Layered Architecture

Layered Architecture - WIP

Layered architecture is a design pattern that organizes code into well-defined layers, each with a specific responsibility.

Main Layers

1. Presentation (UI)

   • React components
   • UI hooks
   • Styles and layouts

2. Business Logic

   • Use cases
   • Business rules
   • Data transformation

3. Data

   • API services
   • Repositories
   • State management

Directory Structure

src/
├── app/                 # App shell (router, providers)
├── features/           # Feature-specific logic
│   ├── cart/          # Shopping cart
│   └── product/       # Product catalog
├── entities/          # Entities and services
│   └── product/       # Product service
└── shared/            # Shared components and utilities

Example: Mini Commerce

In the following sections, we will implement a practical example of an online store using layered architecture.

Next Steps

• Project Structure
• Feature Implementation
• State Management
