MVW or “Model View Whatever”

AngularJS is designed to bring “simple” back to the development of complex web applications. AngularJS uses a MVW or MV* structure and also works if we retain the Model-View-Controller (MVC) pattern. Presentation logic is related to how objects are displayed to users of the application whereas business logic is the internal logic related to the functionality of an application. The outer look of the webpage can change as per the client demands or the need to revamp the look of the website. Since AngularJS follows the MVW structural pattern, it enables us to separate presentation logic from the business logic, thereby causing minimal disruption in the underlying code infrastructure.

Simplify the creation of your applications

Unlike other frameworks or libraries, AngularJS extends HTML rather than abstracting it away. Because of this, it reduces the server load of applications and allows for easier testing. If used correctly, it should also allow for human-readable code.

The strength of AngularJS’s data binding and dependency injection is another reason you should be getting excited about this framework. AngularJS eliminates the need for wrappers, getters/setters or class declarations, so you can express your data through simple arrays, or through custom types.

Because AngularJS is a MVW framework, you can also retain the MVC or MVVM architecture best suited for your application. This allows for applications to be modified, maintainable and testable with less technical debt, effort, and difficulty. That is not to say that AngularJS isn’t complex and difficult to master of course, because as the size of applications grow, so does the complexity of code organization and testing.

Frameworks always promise easier, efficient, and exciting web application development if you adopt them for your programming purposes. Using AngularJS capitalizes on this promise; it allows you to build complex interactive and dynamic features for rapid development and templating, which can be applied as easily as applying an attribute to HTML.

We don’t mean to be obtuse, but…

AngularJS has made its foray into different territories. It can be used in several, different ways. Let’s look at the features and utilities that form AngularJS:

AngularUI

AngularUI is AngularJS’s companion UI suite, with a relationship similar to that of jQueryUI and jQuery. It is a utility package and complements AngularJS rather well. It has varied features and runs some projects such as UI-Bootstrap, which is essentially an implementation of all Bootstrap components in AngularJS.

Custom directives

AngularJS assists in developing custom HTML elements to simplify DOM manipulation. AngularJS has a lot of built-in directives; however, you can also add your custom made directives to it to enhance your dynamic applications. AngularJS also aids in two-way data binding using built-in and custom directives. Two-way data binding occurs when we update the Model whenever the View changes and vice versa, which eliminates the need to manipulate the DOM.

Communicating with the backend server

AngularJS has a general purpose $httpservice to issue XHR (XMLHttpRequest) and JSONP calls so AngularJS can communicate with the backend. In addition to this, it has a specialized $resource service using which we can talk to the RESTFUL endpoints, thereby retrieving and fetching data.

Creating forms using a dynamic interaction

AngularJS enhances the HTML forms with input directives, valid directives, and controllers. In AngularJS, we decouple the model and

the view. The input directives take care of the process of displaying the values whereas AngularJS updates the Model when the values change. The best part is that we can retain the same MVC pattern we have used in our web application as AngularJS follows the MVW pattern.
