Interesting project with some cool ideas, curious to see where it goes 🪴
Introducing Flint: a fast, friendly linter.
Flint is an experimental linter made to validate several hypotheses: hybrid linting, streamlined rich configuration, thorough docs & plugins, and tooling coordination.
Expect to hear more about Flint over the next month. ❤️🔥

A new milestone! @vitest.dev hit 20 million mark 🎉 Took us 4 years since the first closed 0.0.0 release on December 3d, 2021 😄

Hello friends and welcome to a new “How is ESM vs CJS going!” 33.4% of the popular packages on npm now includes ESM. Up from 29.6% half a year ago. We have a third!
ESM-only is up from 11.5% to 12.6%.
This is also the impact of half a year of Node 18 being EOL, making `require(esm)` available

Merged! Vitest 4.0.14 includes a new tabbed view and slider for visual regression reports 🎉
This feature required a lot of work under the hood, including the creation of the new test artifacts API. Really curious to see how it'll be used by us and the ecosystem 👀

Been experimenting with a type-safe, function-based, framework-agnostic form generator and it feels… weirdly nice to use?

Wrote about how our testing strategy evolved to include visual regression testing and how we can generate hundreds of tests in a handful of lines of code
Spoiler: turns out high school math can be useful after all 😶🌫️

When Manual Testing Becomes Unsustainable · Raul Macarie
At some point, checking every visual variant by hand becomes impossible. This is about that turning point, and what came after.

Potentially coming to a @vitest.dev browser mode report near you 👀
New view for visual regression testing failures with tabs for:
- diff, reference, and actual screenshots
- slider to compare reference vs actual (before/after style)

part of my resentment towards LLMs is to do with them crowding out anything else we could be talking about. there are so many things I could be reading to get better at my craft but I'm presented with "you should actually get worse at it on purpose because nothing matters any more"

Totally missed this 🙃
Proud to have helped bring visual regression testing to a tool I use daily, and even more so because it started from something I needed as a user 🙌🏼
And thanks to @erus.dev for the support along the way 💚
