babel-plugin-react-docgen is a Babel plugin that extracts component documentation from React components using react-docgen. It automatically generates metadata from your component's code, including prop types, default values, and component descriptions, making it easier to create and maintain documentation. The plugin integrates with Babel's compilation process, enabling seamless documentation generation directly from your source code, streamlining the workflow for documenting React components, and ensuring documentation remains up-to-date with code changes.
