In my projec

Answer 1

For the session management we need a middleware 'cookie-parser'.Previously it is the part of express but after express 4.0 and later it is a separate module.

So to access the cookie parser we need to install in our project as :

npm install cookie-parser --save

Then add this into your app.js file as :

var cookieParser = require('cookie-parser');

 app.use(cookieParser()); 

Then we reqired session module. So first of all install the session module by :

npm install express-session --save

Then to enable the session. we add below code in app.js file.

app.use(session({secret:config.sessionSecret, saveUninitialized : true, resave : true}));

Then come to the routes.js file :-

Let us suppose there is a session variable favColor. Now using session set the color and get in the other page. the code is look like :-

router.get('/setColor', function(req , res , next){
        req.session.favColor = 'Red';
        res.send('Setting favourite color ...!');
    });
    
    router.get('/getColor', function(req , res , next){
        res.send('Favourite Color : ' + (req.session.favColor == undefined?"NOT FOUND":req.session.favColor));
    });
