How can I implement async validation in Vue forms?

You can implement async validation in Vue forms by using the async and await keywords in your validation methods.

Can you give me an example of how to do that?

Sure! You can create a method that checks the validity of the input against an API. For example:

async validateEmail(email) {
  const response = await fetch(`https://api.example.com/validate-email?email=${email}`);
  const data = await response.json();
  return data.isValid;
}

What if I want to show a loading indicator while validating?

You can use a data property to track the loading state. Set it to true before the API call and false after it. Then, conditionally render a loading spinner in your template.
