How to download a file on node.js?

Question

Node.js

There is a php page that gives the file for download:

$size=filesize("MyProgram.exe");
header("Content-Type: application/exe");
header("Content-Disposition: attachment; filename=MyProgram.exe");
header("Content-Length: $size");
header("Cache-control: private");

$filename="MyProgram.exe";
$fp =fopen($filename, 'r');
fpassthru($fp);
header("Location: MyProgram.exe");

I need to download it to node.js, but the usual save by link saves the page and not the file
. How to get exactly the file and not the page?
