H2c Server

An http.listen server that transparently serves HTTP/2 cleartext (h2c) as well as HTTP/1.1. No API change: a connection whose first bytes are the HTTP/2 preface is driven by the nghttp2 session driver and dispatched through the same handler; everything else is HTTP/1.1. Needs libnghttp2 installed on the build machine (linked only for http.listen).

curl --http2-prior-knowledge http://localhost:8090/hello # served over h2 curl http://localhost:8090/hello # served over 1.1

Self-closes after a short delay so it runs to completion unattended.

import http from 'http'

interface Res {
  status: number
  body: string
}

setTimeout(() => {
  console.log('auto-closing after demo delay')
  http.close()
}, 300)

console.log('listening on :8090 (HTTP/1.1 + h2c)')

http.listen(8090, (req: HttpRequest): Res => {
  return { status: 200, body: 'hello (' + req.method + ' ' + req.path + ')' }
})

console.log('server closed, exiting')
