List contents of an S3 bucket 'folder'. Node.js module and command line executable.

npm i -S s3-ls

var s3ls = require('s3-ls');

var lister = s3ls({bucket: 'my-bucket-name'});

lister.ls('/my-folder/subfolder/')
.then((data) => {
  console.log(data.files); // ['my-folder/subfolder/file1','my-folder/subfolder/file2']
  console.log(data.folders); // ['my-folder/subfolder/subsub1/','my-folder/subfolder/subsub2/']
})
.catch(console.error);

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.

$ npm i -g s3-ls

Usage:

s3-ls BUCKET [PATH]

Example

$ s3-ls my-bucket-name my-folder/subfolder/
f1/
f2/
new folder/

• Node callbacks interface. No Promises. See README here.
• The optional aws-sdk dependency version was >=2.0.0 <3.0.0.

• Only promises are supported now. For node callbacks use s3ls.ls(path).then(r => cb(null, r), cb)
• The optional aws-sdk dependency version is >=2.3.0 <3.0.0 now.
