AngularJS Introduction

  • AngularJS is an open-source front-end application framework.
  • It is mainly maintained by Google and by a community of individuals and corporations.
  • It is maintained by these individuals and corporations to address many of the challenges encountered in developing single-page applications. It is a structural framework for dynamic web apps.

Features of AngularJS

  • AngularJS is most powerful JavaScript-based development framework to create RICH Internet Application.
  • It provides developers options to write a client-side application (using JavaScript) in a clean MVC(Model View Controller) way.
  • The application written in AngularJS is cross-browser compliant. It automatically handles JavaScript code suitable for each browser.
  • It is an open source, completely free, and used by thousands of developers around the world. It is licensed under the Apache License version 2.0.
  • Overall, It is a framework to build a large-scale and high-performance web application.

 Core Features of AngularJS

Following are most important core features of AngularJS

  • AngularJS Data binding − It is an automatic synchronization of data between the model and view components. In Angular, the two-way data binding is done by utilizing the ng-model directive.
  • Scope − These are nothing but the objects that refer to the model.
  • Controller − A controller is defined using the directive called ng-controller. Its application mainly relies on controllers to control the flow of data in the application. A controller is a JavaScript object containing attributes/properties and functions. Each controller accepts $scope as a parameter which refers to the application/module.
  • Services − Services is nothing but the javascript functions. They are responsible to do specific tasks only. This makes them an individual entity which is maintainable and testable.
  • Filters − These select a subset of items from an array and return a new array. An Angular Filter modifies the data before presenting it to the user. We can use these filters with expressions and directives. A filter is usually a predefined keyword, used with the symbol “|” (a pipe).
  • Directives − Directives are markers on DOM elements. These can be used to create custom HTML tags that serve as new, custom widgets. ngBind, ngModel etc. are some of the built-in directives of AnguarJS.
  • Templates − Template is made up of the following elements and attributes.
    • Directive – the ng-app and ng-model are directives.
    • Markup – Markup is nothing but binding the view with a model using the curly braces {}.
    • Filters – Formatting the value in expression filters is done by filters.
    • Form Controls – To validate the user inputs we can use the Angular Forms.

 AngularJS Concepts

Some of the important concepts of AngularJS are as follows:

The AngularJS Components

The AngularJS framework is divided into following five major parts −

  • ng-app − This is the type of directive that defines and links the AngularJS application to HTML.
  • ng-model − This type of directive binds the values of AngularJS application data to HTML input controls.
  • ng-bind − This is another directive that binds the AngularJS Application data to HTML tags.
  • ng-init − This is the directive that initializes application data.
  • ng-repeat − This directive repeats the HTML elements for each item in a collection.

Design goals of AngularJS

  • Decouple DOM manipulation from application logic. This improves the testability of the code.
  • Application testing holds equal importance as to application writing. The testing difficulty is dramatically affected by the way the code is structured.
  • Decouple the client side of an application from the server side. This allows development work to progress in parallel and allows reuse of both sides.
  • Guide developers through the entire journey of building an application from designing the UI to writing the business logic and testing.

Advantages of AngularJS

  • AngularJS will provide the capability to create the Single Page Application in a very clean and maintainable way.
  • It gives the user a rich and responsive experience by providing data binding capability to HTML.
  • Its code is unit testable.
  • It mainly uses dependency injection and makes use of separation of concerns.
  • It also provides reusable components.
  • The developer can write the less code and get more functionality with the use of Angular JS.
