Description

Goal

Wasm component to handle basic archive creation and extraction. No arbitrary file I/O — operate entirely on byte arrays in and out.

Scope/Features

  • zip, tar, and gzip extraction of bytes to files (bytes in, file map out)
  • Creation of archives from input files (file map in, blob out)
  • Preserve file names, permissions when possible

Rough WIT shape

  • extract(input: list<u8>) -> result<file_map, error>
  • create(files: file_map) -> result<list<u8>, error>

Candidate crates

Labels

  • good first issue

Contributor guide

Research direction
Study the WIT interface and implement the extract and create functions using zip rs, tar, and flate2 crates. Focus on mapping bytes to file maps and vice versa.
