If you haven't tried the codelabs for INP from this year's I/O I highly suggest giving it a shot!

Have you heard about the Speculation Rules API but not found time to implement it on your website yet?

Well, we published a codelab for Google I/O to walk you through it on a demo site so you can see how easy it is to implement:

Try it out!

Really excited to see this report updated! Very interesting new sections on INP, bfcache, and pre-render.

Knowing which interactions to optimize for INP is made infinitely easier when you're guided by real-user diagnostics

malchata.htm's I/O video just landed and it covers how to use web-vitals attribution to take the guesswork out of INP debugging

We're exited to announce an integration with the Web Platform #Baseline project, which will help web devs understand how RUM data intersects with Baseline features. Check out the data in the #RUMArchive Insights!

As a pre-Google I/O warm up we've just released web-vitals v4.

See the below thread for all the improvements.

And, later this week, check out malchata.htm 's talk for Google I/O where he'll be explaining how to use some of these to improve INP

This is so cool!

I am giving a talk about Flexible Architectures at Web Performance NY in two weeks - hope to see you all there.

Hi, hello, we don’t have evidence of extant vulnerabilities, and haven’t been notified of anything. We follow responsible disclosure practices, and closely monitor [email protected] + respond & fix any valid issues quickly. So if you do have more info hit us up! But beyond

We’ve just published a v4 release candidate of web-vitals.js:
npmjs.com/package/web-vi…

We’re not planning any further changes so if no issues or bugs are reported then we plan to release v4.0.0 in the next week or so.

This is really really good!

Thanks Brendan Kenny!

LoAF documented on MDN!

Including browser support (which also then feeds through to Can I Use...).

It’s marked as “experimental” as per MDN policy until at least 1 other browser engine supports it, but it’s fully shipped in Chrome and ready to use to help you debug your INP issues.

Are you on top of the new Core Web Vital, Interaction to Next Paint (INP)? I'll be talking about this @WebExpo, May 29 at 4pm, in Prague.

Let's explore the transition from First Input Delay (FID) to this new metric, hope to see you there. webexpo.net/sessions/break…
