title: Node/Multer Get Filename
body: <p>I am using the following to upload files to a directory via Multer. It works great, but I need to perform some actions after upload that require the name of the file I just posted to the "upload" directory. How do I get the name of the file I just posted?</p>
  
  <pre><code>// Multer storage options
  var storage = multer.diskStorage({
    destination: function(req, file, cb) {
      cb(null, 'upload/');
    },
    filename: function(req, file, cb) {
      cb(null, file.originalname + '-' + Date.now() + '.pdf');
    }
  });
  
  var upload = multer({ storage: storage });
  
  app.post('/multer', upload.single('file'), function(req, res) {
    // Need full filename created here
  });
  </code></pre>
