Ability to specify path separator

[elijaholmos]

I'm using this library on my local Windows 10 device to programmatically zip up a directory of browser extension source files; a pretty simple operation. I ran into an interesting problem the other day: the browser store I was submitting my extension to did not support backslashes as the path separator for directories in zip files. A maintainer of the extension store's validation software confirmed that this was intentional, and advised that I either switch to a different zipping library, or find a way to implement the forwardslash separator with fflate. I briefly perused the documentation, but couldn't find anything that mentioned such an option.

Is this behavior currently possible with fflate? If not, may I submit a feature request?

fflate always adds forward slashes in ZIP files unless you manually use paths with backward slashes. Could you check if that's what's happening?

Just checked your code, you might want to use the object syntax instead of files to zip.

import { zipSync } from 'fflate';

zipSync({
  folder1:  {
    folder2: {
      // folder1/folder2/out.txt
      'out.txt': new Uint8Array([97])
    }
  }
})

that works, thank you. the filename approach didn't work because I was manually specifying paths?

Yeah, your path.relative call was returning a Windows path. fflate will take your filepath and add it to the ZIP, no questions asked; it won't convert it to Unix for you. You could possibly also have used path.posix.relative or something but using this directory structure is better because it also creates directory entries in the ZIP.

I see. thanks again for your help & explanation
