addEventListener("fetch", event => {
  event.respondWith(fetchAndStream(event.request))
})

async function fetchAndStream(request) {
  // Fetch from origin server.
  let response = await fetch(request)

  // Create an identity TransformStream (a.k.a. a pipe).
  // The readable side will become our new response body.
  let { readable, writable } = new TransformStream()

  // Start pumping the body. NOTE: No await!
  response.body.pipeTo(writable)

  // ... and deliver our Response while that’s running.
  return new Response(readable, response)
}

Closing for now... Stream tradeoffs can be avoided with better filetype detection.
