Creating a controllers folder

1. Create a folder called controllers inside the root project folder.
2. Create an index.js inside the controllers folder and place the following code:

         // Index controller 
         exports.show = function(req, res) { 
         // Show index content 
             res.render('index', { 
                 title: 'Express' 
             }); 
         }; 
   

3. Edit the app.js file and replace the original index route app.use('/', routes); with the following code:

         app.get('/', index.show); 
   

4. Add the controller path to the app.js file right after var swig = require('swig'); declaration, replace the original code with the following code:

         // Inject index controller 
         var index = require('./controllers/index'); 
   

5. Now it's time to check if all goes as expected: we'll run the application and check the result. Type in your terminal/shell the following command:

    npm start
   

Check the following URL: http://localhost:3000, and you'll see the welcome message of express framework.

Removing the default routes folder

Let's remove the default routes folder:

1. Remove the routes folder and its contents.
2. Remove the user route from the app.js, after the index controller line.
