where to see the response.write() messages

Question

I am using the follwing http request in my Angular JS code

$http.get('http://my url/.../')
       .success(function(data, status, headers, config){
          console.log('response',data);
       })
       .error(function() {
          console.log('Error');
        });

and in my node JS, I am using

response.write(data);

where can I get that data value. Because I am not getting the any console with the data. If I use

response.send(data);

then I am getting the console log from the my JS file with the data

Answer 1

The data is being sent in both cases. Only the send method closes the connection.

The issues is that the success callback only runs when the request completes . The write method sends data to the client, but it does not complete the request. The client is still waiting for the server to say, " Okay, that's the whole message; there's no more to send. " Until the server does that, the success callback won't run.

The send method (and the end method) close the connection. When the connection closes, the success method runs.

it appears that you want to send a continuous stream of data (since you don't want to end the connection), in which case, you could log XHR progress events . Unfortunately, the $http interface does not currently expose progress events .

I assume you are using Express with Node. With response.write , you are just writing the response without sending it. You then have to call response.end to say: "this response is ready, send it." response.send writes and sends the response.

response.send(data);

is the same as:

response.write(data);
response.end();

Answer 3

It should simply be:

response.end(data);

You have to end it to flush the response.
