Can it help with API documentation?

Yes, it automatically includes @nestjs/swagger decorators in backend DTOs, allowing for the automatic generation of interactive API documentation that stays in sync with your code.

Does it support Next.js Server Actions?

Absolutely. It includes templates for Server Actions that use the generated Zod schemas to validate input before calling the backend API, providing a seamless developer experience.

How does it ensure frontend and backend synchronization?

The skill generates matching validation logic using class-validator for NestJS and Zod for Next.js, ensuring that the data structures and constraints are identical on both sides of the contract.

Does it handle pagination?

Yes, it provides standardized Pagination DTOs and Meta types to ensure that list-based responses are handled consistently across all your API endpoints.

What happens if my backend uses a different language?

While optimized for the NestJS/Next.js ecosystem, the contract principles can be adapted to other TypeScript-based backends or used as a blueprint for cross-language type safety.

API 开发

Generates synchronized API contracts, DTOs, and validation schemas to ensure perfect communication between Next.js frontends and NestJS backends.

关于

The API Contracts Generator solves the common problem of fragmentation in full-stack applications by enforcing a unified contract between the frontend and backend. It automates the creation of NestJS DTOs with class-validator, matching TypeScript interfaces for the frontend, and synchronized Zod schemas for client-side validation. By standardizing error handling and automating Swagger documentation, this skill eliminates runtime type mismatches and ensures that validation rules are consistent across the entire stack, significantly reducing debugging time for API integrations.

主要功能

Synchronized DTO and interface generation for NestJS and Next.js
Unified validation rules using class-validator and Zod patterns
Standardized error response formatting for predictable error handling
Template-based generation for paginated queries and responses
64 GitHub stars
Automated Swagger/OpenAPI documentation decorators for backend endpoints

使用场景

Refactoring existing frontend-backend communication to eliminate type drift
Defining end-to-end type safety when building new REST API endpoints
Implementing complex multi-step forms that require identical validation logic on both tiers
