xz-decoder-js

Pure JavaScript XZ decoder with no external dependencies.

xz-decoder-js is a lightweight JavaScript module that can decode .xz compressed data directly, without requiring any native bindings or external libraries.

This package is particularly useful in environments like Node.js where minimal dependencies and full portability are desired.

Features

• No dependencies
• Works in Node.js
• No need of WebAssembly
• Decodes .xz format (LZMA2 compression)
• Pure JavaScript implementation
• Based on a Dart port

Installation

npm install xz-decoder-js

Usage Example

import { XZDecoder } from 'xz-decoder-js';
import fs from 'fs';

const data = fs.readFileSync('file.xz');
const decoder = new XZDecoder();
const decoded = decoder.decodeBytes(data);
fs.writeFileSync('output.bin', decoded);

Credits

This project is based on the Dart archive package by Brendan Duncan, from which the core XZ decoding logic was adapted and ported to JavaScript.
