📦 [email protected] is out! 🚀 Two rapid-fire PRs by @tkdodo.eu 🔥 - Fixed a bug with MultiParsers & history: push - Prevent a re-render when doing setState(x => x) (same reference) in useQueryStates Try it out: pnpm add nuqs@latest

🗣️ My talk "Decluttering Sentry - One Knip at a Time" from @react-prague.bsky.social is now available on YouTube ✂️ This is a real-life story (with ups and downs) about how we used knip by @webpro.nl at @sentry.io to delete 20k lines of unused code and now run it in CI so it never happens again 🎉

It turns children into siblings 🤯. @ryansolid.bsky.social blowing every React dev's mind with nested data fetching and fine-grained reactivity 🔥 www.youtube.com/live/fnyK-xX...

ESLint v10.0.0 is coming! Check out our latest blog post for what to expect. https://eslint.org/blog/...

L take. tabs are objectively better for developer a11y. www.reddit.com/r/javascript...

I remember when prettier came out and we tried it on a project, I called it "uglier" and removed it almost immediately. Little did I know that it mostly doesn't matter _how_ you format something - what matters is that everyone uses the same style. In that sense, prettier is goated 🐐.

Should we be esm only in the next major version?

Having fun with `act` again. Honestly this concept never clicked for me 🤷‍♂️

I have no idea how TypeScript and React works together 😂. Stumbled upon `data-*` attributes on a simple component and can't make it work when using the props object of that component. Why is that erroring, and what's the fix? AI is useless for this: www.typescriptlang.org/play/?ssl=11...

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

First time using knip.dev for a client, not bad (-26 unused files)

📦 [email protected] is out! 🚀 - MultiParsers: `parseAsNativeArrayOf`, and turn key repetition into Record, Map, Set, anything, with custom parsers. Thanks @tkdodo.eu ! 🙌 - Fixed a bug with flickering optimistic state on update Try it out: pnpm add nuqs@latest

It took a bit of time, but @tanstack.com query now has support for @svelte.dev 5 🎉 Huge shoutout to @lachlancollins.bsky.social for working on this as well as the big blocker - versioning 🙈

Now is the best time to try out @tanstack.com Start and give feedback on the RC 🙌

📦 [email protected] is out! 🚀 ✨ MultiParsers allow transforming repeated keys in the URL into more complex data types. This had been a long-requested one, thanks @tkdodo.eu! 🫶 🧪 The testing adapter gets an optional memory to behave more closely to real frameworks. Try it out: pnpm add nuqs@beta

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:

I was today years old when I learned that if you have an unbound generic T and a variable that is T | null and you do a control-flow narrowing by checking if (variable !== null), you’ll wind up with T & ({} | undefined) which is so weird but somewhat logical as T could contain undefined in the union

We’re live!! My brand-new course, “Whimsical Animations”, is now available. 🥳🎉 whimsy.joshwcomeau.com I’m so excited to share all of my animation tools and techniques with y’all. 😄

🚀 Announcing TanStack.com Start v1 Release Candidate! Upgrades ↓ ✨ Unified Route Tree: no more server-specific files 🔐 Type-safe middleware & server context upgrades 🛡 CSP/nonce support ⚡ Now works with any native Vite Env plugin 🌀 Zero-JS: any server handler can render!

I have been using TanStack for years, but I got some amazing lightbulb moments during this course. Highly recommend. TanStack has helped me build lightning-fast tooling for FinOps at work, and I love using their libraries. #react #tanstack ui.dev/certificate/...

"We will build it ourselves so we won't have any dependencies" I've seen that costly mistake way too often. Building it yourself maybe doesn't add to the dependencies array but it's a dependency nonetheless! And no-one but your team to rely on for maintenance and expertise.

I wanna write a blogpost about Suspense, Transitions and React Query but it would mostly be "here's how I understand it, here's what I think doesn't work and here's what we might have to change internally to make it work"

Proud to have contributed this feature to @nuqs.dev ❤️

So I'm not getting notifications for replies to posts where I'm explicitly mentioned here? Why? I have all notification settings set to "In app, everyone"...

Turns out naming is hard, who would've thought, huh 🤔

Some people are just here for the "drama" I guess so they really want there to be a feud and cannot comprehend that this is not how OSS works. People who do things for free and for fun usually don't fight with others who do the same. Why would we?

✂️ Come on let’s knip again, like we did last summer ... 🕺 🎶

Excited to run my React Query – Beyond the Basics workshop at @reactadvanced.gitnation.org, Nov 27 in London! 🎉 If you know the fundamentals & want to level up with prefetching, cache seeding, persistence & smooth UX, this one’s for you 🚀. Hope to see you there:

Shout-out to our speakers: @mironcatalin.bsky.social, @tkdodo.eu, Zarif Abdalimov, and @chmal.it.

✂️ Come on let’s knip again, like we did last summer ... 🕺 🎶

@ricky.fm I had an idea: React Query exposes a notifyFn that wraps all internal updates; it’s a noop per default, but we could pass `startTransition` here to wrap all updates in transitions. Then, if we’d always re-suspend, it should transition properly. But it doesn’t work :/

Had a great time walking around Prague and meeting @kettanaito.com for lunch to talk about open source, giving workshops and life in general. Thanks for showing me around @kettanaito.com ❤️

Didn't know there were so many hills and stairs when walking through Prague 🥵

This is how my stress levels look right after being on stage. My watch thinks I was exercising 😂

Thank you @react-prague.bsky.social 🙌

The Productboard office in Prague is impressive. Great place to have a meetup 🙌

Trying to login to the Discord web client on train wifi is not going great. Their main JS bundle is 20.3MB minified and contains week and month name translations for 126 locales!! WHY?

Never knew what a bad experience the GitHub notifications page is as I usually don't use it. Like why does the All/Unread filter button just disappear when I use one of the predefined filters in the sidebar? I have to manually add "is:unread" to make is show up again. Really?

Tired of passing query clients to your mutation with @tanstack.com Query? Well, now you can access it in the mutationFn – github.com/TanStack/que... Thanks @tkdodo.eu for all your patience on this 🙏

🚊 On my way to Prague for @react-prague.bsky.social. I will be talking about how we use knip @sentry.io to remove unused code 🙌

🗣️ Big news: I'll be speaking at @nextjs.org Conf '25, on Oct 22 in SF ! We'll cover a few tricks @nuqs.dev has up its sleeve to scale URL state in Next.js (some I yet need to finish building 😅). So thankful for the opportunity 🙌
