## What it is
Vuelidate is a lightweight, model-based validation library for Vue.js 2.x and 3, where validation rules are defined alongside the data model. It is now in LTS mode, with the maintainers recommending alternatives like Regle or Vee-Validate for new projects.

## Use cases
- validate form inputs in a Vue.js app
- model-based validation rules next to my Vue data
- required and email field validation in Vue 3
- validate nested form state in Vue 2
- lightweight headless form validation for Vue

## When to choose
- you are maintaining an existing Vue 2 or Vue 3 project already using Vuelidate
- you want simple, lightweight model-based validation without heavy dependencies
- you prefer validation rules defined declaratively next to your data model

## When to avoid
- you are starting a new Vue project and want actively maintained tooling
- you need strong TypeScript support or schema library integration (Zod, Valibot)
- you want Nuxt integration or a batteries-included form framework

- artifact type: library
