Thank you to whoever liked @nuqs.dev on @npmx.dev 🫶

🟣 I'm live on Twitch! Looking at the Fastify vuln, working on nuqs & yapping about OSS, come say hi! 👋 twitch.tv/francoisbest

TIL about the .extend builder pattern to add context to test fixtures in @vitest.dev Seems super handy for backend testing (setting up servers, database, mocked services etc). And now with type safety? 😍

I need to dive deeper into the @react.dev Activity component (particularly the @nextjs.org cacheComponents implementation), having two routes mounted in the DOM on navigation is wreaking havoc in e2e locators and makes it hard to reason about URL state updates (which page sees what URL as the SoT).

📦 [email protected] is out! 🚀 🐞 It fixes a bug with @nextjs.org app router where URL state would leak during navigation (destination page pre-rendered with the source page's search params). Try it out: pnpm add nuqs@latest

✍️ I wrote a short opinion piece about a pattern I keep seeing lately: switching to the smallest responsive layout too early. I call it The Too-Early Breakpoint. 🔗 ishadeed.com/article/too-...

📦 [email protected] is out! 🚀 🐞 It fixes a bug with @reactrouter.com 6/7 & @remix.run with Link & Back navigation, where the source page would briefly re-render with the destination URL state before unmounting. Try it out: pnpm add nuqs@latest

So happy to be back at #ReactParis this year! 🙌 Talks are good to quickly introduce concepts, but workshops are a better format to go deep into architecture decisions, advanced patterns, and practical use-cases. Looking forward to seeing y'all in Paris! 🇫🇷🥐

"Choose your future", "We should all have a say" → No choice being given, no way to give feedback. Looks like there is no future for @mozilla.org down that road.

Last week I lost my job. It took me a while to process... If you or your company needs an experienced full stack developer who understands how the web works, knows modern tech, communicates well, please reach out. My CV: pawelgrzybek.com/cv/ I'd appreciate if you could share. Thank you.

Passing the 1K mark felt amazing, then the star count started losing its meaning (downloads are more relevant). But 10K kicks it back into the excitement zone. Onwards 🚀

🙋‍♂️ so ... for reasons: I would love to know people's frustrations with: - the current npmjs.com - admin user flows on npm web ui (and cli, locally) 🙏

🟣 I'm live on Twitch! Gonna be a short one, talking about OSS & music, come say hi! 👋 twitch.tv/francoisbest

🟣 Live streams are back! (after two weeks of conference & post-conf flu) Tomorrow Friday 11am CET, we’ll cover: - A little change of scenery - Cool things I found at #Snowcamp last week - A big announcement (hopefully 🤞) Come say hi! You won’t want to miss the start 👀 twitch.tv/francoisbest

🆕 npx unbarrelify At last, an easy way get rid of barrel files! Rewrites consumers to import directly from source, then deletes the barrels. Safe and fully automated, read all about it at github.com/webpro/unbar...

The Mothership is reconnected 🤘 A little work to do to shorten the desk, and I can move it to the other wall for a nice background for live streams (maybe we can do some music too while the agents are working).

Weekend thoughts on Gas Town, Beads, slop AI browsers, and AI-generated PRs flooding overwhelmed maintainers. I don't think we're ready for our new powers we're wielding. lucumr.pocoo.org/2026/1/18/ag...

I'm giving up on getting those models to output correct React code. - useEffect spaghetti everywhere - state sync - forwardRef in React 19 I might use them for other tasks, but for things that I actually know how to write, it's just not worth it. I'm so tired. 😓

Oh that's handy!

No wonder I feel rough after conferences 😷🤧

Next we have @sinedied.bsky.social with genaiscript, an AI-native JS-based scripting environment. Think Google zx meets LLMs. The demos in how to make smart scripts to help you with OSS maintenance resonated a lot with some of the problems I’ve encountered.

Great lightning talk by @gouz.dev about how they generated hiking maps from @openstreetmap.bsky.social.

I’ve got a feeling @permacodeur.fr & @uggla88.bsky.social are going to steer me back to Rust 🦀 Thanks for your talk / workshop!

