How can I handle form validation errors in Vue.js using Vuelidate?

You can handle form validation errors in Vue.js with Vuelidate by defining validations in your component and using the $error property to check for errors.

Can you show me a code example of how to set this up?

Sure! First, install Vuelidate. Then, in your component, import it and define your validations like this:

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

export default {
  validations: {
    form: {
      name: { required },
      email: { required, email }
    }
  }
};

You can then use this.$v.form.$error to check for errors.

What if I want to display error messages to the user?

You can use computed properties to create user-friendly error messages based on the validation state. For example:

computed: {
  nameErrors() {
    if (!this.$v.form.name.$pending && this.$v.form.name.$error) {
      return 'Name is required.';
    }
    return '';
  }
}

Thanks! This is really helpful.
