Welcome!

The WordPress coreCore Core is the set of software required to run WordPress. The Core Development Team builds WordPress. development team builds WordPress! Follow this site for general updates, status reports, and the occasional code debate. There’s lots of ways to contribute:

Found a bugbug A bug is an error or unexpected result. Performance improvements, code optimization, and are considered enhancements, not defects. After feature freeze, only bugs are dealt with, with regressions (adverse changes from the previous version) being the highest priority.? Create a ticket in the bug tracker.

Want to contribute? Get started quickly with tickets marked as good first bugs for new contributors or join a bug scrub. There’s more on the reports page, like patches needing testing, and on feature projects page.

Other questions? Here is a detailed handbook for contributors, complete with tutorials.

Below is a summary of this week’s JavaScriptJavaScript JavaScript or JS is an object-oriented computer programming language commonly used to create interactive effects within web browsers. WordPress makes extensive use of JS for a better user experience. While PHP is executed on the server, JS executes within a user’s browser. https://www.javascript.com/. chat (agenda, Slack Transcript). Have a topic for discussion for the next meeting?

Webpack pluginPlugin A plugin is a piece of software containing a group of functions that can be added to a WordPress website. They can extend functionality or add new features to your WordPress websites. WordPress plugins are written in the PHP programming language and integrate seamlessly with WordPress. These can be free in the WordPress.org Plugin Directory https://wordpress.org/plugins/ or can be cost-based plugin from a third-party to extract script dependencies

Another update was shared on a Webpack plugin discussed during the previous week’s meeting, which helps provide automation for the tedious and error-prone task of manually maintaining script dependencies. The pull request was merged this past week: PR#14869. It won’t be published to npm until WordPress 5.2 is released.

There’s a follow-up issue at PR#14837 which aims to replace the existing manually maintained packages-dependencies.php file in GutenbergGutenberg The Gutenberg project is the new Editor Interface for WordPress. The editor improves the process and experience of creating new content, making writing rich content much simpler. It uses ‘blocks’ to add richness rather than shortcodes, custom HTML etc. https://wordpress.org/gutenberg/. There’s an open question there about how we handle “legacy” scripts which are still referenced on the window global, as these aren’t explicit but rather implicit dependencies. We discussed several possible solutions and decided to take the following steps:

We know what these implicit dependencies are and which scripts depend on them, let’s merge those into the “extracted” set? There is already a follow-up PR#15124 opened (shortly after the meeting) by @jonsurrell.
We were all in agreement that referencing the window globals is itself a problem we need to address. This is incompatible for use in an npm context and should be eliminated or substituted with an equivalent package. @aduth created an issue#15125 to keep track of it.
