Bun Integration

Bun comes with a built-in, high-performance HTTP server that follows the Fetch API. For additional context, refer to the Fetch Server Integration guide.

Basic

import { RPCHandler } from '@orpc/server/fetch'
import { CORSPlugin } from '@orpc/server/plugins'

const handler = new RPCHandler(router, {
  plugins: [
    new CORSPlugin()
  ]
})

Bun.serve({
  async fetch(request: Request) {
    const { matched, response } = await handler.handle(request, {
      prefix: '/rpc',
      context: {} // Provide initial context if needed
    })

    if (matched) {
      return response
    }

    return new Response('Not found', { status: 404 })
  }
})

INFO

The handler can be any supported oRPC handler, such as RPCHandler, OpenAPIHandler, or another custom handler.
