## 2. Architecture Overview

### Layout Hierarchy

```
app/layout.js (Server Component — root HTML, fonts, metadata)
  └── app/ClientLayout.js (Client Component — 804 lines)
        ├── <NotificationsProvider>     (context)
        │   └── <FavoritesProvider>     (context)
        │       └── <main>{children}</main>
        ├── <BottomNav />               (mobile, authenticated only)
        └── <NotificationHandler />     (FCM push notifications)
```

- **No nested layouts** — flat route structure
- **No `middleware.js`** — all route protection is client-side only
- Nav bar hidden on auth pages (`/login`, `/register/*`, `/blocked`, `/forgot-password`, `/auth/choose-role`)

### Data Flow Pattern

```
Page (useEffect on mount)
  → API call (apiFetch from app/utils/api.js)
    → AuthService.getToken() → Authorization: Bearer <JWT>
    → fetch() to https://45.93.137.91.nip.io/api/{endpoint}
    → Response: auto-unwrap { data: ... } envelope
    → Return parsed data or throw on non-ok
  → Component state (useState)
  → Render UI with Tailwind classes
```

---

## 3. API Layer

**File:** `app/utils/api.js` (1198 lines — 370 commented legacy + 828 active)
**Ratings API:** `app/utils/ratings.js` (separate file with own `apiFetch`)

---

## 4. State Management

### Context Providers

| Context | File | State | Consumers | Status |
|---------|------|-------|-----------|--------|
| **FavoritesProvider** | `app/contexts/FavoritesContext.js` | `favorites[]`, `isLoading` | `FloatingSidebar`, `/favorites`, `/properties`, `/property/[id]` | ✅ Active |
| **NotificationsProvider** | `app/contexts/NotificationsContext.js` | `notifications[]`, `unreadCount`, `isLoading` | `BottomNav`, `FloatingSidebar` | ✅ Active |
| **PropertyContext** | `app/contexts/PropertyContext.js` | `properties[]`, `loading`, `error` | None | ❌ Orphaned (never mounted) |
| **PropertyContext** | `app/utils/PropertyContext.js` | Same as above | None | ❌ Orphaned duplicate |

### localStorage Keys (10 actively written, ~5 legacy read-only)

| Key | Data | Written By | Read By |
|-----|------|------------|---------|
| `auth_token` | JWT string | `AuthService.addToken()` | `AuthService.getToken()`, `firebase.js` |
| `cached_user` | User profile JSON | `AuthService.cacheUser()` | `AuthService.getCachedUser()` |
| `language` | "en" or "ar" | `ClientLayout.js` | `ClientLayout.js` |
| `sweethome_onboarding_completed` | "true" | `/onboarding/page.js` | `/onboarding/page.js` |
| `ownerProperties` | Properties array JSON | `/owner/properties/page.js` | `/owner/calendar/page.js` |
| `ownerBookings` | Bookings array JSON | `/owner/bookings/page.js` | `/owner/bookings/page.js` |
| `ownerProfitsTable` | Profit data JSON | `/owner/profits/page.js` | `/owner/profits/page.js` |
| `userProfile` | Profile form data JSON | `/profile/page.js` | `/profile/page.js` |
| `userAvatar` | Base64 data URL | `/profile/page.js` | `/profile/page.js` |
| `token`, `accessToken`, `authToken` | (legacy reads only) | — | `/settings`, `/payments`, `/reservations` |

### Auth Flow

```
Login (app/login/page.js)
  → loginWithEmail() / loginWithPhone()
  → authFetch(POST /Auth/LogInWithEmail, { credential, password, device: 0 })
  → 200: AuthService.addToken(token) → localStorage.setItem('auth_token', token)
  → 206: OTP required → sendEmailOTP() → verifyEmail(code) → get final token
  → AuthService.cacheUser(user) → localStorage.setItem('cached_user', ...)
  → router.push('/')

ClientLayout.js (every page navigation)
  → AuthService.getUser() → decode JWT payload (base64 atob)
  → setUser({ name, email, phone, role: isOwner() ? 'owner' : 'customer' })
  → UI branches on user.role (show owner nav / customer nav / guest nav)

Page-level checks
  → Each protected page independently calls:
    AuthService.isAuthenticated() → else router.push('/login')
    AuthService.isOwner() → else router.push('/')
```

## 5. Component Architecture

### Component Inventory (14 reusable components)

### Largest Page Files

| Rank | File | Lines | Complexity |
|------|------|-------|------------|
| 1 | `api.js` | 1198 | 60+ functions, 4 fetch helpers, 370 lines commented |
| 2 | `PropertyDetail.js` | 1743 | 56 imports, 8+ state vars, booking calendar, image gallery, owner check, ratings, map |
| 3 | `owner/properties/page.js` | 2057 | CRUD + modals + localStorage caching + API calls |
| 4 | `ClientLayout.js` | 804 | Nav (desktop+mobile), user menu, language switcher, context providers |

| 6 | `app/page.js` (Home) | 623 | Property fetching, multi-filter, hero, map, feature cards |

---

## 6. Key Patterns

### Data Fetching (4 Patterns)

| Pattern | Usage | Found In |
|---------|-------|----------|
| `useEffect` + `useState` | ~90% of pages | Most pages |
| Context-level fetch | 2 providers | `FavoritesContext`, `NotificationsContext` |
| localStorage cache | Owner dashboards | `owner/bookings`, `owner/calendar`, `owner/profits` |
| Mock data fallback | 3 owner pages | `owner/bookings`, `owner/calendar`, `owner/profits` |

### Styling

- 100% Tailwind CSS v4 (utility classes, no CSS modules)
- Custom `globals.css`: Madani Arabic fonts (9 weights), Leaflet overrides, keyframe animations
- Color palette: `amber-500/600` (primary), `#ede6e6` (bg), `#156874` (accent teal)
- RTL-first with dynamic LTR switching via `currentLanguage` state

### Animations (Framer Motion v12.29.2)

- `initial/animate` opacity + y/x translations (section reveals)
- `whileHover`/`whileTap` scale (buttons, interactive elements)
- `AnimatePresence` (property popups, user menus)
- `whileInView` + `viewport` (scroll-triggered animations on home page)
- `staggerChildren` (hero text)
- Spring transitions `{ type: "spring", damping: 25, stiffness: 300 }`

### Form Handling

- **All forms**: Controlled `useState` — no React Hook Form, Formik, or `useReducer`
- **Validation**: Inline `value === 0 && <p className="text-red-500">مطلوب</p>`
- **No form libraries** — all hand-rolled

### Responsive Breakpoints

| Breakpoint | Layout |
|------------|--------|
| Default (mobile) | Single column, BottomNav, hamburger menu |
| `md:` (768px) | Desktop nav, 2-3 column grids |
| `lg:` (1024px) | PropertyDetail sidebar, 3-column grids |

## 7. Owner Pages Analysis (Dashboard Section)

| Route | File | Lines | Status | Data Source |
|-------|------|-------|--------|-------------|
| `/owner/properties` | `owner/properties/page.js` | 2057 | ✅ Active | API (`getMyRentListings`, `getMySaleListings`) + localStorage cache |
| `/owner/properties/add` | `owner/properties/add/page.js` | 700+ | ✅ Active | API (`addRentProperty`, `addSaleProperty`, `uploadPicture`) |
| `/owner/reservations` | `owner/reservations/page.js` | 1400+ | ❌ Commented out | Mock data (commented) |
| `/owner/bookings` | `owner/bookings/page.js` | 560+ | ⚠️ Demo | localStorage mock data only |
| `/owner/calendar` | `owner/calendar/page.js` | 580+ | ⚠️ Demo | localStorage mock data only |
| `/owner/profits` | `owner/profits/page.js` | 600+ | ⚠️ Demo | localStorage mock data only |
| `/owner/account-book` | `owner/account-book/page.js` | 500+ | ✅ Active | API (`getOwnerStatistics`) |

---

## 8. Admin Functionality

| Component | Status | Data Source |
|-----------|--------|-------------|
| BookingRequests | ✅ Active | Real API (`getReservations`, `adminConfirmDeposit`) |
| Users | ❌ Not implemented | — |
| Properties | ❌ Not implemented | — |
| LedgerBook | ⚠️ Mock only | 3 hardcoded mock transactions |
| Dashboard | ❌ Not implemented | — |

Designed for internal admin use at `/admin` — tabs for Bookings/Users/Properties/Ledger/Dashboard.

---

## 9. Known Technical Debt

### Dead Code

| File | Dead Lines | Issue |
|------|-----------|-------|
| `api.js` | Lines 1-370 (370 lines) | Entire legacy version commented out |
| `StarRating.js` | Lines 1-93 (93 lines) | Old framer-motion version commented out |
| `PropertyRatingList.js` | ~150 lines | Old version commented out |
| `PropertyRatingForm.js` | ~220 lines | Old version commented out |
| `contexts/PropertyContext.js` | Entire file | Never mounted |
| `utils/PropertyContext.js` | Entire file | Duplicate orphan |

### Code Duplication

| Pattern | Files | Description |
|---------|-------|-------------|
| Leaflet maps | 3 separate files | `PropertyMapWithMarkers.js`, `home/PropertyMap.js`, `property/PropertyMap.js` — all setup Leaflet identically |
| Rating forms | `PropertyRatingForm.js` (317) + `CustomerRatingForm.js` (92) | ~75% code overlap; both define identical `RatingField` inline |
| formatCurrency | 4+ locations | Scattered across files with slightly different logic |
| Image URL building | 4+ locations | Different implementations for same task |
| Notifications page | `/notifications/page.js` vs `NotificationsContext` | Page duplicates all context state/logic |

### Architecture Issues

| Issue | Impact |
|-------|--------|
| No middleware.js | All route protection is client-side only |
| JWT in localStorage | XSS-vulnerable token storage |
| Client-side role checks | Users can modify JWT to elevate privileges |
| Owner pages use mock data | `/owner/bookings`, `/owner/calendar`, `/owner/profits` are demo-only |
| 3 unused UI libraries | DaisyUI, Flowbite, Yandex Maps imported but never used |
| No TypeScript | 112 JS files, no type safety |
| No ESLint | No linting configured |
| No testing framework | Zero tests |
| Flat route structure | No nested layouts; all pages share root layout |
| Active console.log | ~30+ files with console.log statements (security risk) |
