Routing in AngularJs

On this post we will see the basic of how to create Single Page Application with AngularJs.

First we need to add reference to AngularJs routing library.
<script src="Scripts/angular.min.js"></script>
<script src="Scripts/angular-route.min.js"></script>

Then we add dependency to ngRoute module in our application module.
var myApp = angular.module('myApp', ['ngRoute']);

Next, use $routeProvider service that will be available after we include the new module to configure the routes that we have. The basic syntax is as follow:
$routeProvider.when('desired_path'), {
    templateUrl: 'location_of_the_partial_view_file',
    controller: 'controller_name_for_this_partial_view'
The path can contain route parameter(s) which is specified with colon (:) and could end with a star (*). Also we could have an optional parameter with a question mark (?). For more information, please see $routeProvider documentation.

Below is an example of a routes configuration:
myApp.config(['$routeProvider', function ($routeProvider) {
    .when('/pageOne', {
        templateUrl: 'partials/page-one.html',
        controller: 'PageOneCtrl'
    .when('/pageTwo', {
        templateUrl: 'partials/page-two.html',
        controller: 'PageTwoCtrl'
        redirectTo: '/'
} ]);

Finally we use ng-view directive to apply the configuration in our main view. For example:
<div data-ng-view></div>

Below is an example of the complete main view:
<!DOCTYPE html>
<html xmlns="" data-ng-app="myApp">
    <script src="" type="text/javascript"></script>
    <script src="" type="text/javascript"></script>
    <script src="Scripts/app.js" type="text/javascript"></script>
    <script src="Scripts/Home/page-one-controller.js" type="text/javascript"></script>
    <script src="Scripts/Home/page-two-controller.js" type="text/javascript"></script>
    <a href="#">Home</a> | <a href="#pageOne">Page One</a> | <a href="#pageTwo">Page Two</a>
    <div data-ng-view></div>

If we want to use HTML5 url mode that is supported by recent browsers, on myApp.config(...) method add a dependency to $locationProvider service then add this line inside the method:
