What is AngularJS?

The most popular JavaScript frameworks are AngularJS and React. AngularJS has grown to become a big player in the realm of development, specifically. No matter if you are an entry-level your an experienced team leader, learning a new programming language like AngularJS can significantly broaden your career choices. This blog will cover your entire journey to build an AngularJS application, starting with organizing the entire process. In addition, it will point out the reason why AngularJS is a paradigm shift in programming development for you.

Many big companies like YouTube, PayPal, and Netflix use AngularJS because it is easy to use and works really well.

Why Use AngularJS for Web Applications?

There are several reasons why developers and companies choose AngularJS for building web applications:

1. Two-Way Data Binding

AngularJS automatically synchronizes data between the model and the view. Any changes in the UI instantly reflect in the model and vice versa. This reduces the amount of boilerplate code developers need to write.

2. Dependency Injection

AngularJS manages dependencies and injects them where necessary. This promotes modularity and testability.

3. Directives and Templates

AngularJS offers reusable components called directives that help in creating custom HTML elements and attributes. These templates make the development process faster and more organized.

4. MVC Architecture

With the separation of concerns through the Model-View-Controller approach, developers can maintain and update code more easily.

5. Single Page Applications

AngularJS enables you to build SPAs that load content dynamically without refreshing the page. This improves performance and offers a better user experience.

Setting Up the Development Environment

Before you start making an AngularJS app, you need some tools:

• Node.js
  This helps you run JavaScript code on your computer, not just in a browser.
  
  
• NPM (Node Package Manager)
  It helps you download and manage useful parts called packages.
  
  
• Angular CLI
  This is a tool you use in the command line. It makes building Angular apps easier and faster.
  
  

How to install Angular CLI?

Open your terminal or command prompt. Then type this and press Enter:

npm install -g @angular/cli

After installation, verify the version:

ng version

Now you can create a new Angular project:

ng new myapplication

This command makes a new folder called myapplication. Open folder in a text editor like Visual Studio Code to start working on your app.

Building Your First AngularJS Application

Let us learn these simple steps to make a single-page app using AngularJS.

Step 1: Create an Angular Module

A module is the main container of different components in AngularJS.

var app = angular.module('myApp', []);

Step 2: Create a Controller

The controller controls the data of your application and defines the behavior of your view.

app.controller('MainController', function($scope) {

  $scope.message = 'Welcome to AngularJS';

});

Step 3: Link AngularJS in Your HTML File

Add the AngularJS library to your HTML file and connect your controller to it.

<!DOCTYPE html>

<html ng-app="myApp">

<head>

  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js"></script>

</head>

<body ng-controller="MainController">

  <h1>{{message}}</h1>

  <script src="app.js"></script>

</body>

</html>

Step 4: Add Routing to Your Application

For the creation, you need the routing and ngRoute module.

var app = angular.module('myApp', ['ngRoute']);

app.config(function($routeProvider) {

  $routeProvider

  .when('/', {

    templateUrl: 'home.html',

    controller: 'MainController'

  })

  .when('/about', {

    templateUrl: 'about.html',

    controller: 'AboutController'

  })

  .otherwise({redirectTo: '/'});

});

Step 5: Define More Controllers

Each page needs its controller.

app.controller('MainController', function($scope) {

  $scope.message = 'This is the Home Page';

});

app.controller('AboutController', function($scope) {

  $scope.message = 'This is the About Page';

});

Step 6: Create HTML Templates

Create home.html:

<h2>Home</h2>

<p>{{message}}</p>

Create about.html:

<h2>About</h2>

<p>{{message}}</p>

Step 7: Add Navigation and View Container

Modify your main HTML file to include links and a placeholder for views.

<a href="#!/">Home</a>

<a href="#!/about">About</a>

<div ng-view></div>

With all the files in position and properly linked, you now have a complete working single-page application with AngularJS.

Numerous successful companies are dependent on AngularJS to create scalable and dynamic web applications. Professionals with experience in AngularJS are highly sought after by various industries. In order to upgrade your skills and reputation, gaining an Angular Certification Course can prove to be of great assistance.
