# Recommendation

* *Can Zod definitions be integrated without breaking Swagger/OpenAPI generation?*
  * **YES**, we can use Zod alongside JSON Schema for validation, but Swagger/OpenAPI must still rely on JSON Schema.
* *Does Zod improve type safety across request/response objects?*
  * **YES**
* *Is performance acceptable under expected load?*
  * **YES**, we tested a file with size of 10mb. We have not noticed any significant delay in the system.

- **Zod** is suitable for small payloads
- **Zod** is ideal for complex validations
- **Zod** supports custom error messages
- **JSON Schema** is performant
- **JSON Schema** is already integrated with request/response validation and OpenAPI generation
- **JSON Schema** is best for OpenAPI documentation or simple validation

# Recommendation

* Keep JSON Schema for OpenAPI/Swagger documentation.

* Use Zod for request payload validation in cases where JSON Schema is limited (example is file size validation or complex validation, custom user-friendly error message)

* Simplify payload handling using Zod for requests and responses while maintaining JSON Schema for API documentation

* Adopt both simultaneously where appropriate. JSON Schema ensures documentation consistency, and Zod provides runtime validation with friendly errors
