-Packers works in both a node and browser environment (Angular etc). Now, the packer returns a `Buffer`, `Blob`, `string`, `base64 string`, or `Stream`. It is up to you to take that and persist it with node's `fs`, send it down as a downloadable file, or anything else you wish. As of `version 4+`, this library will not have options to export to PDF.
