End-to-end typesafe APIs built quicker & easier
Note
This project is still in heavy development, please be mindful of breaking changes.
oRPC is a powerful combination of RPC and OpenAPI, offering an exceptional developer experience powered by TypeScript. It's designed to be simple and straightforward to use.
- Type-safe 🔒: oRPC is built on top of TypeScript, which means you get full type safety out of the box.
- Easy to use ✍️: oRPC is designed to be simple and straightforward to use.
- Contract first 📝: Take advantage of a "contract first" approach to developing your API.
- Built-in plugins 🔌: Easily implement into your favourite frameworks.
You can find the full documentation & examples here.
@orpc/contract: Build your API contract.@orpc/server: Build your API or implement API contract.@orpc/client: Consume your API on the client with type-safety.@orpc/react-query: Integration with React Query.@orpc/vue-query: Integration with Vue Query.@orpc/vue-colada: Integration with Pinia Colada.@orpc/openapi: Generate OpenAPI specs and provide OpenAPI handler for@orpc/server.@orpc/next: Helpers and hooks for Next.JS.@orpc/zod: More schemas that Zod doesn't support yet.

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.
