Hey API Integration

Easily convert a Hey API generated client into an oRPC client to take full advantage of the oRPC ecosystem.

Installation

npm

npm install @orpc/hey-api@latest

yarn

yarn add @orpc/hey-api@latest

pnpm

pnpm add @orpc/hey-api@latest

bun

bun add @orpc/hey-api@latest

deno

deno install npm:@orpc/hey-api@latest

Generating an Hey API Client

To generate a Hey API client, run the following command:

npx @hey-api/openapi-ts \
  -i https://get.heyapi.dev/hey-api/backend \
  -o src/client \
  -c @hey-api/client-fetch

This command uses the OpenAPI spec at https://get.heyapi.dev/hey-api/backend and outputs the generated client into the src/client directory. And make sure you have @hey-api/client-fetch installed.

INFO

For more information on Hey API, please refer to the official documentation.

Converting to an oRPC Client

Once the client is generated, convert it to an oRPC client using the toORPCClient function:

import { experimental_toORPCClient } from '@orpc/hey-api'
import * as sdk from 'src/client/sdk.gen'

export const client = experimental_toORPCClient(sdk)

const { body } = await client.listPlanets()

This client now behaves like any standard oRPC server-side client or client-side client, allowing you to use it with any oRPC-compatible library.

Error Handling

Internally, oRPC passes the throwOnError option to the Hey API client. If the original Hey API client throws an error, oRPC will forward it as is without modification ensuring consistent error handling.
