I am referring the following code to upload a file into Google Cloud Storage https://github.com/GoogleCloudPlatform/nodejs-getting-started/blob/master/3-binary-data/lib/images.js#L48

I was able to upload successfully, Now i am trying to add metadata to file so i have modified the code as below 

  const stream = file.createWriteStream({
    metadata: {
      contentType: req.file.mimetype,
      foo: 'bar'
    }
  });

But the foo=bar metadata is not getting attached to the file in Google Cloud Storage

If you want to attach metadata to file, then you need to keep that data under metadata. Change your code to the following 

const stream = file.createWriteStream({
    metadata: {
      contentType: req.file.mimetype,
      metadata: {
        foo: 'bar'
      }
    }
});
