?? Preventing Memory Leaks in React Native Applications ??

Memory leaks can degrade app performance and user experience, but with proper strategies, they can be avoided. Here's how to improve memory management in your React Native apps:

?? Tips to Prevent Memory Leaks:

1?? Proper Cleanup:

Remove event listeners, timers, and subscriptions when components unmount:

useEffect(() => {
  const subscription = someEvent.addListener(handleEvent);
  return () => subscription.remove();
}, []);
        

2?? Cancel API Requests:

Use cancellation tokens or abort controllers to avoid keeping unused requests alive:

const controller = new AbortController();
 fetch(url, { signal: controller.signal });
return () => controller.abort();
        

3?? Optimize Rendering:

• Use React.memo, useCallback, and useMemo to minimize unnecessary renders.
• Avoid passing inline functions and objects in JSX.

4?? Release Resources:

• Clear image caches and other heavy resources when no longer needed.

FastImage.clearMemoryCache();
FastImage.clearDiskCache();        

5?? Use Debugging Tools:

Tools like Flipper, LeakCanary, and Chrome DevTools can help detect and debug memory leaks effectively.

?? Pro Tip: Always test in development by simulating scenarios like frequent screen navigation to catch issues early.
