What is AngularJs | KITS Trainings

What is Angular JS?

The website is the basic need for marketers to reach a mass number of people. With the high availability of content management systems, website development has become a cakewalk in the IT World. But we cannot except the best website unless you develop using best platform. So what does it mean the best website? A website is considered as the best website if it is user-friendly ( Compatible to all devices and loads in an optimal time across various platforms). So here developing a website is an ordinary thing. But developing a user-friendly application is a challenging thing that is essential in today’s world. So how to develop an intuitive web application. Which platform suits best in developing an intuitive application? Then without the second thought most of the developers vote for AngularJS.  So,

But before know about AngularJs, let us have an initial look at

What is a Framework?

A framework is a collection of code libraries where some functions were predefined. By the utilization of this framework, developers can easily develop lightweight applications. Moreover, the developer can concentrate on actual logic rather than struggling with the code dependencies. In simple words, the utilization of these predefined codes makes the website development in a short period.

Hence now, let’s move into the actual concept

What is Angular JS?

Angular JS is an open-source web application framework developed in 2009. This was developed by Misko Hervy and Adam Abrons. This framework was now maintained by Google. This framework architecture depends on the Model View Controller (MVC) framework that is similar to the Java Script Framework.  Moreover, this framework suits best in developing single-page applications. It is a continuously growing and expanding framework in providing better ways of application development. Moreover, this platform is capable of changing from static HTML to Dynamic HTML. Besides, it provides features like dynamic building, dependency injection, and also the code rewriting. Moreover, Angular JS is different from Angular framework. And AngularJS is also capable of extending HTML attributes with directives. Since, we people have got an basic idea regarding AngularJS, let us have a look at its architecture.

AngularJS Architecture:

As mentioned above, Angular framework works on MVC architecture. So let us have a look at its architecture.

MVC Architecture:

An architecture is basically a pattern used to develop an application. This Angular JS Architecture usually consists of three components. They are :

mvc | KITS Trainings

Model:

It is responsible to manage the application data. It responds to the instruction from the view and the instructions from the control to update it self.

View:

It is responsible for displaying the application data. It also specifies the data in a triggered format by the controller to present the data. Since its an script based template such as JSP, ASP, PHP, it is easy to integrate with the AJAX technology.

Controller:

This component is responsible for connecting the model and the view component.It responds to the user inputs and perform data interactions on the data model objects.

This architecture is very poplar, because. it isolates the application logic from the user interface and supports separation of concerns. Besides, whenever we talk about the MVC architecture, we have to split our application into three components and then write the code to connect them. But when comes to angular JS, all we need to is to split the application into MVC and the framework takes care of the rest. Hence this framework is capable of saving the lot of time and allows to finish the job with less code. Whenever the controller receives the input, it validates the input and performs the business operations that modify the data model state.

What are the AngularJS Components?

AngularJS consist of several components. Let us discuss some of them. They are:

a)Data Binding:

Data binding in AngularJs is a two-way process i.e the view layer of MVC architecture is the exact copy of the Model layer. Hence, there is no necessity to write the special code to bind the data to the HTML Controls. Usually in MVC architectures, we need to continuously update the view layer and model layer to remain in sync with each other. In AngularJs we can say that model and view layer synchronized each other. So when ever the data in the model changes, the view layer reflects the change and vice-versa. All this happens in angular is immediately and automatically. It makes sure that model and view is updated all the times.

b)Templates:

One of the major use of this application framework is make use of templates. Usually what happens in AngularJs, is templates were passed by browser into DOM. Here the DOM becomes the input of the Angular JS Compiler. The Angular JS then travels the DOM templates for rendering the instructions called Directives. The other siblings of Angular JS Work differently. These make use of HTML String, where as AngularJS does not manipulate the template strings. With DOM, we have the privilege to extend directive vocabulary (or) even abstract them into reusable components.

c)Dependency Injection:

It is a software design pattern work on Inversion of the Control. Here the term Inversion control refers to the objects that does not create the other objects. Hence , they used to get the objects from an external source. Moreover, the primary object is not capable of dependent object, so an external source creates a dependent object and gives to the source object for further usage. Hence on the basis of dependency injection, we can create all the information database and can get into the model class. In AngularJS, dependencies were injected using “injectable factory method”(or) constructor function.

d) Scope:

It is an built-in object in AngularJs which contains application data and models. Here the $scope is responsible to transfer the data from controller to the view and vice-versa. Besides, we can create properties to the $scope object inside the controller function and assign a value to it.

e)Controller:

A controller is a java script constructor function that contains the attributes/properties and functions in AngularJS that is responsible to increase the Angular JS Scope. And each controller accepts the scope as a parameter that refers to the application that needs to handle.

Hence likewise, there are many other components of AngularJs. You people can acquire practical knowledge of AngularJS components by live experts with practical use cases through AngularJS Online Course.

Final Words:

With this, I hope you people have got an basic overview of Angular and its components. In the upcoming post of this blog, Ill be sharing you the details of working of various Angular JS components in details and application in IT industry. Meanwhile Have a glance at our AngularJS Interview Questions and crack the interview.
