In addition to using one of the existing generators, developers can write their own Drush generator commands. This can help speed up repetitive tasks and reduce the use of boilerplate code that is prone to human error.

Generators are provided through Drush's integration with the Drupal Code Generator project. Writing new generators isn't specific to Drush, though if you're creating generators for Drupal it is definitely easiest with Drush as a wrapper.

Similar to Drush commands, generators can be supplied by a Drupal module or declared globally. If you have a feature-specific functionality, it's best to ship your custom generator within the custom module. Otherwise, a global generator can be declared and used.

In this tutorial we'll:

• Explain the anatomy of a Drush generator
• Write a custom Drush generator for handling a site's development.services.yml file, and use it in a project

By the end of this tutorial you should understand how to create, or customize, a Drush code generator and use it in your project.

There’s no one-size-fits-all path to upgrade from Drupal 9 to Drupal 10, but there is a set of common tasks that everyone will need to complete.

In this tutorial we’ll:

• Explain the differences between Drupal 9 and Drupal 10 that affect the upgrade path.
• Walk through the high-level steps required to upgrade from Drupal 9 to Drupal 10.
• Provide resources to help you create an upgrade checklist and start checking items off the list.

By the end of this tutorial you should be able to explain the major differences between Drupal 9 and 10, audit your existing Drupal 9 projects for Drupal 10 readiness, estimate the level of effort involved, and start the process of upgrading.

Code generators are great productivity boosters that allow generating scaffolds for common development tasks in Drupal. One of the most common use cases for generators is scaffolding the code required for a custom entity type. Custom entities require many files and complicated annotations in order to function properly. There is a lot of boilerplate code that is more-or-less the same for every entity type. Creating all the files is repetitive, time-consuming, and prone to human error. Generators can help automate this task and make creating your own custom entity types quicker.

In this tutorial we'll:

• Learn how to generate the code for a custom entity with Drush
• Learn about the options that generators provide for custom entities

By the end of this tutorial you should know how to generate custom entities with Drush.

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.

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.
