Question

I am using node.js with the express framework. As a session store I am using MongoDB. How can I set the lifetime after which the session objects are removed from MongoDB. This is how I am doing the declaration:

app.use(express.cookieParser());
    app.use(express.session({
                secret: "Stays my secret",
                store: new MongoStore({ db: 'myDB' })
                    }));

Your question is a little vague but from what i can gather you wan’t to set the expiration period for the session:

you can use maxAge like so:

app.use(express.cookieParser());
app.use(express.session({
    secret  : "Stays my secret",
    maxAge  : new Date(Date.now() + 3600000), //1 Hour
    expires : new Date(Date.now() + 3600000), //1 Hour
    store   : new MongoStore({ db: 'myDB' })
}));

expires value is required for new versions of express where as maxAge is for older versions, you should only need expires though.
