unz

A lightweight package for reading ZIP files, using native Web APIs like ArrayBuffer and DecompressionStream. It's lightweight (about 2KB compressed) and works in all modern browsers, Node, and Deno, without any dependencies.

Usage

import unz from "unz";

// Log the file name and the first 10 bytes of every file in the ZIP archive.
const archive = unz(await file.arrayBuffer());
for (const [fileName, archiveFile] of archive) {
	console.log(fileName, new Uint8Array(await archiveFile.arrayBuffer(), 0, 10));
}
