Model View Controller or MVC as it is popularly called, is a software design pattern for developing web applications. A Model View Controller pattern is made up of the following three parts −

Model − It is the lowest level of the pattern responsible for maintaining data.
View − It is responsible for displaying all or a portion of the data to the user.
Controller − It is a software Code that controls the interactions between the Model and View.

MVC is popular because it isolates the application logic from the user interface layer and supports separation of concerns. The controller receives all requests for the application and then works with the model to prepare any data needed by the view. The view then uses the data prepared by the controller to generate a final presentable response. The MVC abstraction can be graphically represented as follows.

The Model

The model is responsible for managing application data. It responds to the request from view and to the instructions from controller to update itself.

The View

A presentation of data in a particular format, triggered by the controller’s decision to present the data. They are script-based template systems such as JSP, ASP, PHP and very easy to integrate with AJAX technology.

The Controller

The controller responds to user input and performs interactions on the data model objects. The controller receives input, validates it, and then performs business operations that modify the state of the data model.

AngularJS is a MVC based framework. In the coming chapters, we will see how AngularJS uses MVC methodology.

AngularJS – First Application

Before we start with creating actual HelloWorld application using AngularJS, let us see what are the actual parts of a AngularJS application. An AngularJS application consists of following three important parts −

ng-app − This directive defines and links an AngularJS application to HTML.
ng-model − This directive binds the values of AngularJS application data to HTML input controls.
ng-bind − This directive binds the AngularJS Application data to HTML tags.

Steps to create AngularJS Application

Step 1: Load framework

Being a pure JavaScript framework, It can be added using <Script> tag.

</script>

Step 2: Define AngularJS Application using ng-app directive

…

</div>

Step 3: Define a model name using ng-model directive

<p>Enter your Name: <input type = “text” ng-model = “name”></p>

Step 4: Bind the value of above model defined using ng-bind directive.

<p>Hello <span ng-bind = “name”></span>!</p>

Steps to run AngularJS Application

Use above mentioned three steps in an HTML page.

testAngularJS.htm

<html>

<head>

<title>AngularJS First Application</title>

</head>

<body>

<h1>Sample Application</h1>

<p>Enter your Name: <input type = “text” ng-model = “name”></p>

<p>Hello <span ng-bind = “name”></span>!</p>

</div>

</script>

</body>

</html>

Output

Open textAngularJS.htm in a web browser. Enter your name and see the result.

How AngularJS integrates with HTML

ng-app directive indicates the start of AngularJS application.
ng-model directive then creates a model variable named “name” which can be used with the html page and within the div having ng-app directive.
ng-bind then uses the name model to be displayed in the html span tag whenever user input something in the text box.
Closing</div> tag indicates the end of AngularJS application.
