react-hook-lab Adds useDeepClone Hook for Safe, Performance-Aware Deep Cloning
The react-hook-lab library has released a new deepClone utility and companion useDeepClone React hook designed to address longstanding challenges with deep cloning objects in React applications. Unlike JSON.parse/JSON.stringify, the custom cloning engine preserves complex types such as Map, Set, Date, RegExp, and TypedArrays, while also handling circular references and guarding against prototype pollution. The useDeepClone hook adds a reference-stability layer by caching the cloned result and skipping re-cloning entirely when the input reference has not changed between renders, preventing unnecessary child re-renders. The standalone deepClone utility can also be used independently inside event handlers, state transitions, or utility functions. The release additionally includes standardized code formatting, minor ESLint fixes, and refined internal JSDoc comments to improve the developer experience across the library.
