How can I implement async validations in Vuelidate?

To implement async validations in Vuelidate, you can use a custom validator that returns a promise. This allows you to check conditions like server responses.

Can you show me a code example?

Sure! Here's a simple example:

import { required, minLength } from 'vuelidate/lib/validators';

const asyncValidator = (value) => {
  return new Promise((resolve) => {
    setTimeout(() => {
      if (value === 'valid') {
        resolve(true);
      } else {
        resolve(false);
      }
    }, 1000);
  });
};

export default {
  validations: {
    myField: {
      required,
      async: asyncValidator
    }
  }
};

What if I need to validate multiple fields asynchronously?

You can create multiple async validators and combine them in your validations object. Just ensure each returns a promise.
