How can I handle errors in Vue.js components?

In Vue.js, you can handle errors in components using the errorCaptured lifecycle hook or by using try-catch blocks in methods.

Can you give me an example of using errorCaptured?

Sure! You can use the errorCaptured hook like this:

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

What about global error handling?

For global error handling, you can use Vue.config.errorHandler to catch errors across all components. Here's an example:

Vue.config.errorHandler = (err, vm, info) => {
  console.error('Global error handler:', err);
};

Are there any best practices for error handling in Vue?

Yes! Some best practices include logging errors, providing user feedback, and using error boundaries to isolate errors.
