Image of page 1
OVERVIEW AngularJS is an open-source web application framework. It was originally developed in 2009 by Misko Hevery and Adam Abrons. It is now maintained by Google. Its latest version is 1.7.8 AngularJS is a structural framework for dynamic web applications. It lets you use HTML as your template language and lets you extend HTML's syntax to express your application components clearly and succinctly. Its data binding and dependency injection eliminate much of the code you currently have to write. And it all happens within the browser, making it an ideal partner with any server technology. 2

General Features AngularJS is a efficient framework that can create Rich Internet Applications (RIA). AngularJS provides developers an options to write client side applications using JavaScript in a clean Model View Controller (MVC) way. Applications written in AngularJS are 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. Overall, AngularJS is a framework to build large scale, high-performance, and easy to-maintain web applications. 3

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 bound to a particular scope. Services: AngularJS comes with several built-in services such as $http to make a 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 such as ngBind, ngModel, etc. 4

Templates: These are the rendered view with information from the controller and model. These can be a single file (such as index.html) or multiple views in one page using partials. Routing: It is concept of switching views. Model View Whatever: MVW 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-View Model). The Angular JS team refers it humorously as Model View Whatever. Deep Linking: Deep linking allows 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.
