      Angular Web Development

      Strengthen Your Website Coding with AngularJS Framework

      AngularJS – one of the most dominant JavaScript frameworks – is quickly becoming the preferred- most-choice for professional web development. It is an innovative client-side technology that extends and combines the power of embraces JavaScript, HTML and CSS; while supporting some of its most evident discrepancies.

      AngularJS

      What’s so special about AngularJS?

      AngularJS is a JavaScript MVC framework built by Google to create viable and properly designed web applications. It helps you to use HTML as your template language, extending the HTML’s syntax to state your application’s components neatly. AngularJS is a great choice if:

      • you are writing a concise testable JavaScript code,
      • your app is communicating with the server via XHR/JSONP, or
      • you are creating a CRUD (create/read/update/delete) client side app that can benefit from automatic DOM manipulation and data-binding which can be expressed using Angular’s declarative templates

      Why should you adopt AngularJS?

      AngularJS is a JavaScript library that offers tools for creating effective browser applications. It simplifies the application development by providing a higher level of abstraction to the developer. It strives to minimize the impedance mismatch between an application’s needs and the document centric HTML by creating new HTML constructs.

      AngularJS helps you to overcome the following troubles:

      • Registering callbacks: Registering callbacks often makes your code confusing. With Angular, you can remove the callbacks and common boilerplate code that helps to reduce the extent of JavaScript coding you need to do. Also, this makes it easier for you to analyze the working of your application.
      • Arranging data to and from the UI: CRUD operations are the cornerstone of ‘AJAX applications’ jobs. The flow of data from the server to an internal object, to an HTML form creates a lot of cluttered and confusing code. AngularJS helps to eliminate all this confusion, leaving the code that expresses the overall application flow instead of the implementation details.
      • Manipulating HTML DOM programmatically: Manipulating HTML DOM is the basis of AJAX applications. However, the process is error-prone and cumbersome. By writing applications with Angular, you are no more confined to the low-level DOM manipulation tasks. It is possible to declaratively describe how the UI should change according to your application state changes.
      • Writing a considerable amount of initialization code to get started: Generally, you have to write a lot of code just to get a standard “Hello World” AJAX app working. AngularJS lets you easily bootstrap your application using the services that are auto-injected into your app. This helps you to develop interactive features quickly while exploiting the entire initialization process in automated tests.

      Features of AngularJS

      AngularJS is a framework with some of the finest interactive features for developers as well as for designers. The basics of the AngularJS can be broken down into 6 key components:

      • Two-Way Data-Binding: AngularJS’ two-way data-binding takes care of the management between the model and the DOM – and it all happens within the browser, making it a perfect framework for any server technology. The directive “ngModel” is used to create a bidirectional binding in AngularJS. Thus, you need not write a large amount of cluttered code.
      • Templates: The HTML templates in AngularJS are construed by the browser in the DOM. Then the DOM becomes input to the AngularJS compiler. AngularJS navigates the DOM template for providing instructions (also known as directives). Communally, the directives are accountable for installing the data-binding for your application view.
      • Dependency Injection: AngularJS’s built-in dependency injection subsystem makes it easier to understand, develop and to test an application. It lets you ask for the dependencies, rather than having to search them or creating them yourself. Moreover, you are also able to define your own custom services while making them available for the injection.
      • Directives: AngularJS’s directives let you extend the regular HTML – making it easier for you to “decorate” elements and manipulate the DOM attributes in exciting ways. The “ngRepeat” directive helps to create a new set of elements in the DOM. You can also create custom directives that well adapt your views to your needs.
      • Controllers: The controllers in AngularJS are used to populate the scope with all the essential data for the view. They can communicate with the view through a particular service named “$scope”. The controller uses this service to give functions and objects to the views that can later be operated with the directives and expressions.
      • Testing: AngularJS applications are easier to test– they are designed with testability in mind. It also comes with a unit and end-to-end test runner setup. The end-to-end tests in API documentation make sure that each part of the framework works correctly.
