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.

@orpc/contract

Build your API contract. Read the documentation for more information.

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

export const listPlanetContract = oc
  .input(
    z.object({
      limit: z.number().int().min(1).max(100).optional(),
      cursor: z.number().int().min(0).default(0),
    }),
  )
  .output(z.array(PlanetSchema))

export const findPlanetContract = oc
  .input(PlanetSchema.pick({ id: true }))
  .output(PlanetSchema)

export const createPlanetContract = oc
  .input(PlanetSchema.omit({ id: true }))
  .output(PlanetSchema)

export const contract = {
  planet: {
    list: listPlanetContract,
    find: findPlanetContract,
    create: createPlanetContract,
  },
}
