Development Process

Architecture Overview

The application follows a modular, component-based architecture with clear separation of concerns:

src/
├── components/          # Reusable UI components
│   ├── image-composer/  # Image compression feature
│   ├── image-enhancer/  # Image enhancement feature
│   └── ui/             # Base UI components
├── hooks/              # Custom React hooks
├── lib/                # Core business logic
├── pages/              # Route components
├── types/              # TypeScript type definitions
└── utils/              # Utility functions

Development Workflow

1. Feature Development: Each feature is developed as a separate module with its own components, hooks, and utilities
2. Type Safety: Comprehensive TypeScript implementation ensures code reliability
