Zstream

Build Status Hex.pm

An elixir library to read and write ZIP file in a streaming fashion. It could consume data from any stream and write to any stream with constant memory overhead

Example

Zstream.zip([
  Zstream.entry("report.csv", Stream.map(records, &CSV.dump/1)),
  Zstream.entry("catfilm.mp4", File.stream!("/catfilm.mp4", [], 512), coder: Zstream.Coder.Stored)
])
|> Stream.into(File.stream!("/archive.zip"))
|> Stream.run
File.stream!("archive.zip", [], 512)
|> Zstream.unzip()
|> Enum.reduce(%{}, fn
  {:entry, %Zstream.Entry{name: file_name} = entry}, state -> state
  {:data, data}, state -> state
  {:data, :eof}, state -> state
end)
