I’ve never considered myself a huge pnpm fan, so maybe this means even more coming from me: this is an EXCELLENT pnpm update. 🚀
Update it if you use it, start using it if you don't.

I'm exploring React Compiler to understand it better and minimize its impact on bundle size. 🕵️♀️ How about 100 bytes saved by simply declaring a variable? That can surely add up!
![// 725 bytes after compilation
import { useState } from 'react';
export default function ColorProvider({ children }) {
const [color, setColor] = useState('red');
function changeColor() {
setColor('blue');
}
return (
<Button value={{ changeColor }}>
{children}
</Button>
);
}](https://cdn.bsky.app/img/feed_thumbnail/plain/did:plc:jthwx55n5kgyekhpaqajzuhw/bafkreiexvqkidgvmjyfexldsglyn7siiblbjqjvwayawskpaxkl56k3t4i@jpeg)

👉 This VSCode/Cursor extension by blazejkustra changed EVERYTHING for me!
It adds an emoji (✨/🚫) indicating whether the component can be optimized with React Compiler or not. Updates real time as you type! 🤯

👁️ Conspiracy theory: The React team keeps making React heavier with every release to boost demand for RSC, pushing devs toward server infra... All to drive up Vercel sales. 🕵️♂️💸

React 19.2 is 12% bigger than 19.1.
And 60% bigger than 18.3.
And 136% bigger than 17.0.
I'm so tired of this.

I'm enabling OICD trusted publishing in all my npm packages. What a terrible DX 🫠 Not only I needed to click through the options manually in THIRTY NINE packages, but also got rate-limited and had to wait a full hour before I was able to continue 🤣 It's like they *didn't want* people to enable OICD!

in light of the current supply chain attacks, I've just published a @github.com action to detect packages that _lose_ their provenance.

I’ve been holding back on this for a while… but Bun v1.2.22 adding its own tsconfig flag finally pushed me over the edge. 🥴

Interesting how so many projects are now improving docs & error messages "so LLMs can understand." 🤖
