Send file from nodejs server to AngularJS client

Question

I want to send file from node.js server to client on Angular. I'm using fileSaver.js on client.

Server:

res.download('123.txt', function(err){
    if(err){
        console.log('error');
    }
})

Cliet:

$http.post('/downloadFile').success(function(res){
   var file = new Blob([res]);
   saveAs(file, '123.txt');
}

But it works only with .txt files. How to do this with other formats?
