# Migration Plan: Vue shadcn → Next.js shadcn

## Project Overview
Migration dari AutoLight System (ALS) WebClient dari Vue 3 + shadcn-vue ke Next.js 15 + shadcn/ui.

## Current Structure Analysis

### WebClient_Old (Vue Application)
- **Framework**: Vue 3 + TypeScript + Vite
- **UI Library**: shadcn-vue + radix-vue
- **State Management**: VueUse composables
- **Routing**: Vue Router
- **API**: Axios
- **Features**: AutoLight device control, real-time polling, dark mode

### WebClient (Next.js - Target)
- **Framework**: Next.js 15 + TypeScript
- **UI Library**: shadcn/ui + Radix UI
- **State Management**: React Context (to be implemented)
- **Routing**: App Router
- **API**: Native fetch (to be implemented)

## 1. Core Architecture Migration

### State Management Conversion
```typescript
// Vue (VueUse)
const alsDataStateManagement = createGlobalState(() => {
    const deviceNameALS = ref('');
    const modeALS = ref();
    // ...
});

// React (Context + hooks)
const ALSContext = createContext();
const useALSData = () => {
    const [deviceName, setDeviceName] = useState('');
    const [mode, setMode] = useState();
    // ...
};
```

### Component Structure Migration
- **MainPage.vue** → `app/page.tsx`
- **ModernTheme.vue** → `app/components/ModernTheme.tsx` 
- **ClassicTheme.vue** → `app/components/ClassicTheme.tsx`
- **Settings.vue** → `app/settings/page.tsx`
- **SettingsTema.vue** → `app/settings/theme/page.tsx`
- **SettingsUpdate.vue** → `app/settings/update/page.tsx`

## 2. API Migration Strategy

### Current Vue Implementation
```typescript
// axios-based polling
async function fetchData() {
    const ch = await fetchDataDeviceChannel();
    const deviceName = await fetchDataDeviceName();
    // Update reactive state
    alsData.deviceNameALS.value = deviceName;
}
setInterval(fetchData, 2000);
```

### Target React Implementation
```typescript
// fetch-based with useEffect
const useALSPolling = () => {
    useEffect(() => {
        const interval = setInterval(async () => {
            const response = await fetch('/get/device/ch');
            const data = await response.json();
            setDeviceChannel(data);
        }, 2000);
        return () => clearInterval(interval);
    }, []);
};
```

## 3. Routing Migration

### Vue Router Structure
```typescript
const routes = [
    { path: '/', component: MainPage },
    { path: '/settings', component: Settings,
        children: [
            { path: 'tema', component: SettingsTema },
            { path: 'update', component: SettingsUpdate }
        ]
    }
];
```

### Next.js App Router Structure
```
app/
├── page.tsx                    # MainPage (/)
├── layout.tsx                  # Root layout
├── settings/
│   ├── page.tsx               # Settings main (/settings)
│   ├── layout.tsx             # Settings layout
│   ├── theme/
│   │   └── page.tsx           # SettingsTema (/settings/theme)
│   └── update/
│       └── page.tsx           # SettingsUpdate (/settings/update)
└── components/
    ├── ModernTheme.tsx
    ├── ClassicTheme.tsx
    └── ui/                    # shadcn/ui components
```

## 4. UI Components Migration

### shadcn-vue → shadcn/ui Mapping
- `@/components/ui/button` → `@/components/ui/button`
- `@/components/ui/card` → `@/components/ui/card`
- `@/components/ui/drawer` → `@/components/ui/drawer`
- `@/components/ui/input` → `@/components/ui/input`
- `@/components/ui/label` → `@/components/ui/label`
- `radix-vue` → `@radix-ui/react`
- `lucide-vue-next` → `lucide-react`

### Required shadcn/ui Components
- Button, Card, Drawer, Input, Label
- RadioGroup, Select, Slider, Textarea
- Alert, AlertDialog, Badge, Checkbox
- AspectRatio, Avatar, Sheet, Spinner, Table

## 5. Key Features to Preserve

### AutoLight Device Integration
- Real-time device status polling (2-second intervals)
- Mode switching functionality
- Delay adjustment controls
- Channel management
- Device name/serial configuration

### API Endpoints (Maintain Compatibility)
- `/get/device/ch` - Get device channels
- `/get/delay` - Get current delay
- `/get/device/name` - Get device name
- `/get/device/serial` - Get serial number
- `/get/mode` - Get current mode
- `/set/mode?value=X` - Set device mode

### UI/UX Features
- Dark mode support
- Responsive design
- Modern/Classic theme switching
- Settings management
- Real-time status updates

## 6. Implementation Phases

### Phase 1: Foundation Setup
1. Install required shadcn/ui components
2. Set up React Context for state management
3. Create basic component structure
4. Implement API utility functions

### Phase 2: Core Components
1. Migrate MainPage functionality
2. Convert ModernTheme and ClassicTheme
3. Implement device polling logic
4. Set up routing structure

### Phase 3: Settings System
1. Migrate Settings components
2. Implement theme management
3. Add update functionality
4. Test hardware integration

### Phase 4: Polish & Testing
1. Ensure feature parity
2. Performance optimization
3. Hardware compatibility testing
4. UI/UX refinement

## 7. Technical Considerations

### Dependencies to Add
```json
{
  "zustand": "^4.x",           // Advanced state management
  "swr": "^2.x",               // Data fetching hooks
  "@radix-ui/react-*": "^1.x", // UI primitives
  "class-variance-authority": "^0.7.x",
  "tailwind-merge": "^2.x"
}
```

### Development Guidelines
- Maintain 100% feature parity
- Preserve existing API contract
- Keep responsive design intact
- Ensure hardware compatibility
- Follow Next.js 15 best practices
- Use TypeScript strictly
- Implement proper error handling

## 8. Testing Strategy
- Component unit tests
- API integration tests
- Hardware communication tests
- Cross-browser compatibility
- Mobile responsiveness
- Performance benchmarks
