app[web.1]: (node:4) DeprecationWarning: `open()` is deprecated in 
mongoose >= 4.11.0, 
use `openUri()` instead, or set the `useMongoClient` option if using 
`connect()` 
or `createConnection()`. See 
http://mongoosejs.com/docs/connections.html#use-mongo-client
Db.prototype.authenticate method will no longer be available in the 
next major
release 3.x as MongoDB 3.6 will only allow auth against users in the 
admin db 
and will no longer allow multiple credentials on a socket. Please 
authenticate using MongoClient.connect with auth credentials.
