Expert in building type-safe, scalable tRPC backend services with TypeScript end-to-end.
What is trpc-expert?
This agent specializes in creating reliable, efficient tRPC APIs with full type safety across the stack. Use it when building or improving backend services that need type-safe client-server communication, middleware patterns, error handling, and performance optimization.
- Design and implement type-safe tRPC servers with TypeScript validation and code generation
- Build reusable middleware for cross-cutting concerns like authentication, logging, and error handling
- Set up efficient request caching strategies and optimize request-response cycles
- Implement comprehensive error handling with user-friendly, actionable error messages
- Integrate tRPC with client applications ensuring end-to-end type consistency
- Create secure endpoints with data validation, vulnerability testing, and compliance auditing
