Descrition
validator-is: Simplify Your Validation and Swagger Documentation
validator-is is a powerful Javascript/TypeScript library that bridges the gap between class-validator and Swagger documentation. It provides a set of decorators that simultaneously validate your data using class-validator and generate corresponding Swagger/OpenAPI documentation.
Key Features:
- Single decorator for both validation and API documentation
- Seamless integration with class-validator and Swagger/OpenAPI
- Type-safe and easy to use with TypeScript
- Reduces code duplication and improves maintainability
- Customizable validation rules and Swagger properties
- Supports nested objects and complex data structures
Whether you're building a REST API or a full-stack application, validator-is simplifies your development process by unifying data validation and API documentation in one step. Say goodbye to inconsistencies between your validation logic and API specs, and hello to a more efficient, error-free development experience.
Compatible with NestJS Frameworks. MIT Licensed.
