Angular Tutorial
Last Updated :
13 Jun, 2024
Angular is a powerful open-source TypeScript framework developed by Google for building dynamic web applications. Front-end developers use frameworks like Angular or React to create efficient and interactive user interfaces. Angular simplifies creating Single Page Applications (SPAs) by extending HTML with new attributes.
This Angular tutorial is created to help you in learning Angular quickly and efficiently. Initially, you will learn the fundamentals of AngularJS, including directives, expressions, filters, modules, and controllers. Then, you will learn about other important aspects of AngularJS, such as events, DOM manipulation, forms, input handling, validation, HTTP requests, and more.
AngularJS is a JavaScript framework that extends HTML attributes with directives and binds data to HTML with expressions through a <script> tag.
Prerequisites for Angular
To get the most out of this tutorial, you should already have a basic understanding of the following.
Basic Example of Angular
Angular is a JavaScript framework written in JavaScript. AngularJS is distributed as a JavaScript file, and can be added to a web page with a script tag:
HTML
<!DOCTYPE html>
<html lang="en-US">
<head>
<meta charset="UTF-8">
<title>AngularJS Example</title>
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.6.9/angular.min.js"></script>
</head>
<body>
<div ng-app="myApp" ng-controller="myController">
<p>Enter your name: <input type="text" ng-model="name"></p>
<h1>Hello, {{name}}!</h1>
</div>
<script>
// Define the AngularJS application module
var app = angular.module('myApp', []);
// Define a controller for the application
app.controller('myController', function($scope) {
// Initialize the name variable
$scope.name = "";
});
</script>
</body>
</html>

Why Learn Angular?
- Community Support: Angular is backed by Google and TypeScript (created by Microsoft), resulting in a large and active community. You’ll find plenty of resources, tutorials, and forums to help you along the way.
- Free and Open Source: Angular is free to use, and developers can leverage its components and methods without any cost.
- TypeScript: Angular is built on TypeScript, a statically typed superset of JavaScript. TypeScript provides better tooling, type safety, and improved code quality.
- Angular CLI: The Angular CLI simplifies tasks like project creation, building, and deployment. It streamlines the development process and enforces best practices.
- Cross-Platform Development: Angular, along with tools like NativeScript, allows you to build mobile applications for various platforms using a single codebase.
Features of Angular
- It uses components and directives. Components are the directives with a template.
- It is written in Microsoft’s TypeScript language, which is a superset of ECMAScript 6 (ES6).
- Angular is supported by all the popular mobile browsers.
- Properties enclosed in “()” and “[]” are used to bind data between the view and the model.
- It provides support for TypeScript and JavaScript.
- Angular uses @Route Config{(…)} for routing configuration.
- It has a better structure compared to AngularJS, easier to create and maintain for large applications but behind AngularJS in the case of small applications.
- It comes with the Angular CLI tool.
Applications of Angular
- Single-Page Applications (SPAs): Angular excels at creating SPAs, where a single webpage dynamically updates content as users interact with it.
- Real-Time Applications: Use Angular for chat applications, weather forecasts, and live tracking systems that require immediate updates.
- Enterprise Applications: Angular is commonly used for developing large-scale enterprise applications. Its modular architecture, dependency injection, and TypeScript support make it suitable for building complex and maintainable applications.
- Content Management Systems (CMS): Angular can be used to build custom content management systems, providing a dynamic and responsive user interface for managing content.
History of Angular
- Angular version 1.0 was released in 2012.
- Miško Hevery, a employee at Google, started to work with AngularJS in 2009.
- The project is now officially supported by Google, and the idea turned out very well.
