@formkit/validation is a validation plugin that integrates with FormKit to add real-time input validation and error handling for Vue forms. Developers use it to validate form fields against built-in or custom rules and display validation errors to users without writing boilerplate validation logic. It supports async validation, conditional rules, and works seamlessly with FormKit's form inputs and state management.
