How can I implement form validation in Vue.js?

You can use the built-in validation features of Vue.js or libraries like Vuelidate or VeeValidate.

What are the advantages of using VeeValidate over Vuelidate?

VeeValidate offers a more declarative approach and built-in support for complex validation rules.

Can you show me a simple example of using VeeValidate?

Sure! Here's a basic example:

import { required } from 'vee-validate/dist/rules';
import { extend } from 'vee-validate';

extend('required', required);

<template>
  <form @submit.prevent="submitForm">
    <input v-model="name" v-validate="'required'" />
    <span>{{ errors.first('name') }}</span>
    <button type="submit">Submit</button>
  </form>
</template>

<script>
export default {
  data() {
    return { name: '' };
  },
  methods: {
    submitForm() {
      // handle form submission
    }
  }
};
</script>

What if I want to validate multiple fields?

You can apply multiple validation rules to each field by chaining them in the v-validate directive.
