How to zip a directory, recursively, without getting malformed files when you try to unzip in node.js -

so far have tried adm-zip , easy-zip. both of them create zip successful has malformed files:

this happens variety of file types (including regular pictures , html pages). suspect file type isn't issue. either way, can't use if doesn't work perfectly.

some people have suggested node-archive there no instructions how zip file, let alone recursively zip directory while keeping file structure.

update

as requested here code using (adm-zip)

var zip = require("adm-zip"); var zip = new zip(); zip.addlocalfolder("c:\\test"); zip.writezip("c:\\test\\color.zip"); 

as had mentioned, use node-archiver. can nested folders node-archiver by:

var archiver = require('archiver');  var archive = archiver('zip')  // create file writestream - let's call writestream  archive.pipe(writestream);  // subfiles/folders given folder - can done readdir // take @ http://nodejs.org/api/fs.html#fs_fs_readdir_path_callback // , https://stackoverflow.com/questions/5827612/node-js-fs-readdir-recursive-directory-search // appending archiver name has slashes in treat payload subfolder/file  // iterate through files previous walk iterate_through_results_from_walk     // http://nodejs.org/api/fs.html#fs_fs_readfile_filename_options_callback     get_read_stream_on_file_from_fs         archive.append((new buffer(data), 'utf-8'), {name: name_with_slashes_for_path});  archive.finalize(function (err) {     // handle error if there 1 }); 

hopefully pretty nudge in right direction (basically of steps there you). if isn't clear yet:

1. create archive 'zip' option.
2. pipe writestream created want save zip file.
3. walk through folder recursively, saving paths in collection (array) go along.
4. iterate through collection of paths, opening each file.
5. when have data of each file, create buffer , pass path archive.append.
6. call archive.finalize.

for sake of readability, , because believe have given pretty steps need, did not include of code (most notably walk - laid out in link anyhow).
