Often you need to create a feature with system variables to make them complete. Features itself does not provide this, but the Strongarm module does, and we'll see how to add that to the mix.

In this video we'll specifically look at using Git as a tool to aid our development process, especially when working with other people, to make sure that you don't step on each others toes and destroy work.

Features are most often used for building out actual site features. Here we look at how you can use Features to provide you with quickstart developer tools as well.

If you have more than one feature module on your site, they can sometimes step on each other and cause nasty conflicts. We'll create some conflicts and show you how this happens and how to back out of them.

When you write your own custom modules, you can make them exportable to Features as well. Here we look at how to do that with the Chaos Tools (CTools) module.

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.

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.
