Streaming-S3

A simple and light-weight S3 upload streaming module for NodeJS.

Benefits & Features

Super fast and super easy to use
Low memory usage
Nothing is written to disk during upload
Parallel part uploading
No need to know total size of the object
Implicit retry mechanism for failed part uploads
Tons of configurable options
Simple interface (Asynchronous and evented)
Downloading and uploading statistics (U/D speed and U/D time)
Proper usage of streams and graceful error handling
Production ready (Used and tested on production environments, uploading gigabytes of files to S3)
Uses official AWS SDK

Installation

$ npm install streaming-s3

Version 0.4 and 0.3.x Changes

Starting from version 0.4 onwards you can pass in an object that is used to configure the underlying aws-sdk. This can contain region and other parameters.

Old Constructor (Still supported)

var uploader = new streamingS3(fStream, 'accessKey', 'secretKey', ...

New Constructor

var uploader = new streamingS3(fStream, {accessKeyId: 'accessKey', secretAccessKey: 'secretKey'}, ...

Example Usage

Example 1: Uploading local file with callback.

var streamingS3 = require('streaming-s3'),
    fs = require('fs');

var fStream = fs.createReadStream(__dirname + '/video.mp4');
var uploader = new streamingS3(fStream, {accessKeyId: 'accessKey', secretAccessKey: 'secretKey'},
  {
    Bucket: 'example.streaming-s3.com',
    Key: 'video.mp4',
    ContentType: 'video/mp4'
  },  function (e, resp, stats) {
  if (e) return console.log('Upload error: ', e);
  console.log('Upload stats: ', stats);
  console.log('Upload successful: ', resp);
  }
);

Example 2: Uploading local file without callback.

var streamingS3 = require('streaming-s3'),
    fs = require('fs');

var fStream = fs.createReadStream(__dirname + '/video.mp4');
var uploader = new streamingS3(fStream, {accessKeyId: 'accessKey', secretAccessKey: 'secretKey'},
  {
    Bucket: 'example.streaming-s3.com',
    Key: 'video.mp4',
    ContentType: 'video/mp4'
  }
);

uploader.on('data', function(bytesRead) {
  console.log(bytesRead, ' bytes read.');
});

uploader.on('part', function(number) {
  console.log('Part ', number, ' uploaded.');
});

// All parts uploaded, but upload not yet acknowledged.
uploader.on('uploaded', function(stats) {
  console.log('Upload stats: ', stats);
});

uploader.on('finished', function(resp, stats) {
  console.log('Upload finished: ', resp);
});

uploader.on('error', function(e) {
  console.log('Upload error: ', e);
});

uploader.begin(); // important if callback not provided.

Example 3: Uploading remote file without callback and options

var streamingS3 = require('streaming-s3'),
    request = require('request');

var rStream = request.get('http://www.google.com');
var uploader = new streamingS3(rStream, {accessKeyId: 'accessKey', secretAccessKey: 'secretKey'},
  {
    Bucket: 'example.streaming-s3.com',
    Key: 'google.html',
    ContentType: 'text/html'
  },
  {
    concurrentParts: 2,
    waitTime: 10000,
    retries: 1,
    maxPartSize: 10 * 1024 * 1024
  }
);

uploader.on('data', function(bytesRead) {
  console.log(bytesRead, ' bytes read.');
});

uploader.on('part', function(number) {
  console.log('Part ', number, ' uploaded.');
});

// All parts uploaded, but upload not yet acknowledged.
uploader.on('uploaded', function(stats) {
  console.log('Upload stats: ', stats);
});

uploader.on('finished', function(resp, stats) {
  console.log('Upload finished: ', resp);
});

uploader.on('error', function(e) {
  console.log('Upload error: ', e);
});

uploader.begin(); // important if callback not provided.
