A Vue 3 compatible port of vee-validate v3.
This package allows developers to continue using vee-validate v3 without breaking changes while upgrading to Vue 3.

The official vee-validate v4 introduced significant breaking changes and a complete API overhaul.
If you're migrating a large codebase from Vue 2 to Vue 3 and rely on vee-validate v3, this package:

• Lets you migrate to Vue 3 without rewriting your validation logic
• Retains existing components and validation rules
• Ensures compatibility with modern Vue 3 setups

npm install vee-validate-v3-vue3

import Vue from 'vue';
import { ValidationProvider, ValidationObserver, extend } from 'vee-validate-v3-vue3';
Vue.component('ValidationProvider', ValidationProvider);
Vue.component('ValidationObserver', ValidationObserver);

import { required, email } from 'vee-validate-v3-vue3/dist/rules';
extend('required', required);
extend('email', email);

<script src="https://unpkg.com/vee-validate-v3-vue3/dist/vee-validate.min.js"></script>

You can access the components as global variables:

const { ValidationProvider, ValidationObserver } = VeeValidate;

• ✅ Vue 3.x
• ❌ Not compatible with Vue 2
• ✅ Fully backward-compatible with vee-validate v3 API

• dist/ - CJS, ESM, and UMD bundles
• dist/rules/ - Individual validation rules (same as v3)

Clone the repo and run:

npm install
npm run build

This is a community-maintained package to help developers avoid rewriting their vee-validate v3 code while adopting Vue 3.

This has worked perfectly for 10 months for me so decided to publish this as package.
