# UI Component Migrator Skill

Migrates UI components between different frameworks, handling structure translation, state management conversion, and style migration.

## Purpose

Enable UI framework migration for:
- Component structure translation
- State management migration
- Lifecycle method conversion
- Event handling transformation
- Style migration

## Capabilities

### 1. Component Structure Translation
- Convert component syntax
- Transform templates
- Migrate component props
- Handle slots/children

### 2. State Management Migration
- Convert local state
- Migrate global state (Redux/Vuex/etc)
- Transform state updates
- Handle computed properties

### 3. Lifecycle Method Conversion
- Map lifecycle methods
- Convert to hooks/composition API
- Handle initialization
- Transform cleanup logic

### 4. Event Handling Transformation
- Convert event bindings
- Transform handlers
- Migrate custom events
- Handle event modifiers

### 5. Style Migration
- Convert CSS-in-JS
- Migrate scoped styles
- Transform CSS modules
- Handle theme systems

### 6. Test Migration
- Convert component tests
- Update test utilities
- Transform mocking
- Migrate snapshots
