hi

can you please add a example on how to extract a specific folder ?
thanks in advance for your help

download('urltofile').pipe(unzipper.Parse()).on('entry', function (entry)
{
	var fileName = entry.path;
	var type = entry.type;
	var size = entry.size;

	if (type === 'Directory' && /src\/assets\/scss/i.test(fileName))
	{
	    //extract this folder
	}
	else
	{
	    entry.autodrain();
	}
});

Every entry has the full path of the filename in the entry.path. So you can pick your files with something like this:

var Writer = require('fstream').Writer;

download('urltofile').pipe(unzipper.Parse()).on('entry', function (entry) {
  // filename will be undefined if it doesn't match the regex
  var filename = /src\/assets\/scss\/(.*)/i.exec(entry.path);
  if (type != 'Directory' && filename) {
    entry.pipe(writer({path: filename[1]}));
  } else {
    entry.autodrain();
  }
});

If the incoming zip files are untrusted you also might want to protect against extracting files above the target directory by adding a check like this:

    // to avoid zip slip (writing outside of the destination), we resolve
    // the target path, and make sure it's nested in the intended
    // destination, or not extract it otherwise.
    var extractPath = path.join(opts.path, entry.path);
    if (extractPath.indexOf(opts.path) != 0) {
      entry.autodrain();
      return;
    }

Please reopen if this doesn't work or if you have any questions/comments!
