Developing Single Page Application (SPA)

In this article we will learn about developing a Single Page Application (SPA) through step by step approach.

We have already heard a lot about AngularJS and SPA (Single Page Application). But when we start thinking to develop an SPA application, we have a lot of confusion ie: how to develop SAP application, what steps should I take to develop SAP etc. So here I am going to explain step by step development of a SPA (Single Page Application).

So for SPA we have ng-route and ng-view directive. Ng-route manage the routing of a web application and ng-view allows us to render different view depending on the router.

Now open Visual Studio

Now we need to add AngularJS reference into our application. So right click on Solution Explorer, then select Manage Nuget Packages...

Figure 8: MyScript

Here's your MyScript.js file with the following code:

  1. var app = angular.module('single-page-app', ['ngRoute']);  
  2. app.config(function ($routeProvider) {  
  3.     $routeProvider  
  4.         .when('/', {  
  5.             templateUrl: 'Home.html'  
  6.         })  
  7.         .when('/Article', {  
  8.             templateUrl: 'Article.html'  
  9.         })  
  10.     .when('/Blog', {  
  11.         templateUrl: 'Blog.html'  
  12.     })  
  13.     .when('/ContactUs', {  
  14.         templateUrl: 'ContactUs.html'  
  15.     })  
  16.     .when('/AboutUs', {  
  17.         templateUrl: 'AboutUs.html'  
  18.     });  
  19. });  
  20. app.controller('cfgController', function ($scope) {  
  21.   
  22.     /*       
  23.     Here you can handle controller for specific route as well. 
  24.     */  
  25. });

Now Add Home.html, Article.html, Blog.html, ContactUs.html & AboutUs.html in your application.

Home.html

  1. <div style="padding-left:130px;padding-right:200px;">  
  2.     <h1> Welcome RS - To the SPA World! - HOME</h1>  
  3.     <p>Develop SPA (Single Page Application Step By Step.)</p>  
  4. </div>
