Advantages Of AngularJS Framework

AngularJS Framework

We all know that AngularJS Framework is being widely used these days for developing web applications, especially SPA’s.

Let us see a few important key points of this Framework to understand why it became so popular.

Open Source Framework

  • It is an open source framework and continuously supported by Google.

Browsers Compatibility

  • As it is compiled to native Javascript, it is compatible with all browsers. Because all browsers can understand JavaScript.

Model View Controller Design Pattern

  • It uses Model-View-Controller architecture to design an application.
  • The MVC Design Pattern is being widely used these days as it ensures the development of application into three separate layers which can be managed with more ease.

Responsive Single Page Applications and AJAX

  • It is mainly used to develop Single Page Applications (SPA’s).
  • SPA’s – In this type of applications, generally we have only one HTML page and the page content is dynamically updated based on user interaction using AJAX, which means there are no many round trips to the server.

Most of the processing (update a part of the web page) happens at client side using JavaScript.

  • Responsive Web applications are designed to work on any platform be it phone or laptop or tablet.
  • The website will be rendered appropriately based on the platform we are accessing. This is achieved by using custom CSS style sheets. So the web application will look great on any device.

Two-way Binding

  • Binding the data to view has become very easy with Angular as it can be achieved with few lines of code.
  • Two-way Binding is one of the important features of the AngularJS. Once the controls and models are bound appropriately, any change to either view or model, the other will be updated automatically. We can say that Model and Views are always in synch with each other.

Extending HTML with Angular JS Directives

  • Angular Directives helps us to extend the behavior of the existing HTML elements.

DOM Manipulation

  • HTML/ DOM manipulation can be done with ease with few lines of code.

Form Validations

  • It offers client-side form validation by constantly updating the state of both form and input fields.

Dependency Injection

  • It is a process of providing/ injecting the objects that an object needs instead of having it construct itself.
  • In this way, the code can be made loose coupled which helps in maintaining and testing of the code easy.
  • Tight coupling of the code is not a good practice as it is difficult to maintain the code.
  • Dependency Injection can be implemented in AngularJS.

Testing made easy

  • AngularJS can be tested easily a lot of frameworks are available which help us to write unit test cases and the test the application easily.
  • Some of the famous test frameworks available are Karma and Jasmine.
