What are some advanced features of Vuelidate in Vue.js?

Vuelidate offers several advanced features like custom validators, asynchronous validation, and nested validations. Would you like to know more about any specific feature?

Can you explain how to create custom validators?

Sure! To create a custom validator in Vuelidate, you define a function that returns a boolean value. You can then use this function in your validation rules. Would you like a code example?

Yes, please provide a code example.

Here's a simple example:

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

const customValidator = value => value === 'custom';

export default {
  validations: {
    myField: {
      required,
      customValidator
    }
  }
};

This checks if the field is not empty and equals 'custom'. Let me know if you need further clarification!

What about asynchronous validation?

Asynchronous validation in Vuelidate can be done using a promise-based function. You can return a promise that resolves to true or false based on your validation logic. Would you like to see an example?
