SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

This Skill addresses the challenge of maintaining consistency and preventing runtime errors in API communication by establishing a single source of truth for API structures.

Core Features & Use Cases

  • Schema Definition: Define API request, response, and error structures using Zod schemas.
  • Runtime Validation: Enforce data integrity on server-side request inputs and client-side API responses.
  • Type Inference: Automatically generate TypeScript types from Zod schemas for seamless integration.
  • Use Case: Ensure that user registration API endpoints always receive and return data in the expected format, preventing common "undefined is not a function" errors in the frontend.

Quick Start

Use the api-contracts-and-validation skill to define a Zod schema for a new user object.

FAQPage Schema
How do I validate API request bodies and responses in TypeScript?▼

API contracts are strict schema definitions that enforce data consistency between client and server. Using Zod, they provide runtime validation for request bodies and query inputs, preventing unexpected undefined errors in your application.

How do I define API contracts with Zod to prevent frontend crashes?▼

To define API contracts with Zod, create schemas for your API endpoints that validate request bodies, parameters, and query inputs. This enforces strict data integrity on the server and strips unknown fields, preventing unexpected frontend crashes.

Does Zod schema validation automatically generate TypeScript types for API responses?▼

Yes, Zod schema validation automatically generates TypeScript types from your defined API contracts. This type inference ensures seamless integration, allowing your client and server to share strictly typed structures for request bodies and responses.

What is the best way to enforce strict API schema definitions and strip unknown fields?▼

The best way to enforce strict API schema definitions and strip unknown fields is to implement Zod schemas for runtime validation. This handles optional fields correctly and maintains a single source of truth for all API communication structures.

Why should I use Zod schemas for client-side API response validation?▼

You should use Zod schemas for client-side API response validation to prevent application crashes caused by unexpected data formats. It ensures the frontend strictly processes data matching the defined API contract, stripping unknown fields automatically.
