vee-validate is a form validation library for Vue.js that handles validation logic while leaving UI rendering to the developer.
The library solves the problem of managing form validation state and behavior in Vue applications. It provides two integration approaches: a Composition API style using `useForm` and `defineField` for programmatic control, and a declarative component style with `Field` and `Form` components for template-based validation. The tool supports synchronous and asynchronous validation at both field and form levels, with a small footprint and minimal opinions about how forms should be rendered.
Developers should choose vee-validate if they want validation logic decoupled from UI rendering, giving them full control over form appearance while the library handles the complicated state management concerns. It works with native HTML elements or any UI library components, making it suitable for projects ranging from simple progressive enhancements to complex Vue applications. The library includes a companion package with built-in validation rules covering common scenarios, and provides localization support for those rules across many languages. The tool supports both Vue 2.x and Vue 3.x through different major versions, with separate documentation for each.
The project maintains active engagement with its community through a sponsorship program. Development activity shows consistent attention to documentation with separate guides for composition API and declarative component approaches. The tool has accumulated a substantial user base indicated by download metrics, and the maintainer actively manages contributions through a documented contribution guide.
