📋 Current Status Summary

Current Status:

• Leptos: 47/51 components (92% coverage) ✅ Near Complete!
• Target: 51/51 components (100% coverage) for Leptos framework

Updated Priority Matrix:

🎯 Leptos: Final 4 Components (92% → 100%)

• avatar, data-table, chart, resizable, sidebar, sonner, typography

✅ Completed Components (47/51)

Form & Input: checkbox, radio-group, select, combobox, form, date-picker, input-otp, slider, toggle, switch, input, label, textarea Navigation: navigation-menu, menubar, tabs, breadcrumb, command, context-menu, hover-card Overlay: dialog, alert-dialog, sheet, drawer, dropdown-menu, popover, tooltip, toast
Layout: accordion, collapsible, scroll-area, separator, aspect-ratio Display: calendar, carousel, progress, skeleton Advanced: pagination, table, button, card, alert, badge, utils

🎯 Implementation Phases

Phase 1: Foundation Enhancement (1-2 weeks) ✅ Infrastructure & Tooling

Week 1: Registry & Infrastructure

# Enhance component registry system
- Optimize registry_ui.rs with complete component definitions
- Implement dependency resolution system
- Add theme variant management
- Improve code generation pipeline

Week 2: Testing & Quality Infrastructure

# Enhance testing and quality systems
- Automated testing integration
- Component validation framework
- Performance benchmarking tools
- Documentation generation system

Deliverable: Robust foundation for rapid component development

Phase 2: Leptos Completion (2-3 weeks) ✅ 92% → 100%

Week 3-4: Final Components for Leptos

# Complete shadcn/ui spec for Leptos
- avatar: User profile image component
- data-table: Advanced table with sorting, filtering, pagination
- chart: Data visualization components  
- resizable: Resizable panel layout system
- sidebar: Navigation sidebar component
- sonner: Toast notification system (modern alternative)
- typography: Text styling and layout utilities

Deliverable: Leptos reaches 51/51 components (100% shadcn/ui coverage)

Phase 3: Advanced Features & Optimization (2-3 weeks)

Week 5-6: Advanced Features

# Enhanced functionality
- Advanced theme system
- Animation library integration
- Accessibility enhancements
- Performance optimizations

Week 7: Quality Assurance & Documentation

Deliverable: Production-ready, fully-featured Leptos shadcn/ui ecosystem

🛠 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. Registry Integration

// Add component to registry_ui.rs
RegistryEntry {
    name: "avatar".into(),
    r#type: RegistryItemType::Ui,
    description: Some("User profile image component".into()),
    dependencies: Some(vec!["web-sys".into()]),
    files: Some(vec![
        RegistryItemFile {
            path: "ui/avatar.rs".into(),
            r#type: RegistryItemType::Ui,
            target: None,
        }
    ]),
    category: Some("display".into()),
}
