title: How to get byte size of request?
body: <p>I am making an API in Node.js Express which might get large requests coming in. <strong>I would really like to see how big the request are.</strong> </p>
  
  <pre><code>//....
  router.post('/apiendpoint', function(req, res, next) {
    console.log("The size of incoming request in bytes is");
    console.log(req.????????????); //How to get this?
  });
  //....
  </code></pre>
