How can I implement a global error handler in Vue 3 for logging?

To implement a global error handler in Vue 3, you can use the app.config.errorHandler method. This allows you to catch errors globally and log them.

Can you show me a code example?

Sure! Here's a simple example:

const app = createApp(App);

app.config.errorHandler = (err, vm, info) => {
  console.error('Error:', err);
  console.log('Info:', info);
};

app.mount('#app');

What if I want to send the logs to an external service?

You can modify the error handler to send logs to an external service like Sentry or LogRocket. Just replace the console.error with your logging service's API call.

Is there a way to handle different types of errors differently?

Yes, you can check the type of error in the handler and implement different logging strategies based on the error type.
