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

To implement custom validation in Vue 3 with VeeValidate, you can create a custom validation rule using the defineRule function.

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

Sure! Here's a simple example:

import { defineRule } from 'vee-validate';

defineRule('is-odd', value => {
  return value % 2 !== 0 || 'The number must be odd!';
});

How do I use this custom rule in my form?

You can use the custom rule in your template like this:

<Field name="number" rules="is-odd" />
<ErrorMessage name="number" />

What if I want to add multiple custom rules?

You can define multiple rules by calling defineRule for each one. Just make sure to reference them in your form fields.
