Is AngularJS actually built on the MVC model?

Software Development | Design, Digital, Technology | Nov 15,2021 | By Nikita Dhiman

The world of web development is always changing and evolving. Nothing actually stays the same after a given length of time, whether it's in terms of a framework or how things are done. Two things became popular among developers as a result of this evolution: Angular and the MVC architecture. We'll discuss both Angular and the MVC architecture in this blog, as well as how the former is utilised to implement the latter.

What is the difference between Angular and AngularJS?

Google created the AngularJS framework, which is based on JavaScript. It was originally released in late 2010, but it wasn't until early 2011 that it was given a stable release. It was brashly touted as a solid framework for building dynamic web programmes using the Model-View-Controller architecture, generally known as the MVC architecture. Google is also in charge of keeping the framework up to date and maintaining it. AngularJS was totally deprecated in the second iteration of updates, and the project was renamed Angular.

What is MVC Architecture, and how does it work?

MVC stands for Model-View-Controller, as you probably already know. The main concept is to have three distinct things that are never mixed up. Developers battled with integrating their logic into their view, which had to be designed in a certain way until the MVC framework was introduced. Things would ordinarily get quite disorganised, which is undesirable, particularly when working on large projects involving thousands of lines of code. It makes tasks like debugging and maintenance extremely difficult. The entities are segregated in the MVC design, therefore the business logic that binds everything together is always written independently. As a result, we may classify MVC as a software pattern rather than an architecture. Let's look at the three primary components of MVC now that we have a better understanding of what it is.

MVC Model Components

It is in charge of handling application data. It updates itself in response to requests from the view and instructions from the controller. View - This component is in charge of showing all or a portion of the data to the users. It also defines the data in a certain format as a result of the controller's choice to provide the data in that manner. They are script-based template systems like JSP, ASP, and PHP that are simple to combine with AJAX. The controller is in charge of managing the relationship between models and views. It responds to user input and interacts with the items in the data model. The controller takes in data, verifies it, and then processes it.

MVC Implementation in Angular

As at the time of writing this article, it's late 2019, and AngularJS has been deprecated for quite some time. Although AngularJS adhered to the MVC framework, the same cannot be true of Angular today. One of MVC's flaws is that any changes we make to the view aren't reflected in the model. The MVVM design was used in Angular2 to solve this problem.

MVVM (Model View View Model) Architecture

MVVM is made up of three components: Model,View and View Model Look at the Model In the MMVM design pattern, the controller is really replaced by the View Model. View Model is a JavaScript function that functions similarly to a controller and is responsible for maintaining the relationship between the view and the model. The difference is that if we update something in the view, it also gets updated in the model, and if we change something in the model, it also shows up in the view, which is known as 2-way binding. The VIEW is our HTML, and the view and view model may interact with each other because of this separation of functions. As a result, the view model is notified anytime there is a change in the view. The model is then updated by the view model. This is how Angular's most recent version works. With that, I'd want to bring my blog to a close.
