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 give me an example of using the errorCaptured hook?

Sure! You can define the errorCaptured hook in your component like this:

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 all components?

For global error handling, you can use Vue.config.errorHandler like this:

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

Is there a way to log these errors to an external service?

Yes, you can log errors to an external service by calling their API within the error handler, like this:

Vue.config.errorHandler = (err, vm, info) => {
  // Log to external service
  axios.post('https://your-logging-service.com/log', { error: err, info });
};
