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.
