S3 Streaming Upload

s3-streaming-upload

s3-streaming-upload is node.js library that listens to your stream and upload its data to Amazon S3 and OCI Bucket Store.

It is heavily inspired by knox-mpu, but unlike it, it does not buffer data to disk and is build on top of official AWS SDK instead of knox.

Changes

• Version 0.3.2 NodeJS 12+ supported.

• Version 0.3.x Change from Coffee-script to Javascript. NodeJS 6 and 8 supported.

• Version 0.2.x using ManagedUpload API. NodeJS 0.10 and 0.12 supported.

• Version 0.1.x using MultiPartUpload API. NodeJS 0.8 and 0.10 supported.

Installation

Installation is done via NPM, by running npm install s3-streaming-upload

Features

• Super easy to use
• No need to know data size beforehand
• Stream is buffered up to specified size (default 5MBs) and then uploaded to S3
• Segments are not written to disk and memory is freed as soon as possible after upload
• Uploading is asynchronous
• You can react to upload status through events

Quick example

var Uploader = require('s3-streaming-upload').Uploader,
  upload = null,
  stream = require('fs').createReadStream('/etc/resolv.conf');

upload = new Uploader({
  // credentials to access AWS
  accessKey: process.env.AWS_S3_ACCESS_KEY,
  secretKey: process.env.AWS_S3_SECRET_KEY,
  bucket: process.env.AWS_S3_TEST_BUCKET,
  objectName: 'myUploadedFile',
  stream: stream,
  debug: true,
});

upload.send(function(err) {
  if (err) {
    console.error('Upload error' + err);
  }
});

Setting up ACL

Pass it in objectParams to the Uploader:

upload = new Uploader({
  // credentials to access AWS
  accessKey: process.env.AWS_API_KEY,
  secretKey: process.env.AWS_SECRET,
  bucket: process.env.AWS_S3_TRAFFIC_BACKUP_BUCKET,
  objectName: 'myUploadedFile',
  stream: stream,
  objectParams: {
    ACL: 'public-read',
  },
});

Example usage with Oracle Cloud (OCI) compatible S3 API

region = process.env.OCI_REGION;
tenancy = process.env.OCI_TENANCY;
// define custom service
service = new aws.S3({
  apiVersion: '2006-03-01',
  credentials: {
    accessKeyId: process.env.BUCKET_ACCESS_KEY,
    secretAccessKey: process.env.BUCKET_SECRET_KEY,
  },
  params: { Bucket: process.env.BUCKET_NAME },
  endpoint: `${tenancy}.compat.objectstorage.${region}.oraclecloud.com`,
  region: region,
  signatureVersion: 'v4',
  s3ForcePathStyle: true,
});

uploader = new Uploader({
  accessKey: process.env.BUCKET_ACCESS_KEY,
  secretKey: process.env.BUCKET_SECRET_KEY,
  bucket: process.env.BUCKET_NAME,
  objectName: filename,
  stream: source,
  service: service,
  objectParams: {
    ContentType: 'text/csv',
  },
  debug: true,
});
