References

oRPC is inspired by existing solutions that prioritize type safety and developer experience. Special acknowledgments to:

• tRPC: For pioneering the concept of end-to-end type-safe RPC and influencing the development of type-safe APIs.
• ts-rest: For its emphasis on contract-first development and OpenAPI integration, which have greatly inspired oRPC's feature set.
