Zlib module

[KluVerKamp]

Is there any plans to create a module to zip/unzip files and folder?

deno_std refers to golang std to achieve.

So this should be part of the plan.

• deno_std/archive
  • tar
  • zip

If you or someone else is interested, welcome PR.

I have ported a simple JavaScript-based tar archiver to Deno during my effort to implement a web server.

There are multiple variations in tar format and it currently only supports USTAR but the other two popular formats (PAX and GNU). Still, could it be a small starting point? I could implement a bit more (e.g., Reader-based deflating method, GNU format support) and send a PR.

[Update] Now the implementation is updated to use reader/writer instead of just returning Uint8Array, allowing far more efficient memory use.

For my project I need to parse a gzip compressed http response, but sadly I found absolutely no way to complete this task in Deno even when allowing hacky solutions, zip is not implemented and I could not spawn a child process to use a external program either.

The nodejs method would be zlib.createGunzip()

Seeing how you wish to port the go std, this would be the one: https://github.com/golang/go/tree/master/src/archive/zip

I was working on the port of pako library which allows binary equal output as the famous zlib implementations, while it is still on its way.

Probably I can have some time to do the rest (provide an API on top of the pako port) by the end of this month, but if you are in a hurry, you can find a working prototype here in my fork:
