Introduction

Zod is a TypeScript-first validation library that provides runtime validation.

• Runtime validation of API request and response payloads.
• Generating TypeScript types directly from validation schemas.
• Custom error messages and complex validation logic.
• Not natively compatible with OpenAPI/Swagger generation

JSON Schema is used to define the structure, types, and constraints of JSON data.

• Validating request and response payloads in APIs.
• Generating OpenAPI/Swagger documentation.
• Limited control over custom error messages
