  • @weston has been working on adding async/defer to more places in core
    • Merged this PR that used defer for all block view scripts
    • Committed the use of async for the comment-reply script in core
    • Proposed adding defer to the wp-embed script, even though his analysis didn’t show much performance benefit.
  • @weston reported that now that HTTPHTTP HTTP is an acronym for Hyper Text Transfer Protocol. HTTP is the underlying protocol used by the World Wide Web and this protocol defines how messages are formatted and transmitted, and what actions Web servers and browsers should take in response to various commands. Archive has custom metrics for WordPress scripts, he’s been starting to dive into doing queries for how well sites are using the scripts 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., including to what degree they’re using $in_footer and how many are currently using async and defer even before our official way of doing so
  • He’s also been doing some research into which specific plugins are responsible for those blocking_in_head scripts. So we’ll have some opportunities for ecosystem outreach hopefully soon
  • Review/feedback on his HTTP Archive queries would be appreciated
    • Later in the meeting, Weston followed up to share that Felix had identified a flaw in the query he was using go get counts of scripts using async and defer from the HTTP Archive. He plans to revise and share updated results
