What are the best practices for using fetch in Vue 3?

When using fetch in Vue 3, it's important to handle errors gracefully, use async/await for cleaner code, and manage state effectively.

Can you give me an example of using fetch with async/await?

Sure! Here's a simple example:

async fetchData() {
  try {
    const response = await fetch('https://api.example.com/data');
    if (!response.ok) throw new Error('Network response was not ok');
    const data = await response.json();
    this.data = data;
  } catch (error) {
    console.error('Fetch error:', error);
  }
}

How can I manage loading states while fetching data?

You can use a loading state variable. Set it to true before the fetch call and false after it completes, like this:

this.loading = true;
await fetchData();
this.loading = false;

What about handling multiple fetch requests?

For multiple fetch requests, you can use Promise.all to handle them concurrently. Just ensure to manage the state for each request.
