Advanced Express Web Application Development

By: Andrew Keig

Overview of this book

Building an Express application that is reliable, robust, maintainable, testable, and can scale beyond a single server requires a bit of extra thought and effort. Express applications that need to survive in a production environment will need to reach out to the Node ecosystem and beyond, for support.You will start by laying the foundations of your software development journey, as you drive-out features under test. You will move on quickly to expand on your existing knowledge, learning how to create a web API and a consuming client. You will then introduce a real-time element in your application.Following on from this, you will begin a process of incrementally improving your application as you tackle security, introduce SSL support, and how to handle security vulnerabilities. Next, the book will take you through the process of scaling and then decoupling your application. Finally, you will take a look at various ways you can improve your application's performance and reliability.

Feature: Master Page


As a vision user
I want the vision application served as a single page
So that I can spend less time waiting for page loads

Let's add a test to ./test/home.js for our feature Master Page. This resource will GET our master page from route ./ and return a 200 OK response. The Content-Type of the response should be HTML:

   var app = require('../app')
 , request = require('supertest');

describe('vision master page', function(){
  describe('when requesting resource /', function(){
    it('should respond with view', function(done){
      request(app)
        .get('/')
        .expect('Content-Type', /html/)
        .expect(200, done)
    });
  });
});

Let's implement our Master Page feature. Let's create a new module that exposes a route ./lib/routes/home.js and add a new index function. We start by defining a route called index. We create a view model with meta information for a page and then render the view passing the view model:

exports.index = function(req, res){
  var...
