🎉 Excited to announce that I'm joining VoidZero as DevRel!
As I was following the project from early on, I couldn't say no to the chance when @evanyou.me reached out.
I can't wait to share all the incredible things lined up for @rolldown.rs, OXC, @vite.dev, and @vitest.dev 👀

What stops you from using @vitest.dev browser mode? 👀
Tests.
Vitest's browser mode is stable since Vitest 4.0.
Now you can be sure that your tests pass in an *actual* browser environment.

And poof, the package.json got a lot lighter.
You don't need these Rollup plugins anymore. @rolldown.rs makes them obsolete.
Built-in support for:
◆ @rollup/plugin-node-resolve

◆ @rollup/plugin-commonjs

Rolldown can panic sometimes... but we make sure you never have to!
It's rare, but when it happens, you won't be staring at a cryptic stack trace. @rolldown.rs straight up tells you it is not your code. And a link to report it so we can fix it fast.
Good error messages => good DX

Every test suite eventually categorizes tests: "skip this in CI," "this one is flaky," "that one needs more time." and so on.
Vitest 4.1 (in beta right now) introduces Test Tags: You can now define these categories globally, attach config or behavior and eventually filter what runs.

Great that @rolldown.rs now has optimized lazy barrel handling. Even though you shouldn't use barrel files in your app, sometimes they are hard to avoid.
Time to let your bundler handle a lot of the downsides for you and still have speedy build times.

🚀 Lazy Barrel Optimization in Rolldown
Barrel files, files that re-export from other modules, are common in modern JavaScript projects but a nightmare for your build time.
Rolldown now has Lazy Barrel Optimization to fix this.
Here's how it works 🧵

But as I did when starting @vitest.dev with @antfu.me, for this new community adventure, as project steward of @npmx.dev together with @danielroe.dev, I'll be going independent. Here we go again ❤️

I wanna say this out loud. A few months ago, I told Evan that @voidzero.dev should stop sponsoring me. I burned out, and I couldn't help Vite as before. But they decided to continue supporting me while I was down. And by doing so, they helped me get back on my feet sooner. Thank y'all ❤️
Just doubled @voidzero.dev 's sponsorship to @patak.dev to $2k/mo. Excited to have you back, and proud to be supporting your work of improving the JS ecosystem.

New in @rolldown.rs - The `codeSplitting` option
We've unified code splitting configuration under a single option, deprecating both `advancedChunks` and `inlineDynamicImports`.
Migration is straightforward: the config object shape stays the same, just the name changes.

The feature was available beforehand but is now enabled by default!
