Python function to construct a ZIP archive with stream processing - without having to store the entire ZIP in memory or disk

stream-zip

Python function to construct a ZIP archive on the fly - without having to store the entire ZIP in memory or disk. This is useful in memory-constrained environments, or when you would like to start returning compressed data before you've even retrieved all the uncompressed data. Generating ZIPs on-demand in a web server is a typical use case for stream-zip.

Offers similar functionality to zipfly, but with a different API, and does not use Python's zipfile module under the hood. Creates both Zip32/2.0/Legacy and Zip64 files.

To unZIP files on the fly try stream-unzip.

Features

In addition to being memory efficient (with some limitations) stream-zip:

• Constructs ZIP files that can be stream unzipped, for example by stream-unzip

• Can construct Zip64 ZIP files. Zip64 ZIP files allow sizes far beyond the approximate 4GiB limit of the original ZIP format

• Can construct ZIP files that contain symbolic links

• Can construct ZIP files that contain directories, including empty directories

• Can construct password protected / AES-256 encrypted ZIP files adhering to the WinZip AE-2 specification.

• Allows the specification of permissions on the member files and directories (although not all clients respect them)

• By default stores modification time as an extended timestamp. An extended timestamp is a more accurate timestamp than the original ZIP format allows

• Provides an async interface (that uses threads under the hood)
