How do I use the Composition API with async setup in Vue.js?

You can use the Composition API's setup function to handle asynchronous operations. Just return a promise from setup.

Can you show me a code example of that?

Sure! Here's a simple example:

import { ref } from 'vue';

export default {
  async setup() {
    const data = ref(null);
    data.value = await fetchData();
    return { data };
  }
};

async function fetchData() {
  const response = await fetch('https://api.example.com/data');
  return response.json();
}

What if I need to handle errors during the fetch?

You can use a try-catch block within the async setup function to handle errors gracefully.

Thanks! Is there a way to use multiple async calls?

Yes, you can use Promise.all to handle multiple async calls in parallel within the setup function.
