7-Zip WASM

7-Zip compiled to WASM with emscripten. Based on 7-Zip 24.09 (2024-11-29).

Runs in any JavaScript environment that supports WASM (Browser or NodeJS)
Supports all file formats that the full 7zz CLI supports.
Only Emscripten NODEFS and WORKERFS adapters are included by default.

Inspired by https://github.com/sonictruth/7zip.js

Usage

Command-line

npx 7z-wasm --help

npm i -g 7z-wasm
7z-wasm --help

As a module

import SevenZip from "7z-wasm";

const sevenZip = await SevenZip();

const archiveData = new Uint8Array(100);
const archiveName = "archive.7z";

const stream = sevenZip.FS.open(archiveName, "w+");
sevenZip.FS.write(stream, archiveData, 0, archiveData.length);
sevenZip.FS.close(stream);

const filesToExtract = ["some-file.txt"];
sevenZip.callMain(["x", archiveName, ...filesToExtract]);
console.log(sevenZip.FS.readFile(filesToExtract[0]));

Working with the real file system (Node.JS only)

import SevenZip from "7z-wasm";

const mountRoot = "/nodefs";
sevenZip.FS.mkdir(mountRoot);
sevenZip.FS.mount(sevenZip.NODEFS, { root: "/real/root/folder" }, mountRoot);
sevenZip.FS.chdir(mountRoot + "/subfolder");

sevenZip.callMain(["x", "archive.7z", "some-file.txt"]);

Building

Because the 7-Zip sources are not available on GitHub, the build process relies on downloading the sources from the 7-Zip website and patching them so they compile with emcc.

Install docker
Execute ./build (or .\build, respectively, on Windows CMD)

You can pass custom options to emcc via env file (e.g. see build-umd.env)
