how to handle error in react native

Question

With the help of code, can you explain how to handle errors in react native?

Answer 1

Handling errors in React Native can be made easier by following these best practices:

Global Error Handling: Use ErrorBoundary to catch JavaScript errors in your component tree, allowing your app to recover gracefully rather than crash. For native code errors (from iOS or Android), integrate libraries like react-native-exception-handler to catch and manage these issues​.

Graceful Degradation: Instead of crashing when an error occurs, consider implementing fallback UIs that keep the app usable. For example, display a retry button or a simple error message when an API call fails. This prevents disruptions to the user experience​.

User Feedback: Clearly communicate errors to users with helpful messages and provide a mechanism for them to report errors. This makes the app more user-friendly and aids in debugging​.

Automated Testing: Implement unit, integration, and end-to-end tests to catch errors early in development. Tools like UXCam can help track and analyze real-world errors​.

By using these strategies, you can create a resilient React Native app that handles errors effectively and improves user experience.
