Pillars of AngularJS:
It is true that AngularJS is the cement that holds up all the bricks for constructing an authentic website. Directives, Controllers, Scopes, Services and Dependency Injection are the five main pillars of the AngularJS powered website.
Let us explore the 5 pillars of AngularJS in detail that firmly holds the success of an AngularJS powered website.
Directives, one of the most powerful features of AngularJS framework. A developer should have an in-depth knowledge of the Directives as it is the engine that enables a safe and excellent drive. From the framework directives, you could use ng-model or ng-repeat to your own custom directives that grants you the permission to widen the vocabulary of the browser. The HTML elements, attributes and classes are all made to be reused with this distinct feature of the AngularJS.
A link between the view and the controller can be defined as Scope in terms of AngularJS. It can be defined as the application model that can be used to have a watch on expressions and propagate events. It contains the model data.
The AngularJS services enable the sharing of codes across all possible controllers in the code. They are all wired together using the Dependency Injection that is made suitable for the application. AngularJS has a wide range of services which can be used for increased functionality of the application. With an AngularJS module, an application developer can define services by registering the name and factory functions of the service.
5. Dependency Injection:
DI – known as Dependency Injection is spread throughout AngularJS to make developing an easy and fun filled process. It’s functions and designs are similar to a software, where the components are given their dependencies. This makes the client-side dependency management process quite easy and exciting. It not only helps in creating components but also provides them to other components and also resolves their dependencies.
