Description

A service for zipping and downloading a group of files with a common directory on the same machine as the service is running. Authorization is based on the properties username:string groups:string[] in the JWT.

Install

docker-compose up or npm install && npm start

Usage

zip with download

Zip requests are sent as POST to /zip, which redirect to a download progress page. The post body should have the following format:

data: {
  "jwt": "token",
  "directory": "/path/to/files",
  "files": ["file1","file2","file3"]
}

/zip shows a page with a progress bar, resulting in a downloadable zip-file.

zip in place

While zip with download is a two step process (the file is zipped to a temporary directory on the server and then downloaded from the browser), another route, /zip_in_place exists which zips the payload in the same time as downloading.
