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.

Provides ValibotToJsonSchemaConverter for generating OpenAPI specs from Valibot.

Generate OpenAPI Spec

import { OpenAPIGenerator } from '@orpc/openapi'
import { experimental_ValibotToJsonSchemaConverter as ValibotToJsonSchemaConverter } from '@orpc/valibot'

const openAPIGenerator = new OpenAPIGenerator({
  schemaConverters: [
    new ValibotToJsonSchemaConverter()
  ],
})

const specFromContract = await openAPIGenerator.generate(contract, {
  info: {
    title: 'My App',
    version: '0.0.0',
  },
})

const specFromRouter = await openAPIGenerator.generate(router, {
  info: {
    title: 'My App',
    version: '0.0.0',
  },
})
