Updating WordPress with Composer and WP-CLI

The other day I came across this blog post by Mark Jaquith, who is one of the lead contributors to WordPress, in which he describes his process of updating WordPress plugins with WP-CLI and Git.  I think a lot of people these days are trying to use Git for version control and automate their deployments, so WordPress developers aren’t an exception, and Mark’s post is a useful resource for that.

With that said, however, I think there is a better.  At work, we’ve been dealing with quite a few WordPress-based projects, and automation of builds and deploys is very important to us.  So we’ve taken a different approach.

The initial inspiration for our approach was taken from this blog post by Scott Walkinshaw of the amazing Roots team.

Yes, that’s right, we use Composer to manage the WordPress, plugins and themes, both during the initial installation and the upgrades later.  But we’ve taken it a step further by also integrating the WP-CLI to our setup, which you can find in our project-template-wordpress GitHub repository.

I have oversimplified both the development and deployment process below, mostly for clarity.   (We do a lot more automation for our needs.)

During the development:

  1. Configure Composer to install WordPress into the webroot/wp folder.
  2. Configure Composer to install plugins and themes into webroot/wp-content folder. (Notice: we use a different wp-content folder location from the default WordPress one).
  3. Adjust wp-config.php for the new paths and drop it into the webroot/ folder.
  4. Add Composer’s vendor/ folder, and both webroot/wp and webroot/wp-content to .gitignore.
  5. Add all required themes and plugins to the composer.json.
  6. Run composer update to create or update the composer.lock file.
  7. Commit both composer.json and composer.lock, as well as .gitignore and any other files you modified.
  8. Add a WP-CLI script that automates activation of plugins and sets the current theme.
  9. Push your changes to the git repository.

During the deployment:

  1. Clone or pull the changes from the git repository.
  2. Run composer install to fetch and install specific versions of WordPress, plugins, and themes, from the composer.lock file.
  3. Run the WP-CLI script to finalize the installation or update with the plugin activation, theme selection, etc.

While it might look a little bit more complicated than what Mark and Scott described in their respective blog posts, I think this is a better approach for the following reasons:

  1. Use a specialized tool to solve each problem.   Git is great for version control, so that’s what it should do.  Composer is great for managing dependencies, and that’s what WordPress and its themes and plugins are for your project.  WP-CLI is great for automating WordPress tasks.
  2. Keep the git repository clean and simple.  When working on a project, we never ever modify the code of the WordPress or any of its themes or plugins.  And our setup enforces this approach.  If you need to change the WordPress source code for a particular project, you are probably doing something wrong.  If you need to change the plugin’s source code or the theme’s source code, you are probably doing something wrong again.  Instead create child theme or your own version of the plugin and install those with Composer, keeping the plugin or theme related code changes in a separate repository.
  3. Easily extendable and customizeable.  Git, composer, and WP-CLI are great tools and we love using them.  But the world is moving forward and there are constantly more and better tools to help with the complexities of the web development.  Our setup expands and extends to welcome any tools that we find useful.  For example, we have integrated with Robo, PHPUnit and PHP Code Sniffer, TravisCI, BitBucket Pipelines, and many other tools over time.  We’ve also said good bye to a few that became obsolete or to which we found better alternatives.

Anyways, project-template-wordpress works quite well for us and I hope you’ll find it useful.  Give it a try and let us know if you find any issues or improvements.   Pull Requests are welcome. :)

WordPress is absolutely a tool that can (and given the state of the tools they were previously using, should) be used by Ye Olde Media Guarde. We’ve even made some steps toward supporting a basic editorial workflow with the Contributor role (which can submit posts for review, but not publish them). But using WordPress in that way is like using a computer to print a letter and then fax it to your recipient. It feels like an artificial restriction. We’ve empowered individuals to publish what they want to publish, when they want to publish. Reinstating the print media workflows of the last century very much feels like a step backwards. Writers got a taste of true publishing freedom. Readers got a taste of what it’s like to actually have a connection and conversation with a writer instead of just being delivered their words. We can’t pretend that didn’t happen.
