  "body": "MDX 讓您可以在 Markdown 中使用 JSX 運算式與 import 語句。unifast 會將 MDX 編譯為 JavaScript 模組，可透過 React 或其他 JSX 執行環境進行渲染。\n\n### 安裝\n\n### 基本用法\n\n```ts\n\nconst source = `\n# Hello\n\nexport const meta = { title: \"My Page\" };\n`;\n\nconst result = compile(source, { inputKind: \"mdx\" });\n// result.output is a JavaScript module string\n```\n\n### MDX 運作方式\n\nMDX 為 Markdown 擴充了兩項能力：\n\n1. **JSX 運算式** - 可在內容中直接嵌入元件。\n2. **ESM import/export** - 可匯入元件並匯出後設資料。\n\n編譯器會依下列步驟處理 MDX：\n\n```\nMDX source\n  → Parse (Markdown + JSX + ESM)\n  → MdAst with JSX/ESM nodes\n  → Lower to HAst\n  → Emit as JavaScript module\n```\n\n輸出結果是一個 JavaScript 模組，其預設匯出為一個函式，該函式可接受 `components` prop 以進行元件注入。\n\n### 搭配 React 使用\n\n```ts\n\nconst source = `# Hello\\n\\nThis is **MDX**.`;\n\nconst result = compile(source, { inputKind: \"mdx\" });\nconst Component = compileToReact(result);\n\n// Render in your React app\n\n```\n\n### MDX 中的 Frontmatter\n\n將 MDX 與 frontmatter 外掛搭配使用，即可擷取後設資料：\n\n```ts\n\nconst source = `---\ntitle: My Article\nauthor: Jane\n---\n\n# {frontmatter.title}\n\nWritten by {frontmatter.author}.\n`;\n\nconst result = compile(source, {\n  inputKind: \"mdx\",\n  plugins: [frontmatter()],\n});\n\nconsole.log(result.frontmatter);\n// { title: \"My Article\", author: \"Jane\" }\n```\n\n### 另請參閱\n\n- [compile()](/docs/packages/node/compile) - 完整的 API 參考\n- [React 整合](/docs/guides/react) - 以 React 渲染 MDX",
