# Styletron

## 매 한 줄
> **"매 atomic CSS-in-JS 의 pioneer"**. Uber 가 만든 styling library — 매 declared style 을 atomic class (`.a { color: red }`) 로 deduplicate, 매 SSR-friendly. 2026 perspective: 매 historical interest — 현재 의 mainstream 은 zero-runtime (vanilla-extract, Linaria, Panda CSS) 또는 utility (Tailwind v4).

## 매 핵심

### 매 idea
- 매 styled component 의 declared CSS 를 atomic single-property class 로 split.
- 매 동일 declaration 은 한 class 의 share → 매 small bundle.
- Runtime 의 dedupe + SSR 의 style extract.

### 매 Styletron 의 modern 위치
- 매 BaseWeb (Uber UI lib) 의 default styling engine.
- Production 사용 의 still alive 그러나 매 new project 의 default 가 아님.
- 매 atomic 의 idea 는 Tailwind / UnoCSS 가 inherit (compile-time).

### 매 modern alternatives (2026)
- **vanilla-extract**: zero-runtime, type-safe.
- **Panda CSS**: build-time atomic.
- **Tailwind CSS v4**: 매 utility-first mainstream.
- **CSS Modules + plain CSS**: 매 simplest baseline.

### 매 응용
1. BaseWeb component library 사용.
2. Legacy Uber-stack codebase 유지보수.
3. 매 historical case study (atomic CSS 의 origin).

## 💻 패턴

### Setup (React)
```typescript
import { Provider as StyletronProvider } from "styletron-react";
import { Client as Styletron } from "styletron-engine-atomic";

const engine = new Styletron();

export function App() {
  return (
    <StyletronProvider value={engine}>
      <Page />
    </StyletronProvider>
  );
}
```

### styled component
```typescript
import { styled } from "styletron-react";

const Button = styled("button", {
  backgroundColor: "blue",
  color: "white",
  padding: "8px 16px",
  borderRadius: "4px",
});

// usage: <Button>Click</Button>
```

### Dynamic prop-based styling
```typescript
const Button = styled<"button", { $primary?: boolean }>("button", ({ $primary }) => ({
  backgroundColor: $primary ? "blue" : "gray",
  color: "white",
}));
```

### useStyletron hook
```typescript
import { useStyletron } from "styletron-react";

function Card() {
  const [css] = useStyletron();
  return <div className={css({ padding: "16px", boxShadow: "0 2px 4px rgba(0,0,0,0.1)" })}>Hello</div>;
}
```

### SSR (Next.js)
```typescript
// pages/_document.tsx
import Document, { Html, Head, Main, NextScript } from "next/document";
import { Server, Sheet } from "styletron-engine-atomic";
import { Provider } from "styletron-react";

export default class MyDoc extends Document {
  static async getInitialProps(ctx) {
    const engine = new Server();
    const initialProps = await Document.getInitialProps({
      ...ctx,
      renderPage: () => ctx.renderPage({
        enhanceApp: (App) => (props) => (
          <Provider value={engine}><App {...props} /></Provider>
        ),
      }),
    });
    return { ...initialProps, stylesheets: engine.getStylesheets() };
  }
  render() {
    return (
      <Html>
        <Head>
          {this.props.stylesheets.map((s, i) => (
            <style className="_styletron_hydrate_" dangerouslySetInnerHTML={{ __html: s.css }} key={i} />
          ))}
        </Head>
        <body><Main /><NextScript /></body>
      </Html>
    );
  }
}
```

### Migration to vanilla-extract (modern)
```typescript
// styles.css.ts
import { style } from "@vanilla-extract/css";
export const button = style({
  backgroundColor: "blue",
  color: "white",
  padding: "8px 16px",
});
// Component.tsx
import { button } from "./styles.css";
<button className={button}>Click</button>
```

## 매 결정 기준
| 상황 | Approach |
|---|---|
| 매 BaseWeb 사용 codebase | Styletron (forced) |
| 매 new project (2026) | Tailwind v4 또는 vanilla-extract |
| 매 type-safe + zero-runtime | vanilla-extract |
| 매 quick prototype | Tailwind |
| 매 library 배포 (no runtime) | Linaria / Panda CSS |

**기본값**: 매 new code 는 Tailwind v4 또는 vanilla-extract. 매 Styletron 신규 채택 의 X.

## 🔗 Graph
- 부모: [[CSS_Architecture_and_Styling|CSS-in-JS]]
- 변형: [[vanilla-extract]] · [[Panda-CSS]]
- 응용: [[BaseWeb]] · [[React]]
- Adjacent: [[Tailwind CSS]] · [[Atomic-CSS]]

## 🤖 LLM 활용
**언제**: BaseWeb codebase 의 maintenance, 매 atomic CSS history 의 understand.
**언제 X**: 매 greenfield project — modern alternatives 가 superior (zero-runtime, type-safe).

## ❌ 안티패턴
- **매 new project 의 Styletron 채택**: 매 ecosystem momentum 이 vanilla-extract / Tailwind 로 이동 — 매 future-proof X.
- **Runtime dedupe overhead**: 매 large app 에서 visible — 매 build-time atomic (Panda) 이 우월.
- **Styletron + Tailwind 동시**: 매 conflicting paradigm — pick one.

## 🧪 검증 / 중복
- Verified (styletron.org, GitHub uber/styletron, Uber engineering blog 2017).
- 신뢰도 A (매 historically), 매 modern adoption 의 declining.
