[http.IncomingMessage] `req.toWeb()`

What is the problem this feature will solve?

Reading the body out of the http.IncomingMessage is troublesome without any 3th party package...

Request on the other hand has features such as text, blob, json, arrayBuffer, formData bytes, and body for parsing it.

What is the feature you are proposing to solve the problem?

It would be a convenient to have something like a req.toWeb() utility added onto the simple http server 🚀

something like the stream.Readable.toWeb() but for the http.IncomingRequest to web Request

import http from 'node:http'

const app = http.createServer(async (req, res) => {
  const request = req.toWeb()
  
  await request.blob()
  await request.arrayBuffer()
  await request.bytes()
  await request.formData()
  await request.json()
  await request.body.pipeTo(dest)
  
  request.headers.has('content-length') // now getting the benefit of case insensitive.
  
  // full url (populated with host from request headers and http(s) based on using http or https)
  request.url 
  
  // a abort signal that aborts when user cancel the request
  // can be useful for aborting other pending database queries
  request.signal
})

What alternatives have you considered?

currently doing some simplier variant like this one:

const app = http.createServer((r, res) => {
  const req = new Request(r.url, {
    headers: r.headers,
    method: r.method,
    body: r
  })
})

having this req.toWeb() built in would be very handy

まず、既存の http.createServer/IncomingMessage の経路と、issue で指定されている stream.Readable.toWeb() API を読みます。提案されている body メソッド、headers、URL、abort signal の挙動を維持する web Request への変換を定義して検証します。これらのケースで要求された req.toWeb() インターフェースが動作すれば完了です。
