End-to-end type-safe APIs for TypeScript with zero code generation.

• Shares TypeScript types between client and server automatically—no codegen required, with full type inference across queries, mutations, and subscriptions
• Integrates seamlessly with React Query for caching, optimistic updates, and infinite queries; supports Next.js App Router, Server Components, and WebSocket subscriptions
• Validates all inputs with Zod schemas; includes middleware for authentication, logging, and rate limiting; error handling with typed TRPCError codes
• Supports batching, DataLoader patterns, file uploads via signed URLs, and production patterns like caching, monitoring, and OpenTelemetry tracing
