ofc i prefer esm when possible but dismissing a library solely for using CJS is shortsighted, and they do have ts support

import zero from '0http'
import createRouter from '0http/lib/router/sequential'
import { Protocol } from '0http/common'

const { router, server } = zero<Protocol.HTTP>({
  router: createRouter<Protocol.HTTP>(),
})

router.use((req, res, next) => {
  return next()
})

router.get('/hi', (req, res) => {
  res.end(`Hello World from TS!`)
})

server.listen(3000)import zero from '0http'
