A development environment is any copy of your site that operates separately from the live site. Development environments allow you to make changes, try new modules, write new code, and test new ideas, on a copy of your site instead of the real thing, ensuring those changes happen in a sandbox where you're not affecting anyone trying to use the live version of your application.

This is typically done by installing the server software required to run Drupal on your own computer and then creating a clone of your existing database and files. Or you might have a separate instance of the site setup on the existing infrastructure.

Here's a basic recipe for setting up a new development environment:

  1. Install web server, database server, PHP, and Git
  2. Either install Drupal if starting from scratch, or clone the code, database, and user-generated files from your live site
  3. Clear the cache

Example tasks

  • Install Drupal on, or copy an existing site to, your computer to do development
  • Test modules and code without affecting the production site
  • Test server configuration changes on your localhost before deploying them to production

Confidence

There are dozens of ways to do this, and none is the only right way. The bare minimum requirement is that you have PHP, a web server, and a database running on the computer where you would like to install Drupal. Beyond that, it's mostly personal preference.

First, learn about best practices in Drupal Development.

Best Practice Drupal Development

Free
Module Development, Drupal 8, Drupal 7
More information

Today's Drupal developer needs more than just a text editor and FTP. Best practice Drupal development involves a suite of tools, processes, and more than one server environment.

This tutorial is directed toward an audience that is not familiar with best practices in Drupal Development and methods involving version control with Git, IDEs, local development environments, and deployment environments (i.e. stage, live). Here we're providing a high-level overview of these topics with links to dive deeper if you need more information.

In this tutorial, we'll cover:

What is a development site? These tutorials from the Drupal 8 User Guide will help you understand what you need in a local development environment, in order to run Drupal locally on your machine.

For the Drupal developer, Docker is a way to provide a local development environment to run web server software.

Learn about why it's important to clone an existing site with Drupal 8. Then do it, either via the Command Line Interface (CLI), or with Graphical User Interface (GUI) tools.

Create a Clone of Your Drupal Site

Site Administration, Drupal 8, Drupal 9
More information

Before you can get started synchronizing configuration between instances of your site, you'll need to create a new instance or "clone" of your Drupal site.

By the end of this tutorial, you should know:

Clone a Drupal Site with GUI Tools

Site Administration, Drupal 8, Drupal 9
More information

The configuration system in Drupal was designed to manage and sync configuration between instances of a Drupal site. So before configuration management can be useful, we must have another instance--or clone--of our Drupal site. In this lesson, you will learn:

Learn how to use Git to keep the code on your development environment in sync with that on the live site.

Git

The Git version control system can help you keep track of changes in your codebase and make sure you don't unintentionally lose work.

Now that you've got a copy of your Drupal site on your local environment, using an IDE (Integrated Development Environment) such as PhpStorm can be highly useful, as it can autocomplete various language constructs, help you quickly locate inherited classes, alert you when a function is deprecated, provide debugging tools, and much more.

Making Drupal fast by default implies having caching layers and CSS and JavaScript aggregation utilities enabled out-of-the-box. As a theme developer this can be annoying, because you must clear these various caches in order to preview any changes. In addition, inspecting variables with debugging tools often produces PHP errors. We'll make some recommendations for PHP settings on your local environment that can prevent these errors from happening so often.
