Build end-to-end type-safe APIs with tRPC, which infers input and output types from API paths.
About tRPC
tRPC builds APIs where the TypeScript client uses types exported from the server router. Developers define query, mutation, and subscription procedures in routers, validate input such as with Zod, serve the router over HTTP, and query it from a typed client without generated code.
Key features
- Define queries, mutations, and subscriptions grouped in routers
- Share server router types with client for TypeScript checking
- Validate procedure input with Zod validators
- Connect via adapters for Express, Fastify, AWS Lambda, and more
- Provide endpoint autocompletion matching backend API code
- Work without build step or generated client code
Best for: JavaScript developers using TypeScript who maintain a frontend and backend with shared types.
Good for
- No build, compile, or code generation step
- States zero dependencies with small client-side footprint
- Compatible with multiple JavaScript frameworks and runtimes
