Hey there!

node_zip.js

// npm packages for zip:
// zip: 202 days
// adm-zip: 41 days
// zip-utils: 4 days (0.0.1) [repo no longer exists]
// zipper: 96 days
// zipper-insane: 136 days
// node-native-zip: 2w (1.1.0)
// node-zip: 2 days (0.0.1)
// zippy: 223 days

// CANDATES ARE: node-native-zip, node-zip
/*
 * node-native-zip: https://github.com/janjongboom/node-native-zip
 * - Only supports write, no read (acceptable)
 * - Only supports STORE, no compression 
 *   (unacceptable; some Android APK files require DEFLATE)
 *
 * REJECTED
 */
 
/*
 * node-zip: https://github.com/daraosn/node-zip (MIT license)
 * requires: node.js fs (Stable: 3) mv (Stable: 3)
 * - Depends upon JSZip (http://stuartk.com/jszip/)
 * - JSZip is: 5m old, GPLv3 and/or MIT (???), supports zip+unzip
 * - Unlikely to ever be updated
 * - Incomplete documentation (for JSZip)
 * - HAS CRITICAL IMPLEMENTATION BUG:
 * generate()d zipfiles lack end-of-dir signature
 *
 * REJECTED - THIS SAMPLE CODE DEMONSTRATES IMPLEMENTATION BUG.
 * Just try and unzip the resulting zipfile.
