Syncpack 15 adds full support for @pnpm.io and bun catalogs. Every catalog and the entries within them can be grouped, linted, fixed, updated, or even banned like any other dependency in your project. github.com/JamieMason/s... #Monorepo #WebDev #GitHub #TypeScript

Astro 7.4 ships experimental parallel prerendering. I tried it on the Astro docs (6,358 pages): build time went from 67s to 37s, 45% faster. 🚀

We're re-opening the Web Components Vs frameworks battle at our 24th September event. Hayleigh Thompson will make the case that with just a little shift on what we think a 'component' is, the rewards of interoperability are worth fighting for. 🎟️ www.meetup.com/front-end-sh... #WebComponents

❌🛢️ unbarrelify v1.1.4 is out Fully automated cleanup: unbarrelify rewrites consumers to import directly from source, then deletes the barrel files. Why? Read more at github.com/webpro-nl/un... Trust me, you don't want to do this by hand and your agent will screw up and bill you nonetheless. 👇

Scroll-triggered animations that fire once and stay without any JavaScript. The trick is using animation-play-state to pause the animation when it's out of view. www.youtube.com/watch?v=onra...

✂️ Knip v6.32.3 is out Some 🔥 fixes by no less than 8 new contributors 🧡 Still in awe how the downloads keep ramping up (2.5M/day!) — hopefully means both hoomans and agents cleaning up after 'emselves... 🧹 Watch this space, moar is coming! Changelogs: github.com/webpro-nl/kn... Knip: knip.dev

Preact 11.0.0-rc.1 is here ⚛️ preact/compat code is now tree-shakeable, with representative single-export bundles shrinking by up to ~28%. Plus: more size wins, better HTML attribute types and maintenance fixes. This will most likely be the last rc - feedback is appreciated

A New Color (1/5🧵)

With Chrome 151, soft navigations entered the mainstream. If you haven't heard the term, a soft navigation is anything that: - is initiated by a user action - results in a visible URL change - results in a visible paint https://developer.chrome...

Post a perfect album from the 2000s:

⏪ 24 hours ago, supporters groups representing millions of fans globally launched a petition calling for Infantino to resign & reform in #FIFA. 👏 Since then, 30,000+ fans from around the world have backed it. ✍️ Add your voice now: change.org/infantino-out-now #InfantinOUT

🦀 ImageOptim-CLI 4.0.0 is now written in Rust. This version should not only be faster, but also much smaller than previous versions. Nothing else has changed, the API is the same #WebPerf #WebDev

Astro 7.2 is out now! Experimental incremental static builds are here: only re-render the pages that actually changed and watch your build times drop. Plus opt-out session support, background astro preview, and relative logger entrypoints. astro.build/blog/astro-7...

🎤 Have something to share? We're looking for lightning talks for our Fronteers meetup on Sept 10th in Utrecht! Five minutes. One idea. That's all it takes. Submit your proposal: forms.cloud.microsoft/e/gzU9UEFaqN Join the meetup: www.meetup.com/fronteers-nl...

I think it's worth sharing the progress of my lottie compiler here: github.com/cometkim/ulo... You can test it on the demo page, which now has a live output preview in the breakdown section.

I'm going through a backlog of ~220 links to Design Systems things for the newsletter before the #HungarianGP. Seems I've written quite a bit since the last newsletter was sent out :lolsob: You can sign up to get the emails and check past issues here: https://news.design.systems 🙏🖤

Another great post by @joshwcomeau.com. I love that he didn't try to cover the whole API, but made a pragmatic decision to explain the most useful bits. As always, I learned a lot from this post. www.joshwcomeau.com/css/anchor-p... #css

If you make websites for a living, stop what you're doing and read this research by @tammyeverts.com; it shows what many of us have been saying for a long time: even if there is such a thing as "fast enough", it's generally *much* faster than you are targeting: embrace.io/blog/research-co…

If you are on the latest pnpm v11.10.0 (or v10.34.5), you can try out the pnpm v12 alpha via: pnpm self-update 12.0.0-alpha.5 It is fully in Rust! 🦀

Playing with `focusgroup` support in Chrome 150 and I like seeing the browser assign role based on the `focusgroup` token. Yes, you can override with explicit `role`, which will undoubtedly happen as devs choose kbd patterns that don’t match the role. But still neat. codepen.io/aardrian/pen...

Does your design system have a rulebook? Not just what was decided but why, and what was rejected. With AI working inside design systems, undocumented reasoning is a gap the model will fill on its own. Great piece by Kevin Muldoon on the three kinds of truth every system needs: hubs.li/Q04f6BFv0

The new Rust compiler in Astro 7.0 is COOL but it also changes how some things are rendered. I wrote about the whitespace changes here! cassidoo.co/post/astro-7...

From the archives: Jason Bradberry challenges the ideals of displaying your entire navigation as a cluster of links and presents a case for exploring off-screen menus where the context is right for it. piccalil.li/blog/in-prai...

Inspired by @meyerweb.com's talk at @cssday.nl I played with offset-path before, but somehow missed that we can use it with border-box and padding-box, making this so incredibly easy. I need to fix up the code a bit as it's kinda messy, but you can see it here: codepen.io/editor/kevin...

I'll be delivering a talk about ARIA's history and structure, as well as providing guidelines and busting myths for #WebExpo in about two hours' time. If you've got FOMO you can read the article that this talk was sourced from: www.smashingmagazine.com/2025/06/what... #a11y

An article by the Designers in my team, this is what I've been working on at Monzo monzo.com/blog/reimagi...

npm increasingly feels like a zombie org under GitHub. As someone who's been around the JS ecosystem and part of multiple OSS orgs for years, what I'm seeing isn't just "big co moves slow." It's quiet neglect of critical infrastructure the entire JS world runs on. A short thread 🧵

Our 28th May #FrontEndSheff meetup is this Thursday - feat. Thomas Baker, David Warrington and their insight into styling systems and TypeScript validation. More excitingly: we're sending our organisers a bit earlier to Charles St. to figure out the aircon 🧊 www.meetup.com/front-end-sh...

the @e18e.dev npm publishing guide has been updated to recommend the new `npm stage` feature! this guide and the templates it offers are a good way to get setup quickly in a secure way

I've no idea how but I've got the Pugwall theme stuck in my head, and maybe now you do too.

Here's the recording of this year's “What's new in Web UI” talk @una.im and I gave at Google I/O earlier this week. youtu.be/uT7MVcCQ4rw Very happy with how it went, and I think you might find it useful, so give it a watch 😊 #ChromeDevRel #GoogleIO

Get your tickets to @perfnow.nl before prices rise on July 1st! I say this every year and I will continue to say it: there is nowhere better to learn about #webperf 🚀 The speaker line-up is always absolute gold and the hallway track is just as valuable.

Did you know `AbortSignal` has a `timeout` static method? Pass `AbortSignal.timeout(5000)` straight to `fetch` and bail after 5 seconds. All without a hand-rolled `setTimeout` + `AbortController` dance. https://developer.mozill...

Woooo yeaaah! The missing piece 🎉 everything is about to get a lot more secure

So here's an interesting little thing or 2 @nomster.bsky.social , @foolip.org , and myself have been cooking up—along with lots of help from others!: developer.chrome.com/blog/declara... This could lead to some VERY interesting changes in how we write web pages. Would love to hear your thoughts!
