A modern, maintainable, and scalable demo version of the DigiKala shopping application built with Jetpack Compose, following best practices of Clean Architecture, MVVM, and SOLID principles.
This project showcases the use of modern Android development tools and design patterns. The goal is to demonstrate a clean, modular, and production-ready setup using cutting-edge libraries and architecture.
| Category | Technology / Tool |
|---|---|
| Language | Kotlin |
| UI Toolkit | Jetpack Compose |
| Navigation | Compose Navigation |
| Image Loading | Coil |
| Dependency Injection | Hilt |
| Networking | Retrofit + OkHttp |
| Local Storage | Room Database, DataStore |
| Architecture Pattern | MVVM + Clean Architecture |
| Reactive Flow | Kotlin Coroutines, Flow |
This project is structured using Clean Architecture principles. The layers are clearly separated to enforce a single responsibility and support scalability and testability:
Presentation (UI Layer - Jetpack Compose) ↓ ViewModel (State Management - Kotlin Flow) ↓ UseCase (Business Logic) ↓ Repository (Interface Abstraction) ↓ Data Layer (Remote APIs - Retrofit, Local DB - Room, Preferences - DataStore)
Each layer is decoupled and testable. Dependency Injection is handled via Hilt across all components.
