In this tutorial, I will show you how we can build a better blueprint and hierarchical structure for our app’s classes through the use of abstract classes.

In this tutorial, I will show you the power of abstract classes and how you can enforce subclasses to define certain functions. In this way, you can share logic but for things that are really specific to subclasses, you can force them to define certain functions, but with the specific logic required.

In this tutorial, I will show you how to extend an abstract class and ensure that all the methods that are required by the abstract class are included in this new class.

In this tutorial, I will show you how to handle new requirements for data storage by creating two smaller abstract classes out of our original data storage class. By creating these new abstract classes, we can build more flexibility into our code.

Now that we have created new abstract classes, we need to load and utilize them in our code. In this tutorial, I will show you how we can refactor our code to make use of our new abstract data loading classes.
We have an abstract class with methods that we require, but there’s no logic in these abstract methods. This is a perfect opportunity to use interfaces. In this tutorial, I will show you how to create and implement Interfaces. I will also explain how interfaces are useful when you will be sharing your code. But even if you’re not creating interfaces to share, chances are, if you’re using open source code — and definitely in Drupal — you will need to know how to implement interfaces.

CourseComposer
TopicComposer is the preferred dependency management solution for PHP, is used by Drupal core, and is becoming increasingly popular for managing the modules and themes used for a Drupal project.
Drupal Console
TopicDrupal Console provides a command line utility for performing common site administration tasks, code generation scaffolding, and a Read-Evaluate-Print-Loop for interacting with your Drupal site.
Git
TopicThe Git version control system can help you keep track of changes in your codebase and make sure you don't unintentionally lose work.
Security
TopicKeeping a Drupal site secure requires monitoring security announcements, performing regular updates, and knowing how to properly use Drupal’s APIs to write secure code.
Drupal Composer Project
TopicThe Drupal Composer Project provides a scaffold for starting a new Drupal project and managing that project's dependencies with Composer. It was created before the drupal/recommended-project Composer project template was developed, which is the current best practice method for creating a new Drupal site with Composer.
HTML and CSS
TopicHTML and CSS are the foundational languages for how browsers display web pages.
YAML
TopicYAML, which stands for YAML Ain't Markup Language, is a human-readable data serialization format that's been widely adopted in a variety of use cases in Drupal.
Performance and scalability determine how fast your application can serve a page and to how many users at a time.
Xdebug
TopicDebugging your Drupal codebase can be made substantially easier by learning how to enable and configure the Xdebug PHP extension.
Caching in Drupal
TopicCaching in Drupal is controlled by Drupal's Cache API which is used to store any type of data on a permanent or temporary basis. Some types of data tend to take a long time to compute, but utilizing the Cache API in your module can help your site load data more quickly.
