When working with APIs, errors can happen for many reasons — no internet connection, server issues, wrong URLs, or invalid data.
If errors are not handled properly, your application may crash or show confusing behavior to users.
Learning how to handle API errors helps you build stable, user-friendly, and professional web applications.
Common API Errors
- Network connection problems
- Server not responding
- Invalid API URL
- Unauthorized access
- Wrong data format
Handling these errors correctly improves both user experience and debugging.
Here, the code checks whether the server response is successful.
If not, it throws an error that is handled in the catch() block.
Using try...catch makes error handling clearer when working with async and await.
It allows you to control what happens when something goes wrong.
These examples show how API errors can be handled safely and clearly.
By mastering API error handling, students gain the ability to build reliable, professional applications that behave well even when things go wrong.
