Code Comparison

Before

// ❌ Bad API Call: Potential race conditions & memory leaks
const FetchComponent = ({ userId }) => {
  const [userData, setUserData] = useState(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    setLoading(true);
    fetch(`https://api.example.com/user/${userId}`)
      .then(response => response.json())
      .then(data => {
        setUserData(data);
        setLoading(false);
      });

  }, [userId]);

  return (
    <div>
      {loading ? "Loading..." : <pre>{JSON.stringify(userData, null, 2)}</pre>}
    </div>
  );
};

After

// ✅ Proper API Handling with AbortController
const FetchComponent = ({ userId }) => {
  const [userData, setUserData] = useState(null);
  const [loading, setLoading] = useState(true);

  useEffect(() => {
    const controller = new AbortController();
    const signal = controller.signal;

    setLoading(true);
    fetch(`https://api.example.com/user/${userId}`, { signal })
      .then(response => response.json())
      .then(data => {
        if (!signal.aborted) {
          setUserData(data);
          setLoading(false);
        }
      })
      .catch(error => {
        if (error.name !== "AbortError") {
          console.error("Fetch error:", error);
        }
      });

    return () => controller.abort();

  }, [userId]);

  return (
    <div>
      {loading ? "Loading..." : <pre>{JSON.stringify(userData, null, 2)}</pre>}
    </div>
  );
};
