ZipStreamer

ZipStreamer is a Python library for generating ZIP files on-the-fly with ZIP file size information.

This library was implemented using logic from Python's zipfile library and Golang's archive/zip library.

z = ZipStream(files=[
    ZipFile('file.txt', 4, lambda: StringIO('test'), None, None),
    ZipFile('emptydir/', None, None, None, None),
    ZipFile('dir/remote.txt', remote_file_size, get_remote_file, None, None),
])

size = z.size()

res = Response(z.generate(), mimetype='application/zip')
res.headers['Content-Length'] = str(size)
