@rakered/swift

A library that helps to manage file uploads to OpenStack Swift based object storage, using Temp URL keys as authentication method.

Usage

import swift from '@rakered/swift';

await swift.upload({
  container: 'uploads',
  object: 'backup.zip',
  data: fs.createReadStream('~/backup.zip'),
  headers: {
    'content-type': 'application/zip',
  },
});

Methods:

upload(options)

Upload a file to the object store

options

• container String

  The container where the object should be stored

• object String

  The name of the object

• data Buffer/FileStream

  The file that should be stored. Can be any data format compatible with axios.

• headers Headers

  Headers to send along. content-type is a required header, but any header compatible with swift can be included.

• example

  import swift from '@rakered/swift';
  
  await swift.upload({
    container: 'uploads',
    object: 'backup.zip',
    data: fs.createReadStream('~/backup.zip'),
    headers: {
      'content-type': 'application/zip',
    },
  });
  

delete(options)

Delete a file from the object store

options

• container String

  The container where the object should be stored

• object String

  The name of the object

• example

  import swift from '@rakered/swift';
  
  await swift.delete({
    container: 'uploads',
    object: 'backup.zip',
  });
  

getDownloadUrl(options)

This library doesn't have a method to download the file. Instead, it provides a way to get an expiring download url.

options

• container String

  The container where the object should be stored

• object String

  The name of the object

• expires Number

  Optional - The number of seconds after which the download url stops working. Defaults to 300 sec (5 minutes).

• example

  import swift from '@rakered/swift';
  
  await swift.getDownloadUrl({
    container: 'uploads',
    object: 'backup.zip',
    expires: 300,
  });
  

Alternatives

This library only offers a limited set of methods, and there are alternatives available. I just needed something small, and something that uses temp url keys to authenticate, instead of logging in with username + password.

Alternatives:

• openstack-swift-client
• swift
