## Usage: Stream files from a bucket folder

```javascript

var s3Files = require('s3-files')

var region = 'bucket-region'
var bucket = 'name-of-s3-bucket'
var folder = 'name-of-bucket-folder/'
var file1 = 'Image A.png'
var file2 = 'Image B.png'
var file3 = 'Image C.png'
var file4 = 'Image D.png'

// Create a stream of keys.
var keyStream = s3Files
  .connect({
    region: region,
    bucket: bucket    
  })
  .createKeyStream(folder, [file1, file2, file3, file4])

// Stream the files.
s3Files.createFileStream(keyStream)
  .on('data', function (chunk) {
    console.log(chunk.path, chunk.data.length)
  })
```

## Usage: Stream files from the root of a bucket

```javascript

var s3Files = require('s3-files')

var region = 'bucket-region'
var bucket = 'name-of-s3-bucket'
var folder = ''
var file1 = 'Image A.png'
var file2 = 'Image B.png'
var file3 = 'Image C.png'
var file4 = 'Image D.png'

// Create a stream of keys.
var keyStream = s3Files
  .connect({
    region: region,
    bucket: bucket    
  })
  .createKeyStream(folder, [file1, file2, file3, file4])

// Stream the files.
s3Files.createFileStream(keyStream)
  .on('data', function (chunk) {
    console.log(chunk.path, chunk.data.length)
  })
```
