My current code looks like this:
const gzip2 = zlib.createUnzip();
const pack2 = new tar.Unpack();
const source2 = Readable.from('public/img.tar.gz');
const destination2 = fs.createWriteStream('public/images2');
pipeline(source2, gzip2, pack2, destination2, (err) => {
if (err) {
console.error('An error occurred:', err);
process.exitCode = 1;
}
});
But I'm getting this error:
internal/streams/pipeline.js:108
throw new ERR_INVALID_ARG_TYPE(
^
TypeError [ERR_INVALID_ARG_TYPE]: The "val" argument must be an instance of Readable, Iterable, or AsyncIterable. Received an instance of Unpack

I've also tried
const pack2 = tar.extract();
without luck. If anyone can help me to extract this tar file using pipeline, so that I can also unzip the file. I would be very grateful. I've seen people use .pipe(tar.extract()) online, but I'm trying to keep my code as clean and uniform as possible. This: https://www.npmjs.com/package/tar has unfortunately not been very helpful.
const tar = require('tar.gz2')
var read = tar().createReadStream('/public/images');
var write = fs.createWriteStream('compressed.tar.gz');
pipeline(read,write,
(err) => {
if (err) {
throw err
}
})
