# tRPC Protocol

> **Definition:** tRPC is a protocol that allows developers to build end-to-end type-safe APIs without code generation by sharing TypeScript type definitions between the backend server and frontend client.

## In depth

tRPC eliminates API contract drift. By utilizing the TypeScript compiler, tRPC ensures that if a backend query database model changes, the frontend code fails to build. This guarantees that frontend views match backend data properties, eliminating runtime JSON property undefined crashes.

## How ERPStack applies this

We build all custom admin and user dashboards with tRPC, ensuring complete type safety from our database schemas directly to our React views.
