How can I use the Composition API with TypeScript in Vue.js?

To use the Composition API with TypeScript in Vue.js, you need to define your component using the setup function. You can type your props and return values for better type safety.

Can you show me a simple example?

Sure! Here's a basic example:

import { defineComponent, ref } from 'vue';

export default defineComponent({
  setup() {
    const count = ref(0);
    const increment = () => count.value++;
    return { count, increment };
  }
});

What are the benefits of using TypeScript with Vue's Composition API?

Using TypeScript with the Composition API provides better type inference, improved IDE support, and helps catch errors at compile time, making your code more robust.
