Why AngularJS Became A Popular Framework For App Developers?

For any developer, the choice of building an application finally boils down to the type of framework, programming language, and platform to be used based on the specific business requirements. It is seen that developers often take a liking for specific frameworks, languages and platforms. And when it comes to choosing a specific framework, the factors guiding that are many such as simple HTML codes, open source, and the flexibility of use with frontend development among others. In recent times, AngularJS/Angular 2.0+ has become one of the preferred open source frontend web and hybrid mobile application frameworks for professional app developers. This is evident from the number of popular websites using the framework such as The Guardian, PayPal, Upwork, Netflix, YouTube, freelancer, NBC, Intel, ABC News, Lego, The Weather Channel etc. (Source: peerbits.com).

Single Page Applications (SPAs) These are web applications that run on browsers and have a dynamic interaction with the users. Here, the fixed or static sections of a page written in CSS, HTML or JS are left unchanged while the dynamic sections are refreshed. In other words, instead of fetching a webpage from the server each time a request is made, SPAs fetch only the dynamic ones

leaving the static ones intact. This speeds up the loading of a page thereby offering a rich user experience.

AngularJS ­ Overview It is a JavaScript based open source frontend web application framework from Google, which is used to build Single Page Applications (SPAs). It is also used to build hybrid mobile applications through Ionic, OnSen UI and other frameworks that are based on AngularJS/Angular 2.0+. The framework can be used to build robust, feature rich, and secure video streaming apps, social apps, eCommerce and mCommerce apps, travel apps etc by top web and mobile app development compan ies .

Although the digital landscape has many web and mobile application building technologies, it is the Angular JS/Angular 2.0+ framework that has caught the fancy of web and mobile app developers due to a variety of reasons. Let us discuss the same in some detail.

Why AngularJS/Angular 2.0+?

In today’s digital era where customer experience drives the success or failure of any application, building a web application that is unresponsive, cluttered and sloppy can be suicidal. The need of the day is to give customers a pleasant interactive browsing experience across device platforms. This is where AngularJS/Angular 2.0+ steps in with its advantages. Let us find out about them in some detail.

Easy to use: Developing an application needs lesser coding thanks to the presence of some key features. The framework does not require the use of setters and getters to apply various data models. Moreover, it is easy to manage application development in parallel as the codes do not have any built­in directives. Lesser writing of codes means faster development and execution of applications.

Bidirectional data binding: The functionality helps to update the DOM (Document Object Model) view every time the model changes and vice versa. The HTML generated post the compilation process is rendered by the web browser to reflect on the DOM. The same is repeated for successive page views. In AngularJS/Angular 2.0+ framework, the controller and model states are stored inside the client’s web browser. This mechanism allows pages to be created even without interacting with the server.

Model View Controller (MVC): The dynamic MVC architecture divides the user interface into three parts. The first part is the model that contains the data, the second is the view where the data is reflected, and the third is the controller that interfaces between the view and the model. To facilitate communication among the three elements mentioned above, AngularJS/Angular 2.0+ uses scopes or namespaces applied as JS objects. This segregation of the user interface makes it easier for any AngularJS web application developer to build a client side web application. This is done by putting the MVC elements separately and setting them together when the need arises.

Modularity: One of the best features of AngularJS/Angular 2.0+ is that it allows the creation of multiple modules simultaneously for a single application . This helps in engaging multiple developers in one single project to complete it faster. It also allows reuse of modules in other projects.

Easy Testing: Thanks to the module separation feature wherein developers can build the modules separately and automated testing has become easy. Thus, the modules and services to be tested are processed while the rest are left untouched. Also, the framework does not require any supplementary plugins for testing. So, if you are comfortable with running Karma or Jasmine you can easily learn to use Angular’s unit testing API to conduct quality testing.

Community Support: Coming from Google, AngularJS/Angular 2.0+ has a well knit community of expert developers that works on improving the framework by incorporating the latest developments in technology.

Conclusion AngularJS is a robust JavaScript framework that can create Rich Internet Applications (RIA). It enables the developers to write client side applications using JavaScript in a clean Model View Controller (MVC) style. Applications developed in AngularJS are cross­browser compliant. Being an open source, it is completely free, and used by thousands of developers around the world. Thus, if it is about developing applications by using a JavaScript framework then engaging AngularJS development services will be the best bet.
