+# Delivery List Filter & Sort Implementation Guide
+
+## Overview
+This document outlines the implementation of delivery list filter and sort controls for the SwiftChain frontend application. The implementation follows a strict **Component → Hook → Service** layered architecture and maintains filter state through URL query parameters for persistent state across page refreshes.
+
+## Architecture
+

+```
+
+## Components & Hooks
+
+### 1. DeliveryFilters Component (`features/deliveries/components/DeliveryFilters.tsx`)
+
+**Responsibility**: Renders the UI for filtering and sorting deliveries.
+
+**Features**:
+- Search by Tracking ID (with debounce on blur/Enter)
+- Filter by Status dropdown
+- Sort by Date dropdown
+- Display active filters with visual badges
+- Clear all filters button
+
+**Props**: None (uses `useDeliveryFilters` hook internally)
+
+**Example Usage**:
+```tsx
+import { DeliveryFilters } from '@/features/deliveries/components/DeliveryFilters';
+
+export function DeliveryPage() {
+  return (
+    <div>
+      <DeliveryFilters />
+      {/* Rest of component */}
+    </div>
+  );
+}
+```
+
+### 2. useDeliveryFilters Hook (`features/deliveries/hooks/useDeliveryFilters.ts`)
+
+**Responsibility**: Manages filter state through URL query parameters and provides methods to update filters.
+
+**Features**:
+- Reads filter state from URL query parameters
+- Provides `updateFilters` method to update one or more filters
+- Provides `clearFilters` method to reset all filters
+- Automatically syncs state with URL for persistence
+- Returns `hasActiveFilters` flag for UI feedback
+
+**Returns**:
+```typescript
+{
+  search?: string;           // Search query
+  status?: string;           // Delivery status filter
+  sortBy?: 'date-asc' | 'date-desc'; // Sort order
+  hasActiveFilters: boolean; // Whether any filters are active
+  updateFilters: (params: Partial<DeliveryFilterParams>) => void;
+  clearFilters: () => void;
+}
+```
+
+**Example Usage**:
+```tsx
+const { search, status, sortBy, updateFilters, clearFilters, hasActiveFilters } = useDeliveryFilters();
+
+// Update individual filter
+updateFilters({ search: 'TRK12345' });
+
+// Update multiple filters
+updateFilters({ status: 'DELIVERED', sortBy: 'date-desc' });
+
+// Clear all filters
+clearFilters();
+```
+
+### 3. useDeliveries Hook (`hooks/useDeliveries.ts`)
+
+**Responsibility**: Fetches deliveries from the backend with optional filter parameters.
+
+**Features**:
+- Integrates with React Query for caching and state management
+- Accepts optional filter parameters
+- Manages loading and error states
+- Automatic query key invalidation when filters change
+
+**Returns**:
+```typescript
+{
+  data?: Delivery[];
+  isLoading: boolean;
+  error?: Error;
+}
+```
+
+**Example Usage**:
+```tsx
+const { search, status, sortBy } = useDeliveryFilters();
+const { data, isLoading, error } = useDeliveries({
+  search,
+  status,
+  sortBy,
+});
+```
+
+## Service Integration
+
+### deliveriesService (`services/deliveries.service.ts`)
+
+**Responsibility**: Handles API communication with the backend.
+
+**Methods**:
+
+#### `getDeliveries(filters?: DeliveryFilterParams): Promise<Delivery[]>`
+Fetches deliveries from the backend with optional filters.
+
+**Parameters**:
+```typescript
+{
+  search?: string;           // Search by tracking number
+  status?: string;           // Filter by status
+  sortBy?: 'date-asc' | 'date-desc'; // Sort order
+}
+```
+
+**Example**:
+```typescript
+// Fetch all deliveries
+await deliveriesService.getDeliveries();
+
+// Fetch with filters
+await deliveriesService.getDeliveries({
+  search: 'TRK12345',
+  status: 'IN_TRANSIT',
+  sortBy: 'date-desc'
+});
+```
+
+#### `getDeliveryById(id: string): Promise<Delivery>`
+Fetches a specific delivery by ID.
