Back in March, 2022, the DDEV team announced support for Colima, an open-source Docker Desktop replacement for Mac OS X. Based on the fact that Colima is open-source, Docker Desktop's new license terms, and the apparent performance gains of using Colima it seems like a no-brainer to give it a spin. First off, it's almost a drop-in replacement for Docker Desktop. I say almost for one reason, as any existing DDEV projects will need to have their databases reimported. In other words, if you have an existing project up-and-running in DDEV, then add Colima, then restart the project, your database

Update (November, 2025): parts of this blog post are likely obsolete due to recent changes to DDEV. See https://github.com/ddev/ddev/releases/tag/v1.24.8 Reposted with permission from Pantheon.io. ## Automating the Process of Keeping Your Local Environment Up-to-date DDEV is a Docker-based local development environment solution that allows developers to run local copies of all their Drupal and WordPress projects in a personal development environment. Much like similar Docker-based solutions, DDEV hides most of the complexity of Docker — allowing Drupal and WordPress developers to focus on what they like best. ## What Problem Are We Solving? One of the typical challenges that a

Having a basic understanding of caching is a requirement of being a professional Drupal developer. Unfortunately, there can be many layers of caching which can make it challenging to figure out exactly how best to configure cache settings and troubleshoot potential caching issues. Web page caching can be thought of as moats around the castle, where each moat is a caching layer and the castle can be thought of as the site's web, database, and other origin servers. HTTP headers provide a mechanism for the client (usually a web browser) and a server (usually a web server) to exchange information

If you're a Drupal developer who designs information architecture (IA) for your organization and/or clients, then hopefully by now you're thinking in terms of entities, bundles, and fields, not limiting your thinking to only content types. This article isn't going to dive into a lesson explaining what entities, bundles, and fields are as there is plenty of great documentation about that. Back in the Drupal 7 and earlier days, it was common to look at an organization's data and map it almost exclusively to only content types (maybe a few vocabularies as well). With Drupal 8's and 9's Entity API

Over the past few years, the Drupal community has been (sometimes slowly) embracing the Composer dependency manager tool for PHP projects. We have become accustomed to adding Drupal modules and base themes to our projects using composer require but many of us have only scratched the surface of what more Composer can do for us. In this article, we'll go step-by-step in adding a non-PHP dependency to our project using Composer - as well as the helpful Composer installers extender plugin. We'll utilize Asset Packagist, a Composer repository for many popular NPM and Bower assets including things like Javascript libraries

One of the primary goals of the upcoming Composer 2.0 release is decreasing the memory footprint and increasing the performance of common commands. I decided to test out the performance of the second alpha release of Composer 2.0 to see how much real-world change users can expect to see. tl;dr: Composer 2.0 will be much faster and use much less memory. Users can expect to see up to a 2x gain in speed in composer create-project commands, up to a 10x gain in composer require commands, and a over a 2x gain in composer update commands. On the memory side

This blog post was updated October, 2022 with new information about accessCheck, an example for loading fully populate node objects from entityQuery results, and the loadByProperties() method. The Drupal::entityQuery method has been a staple for Drupal developers since the early days of Drupal 8. But without a dedicated drupal.org Documentation page, it can be difficult for new developers to get a really good handle on. I've been using the QueryInterface API documentation for a few years now as my go-to source for help with using entityQuery, but a couple of weeks ago I stumbled on a feature of entityQuery that

Waaaaay back in 2013, I wrote a blog post about importing and mapping over 5,000 points of interest in 45 minutes using (mainly) the Feeds and Geofield modules. Before that, I had also done Drupal 6 demos of importing and displaying earthquake data. With the recent release of Drupal 9, I figured it was time for a modern take on the idea - this time using the Drupal migration system as well as (still!) Geofield. This time, for the source data, I found a .csv file of 814 lighthouses in the United States that I downloaded from POI Factory (which

As always-evolving Drupal developers, we have been in the process of moving towards having a Composer-based workflow for managing our Drupal project codebases. While it is (normally) an easy jump from "drush dl" to "composer require" for Drupal contrib modules and themes, there's another significant opportunity for us to take advantage of during this evolution that should be considered. We are all familiar with the concept that Drupal modules extend the functionality of Drupal site; we should also be embracing the fact that there is a whole class of Composer dependencies that extend Composer's functionality. These are appropriately called "Composer

If you use Drupal 8's configuration system, then you know that one of the trickiest parts of using it effectively is managing configuration on a per-environment basis. Luckily, the Config Split module makes it easy to manage different configurations in different environments, but how to set it up properly isn't always readily apparent. In this blog post, I'll provide one method for setting up Config Split in an efficient manner, with splits for local, remote development, and production environments. The goal is to be able to set things up right the first time, without having to worry about manually enabling/disabling

If you build Drupal 8 sites using the Drupal Composer/Drupal Project Composer template (DCDP), then you've likely noticed the development dependency webflo/drupal-core-require-dev. If you're like me, you probably didn't give it much thought the first 20 or 30 times you used the template. After a while though, I started to dig deeper into the details of DCDP, wanting to be able to understand exactly how it worked and what customizations I may want to make. DCDP was really my first real exposure to Composer, and the more I learned, the more I wanted to learn (as is often the case)

Version 1.9.0 of DDEV-local introduced the ability to share your local project online via a temporary, public URL using ngrok. This allows you the ability to quickly and securely provide access to your local site to other developers and stakeholders as well as an easy way to test your local site on other devices. ngrok is a service that exposes local servers behind NATs and firewalls via public URLs over secure tunnels. Once the small ngrok client is installed on your local machine, the ddev share command will enable the sharing and provide you with a public URL for your

Local development environments are in the midst a bit of a renaissance recently - mainly driven by the maturation and adoption of Docker-based solutions. I've been using (and recommending) DDEV for awhile now, and one of the things that I really like about it is the consistent pace of development. Since early February, there have been three minor releases of DDEV (1.6, 1.7, and 1.8). With each minor release of DDEV comes new, often very useful features. Here's just a few of my recent favorites: NFS Mounting One of the few disadvantages of using a Docker-based solution over a native

As someone who has been building Drupal sites for over 12 years now, I'd like to think that my knowledge and expertise has grown at a rate similar to the power, flexibility, and complexity of the Drupal project itself. For well over 10 years, Drupal training and development has been the focus of my consulting business; over the holidays I took some time to look back and really think about the lessons I've learned and how I can utilize them moving forward. In addition to documenting the process for myself as well as my current and future clients, I also

Over the past year or so, I've been looking to replace my standard local development environment with a Docker-based solution. I've been evaluating DDEV, Docksal, and Lando (listed alphabetically), trying to figure out not only was the best for me, but also the best for me to teach and recommend to the hundreds of folks I teach both long-form and full-day Drupal workshops to each year. As I've test-driven each of these three options, I've been periodically posting tutorials on various related topics. As a long-time Mac OS X user, my previous go-to local development stack has been a mix
