AWS, JavaScript, React - Deploy Web Apps on the Cloud - Dealing with Errors in Fetch API

The video tutorial addresses issues with the fetcher function when the Jason server is not running or responding. It introduces error handling using try-catch blocks to make the function more reliable. The tutorial updates the main app components to handle a new response object and demonstrates how to display error messages for both categories and products. It also refactors fetcher functions to improve URL management and prepares for handling 404 errors in the next video.

What issue arises when the JSON server is not running?

• The webpage crashes completely.

• The webpage displays outdated data.

• The webpage shows a blank space where categories should be.

• The webpage displays random data.

What does the response object in the fetcher function contain?

• Only the fetched data.

• Only the error message.

• Server status information.

• Both error message and data.

• By updating state and rendering functions.

• By removing all error handling.

What is the benefit of refactoring the code to manage URLs separately?

• It makes the code run faster.

• It increases the number of API calls.

• It reduces the need for error handling.

• It simplifies URL updates and maintenance.

What is planned for the next video regarding error handling?
