#react#hooks#data-fetching

Answer

  1. Using useEffect Hook: Implement the useEffect hook to handle side effects like data fetching when the component mounts.
    • Example: useEffect(() => { fetchData(); }, []);
  2. State Management: Utilize useState to manage loading and data state.
    • Example: const [data, setData] = useState(null); const [loading, setLoading] = useState(true);
  3. Error Handling: Implement error handling within the fetch process to capture and set error states.
  4. Cleanup: Use cleanup functions in useEffect to prevent memory leaks on component unmount.
