    • INP opportunities research
    • Interactivity APIAPI An API or Application Programming Interface is a software intermediary that allows programs to interact with each other and share data in limited, clearly defined ways.

Notes from today’s meeting:

  • @westonruter For Interactivity API, I’ve continued providing feedback for the pull request that adds server-side processing of directives. It’s almost there! This will be great because it will mean that client-side JSJS JavaScript, a web scripting language typically executed in the browser. Often used for advanced user interfaces and behaviors. will have to do less, resulting in better metrics likely for LCP, CLS, and INP.
  • @adamsilverstein I have been working on researching INP opportunities using httparchive queries in a colab which I plan to summarize in a doc to share with the team. I have made good progress and hope to have a summary to share next week.
  • @westonruter Also I identified an issue where passive event listeners can’t currently be added via event directives
  • @thelovekesh is ready for final review. Also as mentioned by @joemcgill to release this module as standalone 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.
