Design architectural patterns are the core of mobile application development. The architecture of the application provides you with reusable code and minimizes the code duplication that prevents high coupling and provides solutions for the recurring problems. Over the years Mobility Architecture has evolved to keep pace with the current feature needed by mobile applications and to cater to hyperautomation. This article takes us through this journey & also talks about architecture fitment for each of their use cases.
VIPER is a design architectural pattern for mobility development which is an alternative for MVC, MVVM and more. It provides a layer of abstraction that results in a more scalable, reusable and testable code.
Do you want to know when MVC(Module View Controller), MVVM (Model View-Viewmodel) and VIPER(View-Interaction-Presenter-Entity-Routing) design architecture, can be best used? We have created a quick analysis for you, let’s see for ourselves.
The MVC architecture design pattern is used in the presentation layer. This type of architecture is suitable for small or single screen applications like Currency Converter or Login Application.
The MVVM architecture design pattern overcomes all drawbacks of MVC architecture. MVVM separate data layer and business logic layer using Model and View.
VIPER is an acronym for View-Interactor-Presenter-Entity-Router. Each module has their own responsibility in the architecture.
The VIPER architecture design pattern overcomes all drawbacks of MVC and MVVM architecture. This pattern separates the presentation layer, data layer and routing for the system.
Let’s see the difference between MVC(Model–view–controller) , MVVM (Model–view–viewmodel) and VIPER (View-Interactor-Presenter-Entity-Router) :
|
MVC |
MVVM |
VIPER |
|
Better for small or single screen applications like : Calculator, Currency converters. |
Better for medium and large scale applications. |
Better for large scale applications because it maintains routes and lots of files which are not suitable for small or single screen applications. |
|

|
|
UI testing requires efforts as a single controller handles multiple views and models |
Required less effort for unit testing if business logic is loosely coupled with different modules |
Low coupling between different modules which provide good environment for unit testing |
|
Setup is very easy but hard to manage |
Setup is fairly difficult but maintenance of code becomes easy |
Setup requires time and and can involve a learning curve.However scaling and maintaining is the easiest later on |
