Piping the response to a end file: get response status

How can I get response status if response is piped to file stream?

See code:

var client = supertest(...);
...
// Create writable stream
var writeStream = temp.createWriteStream();
temp.track();

// Superagent request
var req = client.get('/...');

req.on('end', function() {
    // Here we can read file content
    // It can contain actual file content
    // Or JSON string representing error
    // For example {'code': 'F-0001' , 'message': 'File not found'}
    // We should parse this if response code != 200
    // How can we get it here?
    ...
});

// Piping the response to a file
req.pipe(writeStream);

Try this:

req.on('response', function( res ) {
  console.log(res.status);
});

I’ve tried this and the ‘response’ callback do not work with get requests.

I’m not sure if this is the ‘proper way’ to do this, but if you really need it, you can access the response status code in the ‘end’ callback doing

this.res.statusCode;

This breaks encapsulation, so be aware that it might change in future superagent versions.
