Introduction to MVVM with Advantages



MVVM (Model-View-ViewModel) refers to clean architecture and supports the separation of projects into various modes. MVVM helps to facilitate the development process and to manage the different components in an easier form. 

Separation of the model brings transparency and turns the handling of the coding process into simpler and into a structured form. Hence, MVVM turns the code into the logical process. Each code functionality and response can be separated and tested individually. 

MVVM is based on the following model: 

MVVM works on the Model ViewModel View architectural structure. 

Model - Helps to reusable code 

The layer model refers to data and business logic. It rechecks the data and logic of the app matches with the other models and can decouple completely with the other models such as ModelView and view. This layer helps to sort out future issues at an early stage. 

ViewModel

The ViewModel layer interacts with the model layer, it is considered as a value converter. This layer is responsible for the conversation of the various data objects. Demands platform-specific code. With this model, the data can be easily managed as well as presented in the best way. 


View - User Interference

The view layer is responsible to display the logic elements. With reference to ViewModel, it helps to get updates and run UI attributes accordingly. 

Advantages of MVVM Framework 

Maintainability 

Different types of code can be separated easier, and particular functionality can be focused. Modification can also be held without affecting the other part or functionalities of the system and coding part. Hence, MVVM helps to keep you remain agile and forward you to the latest releaser faster. 

Extensibility

Developers are enabled to place the right architecture at any stage of the development part. They can replace or can add new codes to bring the development process on the right platform. The maintainability feature turns it more reliable and any part,  or the code can be reused again in the new project or in the same if further required. 

Testability 

With MVVM each piece of code becomes more powerful and individually both the codes extremely and internally are tested. Unit tests of the core code can be written easier, faster, and in a reliable manner. After modification of the code, the coding functionalities can be rechecked individually only that part. Also, developers can check the individual more parts also or the whole process for the satisfaction that the process or the coding functionalities are responding in the right and accurate method. 

In the testing process, developers can also exclude UI extension interaction. Additionally, the presentation and logic layers have blended together. 

Conclusion 

MVVM has separated the process into the major part, so the coding testing process can be individually checked to avoid future hurdles. MVVM framework has turned the development process into more reliable and better, now developers are enabled to check the process and stay assured for the reliable development process.

MVVM vs MVP vs MVC--Which Architectural Pattern You Should Go For

In the world that we live in, we have been surrounded by modern, state-of-the-art programming tools and technologies. Thanks to this widespread diversity, programmers today can build intricate, considerable, and highly functional software. Hitherto, the necessity of structuring big projects eventually started.

Further, to solve the problem of complex yet structured projects, architectural patterns were created. By definition, an architectural pattern is nothing but a general, reusable solution to some of the most commonly occurring problems in software architecture confined within a given context.

Today, there is a large range of architectural patterns that have been segmented into many groups. Out of all the existing ones, three of those are widely popular and accepted globally: MVC, MVP, MVVM. These patterns are generally used in developing web, mobile and desktop applications. MVVM development services and MVC development services are among the most sought after services in the market today.

MVC, MVP and MVVM are layered style patterns, where the ultimate goal is to decouple the project structure into three major components:
  • Business logic of the application
  • User interface (UI) layer
  • Application layer which holds the interaction between the app’s logic and the UI.

What is MVC?
MVC stands for Model-View-Controller. Tagging it as the classic architectural pattern wouldn’t be an injustice. MVC is the most widely used pattern of all. All the components of MVC perform their individual duties up to the T.

MVC, though widely used, is considered to be complex. Developers need to spend enough time to understand the whole idea behind its engineering. Looking at one of the cons, although the concept of MVC describes decoupling, it doesn’t allow developers of the Model ignore the structure of the Views. Also, sometimes it becomes cumbersome to debug MVC architecture considering the event-driven nature of the UI code.

What is MVP?
MVP or Model-View-Presenter, is in general, the scion of MVC design. The ‘Model’ in MVP handles the exact same responsibilities as in MVC. You can think of the ‘Presenter’ as a transformed ‘Controller’.

It is responsible for establishing a communication between the ‘View’ and ‘Model’. It then redirects the user’s input from View to Model and transmits the processed data back to the View. In MVP, the View and the presenter are two completely different entities and communicate to each other by an interface.

What is MVVM?
MVVM is the newest entrant among apex architectural patterns. What MVVM does is that it divides an existing application into three basic components: Model-View-ViewModel. Since this supports two-way data binding between View and ViewModel, it allows for automatic propagation of changes inside the state of ViewModel to the View.

The ‘Model’ performs the same duties as Models in MVC and MVP. The View is the one that receives data through data binding system and in return displays it to the user with the help of UI controls. The ‘ViewModel’ handles the defining methods and functions that assist in maintaining the View’s state, triggering events in the View and manipulating the Model as a response to changing of the View. For this reason, developers find it breeze while working in MVVM framework development.

Conclusion

In order to choose the architecture of the future applications, as a developer you need to set the tasks clearly in your mind and weigh down the given capabilities of these technologies. Out of the mentioned technologies, web developers use MVC pattern while  desktop applications provide MVP and MVVM solutions and mobile developers implement different patterns.
