Openstack Swift storage

This library is a simple wrapper over pkgcloud to be able to use the Swift storage provider from Openstack easily.

A distributed object storage system designed to scale from a single machine to thousands of servers. Swift is optimized for multi-tenancy and high concurrency. Swift is ideal for backups, web and mobile content, and any other unstructured data that can grow without bound.

How to install it

• Install the package from npm with yarn add @adriantombu/openstack-swift
• Instanciate the library in your script

const swift = require('./lib').default.client({
  username: 'swift-username', // required
  password: 'swift-password', // required
  authUrl: 'swift-auth-url, // required
  region: 'swift-region'
  version: 'v3',
  keystoneAuthVersion: 'v3',
  domainName: 'Default'

Container Model

A Container for OpenStack has following properties:

{
  name: 'my-container',
  count: 1, // number of files in your container
  bytes: 12345, // size of the container in bytes
  metadata: { // key value pairs for the container
    // ...
  }
}

File Model

{
  name: 'my-file',
  container:  'my-container', // may be an instance of container if provided
  size: 12345, // size of the file in bytes
  contentType: 'plain/text' // Mime type for the file
  lastModified: Fri Dec 14 2012 10:16:50 GMT-0800 (PST), // Last modified date of the file
  etag: '1234567890abcdef', // MD5 sum of the file
  metadata: {} // optional object metadata
}
