What Hacker News says
4 sourcesHaving browsed through a few different zip parsers in the course of writing my own, most handle a range of malformed/modified input, including prepended/appended garbage, filename encodings (CP437, Unicode "extra field" flags), etc. I found this set of test files useful: https://github.com/Stuk/jszip/tree/master/test/ref
It is annoying that support for these non-standard zips has become de-facto standard (you don't want your tool to fail where others succeed)...
In The .zip file specification is flawedThanks for the mention but I only created JSZip[0], the library that powers the zip/unzip of js-xlsx[1], but not js-xlsx itself!

In Racking Mac ProsHi, I'm the author of JSZip. This sentence is kind of awkward. What I meant is that a lot of data is generated in the browser, and traditionally (at least at the time I wrote this library almost 5 years ago) this would involve sending the data back to your server to zip it up and send it back to the user for download. Instead this can all be done client side.
As an example, someone told me about a web app[1] which allows you to create an animated sprite offline. They use JSZip to let you download all the frames in one file.
There's actually an outstanding PR[2] to update the documentation that I still need to review, hopefully that makes things clearer.
