To: `/Users/byeongcheolryu/codebridgex/sam_project/sam-next/sma-next-project/sam-react-prod` (Next.js)

## Components Migrated

### Dashboard Components (src/components/business/)
1. **Dashboard.tsx** - Main dashboard router with lazy loading
2. **CEODashboard.tsx** - CEO role dashboard

4. **WorkerDashboard.tsx** - Worker role dashboard
5. **SystemAdminDashboard.tsx** - System Admin dashboard
6. **SalesLeadDashboard.tsx** - Sales Lead dashboard

### Layout Components
1. **DashboardLayout.tsx** (src/layouts/) - Main layout with sidebar, header, and role switching

### Supporting Components
1. **Sidebar.tsx** (src/components/layout/) - Navigation sidebar component

### Hooks
1. **useUserRole.ts** - Hook for managing user roles
2. **useCurrentTime.ts** - Hook for current time display

### State Management (src/store/)
1. **menuStore.ts** - Zustand store for menu state
2. **themeStore.ts** - Zustand store for theme management
3. **demoStore.ts** - Demo data store

### UI Components
1. **calendar.tsx** - Calendar component
2. **sheet.tsx** - Sheet/drawer component
3. **chart-wrapper.tsx** - Chart wrapper component

## Dependencies Installed
```json
{
  "zustand": "^latest",
  "recharts": "^latest",
  "react-day-picker": "^8",
  "date-fns": "^latest",
  "@radix-ui/react-dropdown-menu": "^latest",
  "@radix-ui/react-dialog": "^latest",
  "@radix-ui/react-checkbox": "^latest",
  "@radix-ui/react-switch": "^latest",
  "@radix-ui/react-popover": "^latest"
}
```

## Key Adaptations for Next.js

### 1. Router Changes
- **Before**: `react-router-dom` with `useNavigate()` and `<Outlet />`
- **After**: Next.js with `useRouter()`, `usePathname()` from `next/navigation`

### 2. Client Components
- Added `'use client'` directive to:
  - `src/layouts/DashboardLayout.tsx`
  - `src/components/business/Dashboard.tsx`
  - All dashboard role components

### 3. Layout Pattern
- **Before**: `<Outlet />` for nested routes
- **After**: `{children}` prop pattern

### 4. Props Interface
Added `DashboardLayoutProps` interface:
```typescript
interface DashboardLayoutProps {
  children: React.ReactNode;
}
```

## Role-Based Dashboard System

The system supports 5 user roles:
1. **CEO** - Full dashboard with business metrics
2. **ProductionManager** - Production-focused dashboard
3. **Worker** - Simple work performance dashboard
4. **SystemAdmin** - System management dashboard
5. **Sales** - Sales and leads dashboard

Role switching is handled via:
- localStorage user data
- `useUserRole()` hook
- Real-time updates via `roleChanged` event
- Dynamic menu generation based on role

## Known Issues / Future Work

### ESLint Warnings
Many components have ESLint warnings for:
- Unused variables
- Unused imports
- TypeScript `any` types
- Missing type definitions

These need to be cleaned up but don't affect functionality.

### Missing Features
- Some business components were copied but may need additional UI components
- Route definitions in `app/` directory need to be created
- API integration may need updates for Next.js API routes

## Next Steps

1. Create dashboard routes in `src/app/dashboard/`
2. Clean up ESLint errors and warnings
3. Test all role-based dashboards
4. Add missing UI components as needed
5. Update API calls for Next.js API routes
6. Add authentication guards
7. Test role switching functionality

2. Navigate to `/dashboard`
3. Test role switching via dropdown
4. Verify each dashboard loads correctly
5. Check responsive design (mobile/desktop)
