Validate.js
Validate.js is a JavaScript library designed for declarative data validation and form processing. It provides a framework for verifying complex objects and individual data points against structured constraint schemas, ensuring that application state and user input meet defined requirements.
The library distinguishes itself through its support for asynchronous validation, allowing for verification tasks that require external data sources or server-side checks. It includes a built-in utility for extracting and normalizing data from web forms, which cleans input by removing whitespace and empty values before validation occurs.
The engine features an extensible architecture that enables the registration of custom validation rules to meet specific domain requirements. Validation results are processed through a transformation pipeline, which converts raw error collections into structured formats suitable for user interface feedback.
Features
- Form Validation Libraries - Provides a declarative framework for verifying data objects and form inputs against custom constraints.
- Declarative Schemas - Enables defining validation logic through structured configuration objects that map data fields to specific constraints.
- JavaScript Object Validation - Verifies complex JavaScript objects against declarative constraints to ensure application state meets business requirements.
- Data Validation Schemas - Verifies complex data structures against declarative schemas to ensure input meets defined requirements.
- Form Data Validation - Collects and cleans user input from web forms to ensure data integrity before processing.
- Asynchronous Validators - Supports asynchronous validation rules that return promises to handle external server-side checks.
- Asynchronous Validation - Provides asynchronous validation capabilities that allow for external data lookups or network requests during the verification process.
- External Data Validation - Executes validation logic that requires external server-side checks or database lookups to confirm data validity.
- Validation Registries - Features an extensible architecture that allows developers to register custom validation rules into a central store.
- Custom Logic Validation - Allows developers to extend the validation engine by defining custom, reusable logic for specific domain requirements.
