How can I debug fetch errors in my React app?

To debug fetch errors in React, start by checking the network tab in your browser's developer tools.

What specific errors should I look for in the network tab?

Look for status codes like 404 (Not Found) or 500 (Server Error) and check the response body for error messages.

How can I handle these errors in my code?

You can use a try-catch block around your fetch call and set an error state to display an error message in your UI.

Can you show me an example of that?

Sure! Here's a simple example:

async function fetchData() {
  try {
    const response = await fetch('your-api-url');
    if (!response.ok) {
      throw new Error('Network response was not ok');
    }
    const data = await response.json();
    // handle data
  } catch (error) {
    console.error('Fetch error:', error);
    // set error state
  }
}
