How do i stream response in express

Question

I\'ve been trying to get a express app to send the response as stream.

var Readable = require(\'stream\').Readable;
var rs = Readable();


app.get(\'/report\

I was able to get this to work.

• Put this code in your Express router.
• Open a web browser
• Go to http://yourdomain/yourrouterpath/stream

...

router.get('/stream', function (req, res, next) {
  //when using text/plain it did not stream
  //without charset=utf-8, it only worked in Chrome, not Firefox
  res.setHeader('Content-Type', 'text/html; charset=utf-8');
  res.setHeader('Transfer-Encoding', 'chunked');

  res.write("Thinking...");
  sendAndSleep(res, 1);
});


var sendAndSleep = function (response, counter) {
  if (counter > 10) {
    response.end();
  } else {
    response.write(" ;i=" + counter);
    counter++;
    setTimeout(function () {
      sendAndSleep(response, counter);
    }, 1000)
  };
};
