Untarjs

Fetching and unpacking archives. This package uses compiled libarchive into wasm and supports: tar, bzip2, zstd, zlib, zip, ustar, pax, v7, gnutar, cpio, mtree.

> Note: To add the support of another archive format, libarchive should be compiled again with --with-[name-archive-lib] into wasm here Libarchive recipe and then run yarn run build in this project to make new unpack.js and unpack.wasm files.

Using

This package has 2 methods:
- extract(url) - downloads an archive through the url and returns extracted data as an object representing the file structure:
``
{
"file1": Uint8Array
"info/paths.json": Uint8Array,
...
}
`
- exctractData(data) - accepts Uint8Array archive data and returns exracted data in the same format which extract method does.

The example of using:
`sh
import { initUntarJS } from "@emscripten-forge/untarjs";

const untarjs = await initUntarJS();

const condaPackageUrl = 'https://conda.anaconda.org/conda-forge/linux-64/_libgcc_mutex-0.1-conda_forge.tar.bz2';
untarjs.extract(condaPackageUrl).then((files)=>{
console.log(files);
});
