👀 Document Picture-in-Picture API - Now in Firefox 148 nightly

It allows presenting a window that remains on top.

It's useful for videos already, but we want to be able to render any DOM element here

There’s still time to complete the State of React survey, if you haven’t yet!

These surveys are both a community service *and* a great way to learn about modern React features. Win-win 😄

useEffect + fetch()

Last week, we linked to an useEffectEvent() that was quite incorrect 😅

If you read it, please forget what you learned because it's wrong

I have a theory that, given enough time, React Native will eventually become a browser.

Am I the only one?

There is critical vulnerability in React Server Components disclosed as CVE-2025-55182 that impacts React 19 and frameworks that use it.

A fix has been published in React versions 19.0.1, 19.1.2, and 19.2.1. We recommend upgrading immediately.

_Very_ excited to announce that @mweststrate.bsky.social just published Immer 11.0 with the major architectural rewrite I did to improve perf! 10.2 already had several smaller tweaks, and there's one more PR up to add optional array overrides:

Wow, looks quite useful for React streaming and Suspense
Out-of-order HTML patching, another proposal from TPAC, lets HTML be presented non-linearly, and a single file can update multiple parts of the page.

Would this feature be useful to you?

Reposted by Seb ⚛️ ThisWeekInReact.com
We've been working on a few proposals we'd like to bring to the web platform to make it easier to have more seamless navigations between pages.

@nomster.bsky.social @foolip.org and @dbaron.org presented these at W3C TPAC annual meeting last week
