Step-by-Step Angular JS Tutorial for Beginners
AngularJS is a robust JavaScript framework by Google for building dynamic single-page apps (SPAs). It adds vocabulary to HTML so that you can use HTML as your template language. The major advantage of AngularJS lies in its application of the Model-View-Controller (MVC) pattern and Two-Way Data Binding, which automatically minimizes the boilerplate code needed to integrate data between the Model (JavaScript data) and View (HTML elements).
Installation and Setup
AngularJS has no complicated installation procedures like contemporary frameworks (Angular 2+ or React) since you do not usually use Node.js or a command-line interface to install a version 1 project. You just have to include the JavaScript library file in your HTML.
Step 1: Create Project Structure
Create a new directory for your project and include the following two files:
| File Name | Purpose |
| index.html | The main application view and entry point. |
| app.js | The JavaScript file for your AngularJS application logic (module, controller). |
Step 2: Include the AngularJS Library
You may include AngularJS with a Content Delivery Network (CDN), which is the easiest way for beginners.
Add the following code in your index.html file:
<!DOCTYPE html>
<html lang=”en”>
<head>
<meta charset=”UTF-8″>
<title>AngularJS Beginner Tutorial</title>
</head>
<body>
<script src=”https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js”></script>
<script src=”app.js”></script>
</body>
</html>
Core Concepts: Directives, Modules, and Controllers
AngularJS operates by introducing special attributes, referred to as directives, to HTML elements.
Step 3: Define the Application (ng-app)
The ng-app directive is fundamental; it establishes the root element of an AngularJS application and instructs AngularJS to assume control of that part of the HTML.
Adjust your file to incorporate the directive, referencing it to a name you will utilize within your JavaScript file:
<body ng-app=”myApp”>
<script src=”https://ajax.googleapis.com/ajax/libs/angularjs/1.8.2/angular.min.js”></script>
<script src=”app.js”></script>
</body>
Step 4: Build the Module (The Application Container)
The Module is where your application components (controllers, services, filters) get registered.
Define the module named myApp in your app.js file: (matching to the ng-app value)
// app.js
// 1. Create the AngularJS module named ‘myApp’
// The empty array [] is for listing module dependencies (we have none for now)
var app = angular.module(‘myApp’, []);
Step 5: Build the Controller (Application Logic)
The Controller is a JavaScript function that contains the application logic and data. It manages the data flow to the view (HTML).
Define a controller named MyController in your app.js file:
// app.js
var app = angular.module(‘myApp’, []);
// 2. Register a Controller to the module
// $scope is a core object passed to the controller
// It is the data model that binds the controller to the view
app.controller(‘MyController’, function($scope) {
// Define a property on the $scope object
$scope.greeting = “Hello from the AngularJS Controller!”;
$scope.user = {
name: “Alice”,
role: “Frontend Developer”
};
// Define a function on the $scope object
$scope.updateRole = function() {
$scope.user.role = “Senior Developer”;
};
});
Linking Controller and View
Step 6: Connect the Controller with the View (ng-controller)
Use the ng-controller directive on your index.html to associate the HTML section with the MyController that you’ve created.
<body ng-app=”myApp”>
<div ng-controller=”MyController”>
<h2>{{ greeting }}</h2>
</div>
</body>
When you browse index.html, you should see: “Hello from the AngularJS Controller!”
Step 7: Display Data with Expressions
AngularJS utilizes expressions, wrapped in double curly braces {{ }}, to present data from $scope to the HTML.
Modify the div on your index.html:
<div ng-controller=”MyController”>
<h2>Data Display with Expressions</h2>
<p>Message: **{{ greeting }}**</p>
<p>User Name: **{{ user.name }}**</p>
<p>User Role: **{{ user.role }}**</p>
</div>
Two-Way Data Binding (ng-model)
Two-Way Data Binding is probably AngularJS’s strongest feature. The ng-model directive connects the input element’s value directly to a property on the $scope. Any alteration in the input field will update the $scope property in real time, and any alteration to the $scope property will update the input field and all connected expressions in real time.
Step 8: Implement Two-Way Binding
Add an input element to your index.html and scope it to a new $scope property named nameInput.
In index.html:
<div ng-controller=”MyController”>
<h3>Two-Way Data Binding (ng-model)</h3>
<label for=”name”>Enter a name:</label>
<input type=”text” ng-model=”nameInput” id=”name” placeholder=”Type here…”>
<p>Hello, **{{ nameInput }}**!</p>
</div>
Event Handling and Conditional Logic
Step 9: Handle Events (ng-click)
<div ng-controller=”MyController”>
<h3>Event Handling (ng-click)</h3>
<p>Current Role: **{{ user.role }}**</p>
<button ng-click=”updateRole()”>Promote User</button>
</div>
Clicking the “Promote User” button will call the function in MyController, updating the displayed role to “Senior Developer.”
Step 10: Conditional Display (ng-show / ng-if)
You can conditionally show or hide HTML elements with directives such as ng-show and ng-if.
- ng-show/ng-hide: Toggles the CSS display: none; attribute. The element is still in the DOM.
- ng-if: Fully removes or adds the element to/from the DOM (better for advanced structures).
Add a button and toggle a message with a boolean property on the $scope.
