How do I set up a global error handler in Vue 3?

To set up a global error handler in Vue 3, you can use the app.config.errorHandler method. This allows you to define a function that will handle errors globally.

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('Global error handler:', err);
};

app.mount('#app');

What kind of errors can I catch with this?

You can catch runtime errors, errors in lifecycle hooks, and errors in async components. It's a great way to log and handle unexpected issues.

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

Yes, you can modify the error handler to send error details to an external logging service like Sentry or LogRocket.
