Mobile Angular UI - APP Development

In this chapter, we will discuss the use of Using AngularJS and Ionic for app development.
Ionic is an open source framework used for developing mobile applications. It provides tools and services for building Mobile UI with native look and feel. Ionic framework needs native wrapper to be able to run on mobile devices.
In this chapter, we will learn just the basics on how we can make use of ionic and mobile angular UI to develop your app.
For details of ionic refer −  https://www.tutorialspoint.com/ionic/index.htm.
To start working with ionic and angularjs, we need to first install cordova. The command is as follows −
npm install -g cordova

Create a folder ionic_mobileui/ and in that let us create our project setup using the below command −
cordova create ionic-mobileui-angularjs

Here ionic-mobileui-angularjs is the name of our app.
Now let us install the packages that we need in our project. The list is given below −
npm install --save-dev angular angular-route mobile-angular-ui @ionic/core

The files are installed and the folder structure is shown below −
All the angular and ionic files are inside node_modules. We are going to make use of www/ folder. Hence move the angular and ionic js and css files inside www/css/ and www/js/ folders.
Let us modify the index.html with mobile angular UI components and also add app.js in js/ folder.

      Some notes: 
         * gap: is required only on iOS (when using UIWebView) and is needed for JS->native communication 
         * https://ssl.gstatic.com is required only on Android and is needed for TalkBack to function properly 
         * Disables use of inline scripts in order to mitigate risk of XSS vulnerabilities. To change this: 
            * Enable inline JS: add 'unsafe-inline' to default-src

All the js and css files are added in the head section. The module and controller is created inside app.js as shown below −
/* eslint no-alert: 0 */

'use strict';
// 
// Here is how to define your module 
// has dependent on mobile-angular-ui 
// var app=angular.module('myFirstApp', [
   'ngRoute', 
   'mobile-angular-ui' 
]); 
app.config(function($routeProvider, $locationProvider) { 
   $routeProvider 
   .when("/", { 
      templateUrl : "home/home.html" 
   }); 
   $locationProvider.html5Mode({enabled:true, requireBase:false}); 
});
app.directive('dragItem', ['$drag', function($drag) { 
   return { 
      controller: function($scope, $element) { 
         $drag.bind($element, 
            { 
               transform: $drag.TRANSLATE_BOTH, 
               end: function(drag) { 
                  drag.reset(); 
               } 
            }, 
            { 
               sensitiveArea: $element.parent() 
            } 
         ); 
      } 
   }; 
}]);
app.controller('MainController', function($rootScope, $scope, $routeParams) { 
   $scope.msg="Welcome to Tutorialspoint!"; 
});
Create home/home.html file in www/ folder. Following are details inside home.html.
<div class="list-group text-center"> 
   <div class="list-group-item list-group-item-home">
      <h1>{{msg}}</h1> 
   </div> 
</div>
To run the app using cordova, execute the following command −
cordova platform add browser

Next, execute the below command to test the app in the browser −
cordova run

Hit the url : http://localhost:8000 in the browser, to test the app.
Open home/home.html, add the following ionic card template −
<ion-card> 
   <ion-card-header> 
      <ion-card-subtitle>Ionic Card</ion-card-subtitle> 
      <ion-card-title>Mobile Angular UI + Ionic</ion-card-title>
   </ion-card-header>

   <ion-card-content> 
      Welcome To TutorialsPoint! 
   </ion-card-content> 
</ion-card>
Once done stop cordova run and run it again. You should see the ionic card details as shown below −
So now you can create an app of your choice by using AngularJs, Mobile Angular UI and Ionic.
