Error Zipping Folder with many files or sub folders

[chelinho139]

Hey, so I am trying to zip my DB backup, it has like 100.000 folders, and it throws an:
Error: EMFILE: too many open files

However, i am able to zip it manually using linux:
zip -r backupDB_2017-6-15.zip backupDB_2017-6-15

Hope someone can help me out...

This is the error stacktrace I get:

events.js:141
      throw er; // Unhandled 'error' event
      ^

Error: EMFILE: too many open files, scandir '/home/centos/server/backupDB_2017-6-14'

You can't get it in npm until @sole accepts the PR.

But you can use the below snippet to make it work

P.S: Install Archiver using npm install archiver

const fs = require('fs');
const archiver = require('archiver');
const zipFolder = (srcFolder, zipFilePath, callback) => {
var output = fs.createWriteStream(zipFilePath);
var zipArchive = archiver('zip');
output.on('close', function() {
callback();
});
zipArchive.pipe(output);
zipArchive.glob('**/*',
{ cwd: srcFolder,
src: ['**/*'],
expand: true }
);
zipArchive.finalize(function(err, bytes) {
if(err) {
callback(err);
}
});
}
