Development environments provide a sandbox where you can work on your application without affecting the live site.
Back up Your Drupal Site
TopicA reliable backup will allow you to restore your site if something goes wrong.
Composer for Drupal Users
CourseJavaScript in Drupal
TopicJavaScript files are included by a module or a theme by creating an asset library. Using this asset library system you can selectively choose which files to load, overwrite existing files, or customize them to suit your needs.
Drush
TopicDrush is a command line interface that enables you to interact with your Drupal site without clicking around the graphical user interface (GUI).
PhpStorm
TopicThe PhpStorm integrated development environment (IDE) contains dozens of useful features that make working with a Drupal codebase easier.
Hooks
TopicHooks allow modules to alter and extend the behavior of Drupal core, or another module. As a Drupal developer, understanding how to implement and invoke hooks is essential.
Blocks
TopicA block is a reusable widget that is placed inside regions (layout containers) of your theme. Blocks can be used by site administrators on the Block layout admin page or provided by a module using the Plugin API.
In this exercise you will demonstrate that you understand the CSS patterns used for smaller elements of Drupal such as fields, and can create selectors which override them appropriately. You will also override template files to create your own markup and suggest new template files.
In this exercise you will demonstrate your ability to attach JavaScript to themes, and use Drupal behaviors to enhance the functionality of a website.
In this exercise you will demonstrate that you understand the concept of responsive CSS and the methods which can be used to implement it in a Drupal theme.
Configure basic settings which affect performance, and perform basic analysis to understand what might be affecting website performance.
Every Drupal module needs a *.info.yml file; the basic structure of a form controller class and related routing is the same for every form; and much of the code required to create a custom content entity type is boilerplate annotations and extending base classes. Wouldn't it be nice if there was a way to automate some of that repetitive work? Drush can be used to speed up module development by generating scaffolding code for event subscribers, forms, services, module files, routing, and much more. These generators are provided by the Drupal Code Generator project. They're neatly bundled up in Drush under the drush generate
command.
Before Drush 9, there were no code generators in Drush, but the Drupal Console project provided them. That project and its code generators, have languished since the release of Drupal 9. While it can still be used, and is often referenced in tutorials about Drupal, we much prefer the code generated by Drush at this point.
In this tutorial we'll:
- Learn about the Drupal Code Generator project
- Learn how Drush integrates with this project
- Demonstrate the
drush generate
command and its options
By the end of this tutorial, you'll know how to use the drush generate
command to speed up development for your Drupal modules.
A multisite Drupal installation allows you to host multiple, separate websites while relying on the same set of code. Large organizations often rely on a multisite installation to cut down on the operational upkeep of multiple sites. Hosting a multisite in Docker poses several additional challenges. Fortunately, the process is not dissimilar from configuring a bare-metal server to run a multisite.
In this tutorial, we'll:
- Outline a multisite's additional requirements for Docker containers.
- Configure alternate, local domain names to resolve each site.
- Learn how to configure a multisite to use alternate domain names.
In this exercise you will demonstrate your ability to create a custom theme as a subtheme based on Zen and use Sass.
This exercise will have you demonstrate an understanding of Drupal themes and how to develop CSS to theme the default markup created by Drupal, with particular reference to CSS naming conventions.
Drush is the command line shell and Unix scripting interface for Drupal. The most common way to install Drush is to install it on a per-project basis using Composer. We'll walk through the steps to do that, as well as how to set up the Drush Launcher tool (to make it possible to execute Drush commands without having to specify a full path to the executable).
In this tutorial we'll:
- Install Drush
- Verify it worked
By the end of this tutorial you'll have Drush installed.
Installing Drupal using the instructions in this tutorial will give you a working Drupal site that can be used for learning, or real-world project development.
Before you can work on a Drupal site locally (on your computer), you'll need to set up a local development environment. This includes all the system requirements like PHP and a web server, that Drupal needs in order to run. Our favorite way to accomplish this is using DDEV.
In this tutorial we'll learn:
- How to install and configure DDEV for use with a Drupal project.
- How to use DDEV's integrated Composer to download Drupal and Drush.
- How to install Drupal inside DDEV so you can access the site and start doing development.
By the end of this tutorial, you should be able to set up a local development environment for learning Drupal or working on a new Drupal project.
Standardized documentation is crucial to a project, whether it is just you or an entire team working on it. In this tutorial we're going to look at:
- Standards for
@docblock
comments - Standards for inline comments
- Why standards for documentation and comments are as important as standards for the rest of your code.
By the end of this tutorial you'll know how to add inline documentation for all the PHP code that you write for Drupal.
