Version 1.2.0 of use-isomorphic-layout-effect brings several notable updates for React developers. The core functionality remains the same: providing a React hook that intelligently chooses between useLayoutEffect and useEffect to prevent errors during server-side rendering. However, the key improvement lies in its updated compatibility with newer React versions. The peer dependencies now include support for React 19 (^19.0.0), ensuring seamless integration with the latest React features and improvements.
Beyond React 19 support, the development dependencies have also been significantly upgraded. This includes newer versions of TypeScript, Prettier, and Babel, bringing the project up-to-date with modern tooling standards. This leads to better code maintainability, improved type safety, and a potentially enhanced developer experience when contributing to the library or debugging issues in your own projects.
For developers considering upgrading, the crucial change is the React 19 support, allowing you to leverage the hook in the newest React environments. The upgrade in tooling ensures a more consistent and reliable development workflow, aligning the library with current best practices in the JavaScript ecosystem. Also, version 1.2.0 adds 3 more files to the package increasing the unpacked size of almost 2kb, which could mean additional features and/or improvements under the hood.
