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.
Formatting standards cover things like the use of whitespace, how to format control structures, and other aspects that affect your code's appearance and format.
In this tutorial we’ll talk specifically about standards regarding formatting. This is by no means an exhaustive list of PHP syntax rules, but rather is focused on formatting standards for Drupal.
By the end of this tutorial you'll know about the most common Drupal code formatting standards as well as where to find more information when questions arise.
Translations have their own special functions in both Drupal 7 and 8, and there are some rules for standardizing how they are used that make things clearer for everyone.
In this tutorial we'll look at:
- When to use, and when not to use, translation utilities to output translatable strings
- How placeholders work in translatable strings
- Tips for creating links inside of translatable strings
By the end of this tutorial you should know when, and how, to make strings in your code translatable using Drupal's translation utility functions.
Once you know what code standards are and why you should use them, you need to learn how to implement Drupal coding standards in your projects. This tutorial will walk through some of the steps you can take to make this as easy as possible. We'll cover:
- Configuring your editor or IDE to warn you of coding standards violations
- Setting up the Coder module and phpcs to scan and review your code
- Performing team code reviews
By the end of this tutorial you should be able to configure your development environment and implement processes in your workflow that help to ensure your code meets Drupal's coding standards guidelines.
Drupal core uses object-oriented programming (OOP). This method of programming introduces new coding standards to the project. In this tutorial we'll cover the Drupal coding standards that relate to object-oriented PHP code.
By the end of this tutorial you should know how to implement the Drupal coding standards related to OOP, and where to find more information when you've got questions about the standards.
Before you dive into using coding standards it makes sense to understand exactly what they are and why they’re important, generally and specifically in the Drupal community. In this tutorial we will look at:
- What coding standards are
- Why following coding standards is a good idea
- Where coding standards come from
By the end of this tutorial you'll have a better understanding of what coding standards are, and why you should be adhering to them when you write code.
Every Composer project is made up of a few standard files and directories. This tutorial provides an overview of the anatomy of a Composer project, and the essential files and directories used by Composer, including:
- What are composer.json and composer.lock files?
- What is in a composer.json file?
- What is the /vendor directory?
By the end of this tutorial you should be able to recognize the standard files and directories in a Composer project and know what they are each used for.
This tutorial demonstrates the value of using Composer. This demonstration will employ the most basic use case of using Composer to create a new, non-Drupal application that writes a message to the system log. It will encompass the fundamental concepts of Composer installation, requiring (installing) a new dependency, autoloading it, and implementing it.
In this tutorial we'll:
- Install Composer
- Use Composer to start a new project
- Use Composer to require a 3rd party dependency
- Use the required code in an example application
By the end of this tutorial you should be able to explain the value of Composer, and have Composer installed and working on your local machine.
This tutorial provides an overview of the concept of an "artifact" and provides step-by-step instructions for deploying a Composer-managed Drupal application to a hosting environment.
In this tutorial we'll:
- Define what an "artifact" is
- Look at how to use Composer and a build process to create and deploy an artifact
- Talk about the benefits of this approach
By the end of this tutorial you should have a general understanding of the steps required in order to deploy a Composer-managed project into production.
You will inevitably encounter Composer issues that require troubleshooting. This tutorial aims to provide some general troubleshooting advice for common Composer issues.
In this tutorial we'll look at:
- Common issues you'll encounter when using Composer
- Solutions to these common issues
By the end of this tutorial you should have some ideas of how to solve common issues that you might encounter when using Composer to manager your application's dependencies.
Composer packages use semantic versioning to allow you to differentiate among different releases of a project. Knowing how this works, and how to specify a version constraint when requiring a Composer package are an important part of using Composer.
In this tutorial we'll:
- Get an overview of semantic versioning
- Look at how Composer version constraints work and related best practices
- Learn how to define Composer package requirements such that you can quickly update all of your application's dependencies without breaking existing functionality
By the end of this tutorial, you should understand how semantic versioning relates to Composer, and how to specify version constraints for packages in your Composer project.
What Is Composer?
FreeComposer is the preferred dependency management solution for PHP. List your project's dependencies in a composer.json file and, after issuing a few commands in the CLI, Composer will automatically download your project's dependencies and set up autoloading for you. Composer is analogous to NPM in the Node.js world, or Bundler in the Ruby world.
Drupal core uses Composer to manage non-Drupal dependencies like Guzzle and PHPUnit. An increasing number of contributed modules also use Composer to integrate third party PHP libraries into Drupal.
This series provides guidance for Drupal developers and site builders who would like to learn to use Composer to build and maintain a Drupal application.
It covers high-level concepts about Composer and walks you step-by-step through creating a new application, downloading PHP libraries, and implementing them using Composer!
It also covers Drupal-specific Composer configuration and provides guidance for accomplishing common Drupal tasks like updating core and installing a new module.
In this tutorial we'll:
- Familiarize ourselves with the general concepts of dependency management
- Learn about Composer and the role it plays in a PHP/Drupal project
- Learn about some advantages and disadvantages of using Composer
By the end of this tutorial you should be able to explain what Composer is, what it's used for, and make the case for using it in your own projects.
