How can I improve the performance of my custom fetch hook?

To improve the performance of your custom fetch hook, consider implementing caching, reducing unnecessary re-renders, and optimizing the fetch logic.

What caching strategies would you recommend?

You can use local storage for persistent caching, or in-memory caching for temporary data. Libraries like SWR or React Query can also help.

How do I prevent unnecessary re-renders?

Use React's useMemo and useCallback hooks to memoize values and functions, and ensure your component only re-renders when necessary.

Can you give an example of a fetch hook with caching?

Sure! Here's a simple example using useEffect and local storage to cache the fetched data.
