I used info from this thread but decided to post my end to end code because it includes all the elements to download a zip file generated by the backend server.

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. To unZIP files on the fly try stream-unzip. It's not possible to completely stream-write ZIP files. Small bits of metadata for each member file, such as its name, must be placed at the end of the ZIP. In order to do this, stream-zip buffers this metadata in memory until it can be output.

However in these cases the entire contents of each uncompressed file is buffered in memory, and so should not be used for large files. Hence the onus is on client code to choose. These limits apply to both the compressed and uncompressed sizes of each member file. ZipOverflowError also inherits from the OverflowError built-in.

The uncompressed size of a member file is too large. The compressed size of a member file is too large. The size of the central directory, a section at the end of the ZIP that lists all the member files. Too many entries in the central directory, a section at the end of the ZIP that lists all the member files.

The offset of data in the ZIP is too high, i. This can be raised when stream-zip adds member files, or when it adds the central directory at the end of the ZIP file.

It is possible for the ZIP file to be larger than the maximum allowed offset without this exception being thrown.
