Display the home page

In the / route, you want to check if a session already exists. If not, you prompt the user to verify their account details using their mobile number before they are allowed to continue.

After being authenticated, a session object will be created and you can use this to retrieve and display the user's mobile number.

Enter the following code in the / route handler:

app.get('/', (req, res) => {
	if (!req.session.user) {
		res.render('index', {
			brand: VONAGE_BRAND_NAME,
		});
	} else {
		res.render('index', {
			number: req.session.user.number,
			brand: VONAGE_BRAND_NAME,
		});
	}
});

Run the following command:

Visit http://localhost:3000 in your browser and make sure that the page appears correctly:

Also ensure that when you click the "Verify me" button, you are redirected to a page where you can enter your mobile number:

Although you can enter your number here, you still won't receive a verification code. You'll implement that functionality in the next step!
