I need to get an user download his file and remove it after response get finished:

app.get('/download/:file', function (req, res) {
   var filePath = '/files/' + req.param('file');
   res.download(file);

   fs.unlink(filePath); 
});

In the code above fs.unlink could invoked early than res.download will get finished.

node.js express download
