Angular hit 100k stars on GitHub :) That’s a great milestone!

Flaky tests and memory leaks are the worst. @vitest.dev now has a flag that catches uncleared intervals, lingering servers, and other async operations leaking across your tests. Available in the latest 4.1 beta. Big shout out to @ariperkkio.dev from the Vitest team for landing this PR! 🔥

Vitest 4.1 is on the horizon, but we're already looking ahead! What are your main pain points in your testing workflow right now? Let us know in the Vitest 5 discussion thread!

In the next version of Vitest you can track leaking asynchronous resources via `--detect-async-leaks` option! Available in v4.1.0-beta.4 release. 🔍 (notice missing await in the example)

Do not copy/paste AI-generated answer to a PR review comment. Use your own reasoning and understanding. It’s both disrespectful and unprofessional to the reviewer ☹️. If you can explain why that AI-solution works yourself, how do I trust you know what you are doing?

simply, more OSS projects should DO THIS. OSS is a long playing game, if not forever. but we are people behind those projects, and we need good rest and balance to keep things sustainable. I am super happy to see this move and looking forward to see how it could change how OSS works for all of us.

I just tried the package comparison in @npmx.dev to decide between two packages. Where has this been all my life?! 😍

if you are mad at on open source project, bashing it on social media doesn’t help anyone and doesn’t even boost ego that much

"I have received. Other people helped me. Now, if I'm able to help other people, that's a pleasure. [...] I hope that is a perpetuating thing." — @danielroe.dev, maintainer of @nuxt.com and @npmx.dev

Seeing how quickly @npmx.dev came onto the scene and how many developers from different backgrounds came together to build it gives me hope for the future. The real value is always the people and the culture surrounding them.

`npm isnt pnpm` is a valid command, can you guess what it does?

Excited to announce that I've officially joined @chromatic.com! My main focus will be working around features related to @vitest.dev 🤝

🧪 `@nuxt/test-utils` v4 is out 🚀 👺 mocking is much more reliable ⚡ works with vitest v4 + Vite's native Module Runner ⚗️ registerEndpoint improvements much thanks to github.com/yamachi4416 and @adamdehaven.com ❤️ 👉 github.com/nuxt/test-u... let me know how it goes! 🙏

For all your AsyncLocalStorage needs, Vitest 4.1 now supports `aroundEach` and `aroundAll` hooks! main.vitest.dev/api/hooks#ar...

It has been more than a year since I deactivated my X account. I had 12K followers there, a bit less than the good folks I found posting into the atmosphere. 5K posts are a lot. It shows how many conversations I enjoyed here. This is a good place to connect with others. A good place for adventures.

let's have some good old open source adventures y'all :)

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.

The State of JS 2025 results are out! 🏆 Most Adopted Tech → Vitest 🏆 Highest Satisfaction → Vite (98%) & Vitest (97%) 🏆 Highest Interest → Vitest (83%) & Rolldown (80%) But that's not all! A thread 🧵

we (or really the entire oss community) would not be the same without you ❤️

I loved working full-time on @vite.dev hired by StackBlitz. High praise to companies hiring OSS devs! 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 ❤️

The next @vitest.dev version has a new `test.extend` syntax that supports type inference (including the correct scope)! main.vitest.dev/guide/test-c...

Use Vitest, but don't use Vite? Vitest 4.1 introduces a new flag to disable Vite module runner entirely, but keep using all the Vitest features you like! Try it out and let us know what you think:

I tried updating grid.layoutit.com, a vue spa, from vite 2 (!) to the vite 8 beta, and everything just worked. It is incredible how stable @vite.dev has remained over the years, and even more with the massive changes they made to move to @rolldown.rs. Impressive care for the ecosystem.

I feel like a hacker every time I need to type :wq

Rolldown 1.0 RC is here 🎉 🔒 Stable API: No breaking changes planned before 1.0 ⚡ 10-30x faster than Rollup while staying compatible 🧩 Multiple chunking algorithm improvements 📦 3,400+ commits since beta: 749 features, 682 fixes, 109 perf optimizations

Good read. A submission to the European Commission's call for evidence on Towards European Open Digital Ecosystems (importance of OSS for EU tech sovereignty, security and competitiveness). It ends with: > If you work in OSS, consider adding your voice. The feedback period ends February 3, 2026.

An anonymous hacker dressed as the Pink Ranger deleted a racist website right during her talk at a security conference. This is my kind of internet culture, not crypto bros or Silicon Valley. hackread.com/white-suprem...

This @fosdem.org talk about @matrix.org history is quite relevant today. EU organizations and companies being forced to take their tech sovereignty seriously is an opportunity to adopt shared OSS solutions. But it is hard for EU programs to distribute the money to reach the right upstream hands.

This percentage figure really shows how much control EU companies have given to their US counterparts. Also, how big is the opportunity here. > 80% of total spending on cloud software and services for business use in Europe went to US companies

The Nobel Peace Prize becoming so prestigious that wars are fought over a head of state coveting it is some real monkey paw stuff for Alfred Nobel.

They finally went too far, on so many fronts. They will not be able to dig themselves out of their cruel and destructive mess. Once defeated, I hope we'll end up with more humane organizations, both at the international level and across grassroots movements that have sprung from the current fights.

Vitest 4.0.17 now shows a better diff when used with asymmetric matchers:

just a reminder that i have github sponsors if you'd like to sponsor the OSS work i do. i maintain quite a few projects, and contribute to many more. nobody other than these sponsors pay for that. so these help a huge amount, however small 🙏 thanks so much to those who already did ❤️
