My talk at @nextjs.org Conf 2025 is now available! I cover composing client and server components, structuring component-level architecture, and using the new Next.js 16 “use cache” directive to handle static and dynamic content efficiently. www.youtube.com/watch?v=iRGc...

Nearly two years ago I became a father and whilst I wouldn't change it for anything, it's also been a hugely challenging two years for me and my wellbeing. Turns out writing about it helps, and I hope maybe it might help others: adadwhowrites.com

Cannot think of even one single time I've ever wanted to "paste with formatting"

How do you do local storage in React in 2025? All of the examples I've found so far either break the rules of React (e.g. impure state initializers) or use `useSyncExternalStore` which has poor performance and doesn't interop well with transitions.

The GitHub PR “N hidden items, Load more…” UI is one of the *most* annoying things about its interface—and that says something! When I am working with a large, long-running PR (and yes, there are valid reasons for those!) I’d like to just be able to read the whole dang thing, please and thank you!

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?

My favorite thing about infinite scroll is when your connection hiccups and nothing else will load so you have to reload the entire page and scroll a dozen times just to get to where you were so you can start the fuck over and hope your connection doesn’t hiccup again.

VS Code pro-tip: check the `@id:chat.disableAIFeatures` setting. (It’s more getting in the way than helping me, so better to just get rid of it all together)

Some birdy (thanks @tunetheweb.com) told me that Chrome supports split views behind a flag. 😲 Good stuff! chrome://flags#side-by-side

#PerfNow request throttling is behind a flag in Canary right now, you can enable it in chrome://flags. But please be aware it's not fully feature complete yet and still being worked on! However it is coming to Chrome stable in the future 🙂

I am looking for a full-time job. Being independent in open source for 3.5+ years has been wonderful. I've gotten done most of the high-level goals I wanted to, and miss having people & structure around me. If you know of a role for a staff-level TypeScript+web developer, let me know! 🙂

There’s a new type of CSS scroll-state query coming: “scrolled”. This one remembers the last direction you scrolled into, which you can use to build “hidey bars”: when scrolling down (or having scrolled down), the hidey bar hides itself. When then scrolling back up, the hidey bar reveals itself.

Yeah everyone is hearing about AI in the workplace right now, and everyone has coworkers or bosses that have fallen for the hype of AI Take a moment to realize how little it’s actually changed the work that needs to be done. How things are progressing largely at the same pace they always have

I think we all know better than to use an accessibility overlay because they are complete rubbish, but that doesn’t stop stakeholders asking to cheat with one. This fact sheet will give you the facts to rightly, fight back. overlayfactsheet.com/en/

✨ New post There is a lot of chatter about the CSS resets recently. Here is my take. Enjoy 🫶 “The CSS Reset, again” pawelgrzybek.com/the-css-rese... #css

⚛️ReactConf once again mentioned concurrent stores. What if I tell you, we have concurrent external stores today? (kinda) My latest blog post explains: 👉 How to to pair `useSyncExternalStore` with `useDeferredValue` (and `useMemo`) ⚡ Why this can improve UX & INP during hydration

Can anyone explain this behaviour with `useEffectEvent`? I'm seeing stale closures which I thought should never happen? stackblitz.com/edit/github-...

@ricky.fm 👋 Hey Ricky, loved your talk! Is there somewhere I can find the demo code to play around?

AI coding sucks CJ just one-shotted a 15 min rant and it's incredibly refreshing. www.youtube.com/watch?v=0ZUk...

We’ll get there 😂

@en-js.bsky.social 👋 Do you know what changed between babel-plugin-react-compiler 19.1.0-rc.3 and 1.0.0? I can't find a changelog anywhere… I'm asking because our bundle size has increased again and I'd like to understand why (presumably better memoization).

I'm trying to combine React Actions + useOptimistic + React Query but I'm seeing some odd behaviour. What's going on here? I suspect it's because React Query uses useSyncExternalStore. Does that mean it's incompatible with Actions? codesandbox.io/p/sandbox/re... cc @tkdodo.eu @ricky.fm

Last week, I had the immense honor of speaking at one of my favorite events, @beyondtellerrand.com. (🤯) My talk “Painting With the Web” is now available on YouTube. I hope you like it! 🤗💚 www.youtube.com/watch?v=1Pq7...

React 19.2 is now available! This release includes Activity, useEffectEvent, React Performance Tracks, partial pre-rendering, and more: react.dev/blog/2025/10...

Politics isn't manipulation and backstabbing. It's understanding how decisions actually get made and learning to navigate that reality. Refusing to engage doesn't make politics go away. It just means you lose by default. terriblesoftware.org/2025/10/01/s...

Imagine if useReducer could have side-effects, like a POST request. It would need to order calls so you know the “previous” state to pass the reducer. It would also need a pending state so you can show a spinner while it’s updating. Now you understand useActionState.

DHH is the biggest reason why I don't use Rails anymore. This post (and especially the linked talk) get to the heart of hte problem. davidcel.is/articles/rai...

React innovates in scheduling Other frameworks focus on DOM update performance Scheduling has a much greater impact! Everyone should read this thread to understand React's true competitive advantage.

The thesis of this post is that React isn't innovating and other UI libraries are. But the real issue is that React's innovations are overshadowed by it's own success. www.lorenstew.art/blog/react-w...

@ricky.fm I have a "Suspense-enabled router" and a form "Action". Whilst the form Action is pending, none of my router links work, rather they wait for the form Action to complete. Is there a way around that? I would expect links to interrupt the form Action. codesandbox.io/p/devbox/rea...

With all this talk about resets, there’s one idea I think more people should be talking about: Reset all block elements to column flexbox. github.com/dwhieb/flexb... cc @kevinpowell.co @chriscoyier.net

Flickering UIs? Race conditions? 🤔 @aurorascharff.no shows how to tame async chaos with @react.dev 19 Actions, `useOptimistic`, server components & view transitions! Check out her must-watch talk from React Universe Conf 2025 👇 youtu.be/I3AsmAWWGEs?...

@tkdodo.eu Hey! Are you aware of any examples of using React Query mutations with React’s “form actions” (e.g. inside useActionState) and/or useOptimistic?

@ricky.fm Is there a way to make a state update inside a form action run sync? E.g. I want to show the toast immediately when the button is pressed: codesandbox.io/p/devbox/lau... Currently I have to force the state update to run in the next tick so it runs outside the transition, but feels hacky.

Leadership in technical environments isn't about being the smartest person in the room. It's about being the most effective translator. Best thing I’ve read this week:

Is there any indication when @rspack.dev/Rsbuild might get RSC support? Notably absent from rsc.krasimirtsonev.com, the React Router docs suggest either Vite or Parcel instead, and of course alternatively there's Next's Turbopack.

I added parallel and recursive route rendering to Twofold, which kind of blew my mind. It's the first time I've used a React pattern that specifically takes advantage of the two phase server/client render. Wrote about it here: twofoldframework.com/blog/paralle...

I got into tech because it’s fun to take things apart, see how they work, and put them back together — or rearrange the parts into something brand new. it definitely feels like the new ethos is “bro why bother to learn? caring about that stuff is cringe, just go FAST bro” and that bums me out

I've been a lazygit power user for years and I honestly adore it, but after trying Jujutsu + jjui for the past week, I don't think I'll be going back. 1st class support for stacked branches, stable change IDs, non-blocking conflicts, support for commits with more than 2 parents, and so much more.

@ped.ro Is there a way to paste into Raycast Notes without formatting? I hoped ⇧⌥⌘V might do it but seems not.
