How to use the decompress.targz function in decompress

function (response) {
					var decompressor = new Decompress();
					decompressor.src(response.data)
						.use(Decompress.zip())
						.use(Decompress.targz())
						.dest(self.directory)
						.run(function (error) {
							if (error) {
								reject(error);
							}
							else {
								resolve();
							}
						});
				},
				function (error) {

var decompressOptions = { strip: 1, mode: '755' };
var filePath;
if( parsedUrl.protocol == 'file:' ) {
  filePath = path.resolve(
    decodeURIComponent(
      url.slice( 'file://'.length )
    )
  );
  if ( !fileExistsAndAvailable(filePath) ) logError(
    'Could not find ' + filePath
  );
  new Decompress()
    .src( filePath )
    .dest( dest )
    .use( Decompress.zip(decompressOptions) )
    .use( Decompress.targz(decompressOptions) )