+
+## Type Definitions
+
+### FilterParams Type (`types/filters.ts`)
+
+```typescript
+interface DeliveryFilterParams {
+  search?: string;
+  status?: string;
+  sortBy?: 'date-asc' | 'date-desc';
+}
+
+interface FilterState extends DeliveryFilterParams {
+  hasActiveFilters: boolean;
+}
+```
+
+## URL Query Parameters
+
+Filter state is persisted through URL query parameters. Here are the supported parameters:
+
+| Parameter | Type | Example |
+|-----------|------|---------|
+| `search` | string | `?search=TRK12345` |
+| `status` | string | `?status=DELIVERED` |
+| `sortBy` | string | `?sortBy=date-desc` |
+
+**Combined Example**:
+```
+/deliveries?search=TRK12345&status=IN_TRANSIT&sortBy=date-desc
+```
+
+## API Endpoint Contract
+
+The backend API should support the following endpoint:
+
+```
+GET /api/deliveries?search={search}&status={status}&sortBy={sortBy}
+```
+
+### Request Query Parameters
+- `search` (optional): Search deliveries by tracking number
+- `status` (optional): Filter by delivery status (PENDING, ACCEPTED, IN_TRANSIT, DELIVERED, CANCELLED)
+- `sortBy` (optional): Sort deliveries (date-asc, date-desc)
+
+### Response
+```json
+[
+  {
+    "id": "uuid",
+    "trackingNumber": "TRK12345",
+    "senderId": "uuid",
+    "driverId": "uuid",
+    "status": "IN_TRANSIT",
+    "origin": "Nairobi",
+    "destination": "Mombasa",
+    "escrowStatus": "LOCKED",
+    "amount": 100.00,
+    "createdAt": "2024-01-01T00:00:00Z",
+    "updatedAt": "2024-01-01T00:00:00Z"
+  }
+]
+```
+
+## Status Values
+
+- `PENDING`: Delivery request created, awaiting driver acceptance
+- `ACCEPTED`: Driver has accepted the delivery
+- `IN_TRANSIT`: Package is in transit
+- `DELIVERED`: Package has been delivered
+- `CANCELLED`: Delivery was cancelled
+
+## Data Flow Diagram
+
+```
+User interacts with DeliveryFilters component
+        ↓
+updateFilters() called with new filter values
+        ↓
+useDeliveryFilters updates URL query parameters
+        ↓
+URL changes, triggering component re-render
+        ↓
+useDeliveryFilters hook reads new query params
+        ↓
+Filter state updates
+        ↓
+useDeliveries hook receives new filters
+        ↓
+Query key changes, triggering new fetch
+        ↓
+deliveriesService.getDeliveries() called with filters
+        ↓
+API request sent with query parameters
+        ↓
+Backend returns filtered results
+        ↓
+React Query caches results
+        ↓
+Component re-renders with new data
+```
+
+## Integration with DeliveryList
+
+The `DeliveryList` component integrates filters as follows:
+
+```tsx
+'use client';
+
+export function DeliveryList() {
+  // Get filter state from URL
+  const { search, status, sortBy } = useDeliveryFilters();
+  
+  // Fetch deliveries with filters
+  const { data, isLoading, error } = useDeliveries({
+    search,
+    status,
+    sortBy,
+  });
+
+  return (
+    <div>
+      {/* Render filter UI */}
+      <DeliveryFilters />
+      
+      {/* Render delivery list with filtered data */}
+      {/* ... */}
+    </div>
+  );
+}
+```
+
+## Testing
+
+### Unit Tests Included
+
+1. **useDeliveryFilters.test.ts**
+   - Filter initialization
+   - Individual filter updates
+   - Multiple filter combinations
+   - Clear all filters
+   - Filter removal
+
+2. **DeliveryFilters.test.tsx**
+   - Component rendering
+   - Search input handling
+   - Status filter selection
+   - Sort filter selection
+   - Active filters display
+   - Clear filters functionality
+
+3. **deliveries.service.test.ts**
+   - API calls with filters
+   - Query parameter formatting
+   - Error handling
+   - Single and multiple filter combinations
