Extract zip into folder node via express

I try to find example where I can send a zip (like via postman) and get this zip in my handler and unzip it so specified folder I didn't find much examples for zipping using express I want to unzip it in path web/app

I try something like the following which doesn't works for me , the zip file is not unzipped in the specified folder, any idea what im doing wrong ?

https://nodejs.org/api/zlib.html#zlib_zlib

var zlib = require('zlib');
var fs = require('fs');
const dir = path.join(__dirname, 'web/app/');

if (req.file.mimetype === 'application/zip') {

    var unzip = zlib.createUnzip();

    var read = fs.createReadStream(req.file);
    var write = fs.createWriteStream(dir);
    //Transform stream which is unzipping the zipped file
    read.pipe(unzip).pipe(write);   
    console.log("unZipped Successfully");

}

Any working example will be very helpful, or reference where can I've problem...

while debug I see the that this is when the code failed

var read = fs.createReadStream(req.file);

any idea why?

I've also tried with

var read = fs.createReadStream(req.file.body);

the issue that I dont see the error, reason etc.

when I change it to

var read = fs.createReadStream(req.file.buffer);

the program doesnt exit and i was able to run it until the logger console.log("unZipped Successfully"); but nothing happen...

if there any example with https://www.npmjs.com/package/yauzl yauzl and multer in my context it will be great
