Babel Plugin: TypeScript to PropTypes

babel-plugin-typescript-to-proptypes is a Babel plugin designed to automatically generate React PropTypes from TypeScript interfaces and type aliases within your React components. This tool is particularly useful for projects that want to leverage TypeScript for type safety during development while still providing runtime PropTypes for environments that rely on them (e.g., older React versions, certain testing setups, or for debugging purposes). The current stable version is 2.1.0, and it maintains an active release cadence with frequent updates for Babel and TypeScript compatibility. A key differentiator is that it operates solely on the Babel AST, meaning it does not run TypeScript's type checker and therefore cannot resolve type information referenced from external files. It integrates directly into your Babel build pipeline.
