What is tRPC?
tRPC enables end-to-end typesafe APIs in TypeScript. Define API procedures on the server and call them from the client with full type inference - no codegen or schemas needed. Works with React, Next.js, and other frameworks. Automatic type errors when API changes. Query and mutation patterns familiar to React Query users. Build APIs faster with confidence that types match from database to UI.

tRPC FAQ
How does tRPC ensure type safety across an application?
tRPC provides end-to-end typesafe APIs in TypeScript by allowing developers to define API procedures on the server and call them from the client with full type inference. This eliminates the need for codegen or schemas, ensuring that type errors are automatically caught when API definitions change.
What kind of user benefits most from tRPC?
tRPC is ideal for development teams working with TypeScript who want to build APIs faster with confidence in type consistency from the database to the UI. It particularly suits projects using React, Next.js, or similar frameworks that benefit from its query and mutation patterns.
How does tRPC compare to GraphQL for API development?
Unlike GraphQL, tRPC achieves end-to-end typesafety without requiring codegen or schemas. tRPC focuses on leveraging TypeScript's type inference directly, whereas GraphQL typically relies on schema definitions and code generation for type safety.
What are the main limitations when adopting tRPC?
The primary limitation of tRPC is its strict requirement for TypeScript. Projects not built with TypeScript will not be able to leverage its core benefits of end-to-end type safety and automatic type inference.
Can tRPC integrate with popular frontend frameworks?
Yes, tRPC is designed to work effectively with popular frontend frameworks. It explicitly supports integration with React and Next.js, and its approach to API development can be applied to other frameworks as well.
How is tRPC priced?
tRPC is free to use, meaning there is no paid plan required to access its features for building typesafe APIs. It offers its full functionality without any associated costs.
