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 defineField to create your field model and props/attributes 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 { defineField, handleSubmit, errors } = useForm({
  validationSchema: {
    field: required,
  },
});

// Define fields
const [field, fieldProps] = defineField('field');

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

<template>
  <form @submit="onSubmit">
    <input v-model="field" v-bind="fieldProps" />
    <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
