Explained with a Demo Project **[freeCodeCamp](https://daily.dev/sources/freecodecamp)** · 17 min read · 47 upvotes · 1 comments ## Summary tRPC is a type-safe TypeScript-based library that enhances the RPC API design for handling API requests and responses. It eliminates the need for traditional REST and Fetch APIs by using a query system that ensures data integrity between the client and server. By leveraging TypeScript and the Zod library, tRPC ensures that data types match between the front end and back end, preventing errors. This post explains tRPC's benefits, setup, and usage through a detailed demo project that integrates tRPC with React and Express. ## Full article daily.dev links to this article rather than hosting it.
