How can I handle errors in Vue 3 with TypeScript?

You can handle errors in Vue 3 with TypeScript by using try-catch blocks in your methods or by utilizing Vue's errorCaptured hook.

Can you give me an example of using try-catch in a Vue component?

Sure! Here's a simple example:

<template>
  <div>{{ data }}</div>
</template>

<script lang="ts">
import { defineComponent } from 'vue';

export default defineComponent({
  data() {
    return { data: null };
  },
  async mounted() {
    try {
      this.data = await fetchData();
    } catch (error) {
      console.error('Error fetching data:', error);
    }
  }
});

What about global error handling?

For global error handling, you can use the errorHandler option in your Vue app instance. This allows you to catch errors from any component.

How do I log errors to an external service?

You can log errors to an external service by calling their API in the catch block of your error handling logic, sending the error details.
