How can I create custom validation rules in Vue.js using validators?

You can create custom validation rules in Vue.js by defining a function that checks the validity of the input. You can then use this function with the Vue validators.

Can you show me an example of a custom validation rule?

Sure! Here's a simple example: you can create a rule that checks if a string is at least 5 characters long. Define a function like this:

function minLength(value) {
  return value.length >= 5;
}

Then, use it in your component.

How do I integrate this custom rule with a form in Vue?

You can integrate it by using the v-validate directive in your form input. For example:

<input v-model="inputValue" v-validate="'minLength'" />

Make sure to register the custom rule with your validator.

What if I want to add multiple validation rules?

You can combine multiple rules by separating them with a pipe. For example:

<input v-model="inputValue" v-validate="'minLength|email'" />

This will validate both the minimum length and the email format.
