console.log(folders); // ['my-folder/subfolder/subsub1/','my-folder/subfolder/subsub2/']

API

The s3ls accepts two options:

• bucket - Obligatory. The S3 bucket name
• s3 - Optional. The aws-sdk S3 class instance. For example: new AWS.S3({apiVersion: '2006-03-01'})

The s3ls.ls(path) function takes:

• path - any string. E.g.
  • "/", "", or
  • "/folder", "folder/", "folder", or
  • "/1/2/3/4", "1/2/3/4/", "1/2/3/4", etc.
