In my services.service.ts file I am passing a name of a zip and calling the route

services.service.ts

downloadFile(name) 
 console.log(name);
 let newName = name+".zip";
 console.log(newName);
 return this.http
 .get(`/services/downloadFile/$name`, 
 responseType: ResponseContentType.Blob )
 .pipe(map(res => 
 return 
 filename: newName,
 data: res.blob()
 ;
 ))
 .subscribe(res => 
 // console.log('start download:',res);
 var url = window.URL.createObjectURL(res.data);
 var a = document.createElement('a');
 document.body.appendChild(a);
 a.setAttribute('style', 'display: none');
 a.href = url;
 a.download = res.filename;
 a.click();
 window.URL.revokeObjectURL(url);
 a.remove(); // remove the element
 , error => 
 console.log('download error:', JSON.stringify(error));
 , () => 
 console.log('Completed file download.')
 );

After i call this route from service.js the zip file gets downloaded to windows but with no data
service.js

router.get('/downloadFile/:name', function (req, res) 
 let name = req.params.name;
 let newName = name+".zip";
 res.download(`./config/$newName`, newName, function (err) 

 if (err) 
 console.log(err);
 console.log("ERROR APPEARED");
 else 
 console.log('file uploaded :)');
 
 );
);

This code executes with no errors (I will get "file uploaded :)" in a console) but the downloaded zip I wont be able to open or extract because it will not contain data (appropriate data)

I've encountered a similar problem once - In case you use token-based auth you probably forgot to add these in your headers, try:

.get(`/services/downloadFile/$name`, headers: new Headers(
 'Content-Type': 'application/json', // INFO: Format set to JSON
 'authorization': yourAuth.token.etc // INFO: Attach token
 ),responseType: ResponseContentType.Blob )

Hope that helps to you solve your issue..
