Introduction To AngularJS
What is Angular JS?
AngularJS is a JavaScript framework. It is known for its client-side framework. It supports MVC features that help develop dynamic applications. AngularJS is an open-source framework that Google introduced. It has a similar syntax as HTML and JavaScript. Through HTML, you can create static web pages, but with the help of AngularJS, you can create dynamic HTML web pages. If you want to learn AngularJS basics, it is better to know HTML and JavaScript as it depends on these web development languages.
Most developers prefer AngularJS as it allows them to create dynamic web pages. It adds various attributes and components to HTML, enhancing its ability to create dynamic HTML web pages. With the help of simple JavaScript, you can now utilize AngularJS to create custom attributes. You can download it for free as it is open-source. You can visit the angularjs.org website to download the latest version for your system. You can also download it through GitHub and go through its source code.
Below is a code snippet of AngularJS simple application:
<!DOCTYPE html>
<html>
<head>
<script src=”https://ajax.googleapis.com/ajax/libs/angularjs/1.3.16/angular.min.js”>
</script>
</head>
<body ng-app>
Name: <input type=”text ng-model=”name” /> <br/>
Welcome <label ng-bind=”name”></label>
</body>
</html>
The above code will provide you with a textbox where you can enter your name. The label specified will be returned with your name.
For example, the output will be:
Name ________
Welcome ________
If you enter “ABC” in the textbox in front of Name, the exact text will appear in front of Welcome. In the given example, the output will be Welcome ABC.
AngularJS is mainly used for developing Single Page Web Applications(SPAs). SPA(Single Page Web Application) is proven to be more interactive with the user and allows developers to create engaging and unique websites or web applications. It dynamically updates the content on the web page with the new data available on the webserver. It outsmarts the traditional method of web browser loading the entire new page. SPA results in faster performance of the website and makes it look like a native app. Now you can use AngularJS to achieve SPAs in a much more impactful manner.
One example of AngularJS being utilized for SPAs is Netflix. The client-side framework of Netflix is developed with the help of AngularJS, which enriches its user experience on web applications. With the use of SPA implemented through AngularJS, Netflix has easy navigation for its users, and also it doesn’t need to refresh the whole page for any new requirement. This client-side feature is enabled with the help of AngularJS which allows bidirectional UI data binding. Hence, it makes the websites and web applications more engaging and user-friendly.
Model View Controller is commonly known as MVC. It is the software architecture that allows the development of efficient web applications. It is considered an efficient architecture because it enables developers to separate the application logic from the users and enables only the user interface layer of the application to be displayed. The Model of MVC architecture is responsible for managing the application data. It follows the instructions given by the controller to update itself and responds to the requests raised by the view.
The View MVC architecture takes the responsibility of displaying a portion of the data or the whole data to the users. The data is presented only when there is a trigger from the controller. The displaying of the data totally depends upon the decision of the controller. The data to be presented are in script-based templates like PHP, JSP, etc. This template system is very easy to be integrated with AJAX technology. Coming to the Controller, you can consider it as the brain of the MVC architecture. It plays a significant role in making this architecture successful. It handles the relation between models and views.
There are many beneficial features of AngularJS that allow developers to create an efficient web application or a website that results in comparatively better performance. The controller can perform interactions on the data model objects and respond to the user inputs. It receives and validates the inputs and conducts business operations to modify the data model’s state. Thus, the MVC platform allows one to develop SEO-friendly web applications or web pages. It also allows you to generate SEO-friendly URLs, increasing visits from a specific application.
Some of the crucial features of Angular JS include:
-
It supports the two-way binding of the application data.
-
It efficiently makes use of MVC architecture for better performance.
-
It supports Single Page applications(SPA) and routing.
-
It allows restful services.
-
It supports dependency injection.
-
It will enable developers to create Rich Internet Applications(RIA) because of its efficient framework.
-
Applications developed using AngularJS are supportive of cross-browser.
-
It automatically handles the JavaScript code that is suitable for the respective browser.
AngularJS is very useful to developers as it helps them achieve more functionality with less code. It also allows them to reuse the code as it provides reusable components. AngularJS is unit testable. HTML can achieve data binding with the help of the AngularJS framework. Hence, it provides users with a responsive and rich experience. The directives of AngularJS include ng-app, ng-model, and ng-bind. The ng-app directive allows you to define and link the AngularJS application to HTML.
The ng-model directive allows you to bind the values of the application data to HTML input controls. The ng-bind directive works to bind the application data to HTML tags. You can now learn Angular JS basics with the help of this free Introduction to AngularJS course for beginners. Complete the course and secure a certificate in AngularJS.
