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.

Defaults and Configurables

• concurrentParts (Default: 5) - Parts that are uploaded simultaneously.
• waitTime (Default: 1 Min) - Time to wait for acknowledgement from S3 after uploading a part in ms, use 0 for forever.
• retries (Default: 5) - Number of times to retry uploading a part, before failing.
• maxPartSize (Default: 5 MB) - Maximum size of each part in bytes.

Statistics object

• downloadTime - Download time in seconds. (Reading from stream)
• downloadSpeed - Download speed in bytes/second.
• uploadTime - Upload time in seconds.
• uploadSpeed - Upload speed in bytes/second. (Streaming to S3)
• size - Total bytes uploaded.
