How can I create custom validators in Vuelidate for Vue.js?

To create custom validators in Vuelidate, you can define a function that returns a validation rule. For example, you can create a validator for checking if a value is a valid email.

Can you show me an example of a custom email validator?

Sure! Here's a simple example:

const emailValidator = value => {
  const emailPattern = /^[^\s@]+@[^\s@]+\.[^\s@]+$/;
  return emailPattern.test(value) || 'Invalid email address';
};

You can then use this validator in your Vuelidate setup.

How do I integrate this validator into my Vue component?

You can integrate it by adding it to your validations object in the component. For example:

validations: {
  email: { required, email: emailValidator }
}

What if I want to add multiple custom validators?

You can simply add more validators to the validations object. Just ensure each validator function returns a boolean or an error message.
