Introduction to AngularJS

 

Google’s AngularJS is an all-inclusive JavaScript model-view-controller (MVC) framework that makes it very easy to quickly build applications that run well on any desktop or mobile platform. In a very short period of time, AngularJS has moved from being an unknown open source offering to one of the best known and most widely used JavaScript client-side frameworks offered. AngularJS 1.3 and greater combined with jQuery and Twitter Bootstrap give you everything you need to rapidly build HTML5

JavaScript application frontends that use REST web services for the backend processes. This book will show you how to use all three frontend components to harness the power of REST services on the backend and quickly build powerful mobile and desktop applications.

 

JavaScript Client-Side Frameworks

 

JavaScript client-side applications run on the user’s device or PC, and therefore shift the workload to the user’s hardware and away from the server. Until fairly recently, serverside web MVC frameworks like Struts, Spring MVC, and ASP.NET were the frameworks of choice for most web-based software development projects. JavaScript client-side frameworks, however, are sustainable models that offer many advantages over conventional web frameworks, such as simplicity, rapid development, speed of operation, testability, and the ability to package the entire application and deploy it to all mobile

devices and the Web with relative ease. You can build your application one time and deploy and run it anywhere, on any platform, with no modifications. That’s powerful AngularJS makes that process even faster and easier. It helps you build frontend applications in days rather than months and has complete support for unit testing to help reduce quality assurance (QA) time. AngularJS has a rich set of user documentation and great community support to help answer questions during your development process. 

Models and views in AngularJS are much simpler than what you find in most JavaScript client-side frameworks. Controllers, often missing in other JavaScript client-side frameworks, are key functional components in AngularJS. 

Figure 1-1 shows a diagram of an AngularJS application and all related MVC components. Once the AngularJS application is launched, the model, view, controller, and all HTML documents are loaded on the user’s mobile or desktop device and run entirely on the user’s hardware. As you can see, calls are made to the backend REST services, where all business logic and business processes are located. The backend REST services can be located on a private web server or in the cloud (which is most often the case). 

Cloud REST services can scale from a handful of users to millions of users with relative ease.
