  "body": "## 概觀\n\n`@unifast/react` 會將 unifast 的 HAST（HTML Abstract Syntax Tree）輸出轉換為 React 元素。它提供兩個主要的函式：\n\n- [`compileToReact()`](/docs/packages/react/compile-to-react) - 高階 API：編譯 Markdown/MDX 並直接回傳 React 元素\n- [`hastToReact()`](/docs/packages/react/hast-to-react) - 低階 API：將 HAST 樹轉換為 React 元素\n\n本套件會自動處理 HTML 屬性與 React prop 名稱的對應（例如將 `class` 轉為 `className`、`for` 轉為 `htmlFor` 等），並解析 CSS style 字串。\n\n## 安裝\n\n對等相依套件：使用 `compileToReact` 時需要 `@unifast/node`。\n\n## 型別定義\n\n### CompileToReactOptions\n\n繼承 `CompileOptions`，並加入 React 專屬欄位。\n\n| 屬性 | 型別 | 說明 |\n|----------|------|-------------|\n| `createElement` | `CreateElement` | React 的 `createElement` 函式 |\n| `Fragment` | `unknown` | React 的 `Fragment` 元件 |\n| `components?` | `ComponentMap` | HTML 標籤名稱到 React 元件的對應表 |\n| *(所有 CompileOptions)* | - | 繼承自 `CompileOptions` |\n\n### CompileToReactResult\n\n| 屬性 | 型別 | 說明 |\n|----------|------|-------------|\n| `element` | `unknown` | 根 React 元素 |\n| `frontmatter` | `Record<string, unknown>` | 已解析的 frontmatter 後設資料 |\n| `diagnostics` | `Diagnostic[]` | 警告與錯誤 |\n| `stats` | `{ parseMs, transformMs, emitMs }` | 各階段耗時（毫秒） |\n| `toc` | `TocEntry[]` | 擷取而得的目錄 |\n\n### HastToReactOptions\n\n| 屬性 | 型別 | 說明 |\n|----------|------|-------------|\n| `createElement` | `CreateElement` | React 的 `createElement` 函式 |\n| `Fragment` | `unknown` | React 的 `Fragment` 元件 |\n| `components?` | `ComponentMap` | HTML 標籤名稱到自訂 React 元件的對應表 |\n\n### CreateElement\n\n```ts\ntype CreateElement = (type: any, props: any, ...children: any[]) => any;\n```\n\n### ComponentMap\n\n```ts\ntype ComponentMap = Record<string, unknown>;\n```\n\n### 屬性名稱轉換\n\n| HTML 屬性 | React Prop |\n|---------------|------------|\n| `class` | `className` |\n| `for` | `htmlFor` |\n| `accesskey` | `accessKey` |\n| `autocomplete` | `autoComplete` |\n| `autofocus` | `autoFocus` |\n| `autoplay` | `autoPlay` |\n| `charset` | `charSet` |\n| `colspan` | `colSpan` |\n| `contenteditable` | `contentEditable` |\n| `crossorigin` | `crossOrigin` |\n| `datetime` | `dateTime` |\n| `enctype` | `encType` |\n| `formaction` | `formAction` |\n| `hreflang` | `hrefLang` |\n| `httpequiv` | `httpEquiv` |\n| `inputmode` | `inputMode` |\n| `maxlength` | `maxLength` |\n| `minlength` | `minLength` |\n| `novalidate` | `noValidate` |\n| `readonly` | `readOnly` |\n| `referrerpolicy` | `referrerPolicy` |\n| `rowspan` | `rowSpan` |\n| `spellcheck` | `spellCheck` |\n| `srcdoc` | `srcDoc` |\n| `srclang` | `srcLang` |\n| `srcset` | `srcSet` |\n| `tabindex` | `tabIndex` |\n| `usemap` | `useMap` |\n\nCSS `style` 字串會自動解析為 React style 物件（例如 `\"font-size: 16px\"` 會變成 `{ fontSize: \"16px\" }`）。\n\n## 匯出列表\n\n| 匯出名稱 | 類別 | 說明 |\n|--------|------|-------------|\n| `compileToReact` | function | 將 Markdown/MDX 編譯為 React 元素 |\n| `hastToReact` | function | 將 HAST 轉換為 React 元素 |\n| `CompileToReactOptions` | type | `compileToReact` 的選項 |\n| `CompileToReactResult` | type | `compileToReact` 的結果 |\n| `HastToReactOptions` | type | `hastToReact` 的選項 |\n| `CreateElement` | type | React createElement 函式簽名 |\n| `ComponentMap` | type | HTML 標籤至元件的對應表 |",
