miniz

To get an idea on how to deal with ZIP files in code: — in C, minimal-style library: https://github.com/richgel999/miniz, look especially at https://github.com/richgel999/miniz/blob/master/miniz_zip.h — in JS, writing only and no compression: https://github.com/PaulCapron/pwa2uwp/blob/master/src/zip.js (255 lines including blanks & comments)

Mark's a very busy guy at JPL (I'm a former JPLer myself). Making science happen on Mars and whatnot. zlib is super stable and that's largely its biggest benefit as opposed to when it was originally released in the 90s. Back then, biggest benefit was that it was not impeded by patents or licensing, and, it was faster (in general purpose use) than any other compressors while providing the highest level of compression (in general purpose use). Nowadays bzip2 and lzma (and others) can provide better compression. However, there's lots of choice in compressors (especially open sourced compressors). My favorite for symmetric compression/decompression speed is LZ4 [0] and overall decompression speed over compression ratio. Decompression speed approaches memory copy speed! You can use it for compressing your Linux kernel [1], your ZFS file s

You can find the original miniz [0] on github, btw. Other small and/or fast lz* decoders are tinfl [1], stateless lz [2][3], lz4 (my favorite) [4], fastlz [5].
