Multer GridFs Storage Associate req.user to metadata

I can upload a file to my MongoDB using multer-gridfs-storage, but I am having trouble associating the file with user, what i want is to be able to pass req.user which i get from passportjs to the file metadata

// Create mongo connection
const conn = mongoose.createConnection(mongoURI);


// Init gfs
let gfs;

conn.once('open', () => {
gfs = Grid(conn.db, mongoose.mongo);
gfs.collection('uploads');
});

// Create storage engine
const storage = new GridFsStorage({
  url: mongoURI,
  file: (req, file) => {
  crypto.randomBytes(16, (err, buf) => {
  if (err) {
        return reject(err);
      }
      const filename = buf.toString('hex') + 
      path.extname(file.originalname);
      const fileInfo = {
        filename: filename,
        bucketName: 'uploads',
        metadata: {
          user : // I want to pass here req.user 
        }
      };
      resolve(fileInfo);
    });
  });
},
});
const upload = multer({ storage });

You should implement like this:

// Create mongo connection
const conn = mongoose.createConnection(mongoURI);


// Init gfs
let gfs;

conn.once('open', () => {
gfs = Grid(conn.db, mongoose.mongo);
gfs.collection('uploads');
});

// Create storage engine
const storage = new GridFsStorage({
  url: mongoURI,
  file: (req, file) => {
  crypto.randomBytes(16, (err, buf) => {
  if (err) {
        return reject(err);
      }
      const filename = buf.toString('hex') + 
      path.extname(file.originalname);
      const user = req.user;
      const fileInfo = {
        filename: filename,
        bucketName: 'uploads',
        metadata: user
      };
      resolve(fileInfo);
    });
  });
},
});
const upload = multer({ storage });
