Watching @jess.sh's Vitest browser mode talk at @viteconf.org immediately made me want to build an Astro renderer. Testing isolated Astro components in real browsers is a real prize.

It took a bit of work, and still does't support Vitest 4, but I have I working package. Give it a try:

This is quite a banger feature for web perf engineers. In Chrome Canary, you can now turn on an experimental feature to throttle single requests!

chrome://flags/#devtools-individual-request-throttling

This is golden to check the performance impact of a delayed resource. 👏

We have reworked the @biomejs.dev architecture as generic as possible, so now these frameworks are supported. The new architecture will unlock:
- Angular
- Embedded formatting in JS files e.g. CSS-in-JS
- Cross boundaries lint rules

It will take a bit, but the basic bricks are there. Enjoy!
Biome v2.3 is out!

👨‍👨‍👦‍👦 Full support for @vuejs.org, @svelte.dev and @astro.build
‼️ New ignore syntax
🌬️ Tailwind v4 support
⌨️ New CLI flags and reporters

Although it’s not a core task of my role as Chrome DevRel, I took the time to build something that I needed into DevTools: debugging support for CSS `@starting-style` rules.

The feature is ready for testing in Chrome Canary.
