Simple NodeJS http server logging post requests

const http = require("http");
const qs = require('querystring');

const host = '0.0.0.0';
const port = 8000;

const requestListener = function (req, res) {
  if (req.method == 'POST') {
    let body = '';
    req.on('data', function (data) {
        body += data;
        if (body.length > 1e6) {
            req.connection.destroy();
        }
    });
    req.on('end', function () {
        let postData = qs.parse(body);
        // use POST
        console.log(new Date(), postData);
    });
  }

  res.writeHead(200);
  res.end("OK");
};

const server = http.createServer(requestListener);
server.listen(port, host, () => {
  console.log(`Server is running on http://${host}:${port}`);
});
