Build type-safe Node.js APIs by combining Express with TypeScript strict mode, Prisma ORM for database access, and Zod for input validation. This enforces compile-time type checking across routes, services, and database models, eliminating runtime type errors and ensuring consistent API contracts.

Zod provides schema-based validation for API requests, parsing and validating incoming data before it reaches your business logic. Combined with Express middleware, it catches invalid input early, returns structured error responses, and ensures type safety throughout your request handlers.

Yes, Prisma ORM works with both Express and Fastify frameworks. Set up a Prisma Client singleton to manage database connections efficiently, define your schema in schema.prisma, and access your database through type-safe generated client methods in your service layer.

Follow the service layer pattern: keep controllers thin and move business logic into dedicated service files. Services encapsulate data access through Prisma, validation through Zod, and reusable logic that can be tested independently and shared across multiple routes.

Your project requires Node.js 18 or higher and TypeScript in strict mode. You'll need a configured package.json, a server entry point (server.ts or index.ts), a Prisma schema for your database, and environment configuration files for 12-Factor compliance.

Yes, it automates REST API setup with custom error handling middleware, structured routing, CORS and helmet security middleware, and JWT authentication support. All error responses follow a consistent format defined by your middleware stack.
