Express.js Adapter

Express.js integration.

Express's body-parser handles common content types and oRPC will use the parsed body. But it doesn't support Bracket Notation. Register body-parsing middleware after your oRPC middleware or only on non-oRPC routes.

Basic

import express from 'express'
import cors from 'cors'
import { RPCHandler } from '@orpc/server/node'
import { onError } from '@orpc/server'

const app = express()
app.use(cors())

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

app.use('/rpc{/*path}', async (req, res, next) => {
  const { matched } = await handler.handle(req, res, {
    prefix: '/rpc',
    context: {},
  })

  if (matched) return
  next()
})

app.listen(3000, () => console.log('Server listening on port 3000'))

The handler can be any supported oRPC handler.