Watching @mickaelalvs.dev & @slocaly.bsky.social running the @tanstack.com Query tech support phone line at #snowcamp ☎️ Hilarious, very well structured, loved it through and through ! 👏 Bonus: they used @nuqs.dev too 🫶

No streams this week, I'm at snowcamp.io, the local web dev conference in my home town 🏔️🏂 On today's menu: workshops! 🦀 Building real-time TUIs with @rust-lang.org 🙈 Navigating websites blindfolded, using only the screen reader #a11y

The Navigation API now ships in all major browsers. 🙌 Lots of other cool new things in there. Reports on the death of Firefox were greatly exaggerated.

64% of WebKit non-Apple contributions, 20% of Chromium non-Google, 27% of Servo, 39% of test262, and it goes on. And doing all this as a worker-owned, employee-run cooperative. The world would be a very different place if companies like Igalia were the norm rather than the exception in tech.

TIL @vscode.dev has a "brain workout" feature: disable AI by increments of 5 minutes.

I cancelled my Claude Code subscription (after a month). Part of it is the (now reverted) drama about Anthropic cutting access to OSS 3rd party apps (gray area here). But the biggest reason is that it works too well, and I don't want to depend on a non-OSS, locking-in tool that much. 🧵

For the longest time I tried to disable my CapsLock key on macOS (that I use as the Hyper key in @raycast.com), and there was a setting all along to do just that! 🤦‍♂️ No more accidental CapsLock activation. 🙌

I like this setting for VS Code from Ben Frain. JUST show the vertical line for the current indentation, not all of them ``` "workbench.colorCustomizations": { "editorIndentGuide.background1": "#00000001", "editorIndentGuide.activeBackground1": "#ff9900" } ``` benfrain.com/vs-code-high...

There is something oddly therapeutic about reading W3C specifications. Or maybe I'm just weird like that.

Slightly diminish a band: Sarcastic Puppy

Getting to work on both of my careers: web dev 🤝 audio engineering. This is my happy place 😊 I've got so many ideas for this audio course, to make it truly useful beyond just the theory. Can't wait to show y'all.

🟣 I'm live on Twitch! Yapping about OSS & working on @nuqs.dev, come say hi! 👋 twitch.tv/francoisbest

The Node.js package configuration guide is now live! 🎉 Whether you're creating your first package or migrating to ESM, this guide walks you through it with examples. https://nodejs.github.io/package-examples

Thank you @sentry.io for sponsoring my work on @nuqs.dev 💖

Here's a little loop to replicate the cascade of .env.local, .env.$NODE_ENV.local, .env etc that some environments use (eg: @nextjs.org), using this handy little utility from code @nodejs.org Thanks @stefanjudis.com 🙌 🔗 gist.github.com/franky47/9ce...

🟣 I'm live on Twitch! Working on my upcoming audio course "How to sound good on YouTube" and setting up my Stream Deck, come say hi! 👋 twitch.tv/francoisbest

📚 New Year, New Blogpost 🎉 Continuing my thoughts about design-systems, this one is about compound components, when they are a good fit and how to make them type-safe. Spoiler: It’s not about the `children` prop ...

🟣 I'm live on Twitch! First stream of the year, come say hi! 👋 twitch.tv/francoisbest

The @nuqs.dev types in TypeSlayer 😈 Happy new year! 🎆🎇

🥳 TypeSlayer is out! celebrate by posting what your type graph looks like! it legit has an actual leaderboard now: so bonus points if you win lol 🏆🏆 run: `npx typeslayer` source: github.com/dimitropoulo...

2025 was an incredible year for @nuqs.dev, but the best part was the friends we made along the way. 🫶 Happy new year! 🥂

🟣 I'm live on Twitch! Talking about e2e testing & playing with Waku ⛩️, come say hi! 👋 twitch.tv/francoisbest

🟣 Stream day tomorrow! I'll talk about e2e testing: - How I migrated ~300 test files from Cypress to Playwright with a little help from Claude Code - How e2e tests work in @nuqs.dev and why we need them - Adding a test suite for Waku ⛩️ alpha (road to official support) Tomorrow (Tuesday) 2pm CET

New year, new Twitch handle! Goodbye fortysevenfx, hello francoisbest 👋 www.twitch.tv/francoisbest Makes me sad to break links though, I wish Twitch could have temporary redirects until the handle is released. 😓

🟣 on Tuesday stream we'll be adding an e2e test suite for the @nuqs.dev Waku adapter targeting v1@alpha. This is the "graduation ceremony" towards becoming the 8th official adapter! 🎉⛩️
