I korthet

tRPC lets you build type-safe APIs without REST endpoints or schemas. Define procedures (functions) in TypeScript on the server, call them directly from the frontend with full type inference. No API documentation needed, types are the contract. Used in modern full-stack apps (Next.js, SvelteKit, etc.) for developer ergonomics and type safety. Takes 2-3 weeks to master. Sits between REST (verbose, type-unsafe) and GraphQL (powerful, complex) as the pragmatic TypeScript-only option.

Vad är tRPC Type Safe API

tRPC (TypeScript Remote Procedure Call) is a framework for building end-to-end type-safe APIs. You define server-side functions (procedures) in TypeScript, and tRPC generates a strongly-typed client for your frontend. Call server functions directly from your frontend with full autocomplete and type checking, no REST endpoints, no API documentation, no serialization gaps. tRPC is ideal for full-stack TypeScript apps (Next.js, SvelteKit, Remix). The backend and frontend share the same types, so changes propagate automatically.

❓ Vanliga frågor

Is tRPC a REST replacement?
Yes, for internal APIs. tRPC is ideal for monoliths and tightly-coupled client-server apps. For public APIs or mobile clients, REST/GraphQL are better.
Do I need REST endpoints with tRPC?
No. tRPC replaces REST. Call server functions directly from the frontend. tRPC handles serialization and transport.
Is tRPC production-ready?
Yes. tRPC is used in production by many companies. Stable API, active maintenance, great community.
Does tRPC work with non-TypeScript clients?
tRPC is TypeScript-first. OpenAPI (REST) generation is being worked on, but tRPC shines with TypeScript frontends (Next.js, SvelteKit, etc.).
What happens with tRPC if TypeScript types change?
Frontend code won't compile if you change server types. tRPC enforces type safety at the boundary.
