Replace bodyparser with formidable or multer

I'm testing with Nodecellar RethinkDB example app. While trying to replace body-parser For formidable or multer the app stop parsing data. So the problem i think It's inside the wines.js file.

that Is using body-parser variables to make the request's to RethinkDB. So can you tell me the chances i should make to use formidable or multer, Thanks.
