MDX with JSX

# My Component

<MyComponent prop="value">Content</MyComponent>

This is **markdown** content.

How does the MDX Formatter work?

Prettier interprets the Markdown and JSX segments simultaneously, building an AST that understands both syntaxes. Lists, tables, headings, and blockquotes are formatted alongside JSX attributes and children.

If tags are unclosed or attributes are malformed, the parser surfaces helpful messages so you can resolve issues before they reach production.

What is MDX?

MDX blends Markdown with JSX so you can embed live components inside rich content. It powers documentation sites built with frameworks like Next.js, Gatsby, and Remix.

The hybrid nature is powerful but quickly becomes messy. Proper formatting keeps engineers and content creators aligned on the same source files.

Professional usage tips

Format component catalog entries and design system documentation so written guidance and live demos appear cohesive.

Run MDX blog posts, tutorials, or release notes through the tool before committing them to keep diffs tidy and reviews fast.

Frequently Asked Questions

Will TypeScript types inside JSX still work?

Yes. The MDX parser understands TSX-style syntax, so type annotations are preserved while spacing is normalized.

Does the formatter modify frontmatter?

Frontmatter is preserved exactly as written. The formatter focuses on the MDX body and embedded JSX so metadata remains untouched.
