React Coding Challenges: API Integration Challenges

Build a Weather Info Component

Create a React component that fetches weather data from a public API and displays temperature, humidity, and conditions.

Expected output: A component showing weather details with loading and error messages handled.

Hint: Use useEffect for fetching and manage loading and error states with useState.

Implement Retry Logic on API Failure

Enhance the UserList component to retry fetching data up to 3 times if the initial fetch fails.

Expected output: Component retries fetching on failure and shows error after 3 unsuccessful attempts.

Hint: Use a counter state and recursive fetch calls or loops inside useEffect.

You typically use the useEffect hook to perform API calls after the component mounts, combined with useState to manage the fetched data, loading, and error states.

Common pitfalls include not handling loading and error states, causing infinite loops in useEffect, and updating state after the component has unmounted.

You can optimize by caching responses, debouncing requests, avoiding unnecessary re-fetches with proper dependency arrays, and using memoization techniques.
