Re: ZIP archive API?

I'm interested a JS API that does the following:

- Receive an archive from a Dataurl, Blob, URL object, File (as in
filesystem API) or Arraybuffer
- List its content and metadata
- Unpack members to Dataurl, Blob, URL object, File or Arraybuffer

- Create an archive
- Put in members passing a Dataurl, Blob, URL object, File or Arraybuffer
- Serialize archive to Dataurl, Blob, URL object, File or Arraybuffer

To avoid the whole worker/proxy thing and to allow authors to selectively
choose how they want to handle the data, I'd like to see synchronous and
asynchronous versions of each. I'd make synchronicity an argument/flag or
something to avoid API clutter like packSync, packAsync, writeSync,
writeAsync, and rather like write(data, callback|boolean).

- Pythons zipfile API is ok, except the getinfo/setinfo stuff is a bit over
the top:
- Pythons tarfile API is less clutered and easier to use:
- zip.js isn't really usable as it doesn't support the full range of types
(Dataurl, Blob, URL object, File or Arraybuffer) and for asynchronous
operation needs to rely on a worker, which is bothersome to setup:

My own implementation of the tar format only targets array buffers and
works synchronously, as in.

var archive = new TarFile(arraybuffer);
var memberArrayBuffer = archive.get('filename');
