Building an Express Application Chapter 2

res.render('index', { title: 'Express' });

});

module.exports = router;

This means that when we access the home page, it renders a page called index that resides

inside views/index.pug and passes a parameter for the title to be displayed on the

page. Now, look at the index.pug file in the views folder, which has the following code:

extends layout

block content

h1= title

p Welcome to #{title}

This means it uses the layout from the layout.pug file and displays an h1 title as well as a

paragraph that renders the title that we passed from the route file. Hence, the output is as

follows:

Pretty simple and straightforward, right?
