How can I compress/decompress a buffer via yazl? https://www.npmjs.com/package/yazl

I don't want to create/save a zip file but just compress a buffer and forward it to another service. Any sample code would be helpful

This kind of function should help, manually retrieving the stream's packets, then concatenating them into one single Buffer:

QUESTION

Create zip archive larger than 4 GiB that can be opened via MacOS Archive Utility

Asked 2017-May-21 at 17:38

I am trying to generate large zip file (without compression, just storing the files) on the fly and stream it via restify. The zip file can be bigger than 4 GiB in total and I ran to issue with ZIP64 format, that seems not to be supported properly on MacOS.

I tried using node-archiver and yazl, they are both able to generate the zip file, but I am not able to open it via native graphical utility in MacOS (e.g. just double-clicking on the file in Finder). The weirdest thing about this is, that the native unzip command line utility works fine here, just the graphical Archive Utility is not working.

I also tried to create the zip using simple java implementation and the resulting file works ok even with the graphical Archive Utility, so the problem is probably in implementation of node-archiver/yazl libraries. I also tried to create the zip via command line (zip file.zip -0 ...files), and it can also be opened via Archive Utility.

What is the correct way to handle this situation? Is there some other node library that can produce ZIP64 format that can be opened via Archive Utility?

It is necessary to stream the zip file, not storing it on disk. I am running latest version of MacOS sierra (10.12.5 beta) and node 6.9.1.

If anyone struggles with the same requirements as I did, check JSZip library (https://stuk.github.io/jszip/). It can also work with node streams and is able to produce zip files larger than 4 GiB, that can be opened via MacOS Archive Utility. The only limitation of this is, that you can not have a file larger than 4 GiB, because of 32 bit CRC32 hash generation (but the zip file can be larger).

Here is a snippet of how you can use this library:

Install yazl

You can install using 'npm i yazl' or download it from GitHub, npm.

Support

yazl automatically uses ZIP64 format to support files and archives over 2^32 - 2 bytes (~4GB) in size and to support archives with more than 2^16 - 2 (65534) files. (See the forceZip64Format option in the API above for more control over this behavior.) ZIP64 format is necessary to exceed the limits inherent in the original zip file format. ZIP64 format is supported by most popular zipfile readers, but not by all of them. Notably, the Mac Archive Utility does not understand ZIP64 format (as of writing this), and will behave very strangely when presented with such an archive.
