{"version":"1.0","type":"rich","title":"Here is a useSafeState hook that ignores state changes after a component has been unmounted.","description":"This example demonstrates a React hook that prevents state updates after a component unmounts. The `useSafeState` hook wraps the standard `useState` and `useCallback` APIs, using a `useRef` flag set by `useEffect` cleanup to track unmount status. When `setValue` is called after unmounting, the `useSafeCallback` wrapper checks the ref and skips execution, avoiding React’s “Cannot update a component while rendering a different component” warning. The code shows three related hooks—`useUnmounted`, `useSafeCallback`, and `useSafeState`—together in a single TypeScript file, with no external data source or rendering logic.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-0089cda311be5face320a23531799681?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
