mpqjs

Library for reading MPQ (MoPaQ) archives in pure javascript, inspiration of mpyq, originally used for StarCraft II replay analyse.

Installation

npm install mpqjs --save

Usage

Initialize

const MPQArchive = require('mpqjs')
const archive = new MPQArchive('./tests/test1.SC2Replay')

Extract files to memory

archive.extract()

All files will be extracted to the memory, in a JSON object:

{
  'replay.attributes.events': <Buffer 00 00 00 00 00 8a 02 00 00 e7 03 ... >,
