Node.js do I have to define on "data" event for GET requests?

What if someone sends a GET request with a body, or a POST request but without a body. In both cases, do I have still have to define the on "data" event?

request.on ("data", function (chunk) {

  // Might be a GET request or whatever.
  // Doesn't get fired when there is no body,
  // but must be present otherwise on "end" doesn't get fired

});

request.on ("end", function () {

  // Doesn't get fired unless on "data" is present
  // even if there is no body

});

Thanks.
