The @types/react package provides TypeScript definitions for the popular React JavaScript library, enabling developers to leverage static typing and enhance code maintainability when working with React in TypeScript projects. Comparing versions 18.3.20 and 18.3.21 reveals subtle but potentially relevant changes. Both versions share the same dependencies: csstype for CSS property definitions and @types/prop-types for React's PropTypes system, ensuring compatibility with common styling and prop validation approaches. Furthermore, they both utilize the MIT license and are sourced from the DefinitelyTyped repository on GitHub, reflecting a consistent commitment to open-source principles and community-driven development.
A key differentiator lies in the releaseDate. Version 18.3.21 was released on May 6, 2025, whereas version 18.3.20 was released on March 24, 2025, indicating a more recent update. The unpackedSize also sees a slight increase of 2 bytes from 439971 to 439973 in the newer version. While seemingly insignificant, this increment could encompass bug fixes, performance enhancements, or minor type definition adjustments improving developer experience. Developers should consult the changelog associated with version 18.3.21 for detailed insights into the specific modifications implemented, particularly noting any fixes or updated definitions impacting their projects. The file count, which remained the same, indicates that the number of files hasn't changed, but the updated types might impact specific react features.
