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 type { IncomingHttpHeaders } from 'node:http'
import { ORPCError, os } from '@orpc/server'
import * as z from 'zod'

const PlanetSchema = z.object({
  id: z.number().int().min(1),
  name: z.string(),
  description: z.string().optional(),
})

export const listPlanet = os
  .input(
    z.object({
      limit: z.number().int().min(1).max(100).optional(),
      cursor: z.number().int().min(0).default(0),
    }),
  )
  .handler(async ({ input }) => {
    // your list code here
    return [{ id: 1, name: 'name' }]
  })

export const findPlanet = os
  .input(PlanetSchema.pick({ id: true }))
  .handler(async ({ input }) => {
    // your find code here
    return { id: 1, name: 'name' }
  })

export const createPlanet = os
  .$context<{ headers: IncomingHttpHeaders }>()
  .use(({ context, next }) => {
    const user = parseJWT(context.headers.authorization?.split(' ')[1])

    if (user) {
      return next({ context: { user } })
    }

    throw new ORPCError('UNAUTHORIZED')
  })
  .input(PlanetSchema.omit({ id: true }))
  .handler(async ({ input, context }) => {
    // your create code here
    return { id: 1, name: 'name' }
  })

export const router = { planet: { list: listPlanet, find: findPlanet, create: createPlanet } }
