What Is a Modular Mobile App Architecture?
Modular mobile app architecture is where functions are built separately, meaning they do not depend on each other to maintain the main codebase. For example, network services could be created separately from actual functionality, despite the app’s features requiring an internet connection to execute properly. In module development, they would be built separately but connected when the app is compiled and run.
Modular architecture differs from monolithic apps, which run on a single codebase, as all functions are built into the same codebase, making them inseparable and dependent on each other to run. Monolithic architectures are typically different from updating and editing because changing one function means other functions will also require updating.
Advantages of Modular Mobile App Architecture
Let’s now explore why you should choose mobile app development over other models, such as monolithic architecture.
Separation of Concerns
Modular architecture allows for the separation of different app functionalities into self-contained modules, with each module focusing on a specific feature or component of the app. This separation enables developers to work independently on different modules, making the codebase more maintainable and easier to understand.
Code Reusability
Modular architecture promotes code reusability. This is because modules can be designed and implemented in a way that allows them to be used across multiple projects or within different parts of the same app. As a result, developers can leverage existing modules rather than building everything from scratch, saving both time and effort.
Scalability and Extensibility
With modular architecture, adding new features or expanding the app becomes more straightforward. Modules can be added or modified independently without affecting other parts of the app. This scalability and extensibility allow for quicker development cycles and easier adaptation to changing requirements.
Improved Collaboration
Modular architecture facilitates collaboration among developers and teams. Since modules are self-contained and have well-defined interfaces, different teams can work on separate modules concurrently without stepping on each other’s toes. This parallel development speeds up the overall development process and enhances teamwork.
Testing and Debugging
Modularity also makes it easier to test and debug mobile applications. By isolating modules, developers can focus on testing individual components or features, ensuring that each module functions correctly. This modular testing approach improves test coverage and helps identify and fix issues more efficiently.
Maintenance and Updates
Another benefit of modular architecture is that it simplifies the maintenance and updating process of mobile apps. Since modules are decoupled, modifying or fixing a specific module doesn’t impact the rest of the app. This reduces the risk of inadvertently introducing bugs during maintenance or updates, and makes it easier to release updates to the app without affecting the entire codebase.
Popular Modular App Architecture Models
Now that you understand why modular architecture is advantageous to mobile app developers, let’s take a look at popular models of modular architecture. These models help to define how modular app development is structured and organized.
Model-View-Presenter (MVP)
MVP separates an application into three components: model (data and business logic), view (user interface), and Presenter (mediator between Model and View). The View notifies the Presenter of user actions, the Presenter updates the Model and then informs the View to update its display. This pattern enables the separation of concerns, allowing independent development and testing of each component.
Model-View-ViewModel (MVVM)
MVVM divides an application into Model (data and business logic), View (user interface), and View Model (mediator between View and Model). The View binds to properties and commands exposed by the View Model, and the View Model updates the View as data changes. This pattern promotes loose coupling and allows for easy testing and separation of concerns between the user interface and business logic.
Clean Architecture
Clean architecture follows a layered approach, consisting of entities (core business objects), use cases (business rules and data flow), interface adapters (data conversion and presentation), and frameworks/drivers (external systems or frameworks). The inner layers do not depend on the outer layers, promoting independence and maintainability. This pattern allows for flexible modifications and replacements of external components without affecting the core business logic.
Popular Implementation Strategies
So, how exactly do mobile app developers implement modular architecture during development? Here are just a few ways.
Module-Based Design
Module-based design involves breaking down a system into discrete modules, each responsible for a specific functionality or feature. These modules interact with each other through well-defined interfaces, encapsulating their implementation details. This approach promotes reusability, as modules can be developed and tested independently, facilitating easier maintenance and updates.
Modularized Codebase
Modularized codebase refers to organizing a codebase into separate modules or components, with each module focused on a specific task. This approach improves code organization, readability, and maintainability. With this strategy, modules can be developed, tested, and updated individually, allowing for easier collaboration among developers. The modularized codebase also enables code reuse, as modules can be shared across different projects or parts of the same project.
Dependency Injection
Dependency injection is a design pattern that involves providing dependencies to a module or component from external sources rather than having the module create or manage its dependencies internally. This approach promotes loose coupling and modularity. Dependencies are injected through constructor parameters, setters, or interfaces, allowing for flexibility in substituting dependencies and making the code more testable, maintainable, and decoupled from specific implementations. Dependency injection containers or frameworks automate the process of managing and injecting dependencies.
