Node.js & Amazon S3: How to iterate through all files in a bucket?

Question

Is there any Amazon S3 client library for Node.js that allows listing of all files in S3 bucket?

The most known aws2js and knox don\'t seem to have this functionalit

Answer 1

In fact aws2js supports listing of objects in a bucket on a low level via s3.get() method call. To do it one has to pass prefix parameter which is documented on Amazon S3 REST API page:

var s3 = require('aws2js').load('s3', awsAccessKeyId, awsSecretAccessKey);    
s3.setBucket(bucketName);

var folder = encodeURI('some/path/to/S3/folder');
var url = '?prefix=' + folder;

s3.get(url, 'xml', function (error, data) {
    console.log(error);
    console.log(data);
});

The data variable in the above snippet contains a list of all objects in the bucketName bucket.
