NodeJS Mongoose connect-mongo Session Storage with Mongo - node.js

Question

I try to configure my connect-mongo in the way I can use session in nodejs that is persisted with mongo. I use following code
var mongoose = require('mongoose');
function connect(url, callback) {
mongoose.connect(url);
var connection = mongoose.connection;
connection.on('error', console.error.bind(console, 'connection error:'));
connection.once('open', function() {
console.log("Mongoose connected at: ", url);
callback(connection);
});
}
var express = require("express");
var body_parser = require('body-parser');
var cookie_parser = require('cookie-parser');
var hogan_express = require('hogan-express');
var session = require('express-session');
var mongo_store = require('connect-mongo')(session);
var express = require("express");
var app = express();
app.engine('html', hogan_express);
app.set('view engine', 'html');
app.set("views", "views");
app.use("/libs", express.static("bower_components"));
if (!config.development) {
app.use(express.static("min"));
}
app.use(express.static("public"));
connect("MONGODBURL",function(mongoose_connection){
app.use(body_parser.json());
app.use(cookie_parser());
app.use(session({
secret: "asd",
store: new mongo_store({
mongoose_connection: mongoose_connection
// db: mongoose_connection.db
})
}));
})
I have tried everything but executing some code I have never the object session in my res refrence.
Getting: TypeError: Cannot set property 'asd' of undefined
Code:
app.get("/rest/test",function(req, res) {
req.session.asd="test";
res.send(req.session.asd)
});
Somone could give a hint for a solution?

You need to define your routes after your configure your session.
...
app.use(session....
...
app.get("/...
Inside your connect's callback in your case. Probably start listening inside it only as well.
connect("MONGODBURL",function(mongoose_connection){
app.use(body_parser.json());
app.use(cookie_parser());
app.use(session({
secret: "asd",
store: new mongo_store({
mongoose_connection: mongoose_connection
// db: mongoose_connection.db
})
}));
app.get("/rest/test",function(req, res) {
req.session.asd="test";
res.send(req.session.asd)
});
app.listen(...
});
