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

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.
• 🔍 First-Class OpenTelemetry: Seamlessly integrate with OpenTelemetry for observability.
• ⚙️ Framework Integrations: Seamlessly integrate with TanStack Query (React, Vue, Solid, Svelte, Angular), SWR, 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.

Generate OpenAPI specs and handle OpenAPI requests. Read the documentation for more information.

import { createServer } from 'node:http'
import { OpenAPIHandler } from '@orpc/openapi/node'
import { CORSPlugin } from '@orpc/server/plugins'

const handler = new OpenAPIHandler(router, {
  plugins: [new CORSPlugin()]
})

const server = createServer(async (req, res) => {
  const result = await handler.handle(req, res, {
    context: { headers: req.headers }
  })

  if (!result.matched) {
    res.statusCode = 404
    res.end('No procedure matched')
  }
})

server.listen(3000, '127.0.0.1', () => console.log('Listening on 127.0.0.1:3000'))
