i'm fetching some binary data over http. My code looks like:
var writeStream = fs.createWriteStream(fileName);
request(url, function(err, res) {
res.socket.pipe(writeStream);
});
now the output file is created but the filesize is 0. The url is correct though, i verified that with wget.
Thanks in advance & best regards

HTTP Streaming is a push-style data transfer technique that allows a web server to continuously send data to a client over a single HTTP connection that remains open indefinitely.
Methods to send response from server to client are:Using send() function. Using json() function.
Streams are one of the fundamental concepts that power Node. js applications. They are data-handling method and are used to read or write input into output sequentially. Streams are a way to handle reading/writing files, network communications, or any kind of end-to-end information exchange in an efficient way.
The callback for http.request only supplies one argument, which is a reference to the response of the request. Try
http.request(url, function(res) {
res.pipe(writeStream);
});
Also note that the ClientResponse implements ReadableStream, so you should use .pipe rather than .socket.pipe.
