The Javascript MVC frameworks and libraries came into the spotlight in the year 2012. AngularJS is a leading Javascript MVC framework which has been created by Google and is widely used for web and mobile app development in India. AngularJS can be used to build web applications with proper architecture that are easy to maintain.

What is AngularJS?

It is an MVC framework which defines several concepts so that your web application can be properly organized. It allows you to define your application with a module which can vary in different applications. AngularJS enhances the HTML by attaching directives to your web pages with new tags or attributes or expression so as to define very powerful templates directly into the HTML. AngularJS helps you structure as well as test your javascript code effortlessly, thanks to the use of dependency injection. The utility code can also be easily factorized into services which can be injected in the controllers.

Basic Features of Angular JS

  • It is a powerful JavaScript based development framework which can be used to create RIA (Rich Internet Application).

  • Applications written in Angular JS are cross-browser compliant. The JavaScript code suitable for every browser is automatically handled by AngularJS.

  • Developers can use Angular JS to write client-side applications using JavaScript in a clean MVC way.

  • It is an open source, completely free platform and is widely used by numerous developers across the world.

  • AngularJS is one of the best frameworks which can be used to build large-scale and high-performance web applications while ensuring they are easy to maintain.

Technical Features of AngularJS

The most important core features of AngularJS are as follows:

  • Data Binding: It is the automatic data synchronization between view and model components.

  • Scope: These are the objects which refer to the model. They act as glue between view and the controller.

  • Controller: These are the JavaScript functions bound to a particular scope.

  • Filters: The filters select a subset of items from an array and return a new array.

  • Services: AngularJS comes with numerous in-built services. For example, $http makes an XMLHttpRequest. These are the singleton objects that are instantiated in the app only once.

  • Directives: These are the markers on various DOM elements like attributes, CSS and more. Directives can be used to create custom HTML tags which serve as new and custom widgets. AngularJS comes with built-in directives such as ngBind, ngModel , etc.

  • Routing: It is the concept of switching views.

  • Templates: Templates are the rendered view with useful information from the model and controller. These can either be as a single file like index.html or can have multiple views on a single page using partials.

  • Model View Whatever: MVC is the design pattern of dividing an application into different parts namely Model, View and Controller each having distinct responsibilities. As it is different from traditional MVC model so sometimes referred as Model View Whatever.

  • Dependency Injection: The built-in dependency injection subsystem of AngularJS helps the developer by making applications easier to develop, understand or test.

  • Deep Linking: This feature enables you to encode the state of the application in URL which lets you bookmark it. The application can then be restored to the same state from the URL.

Advantages of Using AngularJS

  • It lets you create Single Page Application in a clean and maintainable manner.

  • The AngularJS code is unit testable.

  • It provides data binding capability to HTML and as a result, user has a rich and responsive experience.

  • It uses dependency injection and also makes use of separation of concerns.

  • AngularJS offers reusable components.

  • The views are as pure HTML pages in AngularJS and controllers written in JavaScript which are responsible for business processing.

  • AngularJS lets you write less code and get more functionality.

  • The AngularJS applications run on all browsers and smartphones (both iOS and android based phones and tablets)

The Components of AngularJS Framework

The AngularJS framework has three major parts which include:

  1. ng-app: It is a directive that defines and links an AngularJS application to HTML.

  2. ng-model: This directive helps bind the values of AngularJS application data to the HTML input controls.

  3. ng-bind: This directive binds the data of AngularJS application to HTML tags.

Thus, it is better to design your website or application using AngularJS framework due to its multiple advantages. You can either design the website yourself or can also contact a provider who offers web development services in Chandigarh. Get your own responsive application and website designed by the experts!
