Introducing AngularJS

AngularJS is a superheroic J

avaScript MVC framework for the Web. We call it super‐

heroic because AngularJS does so much for us that we only have to focus on our core

application and let AngularJS take care of everything else. It allows us to apply standard,

tried-and-tested software engineering practices traditionally used on the server side in

client-side programming to accelerate frontend development. It provides a consistent

scalable structure that makes it a breeze to develop large, complex applications as part

of a team.

And the best part? It’s all done in pure JavaScript and HTML. No need to learn another

new programming or templating language (though you do have to understand the MVC

and MVVM paradigms of developing applications, which we briefly cover in this book).

And how does it fulfill all these crazy and wonderful, seemingly impossible-to-satisfy

promises?

The AngularJS philosophy is driven by a few key tenets that drive everything from how

to structure your application, to how your applications should be hooked together, to

how to test your application and integrate your code with other libraries. But before we

get into each of these, let’s take a look at why we should even care in the first place.

What Is MVC (Model-View-Controller)?

The core concept behind the AngularJS framework is the MVC architectural pattern.

The Model-View-Controller pattern (or MVVM, which stands for Model-View-

ViewModel, which is quite similar) evolved as a way to separate logical units and con‐

cerns when developing large applications. It gives developers a starting point in deciding

how and where to split responsibilities. The MVC architectural pattern divides an ap‐

plication into three distinct, modular parts:

• The model

is the driving force of the application. This is generally the data behind

the application, usually fetched from the server. Any UI with data that the user sees

is derived from the model, or a subset of the model.

• The view is the UI that the user sees and interacts with. It is dynamic, and generated

based on the current model of the application.

• The controller is the business logic and presentation layer, which peforms actions

such as fetching data, and makes decisions such as how to present the model, which

parts of it to display, etc.

Because the controller is responsible for basically deciding which parts of the model to

display in the view, depending on the implementation, it can also be thought of as a

viewmodel, or a presenter.
