Javascript Question

how to use connect-orientdb module with express

My goal is to connect my server code that its with nodejs and expressjs framework to my database that is with orientdb.
first of all i wanted to store my sessions in database. but i had difficulty connecting my server to database.

the error that i get when i execute server.js:

/Users/soroush/Desktop/nodeOrient/node_modules/connect-orientdb/lib/connect-orientdb.coffee:191
})(connect.session.Store);
^

TypeError: Cannot read property 'Store' of undefined
at module.exports (/Users/soroush/Desktop/nodeOrient/node_modules/connect-orientdb/lib/connect-orientdb.coffee:22:46)

at Function.Module.runMain (module.js:575:10)
at startup (node.js:160:18)
at node.js:449:3


and my server.js code is:

var express = require('express'),
cs = require("coffee-script/register"),
app = express(),
path = require('path'),
cookieParser = require('cookie-parser'),
session = require('express-session'),
config = require('./config/config.js'),
orientDBStore = require('connect-orientdb')(session),
OrientDB = require('orientjs'),
orientDBConfig = {
server : {
host: "localhost",
port:2424
},
db : {
user_name: "admin",
user_password: "admin"
},
database : "sessions",
class_name : "sessions_class"
},
server = OrientDB({
hose : "localhost",
port : "2424",
username : "root",
password : "root"
})
;

app.set('views', path.join(__dirname, 'views'));
app.engine('html', require('hogan-express'));
app.set('view engine', 'html');
app.use(express.static(path.join(__dirname,'public' )));

app.use(cookieParser());

require('./routes/route.js')(express, app);

app.use(session({
secret:"mySecret",
store: new orientDBStore(orientDBConfig)
}));

app.listen(8000, function () {
console.log("app is listening on port 8000");
})


my main problem is that the connect-orientdb was used when the session module was builtin in express, but now that session is a different module i have occurred to this problem.

Answer

Finally i found a solution for it if anyone faced this problem:

var session = require('express-session'),
    OrientoStore = require('connect-oriento')(session);

app.use(session({
        secret: 'SomeSecret',
        store: new OrientoStore({
            server: "host=localhost&port=2424&username=dev&password=dev&db=test"
        })
    }));
