How can I implement advanced validation in Vue 3 using VeeValidate?

To implement advanced validation in Vue 3 with VeeValidate, you can use the useForm and useField composables. This allows you to create complex validation rules and manage form state effectively.

Can you give me an example of custom validation rules?

Sure! You can create a custom validation rule like this:

import { defineRule } from 'vee-validate';

defineRule('customRule', value => {
  return value === 'valid'; // Example condition
});

How do I handle asynchronous validation?

For asynchronous validation, you can return a promise from your validation rule. For example:

defineRule('asyncRule', async value => {
  const response = await fetch(`/api/validate?value=${value}`);
  const result = await response.json();
  return result.isValid;
});

What about integrating VeeValidate with Vue Router?

You can integrate VeeValidate with Vue Router by using navigation guards to validate forms before navigating away. This ensures that users complete the form correctly before proceeding.
