getObject returns corrupted file?

[radekg]

I trying different variants of this:

I also seem to be getting a corrupted file, few KBs off. Do you have a working example?

Answering my own question:

var writePos = 0;
var stream = fs.createWriteStream("/tmp/test.jpg", { flags: 'w', encoding: null, mode: 0666 });
s3.client.getObject({ Bucket: bucket, Key: key }).data(function(data) {
    stream.write(data.data);
}).done(function() {
    stream.end();
}).send();

I've installed this package from master and this example has stopped working.

TypeError: Object #<Request> has no method 'data'

We've made changes to the Request class API since 0.9.1.pre-2. The changes are currently only in master and have not yet been released, so there isn't much available documentation. This will change by the next release, but to quickly get you going, you can rewrite the above as:

var stream = fs.createWriteStream("/tmp/test.jpg", { flags: 'w', encoding: null, mode: 0666 });
s3.client.getObject({ Bucket: bucket, Key: key }).on('httpData', function(chunk) {
    stream.write(chunk);
}).on('complete', function() {
    stream.end();
}).send();

Note that we may be adding more streaming support before the next preview release, so the API might be simplified considerably to something like:

var out = fs.createWriteStream("/tmp/test.jpg", { flags: 'w', encoding: null, mode: 0666 });
s3.client.getObject({ Bucket: bucket, Key: key }).createReadStream().pipe(out);

I would suggest that you should run off of the npm package releases until the next preview is out unless you explicitly want to experiment with the current features that are in the works-- with the caveat that some documentation may not be in sync until we push out the next release.

Yes, yes, I've found it. The changes were implemented here: #22, thank you.
