How to know when npm `unzip` module has finished unzipping file?

Question

I'm using the unzip module from npm to extract the contents of a zip archive. I need to know when it is done extracting and the file has been completely written to disk.

My code:

fs.createReadStream('master.zip').pipe(unzip.Extract({ path: 'gitdownloads/repo' }));

What I've tried:

My first thought was that I could tap into the stream and listen for the finish event, but unzip only takes input: it doesn't return another stream.

I also looked to see if the unzip module had a "finish" callback. No luck.

From the github README

Extract emits the 'close' event once the zip's contents have been fully extracted to disk.

You'll want to do something like:

fs.createReadStream('master.zip')
  .pipe(unzip.Extract({ path: 'gitdownloads/repo' }))
   .on('close', function () {
     ...
   });
