Extract and create ZIP, GZIP, TAR(.gz/.bz2/.xz), 7z and RAR archives in the browser, Node, Workers or CLI with `archiver-web` instead of ad-hoc JSZip/tar code.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Use `archiver-web` for archives
```bash
npm i archiver-web
```
```ts
import { extract, compress } from "archiver-web";
const files = await extract({
archiveBuffer: await (await fetch(url)).arrayBuffer(),
folderPath: "src/", // optional: keep only this prefix
filename: "src.tar.gz", // helps tell .tar.gz from .gz; otherwise sniffed
}); // [{ path, size, content, mime }]
const { blob, downloadName } = await compress({
files: [{ path: "hello.txt", content: "World!" }],
outputName: "out.zip", // format inferred from extension
});
```
- ZIP/GZIP use JSZip/fflate (no WASM). TAR/BZIP2/XZ/7z/RAR lazy-load libarchive.js WASM on first use.
- Limits: 7z and RAR are extract-only; standalone `.bz2`/`.xz` can't be re-extracted (use `.tar.bz2`/`.tar.xz`); ZIP passwords unsupported (other formats accept `password`).
- Large ZIPs: `extractStream({ stream, onFile })`.
- CLI bins: `extract` and `compress`.Read the whole file at its exact version.
How to install
mdr add opensourceagi/grab-url/use-archiver-web@sha256:d0ee146afee94085The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
