This is actually easy:

  let remotePath = 'some/key/to/store.json';
  let localReadStream = new stream.PassThrough();
  localReadStream.end(JSON.stringify(someObject, null, '   '));

  let remoteWriteStream = bucket.file(remotePath).createWriteStream({ 
     metadata : { 
        contentType : 'application/json' 
     }
  });

  localReadStream.pipe(remoteWriteStream)
  .on('error', err => {
     return callback(err);      
  })
  .on('finish', () => {
     return callback();
  });
