Debugging API Calls in React


Calling APIs in React apps can cause unexpected behaviors if not handled properly.


Common Pitfalls


  • Infinite loops due to missing dependency arrays.
  • Unmounted component state updates.

    • Best Practice


    useEffect(() => {
  let ignore = false;

  axios.get('/api/data').then(res => {
    if (!ignore) setData(res.data);
  });

  return () => { ignore = true; };
}, []);

    Tips


  • Always handle cleanup in async operations.
  • Use dev tools like React Query or Axios interceptors for monitoring.

    • Conclusion


    Clean API handling results in fewer bugs and better user experience.
