How can I implement global error handling in Vue.js?

You can implement global error handling in Vue.js by using the errorCaptured lifecycle hook or by setting up a global error handler in your Vue instance.

Can you show me an example of using the errorCaptured hook?

Sure! You can use the errorCaptured hook in a parent component to catch errors from its child components. Here's a simple example:

export default {
  errorCaptured(err, vm, info) {
    console.error('Error captured:', err);
    return false; // Prevents the error from propagating further
  }
};

What about handling errors globally for API calls?

For API calls, you can create an Axios interceptor to handle errors globally. Here's how you can do it:

import axios from 'axios';

axios.interceptors.response.use(
  response => response,
  error => {
    console.error('API error:', error);
    return Promise.reject(error);
  }
);

Is there a way to display user-friendly error messages?

Yes! You can create a centralized error handling service that formats error messages and displays them using a notification system or a modal.
