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
