Elysia is a high-performance web framework for Bun that adheres to the Fetch API. For additional context, refer to the HTTP Adapter guide.

Basic

import { Elysia } from 'elysia'
import { RPCHandler } from '@orpc/server/fetch'
import { onError } from '@orpc/server'

const handler = new RPCHandler(router, {
  interceptors: [
    onError((error) => {
      console.error(error)
    }),
  ],
})

const app = new Elysia()
  .all('/rpc*', async ({ request }: { request: Request }) => {
    const { response } = await handler.handle(request, {
      prefix: '/rpc',
    })

    return response ?? new Response('Not Found', { status: 404 })
  }, {
    parse: 'none' // Disable Elysia body parser to prevent "body already used" error
  })
  .listen(3000)

console.log(
  `🦊 Elysia is running at http://localhost:3000`
)

INFO

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