alt Hacker NewsHey, this is also my interest. I was just looking into whether it was possible to e.g. build an archive extractor that runs like a normal program but does the actual extraction completely in wasm. Unfortunately, AFAICT it's possible but requires custom code; you can't (yet, I hope) just compile unzip/libarchive/whatever with CC=wasicompiler and get a sandboxed binary. But we're getting close.

You should be able to do exactly that though? Why do you think you can't?
You will of course need to include a lot of support code to provide the relevant syscalls and otherwise emulate the environment that the code expects. But there are plenty of examples of that at this point.
What do you mean? You absolutely can run compression in WASM.
For example here is Gzip in WASM: https://github.com/ColinTimBarndt/wasm-gzip
