Vuelidate
Vuelidate is a model-based validation library for Vue.js applications. It functions as a client-side data validator and validation engine that decouples verification logic from the user interface by checking data models and state objects against defined rules.
The system tracks field interactions and marks inputs as dirty to manage when validation messages are triggered. This approach allows the library to provide real-time user input feedback and verify model integrity before data is submitted.
The framework covers form state validation, validation error rendering, and the configuration of validation behaviors. It also includes utilities for resetting validation states and verifying that data models meet specific requirements.
Features
- Vue.js Validation Libraries - A dedicated validation library built specifically for Vue.js applications to ensure input requirements are met.
- Data Validation - Verifies that data models meet specific structural and type requirements through a set of rules.
- Interaction-Based Suppression - Monitors user input to suppress validation errors until a field has been explicitly touched.
- Model-Based State Validation - Maps validation rules directly to data models to track the validity of individual properties.
- Model-Based Validation Engines - Provides a logic layer that verifies data models and state objects against constraints independently of the UI.
- Field Interaction Tracking - Implements a mechanism to track field interactions, preventing error messages from appearing until a field is touched.
- Client-Side Input Validators - Tracks field interactions and marks inputs as dirty to trigger validation messages on the frontend.
- Client-Side Input Verification - Verifies that data is correct and complete in the browser to reduce unnecessary server requests.
- Form Validation - Checks the current state of a form against defined rules to determine overall validity.
- Reactive Dependency Triggers - Uses Vue reactivity to automatically trigger validation checks whenever the underlying model data changes.
- Lazy Evaluation - Defers the execution of validation rules until specific events occur to optimize performance.
- Boolean Predicates - Determines field validity by executing a series of boolean predicate functions.
- Hook-Based Logic Encapsulations - Provides custom hooks and mixins to encapsulate validation logic and state within Vue components.
- Real-Time Input Feedback - Provides real-time error messages and visual cues to users as they interact with form fields.
- Validation Behavior Configuration - Provides a configuration system to define when validation triggers occur and how the interface responds.
- Validation Error Renderers - Provides mechanisms for rendering active validation failures and error messages directly in the UI.
- Form Handling - Listed in the “Form Handling” section of the Awesome Vue awesome list.
- Form Management - Model-based validation library for Vue.
