🛠 Technical Implementation Strategy

Component Development Workflow

1. Component Scaffold Generation

// Template structure for each new component
src/
├── lib.rs          // Framework integration & public API
├── default.rs      // Default theme variant
├── new_york.rs     // New York theme variant  
├── types.rs        // Props and component types
└── tests.rs        // Unit tests

2. Framework-Specific Implementation

// Yew implementation pattern
#[function_component]
pub fn Button(props: &ButtonProps) -> Html {
    let classes = use_button_classes(props);
    html! { <button class={classes}>{&props.children}</button> }
}

// Leptos implementation pattern  
#[component]
pub fn Button(props: ButtonProps) -> impl IntoView {
    let classes = create_button_classes(props);
    view! { <button class=classes>{props.children}</button> }
}

3. Registry Integration

// Add component to registry_ui.rs
RegistryEntry {
    name: "checkbox".into(),
    r#type: RegistryItemType::Ui,
    description: Some("Checkbox input control".into()),
    dependencies: Some(vec!["web-sys".into()]),
    files: Some(vec![
        RegistryItemFile {
            path: "ui/checkbox.rs".into(),
            r#type: RegistryItemType::Ui,
            target: None,
        }
    ]),
    category: Some("forms".into()),
}
