import { createServer } from 'node:http'
import { OpenAPIHandler } from '@orpc/openapi/node'
import { CORSPlugin } from '@orpc/server/plugins'

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

const server = createServer(async (req, res) => {
  const result = await handler.handle(req, res, {
    context: { headers: req.headers }
  })

  if (!result.matched) {
    res.statusCode = 404
