Vite 6 adoption should accelerate now that Vitest 3 is out. Although we expect to still see some usage of Vite 4, Vite 5 was released more than a year ago, and most frameworks and tools supported it from day one. Are you still using Vite 4? Is there something preventing you from upgrading?

You mean vanity-checking stats of my OSS projects? 😂

This is showing NPM weekly downloads for a package, so that maintainers and users easily see which versions are the most popular.

Want to quickly check NPM package popularity?

✨ I've built a tiny, beautiful terminal tool to check package stats. No setup needed, just run:

$ npx pkg-stats <package>

Let me know what you think!

A lot of React Native Testing Library users are still on ver. 7, 9, and 11. These were great... like 2-4 years ago 😯

It’s time to upgrade! 🚀

TIL: default params in JS are evaluated:
✅ when the function is called
❌ not when it's defined

Why does Xcode default to putting build output (DerivedData) in ~/Library/Developer/Xcode/DerivedData by default? 🤔

Wouldn't it be way more practical to keep it in the project directory? Easier to find, clean, cache, and manage overall.

What am I missing here?

GitHub - callstack/byorg-ai: TypeScript framework for writing chatbot applications

mdjdev.bsky.social @mdjdev.bsky.social · Dec 8

I've noticed a curious thing about yarn vs pnpm:

- yarn: deleting and recreating `yarn.lock` after changing deps creates different (cleaner?) lock file
- pnpm: recreating lock files generates exactly the same file

🤔