In app.js, set the property to initialize it:
app.controller(‘MyController’, function($scope) {
// … other properties …
$scope.showSecret = false;
$scope.toggleSecret = function() {
$scope.showSecret = !$scope.showSecret; // Inverts the value
};
});
In index.html:
<div ng-controller=”MyController”>
<h3>Conditional Logic (ng-show)</h3>
<button ng-click=”toggleSecret()”>
{{ showSecret ? ‘Hide’ : ‘Show’ }} Secret Message
</button>
<p ng-show=”showSecret”>**Shh! This is the secret AngularJS message!**</p>
</div>
Looping with ng-repeat
The ng-repeat directive is employed for iterating over collections (arrays) and providing respective HTML elements for each item. This is important for showing lists of data.
Step 11: Establish Data for Repetition
Add an array of objects to your $scope in app.js:
app.controller(‘MyController’, function($scope) {
// … existing code …
$scope.tasks = [
{ name: “Setup AngularJS”, completed: true },
{ name: “Create Controller”, completed: true },
{ name: “Implement ng-model”, completed: false },
{ name: “Complete Tutorial”, completed: false }
];
});
Step 12: Loop and Show Data
Employ an unordered list and use ng-repeat on the list item in your index.html.
<div ng-controller=”MyController”>
<h3>Looping (ng-repeat)</h3>
<h4>To-Do List:</h4>
<ul>
<li ng-repeat=”task in tasks”>
**{{ $index + 1 }}.** {{ task.name }}
<span ng-if=”task.completed” style=”color: green;”>(Done)</span>
<span ng-if=”!task.completed” style=”color: red;”>(Pending)</span>
</li>
</ul>
</div>
The $index variable is a special attribute offered by ng-repeat that returns the current item’s index in the array.
Filtering and Sorting
AngularJS filters shape data for presentation and can be applied directly in expressions with the pipe symbol (|).
Step 13: Search Filtering
You can filter the list of tasks by including a search box bound by ng-model.
In index.html, include an input field and update the ng-repeat expression:
<div ng-controller=”MyController”>
<h3>Filtering Data</h3>
<label for=”search”>Search Tasks:</label>
<input type=”text” ng-model=”search.name” id=”search” placeholder=”Filter by name…”>
<ul>
<li ng-repeat=”task in tasks | filter: search”>
{{ task.name }}
<span ng-if=”task.completed” style=”color: green;”>(Done)</span>
</li>
</ul>
<p>Showing **{{ (tasks | filter: search).length }}** of **{{ tasks.length }}** tasks.</p>
</div>
Now, when you enter a word in the search box, the list will automatically narrow down to display only those tasks whose name includes the entered word.
Step 14: Sorting Data
The orderBy filter enables you to sort the members of a collection according to a given property.
Update the ng-repeat yet again to sort the filtered list by name:
<div ng-controller=”MyController”>
<h3>Sorting Data</h3>
<p>Current Sort: **Name** | **Reversed: {{ reverseSort ? ‘Yes’ : ‘No’ }}**</p>
<button ng-click=”reverseSort = !reverseSort”>Toggle Sort Direction</button>
<ul>
<li ng-repeat=”task in tasks | filter: search | orderBy: ‘name’: reverseSort”>
</li>
</ul>
</div>
<script>
// In app.js (or inline for simplicity)
// Add this property to your MyController’s $scope:
$scope.reverseSort = false;
</script>
Summary of Core Angular JS Directives and Concepts
| Concept | Directive/Syntax | Purpose |
| Application Root | ng-app=”myModule” | Bootstraps and initializes the AngularJS application. |

Real Time Examples for Angular JS Tutorial for Learners
Here are some real-time examples for AngularJS tutorial for beginners:
Real-Time Form Display and Validation (Two-Way Data Binding)
- Objective: Display user input and validation messages in real-time while they are typing.
- Core Concepts: ng-model, {{ expression }}, and ng-show.
- Mechanism: An <input> field uses ng-model to bind to a $scope variable (e.g., user.email). An {{ expression }} elsewhere on the page displays the email instantly (real-time display). A <p> element with ng-show checks a validation flag (e.g., myForm.email.$invalid) and shows an error message instantly when the input is invalid. This demonstrates how the View and Model stay synchronized.
Dynamic Search Filtering (List Management)
- Objective: Filter a list of items instantly based on what the user inputs in a search field.
- Core Concepts: ng-repeat and the filter filter.
- Mechanism: A list of items (e.g., products, contacts) is rendered using ng-repeat=”item in items | filter: searchText”. An <input> field is bound to the searchText model using ng-model. As the user types, the searchText model updates, and the filter automatically processes the entire list, redrawing the view in real-time without requiring any manual DOM manipulation or JavaScript looping logic.
Live Button State and Text Toggle (Event and Conditional Logic)
- Objective: Update a button’s text and appearance right after an action, presenting the new status.
- Core Concepts: ng-click, ng-bind (or {{ }}), and ng-disabled.
- Mechanism: A button uses ng-click=”toggleStatus()” to flip a boolean on the $scope (e.g., isSubscribed). The button’s text is dynamically set using ng-bind or {{ isSubscribed ? ‘Unsubscribe’ : ‘Subscribe’ }}. Additionally, the button is disabled after clicking using ng-disabled=”isSubmitting”, and a separate message is shown using ng-show=”isSubmitting”. This provides immediate feedback to the user on application state changes.
