In this tutorial, we will see how the controller works in the angular library.<\/p>\n<h2>1. Introduction<\/h2>\n<p><em>AngularJS<\/em> is a JavaScript MVC or Model-View-Controller framework developed by Google that lets developers build well structured, easily testable, and maintainable front-end applications. But before we start creating a real application using the angular library, let us see what the important parts of an angular application are.<\/p>\n<p>[ulp id=&#8217;LXJcMJZXSsqGXYW8&#8242;]<\/p>\n<h4>1.1.1 Templates<\/h4>\n<p>In AngularJS, a <span style=\"text-decoration: underline;\">template<\/span> is an <code>HTML<\/code> with added markups. AngularJS library compiles the templates and renders the resultant <code>HTML<\/code> page.<\/p>\n<h4>1.1.2 Directives<\/h4>\n<p><span style=\"text-decoration: underline;\">Directives<\/span> are the markers (i.e. attributes) on a DOM element that tell angular to attach a specific behavior to that DOM element or even transform the DOM element and its children. Most of the directives in the angular library start with the <code>ng<\/code>. The directives consist of the following parts:<\/p>\n<ul>\n<li><code>ng-app<\/code>: The <code>ng-app<\/code> directive is a <em>starting point<\/em>. If the AngularJS framework finds the <code>ng-app<\/code> directive anywhere in the <code>HTML<\/code> document, it bootstraps (i.e. initializes) itself and compiles the <code>HTML<\/code> template<\/li>\n<li><code>ng-model<\/code>: The <code>ng-model<\/code> directive binds an <code>HTML<\/code> element to a property on the <code>$scope<\/code> object. It also binds the values of AngularJS application data to the <code>HTML<\/code> input controls<\/li>\n<li><code>ng-bind<\/code>: The <code>ng-bind<\/code> directive binds the AngularJS application data to the <code>HTML<\/code> tags<\/li>\n<li><code>ng-controller<\/code>: The <code>ng-controller<\/code> directive specifies a controller in the <code>HTML<\/code> element. This controller will add behavior or support the data in that <code>HTML<\/code> element and its child elements<\/li>\n<li><code>ng-repeat<\/code>: The <code>ng-repeat<\/code> directive repeat a set of <code>HTML<\/code> elements for each item in a given collection<\/li>\n<\/ul>\n<h4>1.1.3 Expressions<\/h4>\n<p>An <span style=\"text-decoration: underline;\">expression<\/span> is like a JavaScript code usually wrapped inside the double curly braces such as <code>{{ expression }}<\/code>. AngularJS library evaluates the expression and produces a result.<\/p>\n<h3>1.2 What are Controllers in Angular?<\/h3>\n<p><span style=\"text-decoration: underline;\">Controllers<\/span> in the angular library are used to support the data and the behavior of an angular web application. In <code>HTML<\/code>, the angular controller is defined using the <code>ng-controller<\/code> directive. This tag adds the other functionalities to the scope of the view and here is what the syntax will look like.<\/p>\n<p><span style=\"text-decoration: underline;\"><em>Angular Controller Syntax<\/em><\/span><\/p>\n<pre class=\"brush:js; wrap-lines:false;\">var mainApp = angular.module('myApp', []);\r\n\r\nmainApp.controller('myCtrl', function($scope) {\r\n    $scope.msg = \" Hello World!\";\r\n});\r\n<\/pre>\n<p>The <em>controller<\/em> in angular applications basically acts as a bridge between the <em>model<\/em> and the <em>view<\/em> components and do the following important responsibilities.<\/p>\n<ul>\n<li style=\"list-style-type: none;\">\n<ul>\n<li>Sharing the static or the dynamic results to the application view<\/li>\n<li>Handling the user input elements such as button clicks, input text validation etc.<\/li>\n<li>Processing the user\u2019s input and managing the presentation logic<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n<figure id=\"attachment_20961\" aria-describedby=\"caption-attachment-20961\" style=\"width: 820px\" class=\"wp-caption aligncenter\"><a href=\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/02\/angular_ctrl_ex_project_archi_guide_1.jpg\"><img decoding=\"async\" class=\"wp-image-20961\" src=\"http:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/02\/angular_ctrl_ex_project_archi_guide_1.jpg\" alt=\"Fig. 1: Logical representation of Angular Controller\" width=\"820\" height=\"746\" srcset=\"https:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/02\/angular_ctrl_ex_project_archi_guide_1.jpg 849w, https:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/02\/angular_ctrl_ex_project_archi_guide_1-300x273.jpg 300w, https:\/\/www.webcodegeeks.com\/wp-content\/uploads\/2018\/02\/angular_ctrl_ex_project_archi_guide_1-768x698.jpg 768w\" sizes=\"(max-width: 820px) 100vw, 820px\" \/><\/a><figcaption id=\"caption-attachment-20961\" class=\"wp-caption-text\">Fig. 1: Logical representation of Angular Controller<\/figcaption><\/figure>\n<p>These new APIs make developer&#8217;s life easier, really!
