What is the Composition API in Vue 3 with TypeScript?

Can you explain the Composition API in Vue 3 and how to use it with TypeScript?

Sure! The Composition API is a new way to organize and reuse logic in Vue 3. It allows you to define reactive state and methods in a more flexible manner, especially when using TypeScript.

What are the main benefits of using the Composition API over the Options API?

The main benefits include better code organization, improved type inference with TypeScript, and easier logic reuse across components.

Can you show me a simple example of using the Composition API with TypeScript?

Absolutely! Here's a basic example:

import { ref } from 'vue';

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

This defines a reactive count variable and an increment method.

How does TypeScript enhance the development experience with the Composition API?

TypeScript provides type safety, which helps catch errors at compile time, and offers better autocompletion and documentation in IDEs, making development smoother.
