What is Angular JS?

AngularJS is an open source Model-View-Controller framework which is similar to the JavaScript framework.

Features

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

Core Features

  • Data-binding − It is the automatic synchronization of data between model and view components.
  • Scope − These are objects that refer to the model. They act as a glue between controller and view.
  • Controller − These are JavaScript functions that are bound to a particular scope.
  • Services − AngularJS come with several built-in services for example $https: to make an XMLHttpRequests. These are singleton objects which are instantiated only once in app.
  • Filters − These select a subset of items from an array and returns a new array.
  • Directives − Directives are markers on DOM elements (such as elements, attributes, css, and more). These can be used to create custom HTML tags that serve as new, custom widgets. AngularJS has built-in directives (ngBind, ngModel.)
  • Templates − These are the rendered view with information from the controller and model. These can be a single file (like index.html) or multiple views in one page using "partials".
  • Routing − It is concept of switching views.
  • Model View Whatever − MVC is a design pattern for dividing an application into different parts (called Model, View and Controller), each with distinct responsibilities. AngularJS does not implement MVC in the traditional sense, but rather something closer to MVVM (Model-View-ViewModel). The Angular JS team refers it humorously as Model View Whatever.
  • Deep Linking − Deep linking allows you to encode the state of application in the URL so that it can be bookmarked. The application can then be restored from the URL to the same state.
  • Dependency Injection − AngularJS has a built-in dependency injection subsystem that helps the developer by making the application easier to develop, understand, and test.

2. Why AngularJS is used?

  • Time-saving: Projects that previously used to take many months with other frameworks can now be completed faster with AngularJS.
  • The app is easy to learn and get started: Getting up and running with AngularJS is perhaps the simplest thing a developer can imagine.
  • Data Binding in AngularJS is very easy:
  • A declarative expression of UI: AngularJS is fully structured, understanding and manipulating the components is very easy.
  • Affordability:

AngularJS should be used for development

  • Security
  • Declarative User Interface
  • Integration
  • Data Binding
  • Less Coding
  • Easy Testing

Reason for using Angular JS

  • MVC pattern
  • A declarative user interface.
  • Data models are POJO
  • Behavior with directives
  • Flexibility with filters
  • Write less code
  • DOM manipulations where they belong
  • Service providers where they belong
  • Context aware communication
  • Unit testing ready
  • Solid Community
  • Backed By Google
  • Directives Control
  • Save on time
  • The SPA Help
  • Edge with Modules
  • Ease with Parallel Development
  • Linking Power
  • Full UI Support
  • Contextual PubSub System
  • Super User Experience

3. Some use case of angular JS

  • Navigation Menu
  • Inline Editor
  • Order Form
  • Instant Search
  • Switchable Grid

4. Tools or software used for development

  • Testing and debugging are important parts of the development process especially in an environment like Angular.
  • Karma: Karma is a great test runner made for Angular, but can also be used with any other Javascript framework.
  • Jasmine: Jasmine is used for behavior-driven development (BDD), but you can use it for test-driven development (TDD) with a bit customization.
  • MochaJS: When compared to Jasmine, MochaJS is more flexible but Jasmine comes as an all-in-one package.
  • Protractor: Protractor is probably the most powerful automated end to end (e2e) Angular testing tool.
  • Angular Batarang: Batarang is a Chrome extension for debugging Angular applications.
  • ng-inspector: ng-inspector is a browser extension supported on Chrome and Safari
