Watch out! Chrome has a huge bug with <input type="number"> which causes values to change unexpectedly. It's fixed in Chrome 150, but that won't land until the end of June.

Today I’m launching Vite Deploy! A minimal deployment primitive for @vite.dev apps: deploy anywhere, whether your app is static, server-rendered, or both. It’s designed to integrate easily with other tools: Hono, @tanstack.com Start... Check it out: vite-deploy.web-runes.dev

The latest Playwright release can snapshot your accessibility tree Great to avoid a11y regressions 👌

Fresh Starlight release, fresh batch of plugin updates. All my Starlight plugins are now 0.39-ready and already using the latest improvements.

A feature-packed release for the Starlight OpenAPI plugin: - operation snippets for cURL, JavaScript, Rust, and more - autogenerated request body examples - autogenerated response examples

Building on recent improvements, the Starlight Links Validator now includes more features useful for large documentation sites like Cloudflare Docs: - choose if link validation errors fail the build - JSON error reports for external tooling - GitHub Actions step output github.com/HiDeoo/starl...

"Open source is not just about code, it's about the people that make the code work", @zeu.dev sharing the ATProto parts of npmx at #Atmosphereconf

Used a large refactor to make validation reports in the Starlight Links Validator plugin more user-friendly and actionable: - source locations for issues - invalid links point to the source - error messages link to docs with explanations and suggested fixes

Look what landed in DevTools in Chrome Canary! A Request # column, allowing you to: - More easily return to the page load sort order - More quickly identify when important resources are loaded late (LCP resource as request number 59? No thank you!) Thanks to Helmut Januschka for implementing!!

CSS `light-dark()` is about to support images! www.bram.us/2026/03/19/m... Shipping in Firefox 150. Starting tomorrow, available behind a flag in Chromium 148.

Added bot detection to CI after @socket.dev reported an agent that landed many PRs in major OSS projects (including Clack) Trust and Safety teams likely already detect this—hope platforms start to surface this signal to end users so we can make informed decisions and minimize a new attack surface

All my Starlight plugins, themes, and Astro integrations are now updated for this new version and Astro v6 🚀

Time to update! 🌟 And if you're using any of my plugins or themes, updates are being worked on as we speak, so stay tuned.

OK, not the *main* story of the day... but, the v6 major upgrade guide was a BIG part of Team Docs life for months. A lot of us worked on it. I hope it works for you when you upgrade! (And if it doesn't... well, that's just an opportunity to contribute yourself!) docs.astro.build/en/guides/up...

Starting with Chrome 145, DevTools now lets you throttle specific requests instead of the whole page. It’s the ideal way to test how your app handles a single slow asset or API call → goo.gle/4aP1Tcc

Open UI has been working on speccing out the focusgroup attribute: a declarative way to support roving focus & add keyboard nav to composite widgets like toolbars/menus We'd love your feedback! Learn more & see open questions: developer.chrome.com/blog/focusgr... H/t to Edge folks for prototyping

Blink: Intent to Ship: CSS contrast-color()

Firefox will start supporting `ariaNotify` in release 150. 🎉 `ariaNotify` allows you to provide text that should be announced by a screen reader if available and activated. No more fiddling with live regions. No more fiddling with live regions! 💪 Ticket: bugzilla.mozilla.org/show_bug.cgi...

CSS shape() landed in Firefox 148. It's similar to path(), but allows the full expressiveness of CSS…

🎨 As we're getting closer to the release of Astro v6, let's take a trip down memory lane with a new Starlight theme which is heavily inspired by the timeless design of the legacy Astro documentation. github.com/HiDeoo/starl...

New update for pull requests. 🚀 You can now follow the discussion directly in the "Files changed" tab. No more context switching. Plus, we streamlined change requests: If you’ve already commented, skip the summary and just submit. Get the details. ⬇️

Blink: Intent to Prototype: Speculative load measurement

🎉 Live from the CSS WG F2F: We just agreed to support multiple borders and outlines per element, comma-separated! But we can’t decide on the order: inside out or outside in? What feels more natural to you, A or B? (it needs to be the same across borders and outlines or different box-sizing values)

So there's a new meta element arriving in town (Chrome Canary first)? 👏 www.joshtumath.uk/posts/2026-0...

My book, Accessibility For Everyone, is now free and online as a website. accessibilityforeveryone.site The book was first published by A Book Apart in 2017 but it holds up! It covers web accessibility for designers, developers, content folks, and really everyone who works in tech.

Today the Temporal proposal has entered the stable stream shipping Chrome 144. This opens the gates for attaining Stage 4 at TC39. That means tonight I will be purchasing a supply of champagne in preparation. It’s been a long journey and so very worthwhile!

What a year it has been! Such a great review 🥳

📜 The Starlight Changelogs plugin now supports changelog files using the Keep a Changelog format. github.com/HiDeoo/starl...

🤯 What did I just read? Is that an ad disguised as a GitHub comment on a discussion, generated by AI? This gotta be a new low point ...

This video is such a monumental step backwards. 😅

Design Tokens excitement!! Figma finally supports variable exports help.figma.com/hc/en-us/art... DTCG published a full spec for resolvers which enables GitHub-style theme inheritance www.designtokens.org/tr/2025.10/r...

I feel the dilemma is, that I feel responsible for being friendly and welcoming to make the experience nicer for newcomers to OSS, who may not yet know the manner well. But with AI messing this up, it's really hard to tell if it's a human behind I should take care or just AI doing terrible work.

It's merged! The next alpha/beta release @astro.build will support @vite.dev Environment APIs! It took a long time because we had to re-architect the whole rendering pipeline. With this, even the @cloudflare.social Vite Plugin will work out of the box!

🌟 Starlight 0.37 is now available with a bunch of bug fixes and improvements! Check out the full release notes: github.com/withastro/st...
