An axios-API-compatible light wrapper over `fetch`, by @developit.dev: github.com/developit/re... Can act as a stopgap replacement while migrating away from axios.

What if a signal on the server could just be a signal on the client? Wrote about mixed-signals by @developit.dev - a library that reflects server-side Preact Signals to clients in real-time. No fetch calls, no deserialization, no cache invalidation. Just signals on both sides of the wire.

Show Preact and signals some love over at @npmx.dev npmx.dev/package/preact

Think prefetch is not enough, but prerender is too risky for your site? Well then check out "prerender until script"—a new option we're testing for the Speculation Rules API now available for you to test on your site with an origin trial! developer.chrome.com/blog/prerend...

OPEN YOU'RE EYES 👁️👄👁️

🎉 Preact 11 beta is here! After years of thoughtful development, we're delivering major improvements with minimal breaking changes. Better hydration, forward refs by default, and performance upgrades - all while maintaining the stability you love about Preact X.

added grouped updates to the preact signals devtools 🎉 thanks to @jovidecroock.com and the team for being open to early contributions 🙏

pnpm v10.16.0 adds "minimumReleaseAge", a setting for defining how long a version has to have been published before pnpm will install it. A nice countermeasure against accidental installs of short-lived compromised packages before they get taken down. Not a 100% fix, but a great additional step!

gradient.style has finally - come out of beta - offers multiple background editing - is open source 🎉 nerdy.dev/gradient.sty...

⚓️Oxlint with type-aware linting is here ⚓️ ◆ 40 type-aware rules supported, including the famous `no-floating-promises` rule ◆ Built on top of `tsgolint` and `ts-go` ◆ Brings speed improvement & correctness Read more in the latest announcement voidzero.dev/posts/announ...

Is there really no good standalone (no framework used/bundled) combobox web component????

YouTube Music UI is 100% vibecoded. Brutal

Oxlint is making a huge step forward! Two new updates: JS custom rules, with ESLint compatible API are on the way. The first prototype gives a good speedup already! 🔥 Type-aware rules. Full coverage no-floating-promise through tsgolint, integrated like the other oxlint rules and extremely fast.

Starting my new role on Monday. Could be anywhere.

I released the Preact-MCP, it's already a great tool. It can help you work with preact/signals/preact-iso/.... everything in our ecosystem. Check it out at github.com/JoviDeCroock...

Really nice explanation/walkthrough of Preact with Signals, start around 38 minutes if you know Preact already 🤩 - the end result is also super clean!

I made preact faster _and_ smaller today! 🍻

woo! the preact eslint config is now ESM only with flat configs 🎉

I've released the first version of my Preact animation library, built on Preact Options API, motion/mini, and WAAPI. Check it out! www.npmjs.com/package/prea...

Well, I had fun.

Spent 7 years in the GraphQL ecosystem. Here's what we got wrong: ❌ POST'ing documents as default ❌ Selling "versionless" APIs as realistic ❌ Ignoring HTTP caching entirely ❌ Making it complex for beginners ✅ The tech is solid. The guidance needs work. www.jovidecroock.com/blog/graphql...

Yesterday I was on the @learnwithjason.dev show, despite me not being great at ... speaking... 😅 I really enjoyed the explanations we got to especially the signals part youtu.be/6pBMaaX4jIg?...

ECMAScript excitement 😉 Congrats to @nicr.dev @ryzokuken.bsky.social on landing support for TC39 Stage 3 `import defer` (Lazy Evaluation) in upstream TypeScript heading for TS 5.9 🎉 Thanks to @jakebailey.dev @danr.bsky.social @chronicles.org Wes Wigham for the reviews 👍 github.com/microsoft/Ty...

65/144 goes to @drewigg.bsky.social who is a brilliant mind, very cool dude and one of my favorite people in the open source community, he also works on Preact which is one of my favorite tools of all time — thanks for being a studio friend and inspiring me to be better see more at flagpost.org

It's so nice to see a cross-framework component library and .... built on top of Preact! It's amazing, big props to the team!

Shopify Polaris is now built on web components. My team and I have been working on this for a while and it's been a lot of fun to "embrace the platform"! shopify.dev/beta/next-ge... Lots of things learned, lots of fun edge cases discovered (hello moving web components to iFrames in Firefox)

NPM downloads of course signify very little and are heavily inflated by CIs and scrapers, but... it looks like Preact has exceeded 6m downloads per week which is pretty neat: npmtrends.com/preact

At Preact we love real-browser testing, our whole test suite ran in karma for the last few years. Recently we switched over to @vitest.dev and we absolutely love it, we love it so much that we published vitest-browser-preact. It's a library that contains tools to test Preact in vitest browser mode.

Introducing @preact/signals-utils and @preact/signals-react-utils - a collection of helpers that make working with signals easier! These utilities help you write cleaner, more declarative code while maintaining optimal performance.

I am working in something *very* wild for Preact, which I believe will be a complete game changer. Actually right now I'm on vacation BUT when I get back I will continue working on this *very* wild thing. 6 year old idea but the last 2 years of Preact features make it infinitely better.

Let me also take this opportunity with Preact being a hot-topic now that I write about Preact topics on my blog! If you want to know more about the new diffing algorithm, you can look at the source code and read a few of my articles!

This, we need more kindness around these ‘tribes’. All of us working on these tools put a lot of time and love in it, all of us have our reasons to prefer working with x or y. Let’s be accepting of that!

One thing I'm really thankful for in the Preact ecosystem is that we don't have a bunch of folks saying things like "why aren't you using Preact?" every. single. time. another framework is mentioned, it adds nothing and only bums everyone out. OSS authors shouldn't have to defend their choices.

The Chrome DevTools Performance panel just leveled up! 🚀 Here's a 69-second taste of the new hotness.

Released 1tuner.com v3 - a complete rewrite in Preact/Typescript on Vite, using Preact Signals and idb 📻🎉

can always tell when a "native" app is built with react native. none of the animations are smooth and they literally never respect the OS accessibility + motion settings. not sure why people use this stuff.

in Chrome 135 - Tomorrow Mar 26, 2025 customize all the parts of a <select> with #CSS! ⤷ nerdy.dev/customize-a-...

Skew based diffing has been one of the biggest changes in the Preact diffing algorithm, for people curious as to how it works... www.jovidecroock.com/blog/skew-ba...

the google tasks API is fun

Speeding up the JavaScript ecosystem part 11 is here! This time we're looking at: Extending Rust tools with JavaScript plugins marvinh.dev/blog/speedin...

COMING SOON: Experimental @vite.dev Environment API support in React Router v7. Check this out — a single `vite build` command can co-ordinate a full client + multi-server build. Previously this was only possible via the `react-router` CLI. We're “just a Vite plugin” again 😎
