Typed API Contracts

Summary

Going a step further than shared types — tools like tRPC or a typed OpenAPI client generate full, type-safe API calls so a backend change breaks your frontend build immediately instead of silently at runtime.

• 1Explore tRPC's approach to end-to-end type safety without manual API documentation.
• 2Compare it to generating a typed client from an OpenAPI/Swagger spec.
• 3Understand the core value: catching frontend/backend mismatches at compile time, not in production.
