Typesafe APIs Made Simple 🪄
Easy to build APIs that are end-to-end type-safe and adhere to OpenAPI standards

Summary
tRPC is a TypeScript library that enables end-to-end typesafe APIs with automatic type inference, zero build steps, and framework-agnostic adapters for React, Next.js, Express, and more.

- Uses Zod for input validation and supports queries, mutations, and subscriptions
