You can use aws-sdk module for deleting folder. Because you can only delete a folder when it is empty, you should first delete the files in it. I'm doing it like this :

function emptyBucket(bucketName,callback){
  var params = {
    Bucket: bucketName,
    Prefix: 'folder/'
  };

  s3.listObjects(params, function(err, data) {
    if (err) return callback(err);

    if (data.Contents.length == 0) callback();

    params = {Bucket: bucketName};
    params.Delete = {Objects:[]};

    data.Contents.forEach(function(content) {
      params.Delete.Objects.push({Key: content.Key});
    });

    s3.deleteObjects(params, function(err, data) {
      if (err) return callback(err);
      if(data.Contents.length == 1000)emptyBucket(bucketName,callback);
      else callback();
    });
  });
}
