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

Figure 1: New Project

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

Now again right click on Project’s Solution Explorer, then Add New Item.

Figure 6: Item Name

Now add a JavaScript file in your project, so right click on project’s Solution Explorer and Add New Item.

Figure 7: Add JavaScript

Figure 8: MyScript

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

var app = angular.module('single-page-app', ['ngRoute']);
app.config(function ($routeProvider) {
$routeProvider
.when('/', {
templateUrl: 'Home.html'
})
.when('/Article', {
templateUrl: 'Article.html'
})
.when('/Blog', {
templateUrl: 'Blog.html'
})
.when('/ContactUs', {
templateUrl: 'ContactUs.html'
})
.when('/AboutUs', {
templateUrl: 'AboutUs.html'
});
});
app.controller('cfgController', function ($scope) {
/*
Here you can handle controller for specific route as well.
*/
});

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

Home.html

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

Now open your Index.html and here's the code:

<!doctype html>
<html lang="en">
