WordPress Playground Table Focus

There are many ways to contribute to WordPress Playground depending on your background and comfort level.

  • Testing and feedback: Help test Playground features, including PR Previews V3, the new SQLite integration, and tools powered by Playground such as My WordPress.
  • WordPress Studio: Help test the new version of WordPress Studio on Linux and provide feedback on the local development experience.
  • Blueprints: Help plugin developers create their own Blueprints and enable the Live Preview button for their plugins.
  • Documentation: Improve existing docs, suggest new guides, or help make Playground easier to understand for new users and contributors.
  • Translations: Playground documentation is currently available in several languages, and translation contributions are always welcome.
  • Good first issues: New contributors can start with issues labeled Good First Issue.
  • Design, marketing, and product feedback: You don’t need to write code to contribute. Designers, marketers, writers, educators, and site builders can help review the UIUI UI is an acronym for User Interface - the layout of the page the user interacts with. Think ‘how are they doing that’ and less about what they are doing., improve onboarding, suggest new features, and identify opportunities for clearer communication.

A good quote from Jonathan Bossenger(@psykro):

Remember: it’s “Contributor Day,” not “Contribution Day.” The goal is to find meaningful ways to contribute and help move the project forward. Some work may continue after the event, and that’s expected.

What WordPress Playground Is Building

WordPress Playground lets you run WordPress directly in the browser, without setting up a traditional local server. It helps people test WordPress, try plugins and themes, create demos, review pull requests, and build new contribution workflows with less setup friction.

Some of the key areas contributors may work with include:

  • Playground web instance: The public browser-based Playground available at playground.wordpress.net.
  • Blueprints: JSONJSON JSON, or JavaScript Object Notation, is a minimal, readable format for structuring data. It is used primarily to transmit data between a server and web application, as an alternative to XML. files that define how a Playground instance should be configured, including plugins, themes, content, settings, and setup steps.
  • PR Previews: Playground-powered previews that make it easier to test WordPress pull requests directly in the browser.
  • SQLite integration: Ongoing work around improving WordPress support for SQLite-powered environments.
  • Playground CLICLI Command Line Interface. Terminal (Bash) in Mac, Command Prompt in Windows, or WP-CLI for WordPress.: A Node.js package that allows contributors and developers to run WordPress locally without Docker, MySQLMySQL MySQL is a relational database management system. A database is a structured collection of data where content, configuration and other options are stored. https://www.mysql.com, or ApacheApache Apache is the most widely used web server software. Developed and maintained by Apache Software Foundation. Apache is an Open Source software available for free..
  • WordPress Studio integration: Local development workflows powered by Playground, including ongoing testing for Linux support.
  • Documentation and translations: Contributor-friendly docs that help more people understand and use Playground across different languages and workflows.

You can learn more in the Playground documentation and the dedicated Contributor Day page.

Prepare at Home

To make the most of Contributor Day, please prepare before arriving. Wi-Fi at large events can be unreliable, and many contributors may be cloning repositories or installing dependencies simultaneously.

For most Playground contribution tasks, you will need:

  • A laptop
  • A GitHubGitHub GitHub is a website that offers online implementation of git repositories that can easily be shared, copied and modified by other developers. Public repositories are free to host, private repositories require a paid subscription. GitHub introduced the concept of the ‘pull request’ where code changes done in branches by contributors can be reviewed and discussed before being merged by the repository owner. https://github.com/ account
  • A WordPress.orgWordPress.org The community site where WordPress code is created and shared by the users. This is where you can download the source code for WordPress core, plugins and themes as well as the central location for community conversations and organization. https://wordpress.org/ account
  • GitGit Git is a free and open source distributed version control system designed to handle everything from small to very large projects with speed and efficiency. Git is easy to learn and has a tiny footprint with lightning fast performance. Most modern plugin and theme development is being done with this version control system. https://git-scm.com/ installed
  • Node.js and npm are installed
  • A local copy of the Playground repository

We recommend cloning the Playground repository before Contributor Day:

github.com/wordpress/playground

Docker and Composer are not required for most Playground Contributor Day tasks.

If you want to work with plugin demos or Live Preview support, it may also help to review the Playground Step Library before the event.

Looking Ahead

At WCEU Contributor Day, we’ll focus on testing new features, improving documentation, supporting plugin developers with Blueprints and Live Preview, reviewing the user experience, and helping new contributors find their first meaningful contribution.

Contributors whose pull requests are merged may also be eligible for the WordPress Playground contributor badge on their WordPress.org profile. If you’re interested in Playground but unsure where to begin, join us at the Playground table or ask in the #playground Slack channel.
