Simple Vue.js Input Validation Plugin – Vee-Validate


vee-validate is a lightweight plugin for Vue.js that allows you to validate input fields, and display errors.

Easy, fast, flexible, progressive enhancement, and multiple languages. Compatible with Vue 3 and Vue 2.

Basic Usage

1. Import and register the Field and Form components.

import { Field, Form } from 'vee-validate';
export default {
  components: {
  // ...

2. Apply a basic Require validator to a form field.

<Form v-slot="{ errors }">
  <Field name="field" :rules="isRequired" />
  <span>{{ errors.field }}</span>
export default {
  components: {
  methods: {
    isRequired(value) {
      return value ? true : 'This field is required';

3. You can also use the following composition functions to validate the form.

import { useField } from 'vee-validate';
export default {
  setup() {
    function isRequired(value) {
      if (value && value.trim()) {
        return true;
      return 'This is required';
    const { errorMessage, value } = useField('fieldName', isRequired);
    return {
    <input v-model="value" type="text" />
    <span>{{ errorMessage }}</span>
// form-level validation
import { useForm, useField } from 'vee-validate';
export default {
  setup() {
    // Define a validation schema
    const simpleSchema = {
      email(value) {
        // validate email value and return messages...
      name(value) {
        // validate name value and return messages...
    // Create a form context with the validation schema
      validationSchema: simpleSchema,
    // No need to define rules for fields
    const { value: email, errorMessage: emailError } = useField('email');
    const { value: password, errorMessage: passwordError } = useField('password');
    return {
    <input name="email" v-model="email" />
    <span>{{ emailError }}</span>
    <input name="password" v-model="password" type="password" />
    <span>{{ passwordError }}</span>
