  "body": "MDX lets you use JSX expressions and import statements inside Markdown. unifast compiles MDX to JavaScript modules that can be rendered with React or other JSX runtimes.\n\n### Installation\n\n### Basic Usage\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### How MDX Works\n\nMDX extends Markdown with two capabilities:\n\n1. **JSX expressions** - Use components inline with your content.\n2. **ESM imports/exports** - Import components and export metadata.\n\nThe compiler processes MDX in these steps:\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\nThe output is a JavaScript module with a default export function that accepts a `components` prop for component injection.\n\n### Using with 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 in MDX\n\nCombine MDX with the frontmatter plugin to extract metadata:\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### See Also\n\n- [compile()](/docs/packages/node/compile) - Full API reference\n- [React Integration](/docs/guides/react) - Rendering MDX with React",
