Typesafe APIs Made Simple 🪄

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, ensuring a smooth and enjoyable developer experience.

Highlights

• End-to-End Type Safety 🔒: Ensure complete type safety from inputs to outputs and errors, bridging server and client seamlessly.
• First-Class OpenAPI 📄: Adheres to the OpenAPI standard out of the box, ensuring seamless integration and comprehensive API documentation.
• Contract-First Development 📜: (Optional) Define your API contract upfront and implement it with confidence.
• Exceptional Developer Experience ✨: Enjoy a streamlined workflow with robust typing and clear, in-code documentation.
• Multi-Runtime Support 🌍: Run your code seamlessly on Cloudflare, Deno, Bun, Node.js, and more.
• Framework Integrations 🧩: Supports Tanstack Query (React, Vue), Pinia Colada, and more.
• Server Actions ⚡️: Fully compatible with React Server Actions on Next.js, TanStack Start, and more.
• Standard Schema Support 🗂️: Effortlessly work with Zod, Valibot, ArkType, and others right out of the box.
• Fast & Lightweight 💨: Built on native APIs across all runtimes – optimized for speed and efficiency.
• Native Types 📦: Enjoy built-in support for Date, File, Blob, BigInt, URL and more with no extra setup.
• Lazy Router ⏱️: Improve cold start times with our lazy routing feature.
• SSE & Streaming 📡: Provides SSE and streaming features – perfect for real-time notifications and AI-powered streaming responses.
• Reusability 🔄: Write once and reuse your code across multiple purposes effortlessly.
• Extendability 🔌: Easily enhance oRPC with plugins, middleware, and interceptors.
• Reliability 🛡️: Well-tested, fully TypeScript, production-ready, and MIT licensed for peace of mind.
• Simplicity 💡: Enjoy straightforward, clean code with no hidden magic.
