oRPC is a powerful combination of RPC and OpenAPI, makes it easy to build APIs that are end-to-end type-safe and adhere to OpenAPI standards

Highlights

🔗 End-to-End Type Safety: Ensure type-safe inputs, outputs, and errors from client to server.
📘 First-Class OpenAPI: Built-in support that fully adheres to the OpenAPI standard.
📝 Contract-First Development: Optionally define your API contract before implementation.
⚙️ Framework Integrations: Seamlessly integrate with TanStack Query (React, Vue, Solid, Svelte, Angular), Pinia Colada, and more.
🚀 Server Actions: Fully compatible with React Server Actions on Next.js, TanStack Start, and other platforms.
🔠 Standard Schema Support: Works out of the box with Zod, Valibot, ArkType, and other schema validators.
🗃️ Native Types: Supports native types like Date, File, Blob, BigInt, URL, and more.
⏱️ Lazy Router: Enhance cold start times with our lazy routing feature.
📡 SSE & Streaming: Enjoy full type-safe support for SSE and streaming.
🌍 Multi-Runtime Support: Fast and lightweight on Cloudflare, Deno, Bun, Node.js, and beyond.
🔌 Extendability: Easily extend functionality with plugins, middleware, and interceptors.
🛡️ Reliability: Well-tested, TypeScript-based, production-ready, and MIT licensed.
