What are the best practices for form validation in Vue.js using Vuelidate?

When using Vuelidate for form validation in Vue.js, it's essential to keep your validations organized and modular. Start by defining your validations in a separate file or within the component's data. This helps maintain clarity and reusability.

Can you give me an example of how to structure my validations?

Sure! You can structure your validations like this:

validations() {
  return {
    name: { required, minLength: minLength(3) },
    email: { required, email },
  };
}

This way, each field has its own set of rules, making it easier to manage.

How do I handle validation errors in the UI?

You can display validation errors by checking the $v object provided by Vuelidate. For example:

<span v-if="!$v.name.$pending && !$v.name.required">Name is required.</span>

Are there any performance considerations I should be aware of?

Yes, avoid excessive validations on large forms. Use lazy validation or debounce input events to improve performance.
