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.

import { createORPCClient } from '@orpc/client'
import { RPCLink } from '@orpc/client/fetch'
import { ContractRouterClient } from '@orpc/contract'
import { RouterClient } from '@orpc/server'

const link = new RPCLink({
  url: 'http://localhost:3000/rpc',
  headers: () => ({
    authorization: 'Bearer token',
  }),
  // fetch: <-- provide fetch polyfill fetch if needed
})

// Create a client for your router
const client: RouterClient<typeof router> = createORPCClient(link)
// Or, create a client using a contract
const client: ContractRouterClient<typeof contract> = createORPCClient(link)
