Why AngularJS is the most preferred tool for web application development?

Web application development is a challenge for any developer. Those challenges during the development process can be overcome by using the right tools and technologies. One such tool that is preferred mostly for web application development is AngularJS, which delivers a sophisticated user experience to customers.

Google Trends has confirmed that AngularJS is the faster-growing framework compared to other traditional frameworks such as Ember.js and Backbone.js.

 AngularJS Directives

AngularJS has an outstanding fan following among web developers as it is an open source web application framework that helps solve challenges in single-page application development. It provides a framework for components that are used in rich internet applications and client-side model-view-controller to simplify both the development and testing of such applications.

Here are some reasons why AngularJS is considered as the most preferred tool for web application development:

Directives add Behavior to HTML Element

AngularJS directives control the interpretation of HTML and help developers to produce new application-specific HTML element, which is completely reusable. They define the behavior of specific presentation components, perform all manipulations in DOM attributes and hide complex DOM structure.

AngularJS directives include:

  • HTML element directives (<angular></angular>)
  • Attribute directives (<div data-angular></div>)
  • CSS class directives (<div class=”angular”></div>)
  • Comment directives (<!–directive:angular–>)

AngularJS directives extend your HTML to generate dynamic web applications. It plays an important role in including Angular’s functionality into a page. A directive placed in HTML attributes (prefixed with “ng”) works as a standalone element and separate them from your MVC app. Some of the most used Angular directives are ng-repeat, ng-app, ng-model, ng-bind, ng-class and ng-controller.

Interpretive User Interface

AngularJS utilizes HTML, which is a declarative language, to determine UI of an application. HTML delivers a structured UI that is more intuitive and can be manipulated easily.  A developer can better understand the outcome of UI by just reading the HTML and JavaScript components. This helps the developer to create flexible and interactive web applications.

AngularJS takes a declarative approach to enable adapting and extending HTML, which makes application development and testing easier.

Manage Dependencies Perfectly

AngularJS includes a pre-built injector subsystem, which is capable for creating elements that deal with their dependencies and address them to other elements as you required. Dependency injection (DI) supports AngularJS to reduce a load on the server side by carrying regular services from server side to web applications on the client-side, which makes web apps much quicker and faster.

AngularJS can manage dependencies efficiently as it allows you to divide web application into logical modules which depends on each other and initialize separately. As DI is extensive throughout Angular, a developer can add a particular dependency as a framework to AngularJS service function.

Code Less

One of the extensive features of AngularJS is that it helps a developer to code less. AngularJS include two-way data binding, which minimizes server refresh cycles and help the web apps to associate with browser directly to reload or to open a new page. It reduces the trouble of writing immense codes by authorizing an automated synchronization of data.

Automatic data synchronization helps developers from manual data placing and DOM manipulations and drives to focus on important aspects of a development process.

Filters Render Flexibility

Filters are autonomous features that involve the transformation of refined data before it reaches the view. It also manages activities such as pagination, reversing a text string, formatting a number with decimal points, filtering an array based on conditions, etc.

AngularJS is equipped with many advance features to create a storable HTML table, you don’t need to write a single line of JavaScript code. They can be used in directives, controllers, and services. Filters clarify the intention of UI and provide flexibility to AngularJS so that developers can get started efficiently.

Lesser Effort for Testing

Automated testing saves your effort and time. AngularJS is built in such a way that it improves testability and performance of front-end codebase. As it includes two-way data binding and dependency injection, the code is easy to reuse, simple to test, effortless to maintain and free from the boilerplate.

AngularJS uses “Protractor” for end-to-end testing. It also helps to test individual units of your code. Developers have built a Google Chrome extension, named as “AngularJS Batarang,” which helps to debug their applications inside the browser.

Though there are number of open-source JavaScript frameworks available on the web, AngularJS has an incredible backing due to its outstanding features. It simplifies development and testing process and supports developers to build a performance-driven, well-architected and minimal maintainable rich web applications.
