What are the best practices for building a scalable and modular architecture for your mobile app?

My expertise in developing mobile applications that are scalable and modular can be summarized into three main areas: Focus on performance and resource efficiency. Mobile devices have limited resources, so optimizing your app to run smoothly and efficiently is essential. Pay attention to security. Implement appropriate measures to protect user data and prevent security vulnerabilities. Design for the future. Consider how your app might evolve and grow in the future. This will help you make informed decisions about your architecture today. It's important to iterate and experiment when building a great architecture and adjust your approach as needed.

For mobile apps, always functionalities, data request and responsive must be light weight, so data will be transferred easily even in low bandwidth network. Each integration must be in event driven. Too many error handles for the request and responsive is not suggestable, and database server connection timeout should be less, upcoming requests need to be stopped if any server is not responding on time. For mobile apps retry logic not required for when deadlocks occurred.

There are some key constraints we will always need to have in the mobile app - Upgrade management: For many reasons, we will need to force the users to upgrade the app, so that they can use the app smoothly - Feature management: We need to define a way to test and roll out new features efficiently to gather the right feedback before rolling out publically to everyone - Maintenance mode: There will be a time the BE system is entirely down, we need to define an approach so that users still have the great UX.

Building a scalable and modular architecture for a mobile app is crucial for long-term success, as it allows for easier maintenance, updates, and adaptability. Here are some best practices to consider: - Separation of Concerns (SoC) - Model-View-ViewModel (MVVM) Architecture - Dependency Injection - Reusable Components - Loose Coupling - Single Responsibility Principle (SRP) - Use Interfaces and Abstractions - Asynchronous Programming - Optimize Network Calls - Lazy Loading - Testing - Continuous Integration and Deployment (CI/CD) By following these best practices, you can create a scalable and modular architecture that allows your mobile app to evolve and adapt to changing requirements over time.

In ConclusionArchitecture and tech stack can define your app’s failure or success. Hence, choosing the best mobile application architecture is crucial to develop custom mobile apps with great scalability, performance, and security. Your business requirements and user stories help you decide which features to integrate and what type of app structure you need to meet the expectations of all stakeholders.Many factors affect your decisions and not paying attention to every aspect can result in the failure of your project. So, you must consider all aspects, whether security, scalability, performance, etc, when it comes to designing the architecture of your mobile app.

I use Clean Architecture in Flutter! ?? With defined layers: ?? Presentation Layer: Widgets create sleek UIs and handle interactions. ?? Domain Layer: Core of business logic, defining use cases and entities independently. ?? Data Layer: Manages data flow, abstracting sources through repositories. ??? Dependency Rule: Inner layers stay independent, facilitating easy swaps. ?? Benefits: Scalability: Grows seamlessly, integrating new features. Testability: Clear layer separation simplifies unit testing for robustness. Collaboration: Separation of concerns fosters teamwork, enabling parallel work. Clean Architecture is more than a pattern; it's a philosophy for top-notch mobile experiences. ???? #Flutter #CleanArchitecture #MobileDev

The most important design principle to follow in modular app development is separation of concerns. In computer science, separation of concerns is a design principle for separating a computer program into distinct sections. Each section addresses a separate concern, a set of information that affects the code of a computer program. A concern can be as general as "the details of the hardware for an application", or as specific as "the name of which class to instantiate". A program that embodies SoC well is called a modular[1] program. Modularity, and hence separation of concerns, is achieved by encapsulating information inside a section of code that has a well-defined interface.

About the architectural pattern a pragmatic approach is prioritize here that is to say based of the complexity of the app and the category some architecture is more beneficial than other and what fit the most the situation is choose. For example in my case: - If an app main feature will handle a lot of reactivity event driven achitecture is prioritized. - If it's an e-commerce mobile app MVVM will be prioritized

Right choice of developement environment helps to derive the architectural pattern for the mobile application design. The architectural patter differs from individual perspective, whoever has skill on developing the application and has developed similar appliation can help to derive correct architectural pattern. The arctictural design also depends on development environment you are exposed to used to modularise the developement stages to grab the devlopement flow and not to remodel majorly while doing functional implementations.

You should start by Identifing key modules by breaking down your app's functionality into distinct modules with specific responsibilities. Each module should be able to function independently and contribute to the overall app experience. Avoid monolithic structures where code gets intertwined and dependencies become a tangle. Each module should have a well-defined interfaces,and by defining the interface, you can ensure loose coupling. Implement the internal logic of each module with minimal visibility to the outside world. This promotes abstraction and simplifies maintenance. Use private methods and properties to hide implementation details and focus on the module's public interface.

Having a modular approach to the implementation not only ensures the applications scalability but also enhances the scope of management and support to the application. From a well thought back end schema to a resource efficient front end allows the application to have a longer and efficient life span.

