Command for create zip archive without gem's 📁

class CreateZipCommand
  def call(files)
    # Create temp directory for files 
    tmp_dir = Dir.mktmpdir
    tmp_zip_path = File.join(tmp_dir, "files.zip")

    # Move files to the temporary folder you created above
    files.map do |file|
      download_file(file, tmp_dir)
    end

    # Go to the folder and archive the entire contents
    `cd #{tmp_dir} && zip #{tmp_zip_path} ./*`

    # Return zip path
    tmp_zip_path
  end
end

> CreateZipCommand.new.call(files)
=> "/var/folders/bk/0c864z710654sx555jpdpx9c0000gn/T/d20190126-7447-d27fpl/files.zip")

Most gems for working with archives eat a lot of memory when working with large files. This solution does not have these problems.

Make sure that the zip utility is installed on your computer - it don't work without it
