HTTP echo server in node

http_echo.js

const http = require('http')

const server = http.createServer((req, res) => {
  let response = `URL(${req.url.length}): ${req.url}\r\nHeaders: ${JSON.stringify(req.headers)}\r\n\r\n`
  res.end(response)
  console.log(response)
})

server.on('clientError', (err, socket) => {
  socket.end('HTTP/1.1 400 Bad Request\r\n\r\n')
})
server.listen(8081)

Just a dumb HTTP server that will listen on port 8081 and respond back with URL / URL Length and headers as well as output to console.
