This course shows you how to build type-safe APIs with NestJS and oRPC. You work with shared Zod contracts, build clear CRUD endpoints, and create OpenAPI docs in a Turborepo setup. You write less boilerplate and keep your types in sync.
What You Build
You create a backend that checks data at each step. You use Zod to shape and validate input. You expose clean routes that match your contracts. You also sync these types across services in one repo.
CRUD with Strong Types
You define each route with Zod. You let NestJS use these types. This helps you catch errors early. It also keeps your code simple and clear.
Auto OpenAPI Docs
You generate OpenAPI docs from your Zod schemas. You do not repeat work. Your docs and your code stay aligned.
Full Stack Flow
You connect the backend to a React app. You use TanStack Query to call your API. You share the same types from backend to UI. This gives you end-to-end safety.
Typed Client Calls
Your frontend reads the same contracts as your backend. You call API methods with full type hints. You get safer code and faster feedback.
