body parser meddling with req.on('end') callback.

[arihant daga]

A weird bug started coming up recently.
I have defined

req.on('end', ()=>{
    console.log('Request Ended,. Reduced active request counter');
});

But surprisingly if i am including body-parser this callback is not being called.

P.S - This is how i am including body-parser. Is there anything wrong with it ?

app.use(bodyParser.urlencoded({ extended: true }));
app.use(bodyParser.json());

Hi @arihantdaga this is because body parser reads the request to completion before moving on to the next middleware. This is why the entire body is present in req.body. In Node.js, once you have consumed the stream, you can not consume it a second time.
