Getting Started

yarn add vee-validate

# Install with npm

Vue version support

The main v4 version supports Vue 3.x only, for previous versions of Vue, check the following the table

vue Version vee-validate version Documentation Link
2.x 2.x or 3.x v2 or v3
3.x 4.x v4

Usage

vee-validate offers two styles to integrate form validation into your Vue.js apps.

Composition API

The fastest way to create a form and manage its validation, behavior, and values is with the composition API.

Create your form with useForm and then use defineInputBinds to create your fields bindings and handleSubmit to use the values and send them to an API.

<script setup>
import { useForm } from 'vee-validate';

// Validation, or use `yup` or `zod`
function required(value) {
  return value ? true : 'This field is required';
}

// Create the form
const { defineInputBinds, handleSubmit, errors } = useForm({
  validationSchema: {
    field: required,
  },
});

// Define fields
const field = defineInputBinds('field');

// Submit handler
const onSubmit = handleSubmit(values => {
  // Submit to API
  console.log(values);
});
</script>

<template>
  <form @submit="onSubmit">
    <input v-bind="field" />
    <span>{{ errors.field }}</span>

    <button>Submit</button>
  </form>
</template>

You can do so much more than this, for more info check the composition API documentation.

Declarative Components

Higher-order components can also be used to build forms. Register the Field and Form components and create a simple required validator:

<script setup>
import { Field, Form } from 'vee-validate';

// Validation, or use `yup` or `zod`
function required(value) {
  return value ? true : 'This field is required';
}

// Submit handler
function onSubmit(values) {
  // Submit to API
  console.log(values);
}
</script>

<template>
  <Form v-slot="{ errors }" @submit="onSubmit">
    <Field name="field" :rules="required" />

    <span>{{ errors.field }}</span>

    <button>Submit</button>
  </Form>
</template>

The Field component renders an input of type text by default but you can control that
