Adm Zip zipping files as directories

Question

I am trying to pack files into a zip file using Adm-Zip

var AdmZip = require('adm-zip');

var pathToZip = 'build/release/Ext.zip';


var zip = new AdmZip();

zip.addLocalFile('background.js');
zip.addLocalFile('chrome_ex_oauth.html');
zip.addLocalFolder('images');
zip.writeZip(pathToZip);

However, all the files are getting added as folders inside the zip and the actual content is not getting zipped.

The Getting Started reference is below and this seems to be a very simple example which is not working as expected. What am I doing wrong? https://github.com/cthackers/adm-zip/wiki/ADM-ZIP-Introduction

Answer 1

So I did some digging: https://github.com/cthackers/adm-zip/blob/master/adm-zip.js#L275

addFile is ultimately called by addLocalFile, and that seems to be where the error is occurring, specifically on line 281 where it checks if the ZipEntry is a directory. The wrong flags are getting applied.

To get around this, I ended up calling addFile manually and specified the attributes myself, so that it wouldn't rely on auto-detection and incorrectly flag files as directories.

addFile(filePathInArchive, fileBuffer, '', 0644 << 16);

To get a fileBuffer yourself, you can use fs.readFile or fs.readFileSync
