tRPC enables end-to-end type safety between client and server without code generation or schemas.
Install required packages, create a simple router, and import the procedures on the client to call them with type-safe inference.

End-to-end type safety connects your client and server through shared TypeScript types without code generation. tRPC infers types automatically from your server procedures, so client calls validate against server definitions at compile time. Install tRPC and Zod, define your router with typed procedures, and import it on the client to get full type inference on every call.
Yes. tRPC eliminates schema files by using TypeScript types directly. You define procedures on the server with Zod input validation, and the client receives type-safe inference automatically. This works with Next.js, React, Express, and any full-stack TypeScript setup where you control both ends.
tRPC uses shared TypeScript types instead of schemas or code generation, eliminating runtime overhead and synchronization gaps. It batches requests automatically, provides zero-cost type safety, and requires no separate API documentation—your types are your contract.
tRPC integrates Zod for input validation. Define schemas on your procedures, and invalid requests fail with explicit TRPCError. Validation runs at the server boundary, and TypeScript ensures type-safe access to parsed inputs.
No. tRPC requires TypeScript on both client and server, and you must control both codebases to share types. If you consume external APIs or use non-TypeScript clients, REST or GraphQL are better fits.
Yes. tRPC supports middleware for cross-cutting concerns like authentication and logging. Use explicit TRPCError for structured error handling, and middleware wraps procedures to intercept requests and responses.
