How do you download a file from AWS S3 to a client's device?

Solution 1
S3 supports the ability to generate a pre-signed URL via the AWS Javascript API. Users can then GET
this URL to download the S3 object to their local device.
See this question for a Node.js
code sample.
Solution 2
you can use SignedURL Like that
var params = {Bucket: bucketname , Key: keyfile , Expires: 3600 , ResponseContentDisposition : `attachment; filename="filename.ext"` };
var url = s3.getSignedUrl('getObject', params);
the generated link will force download with the name filename.ext

Have looked at all the tutorials on how to download files from S3 to local disk. I have followed all the solutions and what they do is download the file to the server and not to the client. The code I currently have is
app.get('/download_file', function(req, res) { var file = fs.createWriteStream('/Users/arthurlecalvez/Downloads/file.csv'); file.on('close', function(){console.log('done'); }); s3.getObject({ Bucket: 'data.pool.al14835', Key: req.query.filename }).on('error', function (err) { console.log(err); }).on('httpData', function (chunk) { file.write(chunk); }).on('httpDone', function () { file.end(); }).send(); res.send('success') })
How do I then send this to the client so that it is downloaded onto their device?
