# Architecture
This section covers the technical architecture, design decisions, and implementation details of the Leptos ShadCN UI library.
## 🏗️ Architecture Overview
The Leptos ShadCN UI library is built on several key architectural principles:
- **Component-Based**: Modular, reusable UI components
- **Type-Safe**: Full Rust type safety with compile-time checks
- **Reactive**: Built on Leptos signals for reactive updates
- **Accessible**: WCAG 2.1 compliant components
- **Customizable**: Flexible theming and styling system
## 📁 Structure
### [Design Decisions](./design-decisions/)
Architecture Decision Records (ADRs) documenting key technical choices:
- TDD-first approach
- Testing pyramid strategy
- API contracts and testing
- Package management strategy
- Leptos versioning strategy
- Rust coding standards
### [Migration Guides](./migration-guides/)
Guides for upgrading between versions:
- Leptos 0.8.8 migration
- Signal integration updates
- Breaking changes documentation
### [Coverage Analysis](./coverage/)
Test coverage documentation and analysis:
- Coverage remediation plans
- Tool recommendations
- Achievement summaries
- Zero coverage priority plans
### [Performance](./performance/)
Performance analysis and optimization:
- Benchmarks and metrics
- Performance audit results
- Optimization strategies
- Load testing results
## 🔧 Technical Details
### Core Technologies
- **Leptos**: Reactive web framework
- **Tailwind CSS**: Utility-first styling
- **WebAssembly**: Client-side execution
- **Rust**: Type-safe systems programming
### Component Architecture
- **Props**: Type-safe component properties
- **Signals**: Reactive state management
- **Events**: Event handling and callbacks
- **Styling**: CSS-in-Rust approach
## 📊 Quality Metrics
