Why is Angular JS becoming so popular with Java Applications ?

Why is Angular JS becoming so popular with Java Applications ?In general, a java application has 3 layers, Presentation Layer, Service Layer & Data Layer. The service layer is the main part for a java developer where you spend most of the time in your development career. But without having a rich presentation an application can’t be completed. Angular JS is known for the most popular framework for the front-end development of  a web application & mobile application as well. We use angular JS in presentation layer to make application more attractive, responsive & user friendly. In this blog we will talk about ‘Why is Angular JS becoming so popular with Java Applications?’

What is an Angular JS ?

Angular JS is an open source front-end application design framework and development platform built on top of JavaScript for creating efficient and sophisticated single-page apps. It is maintained by Google. It addresses many of the challenges encountered in developing single-page applications so sometimes we call it SPA. The design goals of Angular JS includes decoupling DOM manipulation from application logic, decoupling the client side of an application from the server-side. One of the official website for Angular JS is angularjs.org.

Advantages of Using Angular JS ?

1. Open Source :

AngularJS is open source, completely free, and used by millions of developers around the world.

2. Cross Browser Compliant 

Unlike JavaScript & jQuery, Applications written in AngularJS are cross-browser compliant. It handles JavaScript code suitable for a particular browser automatically.

3. Fast & Less Code :

With AngularJS, the developers can achieve more functionality with short code. As a framework it comes with embedded most common functionalities which can reoccur again & again.

4. Rich UI :

AngularJS is an efficient framework with capabilities to create Rich Internet Applications (RIA) with rich user interface.

5. Built-in Services :

AngularJS comes with several built-in services such as $http to make a XMLHttpRequests, $location, $timeout, $interval. These are singleton objects which are instantiated only once in the app. Apart from that we can make custom services easily.

6. Reusable Components :

AngularJS provides reusable components which helps developers to reuse the same block of code written before. Therefore helps in saving time to code and making AngularJS a unique framework for the developers.

7. Convenient Testing :

It has great testing capabilities which provides support to both end-to-end and unit testing. It make testing easy and flexible at any level of development.

8. Light-weight Architecture :

Some large application contains more than 100 components. AngularJS makes it easy to develop them even after a new developer joins the project in the middle of the process. The architecture is developed in such a way that it helps the developer to locate and develop the code easily.

9. Separation of Responsibilities :

AngularJS provides developers an options to write client side applications using JavaScript in a clean Model View Controller (MVC) way without any burden on future integrations. Views are pure html pages, and controllers are in JavaScript do the business processing.

10. Directives :

Directives are markers on DOM elements such as elements, attributes, css, and more. We can use them to create custom HTML tags that serve as new, custom widgets. AngularJS has built-in directives such as ngBind, ngModel, etc.

11. Dependency Injection:

AngularJS has a built-in dependency injection subsystem that helps the developer to create, understand, and test the applications easily. It uses dependency injection and make use of separation of concerns.

Why is Angular JS becoming so popular with Java Applications ?

Applications developed on Java were known for its robustness, more secure, best server side programmed and other middle-ware services but they were lacking in presentation part to some extent. Like .Net or php bases applications, Java applications were not very rich in user interfaces. Java is famous for back-end development whereas Angular JS is for front-end. Introduction of Angular JS & its easy integration with Java frameworks like Spring makes Java application rich in User Interfaces as well. Angular JS & Java are used to develop both web application & Mobile application so combination of these two are very popular. You can find Angular JS easily in any Job description of Java developers opening these days.
