MDX extends standard Markdown by letting you embed JSX components directly in your content. Write headings, lists, and paragraphs in Markdown, then drop in interactive React components wherever you need them — tabs, callouts, code playgrounds, or anything else your framework supports. MDX files are compiled to JavaScript, so they work with any React-based framework including Next.js, Gatsby, and Remix. The format has become the standard for documentation sites, design systems, and content-heavy applications where authors want the simplicity of Markdown with the flexibility of components.
Why use MDX for documentation?
Documentation written in MDX stays readable as source files while producing rich, interactive output. Authors write in Markdown they already know, and engineers define reusable components for API references, configuration tables, or live code examples. Version control works naturally since MDX is plain text. Frontmatter gives you structured metadata for titles, descriptions, and navigation without a separate CMS. Because MDX compiles to React, you get type checking, component composition, and the full npm ecosystem. Teams that adopt MDX for docs find that content stays closer to the codebase, updates ship faster, and the gap between writing and publishing narrows significantly.
