Is there a KMP library for reading zip file. Can we do it using kotlinx-io library ?

[Michael Paus]

Reading and writing would be nice but I don’t know of any working solution. I have been searching for that too for a while.

I'm wondering if okio can be used.

[Michael Paus]

Okio has support for it but not on all platforms. It only works on Java based platforms, so, e.g., it doesn’t work on iOS and web.

Ah interesting!

Learnt that we can use okio library for unpacking zip files. We can access FileSystem.SYSTEM from iosMain and androidMain but not commonMain.

See this:

Worked like a charm

I’ll give it a try whether unpacking works but here’s my question whether we can also create one:

Just published a lightweight library specifically for KMP ZIP handling:

Currently some targets are missing, but I am working on adding them. Also feel free to open PRs :)

Any plans for JS/Wasm?

I will look into it, but am of course open to any contributions
