| `2.x` | `2.x` or `3.x` | [v2](https://vee-validate.logaretm.com/v2) or [v3](https://vee-validate.logaretm.com/v3) |
| `3.x` | `4.x` | [v4](https://vee-validate.logaretm.com/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 `defineField` to create your field model and props/attributes and `handleSubmit` to use the values and send them to an API.
```vue
<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](https://vee-validate.logaretm.com/v4/guide/composition-api/getting-started/).
#### Declarative Components
Higher-order components can also be used to build forms. Register the `Field` and `Form` components and create a simple `required` validator:
```vue
<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](https://vee-validate.logaretm.com/v4/api/field#rendering-fields)
