How do I define interfaces in Vue 3 with TypeScript?

In Vue 3 with TypeScript, you can define interfaces to type your component props, data, and methods. For example, you can create an interface for your component's props like this:

interface MyComponentProps {
  title: string;
  count: number;
}

Then, you can use it in your component definition.

Can you show me a complete example of a Vue 3 component using an interface?

Sure! Here's a simple example:

<template>
  <div>
    <h1>{{ title }}</h1>
    <p>Count: {{ count }}</p>
  </div>
</template>

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

interface MyComponentProps {
  title: string;
  count: number;
}

export default defineComponent({
  props: {
    title: String,
    count: Number
  } as MyComponentProps,
});
</script>
