How to consume response from Knox module?

Question

I am using the Knox S3 module, but when I eventually get the file, the resulting file is corrupt. Am I using Knox incorrectly?

        var data;
        client.getFile(path, function(err, file) {
            file.on('data', function(chunk) { data += chunk; });
            file.on('end', function() {
                //Here I end up sending the response with new Buffer(data), but that produces a bad file.
            });
        });

Answer 1

Try using the writeStream:

var fs = require('fs');
var file = fs.createWriteStream(path);
client.getFile(path, function(err, stream) {
    stream.on('data', function(chunk) { file.write(chunk); });
    stream.on('end', function(chunk) { file.end(); });
});
