Ah yes one of these days
A screenshot of GitHub Desktop dialog window "Create a Branch". In "Name" field "wmaj/fuuuuuuck" was provided, and that field has an error message next to it: "A branch named wmaj/fuuuuuuck" already exists."

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> ); } // 625 bytes after compilation import { useState } from 'react'; export default function ColorProvider({ children }) { const [color, setColor] = useState('red'); function changeColor() { setColor('blue'); } const value = { changeColor }; return ( <Button value={value}> {children} </Button> ); }

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.

🚨 BREAKING: @vite.dev downloads are DOWN over 15% since last week. 📉
Is this the beginning of the end for the most popular bundler? 🤔
npm trends chart showing vite steadily growing over the last 2 years only to swiftly jump from ~30M dls/week to ~150M dls/week, followed by a 15% decline to around ~130M dls/week.

I'm having *such* a hard time believing this chart. You people live like this?
npm trends chart screenshot showing jest package steadily growing in dls/week over the last 5 years, and vitest package increasingly growing, yet reaching about a half of jest's dls/week.

POV: You're a GitHub Copilot Agent running @biomejs.dev for the first time. 🤣
A screenshot from GitHub Copilot Agent session where AI, after linting the project, comments: "That was suspiciously fast, but I'll trust the files were actually linted. Let me check the test status and understand the structure of the pages that need the reordering feature:"

Savage! Although I've battle-tested every styling solution out there and liked tailwind the least. They'll have at least one person using that feature 😁

HUGE update to @testing-library/jest-dom - v6.7.0 drops dependency on chalk and lodash, resulting in almost 3x install size reduction!

Migrated my last dual CJS/ESM packages to pure ESM today. I'm officially CJS free, for good.

Setup’s simpler, builds are faster, packages are lighter. Everyone wins 🥰

Yet another reminder accessibility is for everyone. I love this infographic 👇🏻
Alt text: A chart titled "Inclusive – A Microsoft Design Toolkit" showing examples of impairments across four interaction categories: Touch, See, Hear, and Speak. Each category has three types of limitations: Permanent, Temporary, and Situational. Touch: Permanent: One arm Temporary: Arm injury Situational: New parent (holding baby) See: Permanent: Blind Temporary: Cataract Situational: Distracted driver Hear: Permanent: Deaf Temporary: Ear infection Situational: Bartender (noisy environment) Speak: Permanent: Non-verbal Temporary: Laryngitis Situational: Heavy accent Each cell contains a simple line drawing representing the described person or scenario.
