I have the following in my node js file

var express = require('express');

var util = require('./lib/utility');

var partials = require('express-partials');

var bodyParser = require('body-parser');



var session = require('express-session');



/* abstracted some code */



app.use(session({

  genid: function(req) {

    return genuuid(); // use UUIDs for session IDs

  },

  secret: 'keyboard cat'

}));

When I start the server, I get

express-session deprecated undefined resave option; provide resave option server.js

express-session deprecated undefined saveUninitialized option; provide saveUninitialized option server.js

I am having a hard time figuring out what is deprecated? I copied the example from https://github.com/expressjs/session

When I try to load the page I get:

ReferenceError: genuuid is not defined at app.use.session.genid
