7-Zip compiled to WASM with emscripten. Based on 7-Zip 22.01 (2022-07-15).
- Runs in any JavaScript environment that supports WASM (Browser or NodeJS)
- Supports all file formats that the full
7zzCLI supports. - Only Emscripten NODEFS and WORKERFS adapters are included by default.

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