The modularity define at its level the ability of the app to not break and this is linked on how good each components are encapsulated and divided in small block with input and output in isolation this give the possibility to test a component alone and easily. To do that when you want to apply modularity make sure to respect some simple satandard especially: - The SRP principle the module should one do 1 and only 1 thing - The OCP principle The module should be close to modification and open to extension

The mobile developer one who skilled with a specific developement environement and you confirmed to use the devlopement environment for mobile applications, then mobile devleloper is like need to recall the experience of his implementation to modularise to meet the proposed Architectural design of the mobile application

Thinking and planning through the complete requirements and challenges will enhance the chances of the application to be a success. Considering the process and user base before jumping into planning also added to it. Having a great hold on the technologies and frameworks available will help you in choosing the right set of technologies and their frameworks. And eventually a correct framework will take care of most of the modularity, standardisation and scalability of the code and application.

If you work with frameworks, this will save you a lot of work in the first place and, in addition, they often already require you to follow best practices. However, it is important to consider the following: - What platform will you be delivering to? You don't want to get stuck and have to start again later with a different framework. - Which language do you feel most comfortable with? If you're developing on your own, it's probably best to develop in a language you already know well. - Do you need to hire staff? What is your budget? Are there professionals in your area who speak the required language/framework?

The choice of tools depend of requirement and constraint: - if the app need to be crossplatform the budget is tied Flutter or React Native might be the appropriate choice - if the app need to use natives features and it's the elephant in the room, better use kotlin for android app development and swift for ios development - if the need does'nt required advanced feature like camera,gallery picture for example better use web responsive app as apk for example and upload it to google playStore.

Choosing experienced tools and frameworks through which requirements could be achieved should be analysed and working with the tool for mobile application developement helps namely like Android studio, MIT apps, Javascript. Knowing the requirement and choosing proper framework help to meet the requirement cohesively

"Navigating the Mobile App Tool Landscape: A Comprehensive Guide" Explore the diverse landscape of mobile app development tools and frameworks. Discuss their strengths, weaknesses, and use cases. Provide insights into how developers can navigate this ecosystem to make informed decisions based on their project requirements.

The above are good, other than that from the developer point of view, all possible high level testing needs to be taken care, since the developer knows all possible issues which occur most of the time. In rare cases, the test case of multiple possibilities alos helps to save the major issues.

The time (value) spent for testing is actually invested , you will get it back several times more by avoiding defects in production.

While design the architectural pattern of the development , its important to point out the contraints of the applications and flow with better alternative at time of deign and likely to be fixed. While testing , its good practice to read the High Level Design document of the testable application to focus on the lines of the implementations to get tested and test as per defined alternatives and functional. Good to start testing on requirement outcomes with modular aspects like Unit, Functional and System testing incase the mobile application used various flows for achieveing the requirement. In case uses lesser intensive architecture code flow, Testing approach can be refractor as per the need of the outcomes with testing requiremnts.

Break your app into modular components. Each module should encapsulate a specific feature or functionality. This modular approach improves maintainability, allows for independent development and testing, and facilitates code reuse. Maintain clear and up-to-date documentation for your architecture, APIs, and codebase. This is essential for onboarding new developers, collaborating effectively, and understanding the overall system.

I agree with the above, in addition to that keep your architecture of the application as highly flexible in terms of bandwidth, number of users logged in and other general parameters. Improve the architecture by getting feedback about current applications as well as based on the testing suggestion.

One very important thing when building any kind of system is proper API design. APIs in software architecture are like the nervous system in our body. Just as the nervous system enables communication and coordination between different parts of the body, APIs allow different software components to communicate and work together. They enable integration and interaction between different systems and services, facilitating the flow of information and functionality across the software ecosystem. This interconnectedness, much like the nerves in a body, is vital for the correct operation of software systems. Consider these points when designing your APIs: 1) Simplicity & clarity. 2) Consistency & predictability. 3) Robust error handling.

I think that if you build using a serverless architecture, it's the easiest if scalability is a top priority. It also encourages writing loosely dependent code modules and encapsulate them as a function (e.g. Azure function, Google Cloud function, Lambda function of AWS).

In my perspective, a good scalable API layer helps in scaling mobile apps, keeping the service layer lite and having good DDD principles applied to your API design will allow application's functional management and subsequent extensions clean. Following an asynchronous architecture will help in managing the apps responsiveness which will help in any data driven apps.

An essential practice is to incorporate -meaning building in- accessibility right from the start. Designing for a target audience often means creating a non-inclusive system. Avoid this pitfall by broadening your perspective on the personas using the system.

You need to think if your services are entirely serverful or serverless, and how you will containerize that. Serverless is not a "silver bullet" for scalability and performance, but when used rightly, it can easily scale part of your system. Also, it is important to look at some books about Clean Architecture, Clean Code, and Serveless vs Serverful.
