SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

End-to-end type-safe APIs are essential for reliable, scalable TypeScript apps; tRPC enables seamless server-client contracts without code generation or GraphQL complexity.

Core Features & Use Cases

  • End-to-end type-safe APIs with tRPC and Next.js integration
  • Zod-based input validation and schema inference
  • Nested routers, middleware-based protected procedures, and clean composition
  • Use cases include internal tools, dashboards, and internal API surfaces for large TypeScript apps

Quick Start

Create a Next.js project and integrate the tRPC setup to expose a type-safe API route and consume it from a client.

FAQPage Schema
How do I build end-to-end type-safe APIs in Next.js without code generation?

End-to-end type-safe APIs in Next.js are built using tRPC to establish a single source of truth for API contracts, enabling robust type inference across server and client without requiring code generation.

Does tRPC work with Next.js App Router and React Query?

tRPC works seamlessly with Next.js App Router and React Query, supporting full-stack TypeScript projects to expose type-safe API routes and consume them directly from client components.

How do I validate inputs and infer types in a TypeScript API?

Inputs in a TypeScript API are validated using Zod-based schemas, where tRPC leverages Zod for input validation and schema inference to ensure server-client data contracts remain strictly typed.

Can I create nested routers and protected procedures in tRPC?

Nested routers and protected procedures are fully supported in tRPC, allowing you to compose clean nested routers and apply middleware-based protected procedures to secure internal API surfaces.

What is the best way to maintain server-client API contracts in large TypeScript apps?

The best way to maintain server-client API contracts in large TypeScript apps is using tRPC, providing a single source of truth with zero code generation for internal tools and dashboards.
