  "body": "O MDX permite que você use expressões JSX e statements de import dentro do Markdown. O unifast compila MDX para módulos JavaScript que podem ser renderizados com React ou outros runtimes JSX.\n\n### Instalação\n\n### Uso Básico\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### Como o MDX Funciona\n\nO MDX estende o Markdown com duas capacidades:\n\n1. **Expressões JSX** - Use componentes inline com seu conteúdo.\n2. **Imports/exports ESM** - Importe componentes e exporte metadados.\n\nO compilador processa MDX nestes passos:\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\nA saída é um módulo JavaScript com uma função de export padrão que aceita uma prop `components` para injeção de componentes.\n\n### Usando com React\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### Frontmatter no MDX\n\nCombine MDX com o plugin de frontmatter para extrair metadados:\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### Veja Também\n\n- [compile()](/docs/packages/node/compile) - Referência completa da API\n- [Integração com React](/docs/guides/react) - Renderizando MDX com React",
