How would I unzip a zip file in node

I would like to unzip a .zip file in node without any external libraries. How would i go about doing this?

I have tried using zlib but it returns incorrect header type

let zipfile = fs.readFileSync(fileinfomation.savelocation)   
zlib.gunzipSync(zipfile)

Edit I have also tried using

let zipfile = fs.readFileSync(fileinfomation.savelocation)   
zlib.unzipSync(zipfile)

And it returned i caused the following error Uncaught Error Error: incorrect header check

zlib does not appear to support decompressing a whole zip file archive (that contains multiple files) which is what your visual studio zip file is.

You will either have to use a different library that does support decompressing zip archive files (there are many different libraries on NPM that support that) or you can use child_process to run a zip decompressor that is already on your system.

If this is windows, you can run (using child_process) the built in tar.exe that can decompress zip archive files or you can get your own command-line decompressor (I use 7-zip myself) and run it as a child_process.
