates) security updates.

In this tutorial we'll:

• List the available pm commands
• Enable a module with Drush
• Uninstall a module with Drush
• Use Drush to check for security updates for modules, themes and PHP packages

By the end of this tutorial you'll have an understanding of the project manager commands that come with Drush, how to use them, and how to speed up common workflows and maintenance tasks.

Administration and maintenance of Drupal websites consists of many tasks that can both be performed via the command line, and automated, with Drush. Using Drush's site and environment administration commands you can run database updates, check an environment's status, clear (rebuild) the cache, perform Cron-related operations, and manage users. These tasks are repetitive, often require many steps in the UI, and may be tedious in the long run. Learning to execute them with Drush can save you time and allows for more automation of common tasks.

In this tutorial we'll:

• Use Drush to check a site's status
• Learn how to perform database updates with Drush
• Clear the Drupal cache with Drush
• Use Drush to execute Cron tasks for a Drupal site
• Learn how to use Drush to login to a site as any user, and manage existing users

By the end of this tutorial you'll be able to perform many common Drupal environment and administration tasks from the command line with Drush. We're not going to cover all of the environment management commands in this tutorial, just some of the more popular ones. We encourage you to explore further on your own.

Drush, aka The Drupal Shell, is a command line utility and UNIX scripting interface for Drupal. It allows access to common Drupal features and tasks via the command line. It can help speed up common tasks for Drupal site builders, developers, and DevOps teams. Among other things, it makes it easier to integrate Drupal into CI/CD workflows.

In this tutorial we'll:

• Learn what Drush is and what can be done with Drush
• Install Drush
• Find a list of Drush commands
• Learn how to execute commands

By the end of this tutorial, you'll understand how to install and use Drush with your Drupal projects, navigate the list of its commands and run them. This is intended as an overview. Other tutorials will provide more detail about common commands and use-cases.
