#CSSinJS
StyleXをベースにshadcn/uiをCSS-in-JS環境へ移植した便利なライブラリっぽい
Tailwindを使わずに同じようなコンポーネント設計ができて試したい

O que será que é mais performático?

- CssInJS
- CSS "puro"
- SASS Compilado (CSS)
- Tailwind

Queria ver algum benchmark entre eles, embora acredite que seja difícil comparar porque o Tailwind tem "tree-shaking" nativo, o que deixa ele meio apelão

Vou fazer esse benchmark

Meu palpite é que CSS, Tailwind e SASS vão da na mesma e CSSinJS vai tomar pau

This week I saw a team show off their storybook version of govuk react that wasn't this one. When I asked why they were rolling their own they said this hasn't been touched for two years. Is this dead because departments are all rolling their own or did the team overlook something that is public?

JS lets you call functions with backticks! 🤯

subscribe`Status: ${true}!`; // tagged template 🏷️

Used in styled-components to write CSS in JS 🎨

const Btn = styled.button`
background: ${p => p.primary ? "blue" : "gray"};

And then or course comes the point of "Oh, we need these for the second brand here. Let's just change the font family and make it a bit bigger."
Answer in CSS: "Three declarations in the :root selector"
Answer because of CSSinJS: "Oh, that's a project of three months. Need to change all components."

いまはCSSinJS採用してるからいつかはCSSフレームワークをリプレースしなきゃいけないんだけど、Tailwindが好きじゃないのでパッと良い案が思い浮かばない。まあ(ウチでも採用してる)MUIがどう出るかに合わせていく選択にするか? MUIも捨ててくっていうのも長期的にはあるかもだけど

Freshを触っているけど、PreactベースでかつDenoなのでCSSinJSなどが対応していなくて、ピュアなCSSを書きにくい・・・
talwindcssに対応したからそれを使えばいいんだろうけどCSSの勉強もしたいから生で書きたかった。VueやSvelteのコンポーネントに閉じてCSSかけるのがいかに開発体験がいいかがわかる。

@oleg008 @thecristen per your bio, seems rational to assume you're a fan of cssinjs (and also the creator). i don't view css and js as the same kind of thing - more js is inevitable as an application grows, more css isn't. systems for managing growth are good but i try to avoid it in the first (...)
