TypeScript API teams struggle to maintain type safety, validation, and scalable architecture across Express/Fastify services.
Start by scaffolding a minimal Express API with typed DTOs and Zod validation to expose a REST endpoint.

Build a type-safe REST API with TypeScript by enforcing typed routes and runtime input validation with Zod. This ensures correct client-server contracts through typed DTOs while maintaining clear separation between routes, controllers, services, and models.
Structure a scalable TypeScript API by enforcing a clean separation between routes, controllers, services, and models. This architectural pattern applies to both Express and Fastify stacks, ensuring maintainability across backend services and microservices.
Yes, you can use Zod for runtime request validation in an Express API. It enforces type-safe routing and validates input data against typed DTOs, ensuring that incorrect client-server contracts are rejected before reaching your business logic.
Yes, this TypeScript API approach works with both Express and Fastify. It provides end-to-end patterns for scalable architecture, applying typed routes and Zod validation across both web frameworks to maintain consistent type safety.
TypeScript provides compile-time type safety, but runtime validation with Zod is needed to validate incoming API requests. Zod enforces typed DTOs at runtime, ensuring correct client-server contracts and preventing invalid data from entering your backend services.
Separate controllers and services in a TypeScript API when building scalable backend services or microservices. This clear separation isolates business logic from routing, ensuring type-safe architecture remains maintainable as the API grows.
