SimpleS3 is a very simple S3 http client. It wraps hyperquest for HTTP requests, and faketoe for xml parsing.



npm install simples3


Simply pass a config in with a key, secret, and optional host (host defaults to Amazon's S3 service)

var config = {
  key: 'AWSKEY',
  secret: 'AWSSECRET',
  host: ''
  simpleS3 = require('simples3'),
  s3Store = simpleS3.createClient(config);

List buckets

s3Store.getBuckets(function _bucketList(err, buckets) {

Bucket info

s3Store.getBucket('myBucket', function _bucketInfo(err, bucketInfo) {
  //To get just the files in the bucket

Create bucket

s3Store.createBucket('newBucket', function _newBucket(err, newBucket) {
  //Returns the created bucket info

Delete bucket

s3Store.deleteBucket('badBucket', function _deletedBucket(err, deletedBucket) {
  //Returns info for the deleted bucket

Get object

// Note that this returns a response object from S3 as well as the object
s3Store.getObject('myBucket', 'objectId', function _responseObject(err, response, myObject) {

// This function also returns a stream that can be piped directly to a writable stream
s3Store.getObject('myBucket', 'objectId').pipe(fs.createWriteStream('./temp.out'));

Get signed url to object

var expires = new Date();
expires.setHours(expires.getHours() + 1); // JavaScript date object: one hour from now
s3store.getObjectUrl('myBucket', 'objectId', expires, function _objectUrl(err, url) {

Create object

// You can either send data directly
var fileinfo = {
  data: fs.readFileSync('./images/funny/cat_macro.png'),
  type: 'image/png'

s3Store.createObject('myBucket', 'cat_macro.png', fileInfo, function _newObject(err, object) {
  //Returns info for the uploaded object

// Or you can provide some metadata and stream the data
var fileinfo = {
  type: 'image/png',
  size: 65432 // you're on your own to determine this before starting the stream

fs.createReadStream('./images/funny/cat_macro.png').pipe(s3Store.createObject('myBucket', 'cat_macro.png', fileInfo, function _newObject(err, object) {
  //Returns info for the uploaded object
  console.log(object); //Object id will be 'cat_macro.png'

Update object

Works just like creating an object, just use updateObject instead. There isn't much of a distinction between the two in S3

Delete object

s3Store.deleteObject('myBucket', 'cat_macro.png', function _deletedObject(err, deletedObject) {
  //Returns info on the deleted object

Parse a url

s3Store.parseUrl('', function (err, result) {
  // Returns an object with 'bucket' and 'resource' properties

// Also works synchronously
var parts = s3Store.parseUrl('');
