Building this integration has been amazing opportunity to dogfood all APIs we've added into @vitest.dev in past years. It's using features like new Reporter APIs, Vitest plugin hooks, browser commands, CDP, test tags and much more! Vitest is definitely one of the most extensible JS tools out there.
@vitest.dev just surpassed Jest in npm weekly downloads 📈

There's some impressive work going on with 3rd party oxc powered coverage instrumentation that can replace Babel based istanbul-lib-instrument 👀
> 8-11x faster than babel-plugin-istanbul, 13-15x faster than swc-plugin-coverage-instrument (Rust/WASM), 25-30x faster than istanbul-lib-instrument.
And it's open source! github.com/chromaui/chr...
Testing terminal output is hard. Especially in cases that involve clearing screen partially while maintaining stable log output elsewhere on screen. With ansivision it's possible to simulate what output all the ansi codes would render visually in real terminal. No need to use heavy node-pty anymore.
If you've published a package using staged publishing before this fix, all that's needed now is to re-publish the same package and @npmx.dev will display the trusted publishing label again 🤝
This day 4 years ago I sent my first PR to @vitest.dev. Back then it was on v0.7.4 with 80K weekly downloads. After one year and +70 more PRs, @antfu.me and @erus.dev invited me to join the team.
Today we are at v4.1.0 with 35M weekly downloads. Maybe in 2030 we'll have Vitest 8 with 140M downloads.

Super happy to see a fairly niche library of mine being put to good use 😍
npm now signals when a package used staged publishing! 🎉
this will fix a whole bunch of trust scales (e.g. pnpm trust downgrades)
