node-archiver : Getting duplicate parent zip upon extracting

Question

I have written below for zipping a directory :

const archiver = require('archiver');
let createArchive = function(sourceDir, destDir) {
    const archive = archiver('zip');
    const stream = fs.createWriteStream(destDir);
    return new Promise((resolve, reject) => {
    archive
      .directory(sourceDir, false)
      .on('error', err => reject(err))
      .pipe(stream)
    ;

    stream.on('close', () => resolve());
    archive.finalize();
  });
}

Before zipping my directory looked like this :

• excelArchive.zip
• test.txt
• test2.gz

When I unzipped the archive (called yayy.zip) it had these files in it:

• excelArchive.zip
• test.txt
• test2.gz
• yayy.zip

There is an invalid file called yayy.zip inside it. How can I avoid this?

Instead of directory, you can use the glob method to specify the files to zip. It takes a second argument where you can specify files to ignore.

const archiver = require('archiver');
let createArchive = function(sourceDir, destDir) {
    const archive = archiver('zip');
    const stream = fs.createWriteStream(destDir);
    return new Promise((resolve, reject) => {
    archive
      .on('error', err => reject(err))
      .pipe(stream)
      .glob(
        '**/*',
        {cwd: sourceDir, ignore: filename}
      )
    ;

    stream.on('close', () => resolve());
    archive.finalize();
  });
}
