- Node.js 18+
- Python 3.x

### Local Development

```bash
# Clone the repository
git clone https://github.com/your-username/leptos-shadcn-ui.git
cd leptos-shadcn-ui

# Install dependencies
npm install

# Build the demo
cd examples/comprehensive-demo
wasm-pack build --target web --out-dir pkg

# Serve locally
python3 -m http.server 8001
```

Visit `http://localhost:8001` to see the demo!

### Running Tests

```bash
# Install Playwright
npx playwright install
