Version control is non-negotiable for professional WordPress plugin development. Whether you’re working solo or with a team, Git gives you the ability to track changes, experiment with new features without risk, and roll back mistakes with confidence. GitHub adds collaboration, code review, and automation on top of Git’s foundation.
This guide covers a Git workflow optimized for WordPress plugin development, from repository setup to release automation.
Repository Structure for Plugins
A well-organized plugin repository follows a standard structure. The main branch — typically main or master — always reflects the current stable release. The develop branch is where work in progress lives. Feature branches branch off develop and are merged back via pull requests.
Your repository should include your entire plugin directory, minus third-party dependencies that are managed by Composer or npm. Add a .gitignore file that excludes vendor, node_modules, .log files, and operating system files like .DS_Store.
Branch Strategy: Git Flow Simplified
A simplified Git Flow works well for most plugin teams. Maintain a main branch for releases, a develop branch for integration, and short-lived feature branches for individual changes. When starting a new feature, branch from develop with a descriptive name like ‘feature/add-pdf-export’. When the feature is complete, open a pull request to merge it back into develop.
For bug fixes, use a ‘fix/’ prefix instead of ‘feature/’. This makes it easy to distinguish between new functionality and corrections when reviewing branch history.
Commit Messages That Tell a Story
Good commit messages explain why a change was made, not just what changed. The conventional commits format works well for plugins: ‘feat: add PDF export functionality’, ‘fix: correct timezone handling in booking calendar’, ‘docs: update installation instructions’.
Write the commit subject in the imperative mood — ‘Add feature’ not ‘Added feature’ or ‘Adding feature’. Keep the subject under 50 characters. Add a blank line and a detailed body if the change needs explanation. Reference issues and pull requests with their numbers.
Code Review Best Practices
Pull requests are the standard mechanism for code review on GitHub. Open a PR when your feature is complete and tested. Include a description of what the change does, how to test it, and any relevant screenshots or screencasts.
Reviewers should check for security issues, coding standards compliance, backward compatibility, and test coverage. Keep PRs small and focused — a 50-line PR is easy to review thoroughly. A 500-line PR is likely to have issues that slip through.
Automated Testing and CI
GitHub Actions can run your tests automatically on every push and pull request. Set up a workflow that runs PHPUnit tests, checks PHPCS coding standards, and validates your plugin against the WordPress Coding Standards. Add a status badge to your README so users can see your test status at a glance.
For plugins targeting the WordPress.org directory, add a deployment workflow that automates the SVN-to-Git synchronization. Tools like GitHub Actions Deploy to WordPress.org Plugin Directory handle this seamlessly.
Versioning and Releases
Use semantic versioning — MAJOR.MINOR.PATCH. Increment PATCH for bug fixes, MINOR for new features that are backward compatible, and MAJOR for breaking changes. Tag each release in Git with the version number prefixed by ‘v’ — v1.2.3.
Create a GitHub Release for each tagged version. Include a changelog that summarizes changes for users. GitHub Releases integrate with the WordPress.org deployment workflow, automating the upload process.
The Bottom Line
Git and GitHub are essential tools for professional plugin development. They enable collaboration, protect against mistakes, and automate repetitive tasks. The investment in learning Git workflows pays for itself in the first crisis it prevents — and for a business plugin, that crisis is always coming. Set up your repository, establish your branching strategy, and automate your testing and deployment. Your future self will thank you.
