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