+
+### Running Tests
+
+```bash
+# Run all tests
+npm test
+
+# Run specific test file
+npm test useDeliveryFilters.test.ts
+
+# Run tests in watch mode
+npm test --watch
+```
+
+## Browser Requirements
+
+- Requires modern browser support for:
+  - `URLSearchParams` API
+  - React 19+
+  - Next.js App Router
+
+## Performance Considerations
+
+1. **Search Debouncing**: Search input is only submitted on blur or Enter key, not on every keystroke
+2. **Query Key Caching**: React Query caches results based on filter combination, avoiding redundant API calls
+3. **URL State**: Filter state is persisted via URL, reducing client-side state management complexity
+4. **Shallow Routing**: Uses `scroll: false` option to prevent page scroll on filter updates
+
+## Error Handling
+
+- API errors are caught and displayed via the `useDeliveries` hook's error state
+- User can retry by clearing filters and searching again
+- Empty results display a helpful message suggesting filter adjustment
+
+## Future Enhancements
+
+- Add pagination support
+- Add advanced search with multiple fields
+- Add date range filtering
+- Add real-time filter suggestions
+- Add saved filter presets
+- Add export filtered results to CSV
+
+## Accessibility Features
+
+- All form inputs have associated labels
+- Clear visual feedback for active filters
+- Keyboard navigation support
+- ARIA labels for icon buttons
+- Dark mode support with proper contrast ratios
+
+## Browser Compatibility
+
+- Chrome/Edge: Latest 2 versions
+- Firefox: Latest 2 versions
+- Safari: Latest 2 versions
+- Mobile browsers: iOS Safari, Chrome Mobile
+
+## Notes
+
+- The implementation maintains backward compatibility with existing code
+- All state changes are URL-driven, enabling bookmarkable search results
+- The architecture is extensible for additional filters in the future
+- No breaking changes to existing DeliveryList functionality

+### DeliveryList Component Updates
+- Filter controls integrated above delivery list
+- Enhanced status badge colors (green for delivered, blue for in-transit, red for cancelled)
+- Timestamp display on each delivery
+- Amount display per delivery
+- Improved empty state message
+- Better responsive layout
+
+## 🚀 Integration Steps for Backend Team
+
+The backend API `/api/deliveries` endpoint should support the following:
+
+```javascript
+// Example Node.js/Express implementation
+app.get('/api/deliveries', async (req, res) => {
+  const { search, status, sortBy } = req.query;
+  
+  let query = Delivery.find();
+  
+  // Apply search filter
+  if (search) {
+    query = query.where('trackingNumber').regex(new RegExp(search, 'i'));
+  }
+  
+  // Apply status filter
+  if (status) {
+    query = query.where('status').equals(status);
+  }
+  
+  // Apply sorting
+  if (sortBy === 'date-desc') {
+    query = query.sort({ createdAt: -1 });
+  } else if (sortBy === 'date-asc') {
+    query = query.sort({ createdAt: 1 });
+  }
+  
+  const deliveries = await query.exec();
+  res.json(deliveries);
+});
+```
+

+## 🎓 Learning Resources
+
+### Concepts Used
+
+1. **URL State Management** - Persisting state via URL query parameters
+2. **Component → Hook → Service Pattern** - Layered architecture
+3. **React Query Integration** - Caching and auto-refetch
+4. **TypeScript** - Type safety
+5. **Next.js App Router** - `useSearchParams` and `useRouter`
+6. **Test-Driven Development** - Comprehensive test coverage
+
+### External References
+
+- [Next.js useSearchParams](https://nextjs.org/docs/app/api-reference/functions/use-search-params)
+- [React Query Documentation](https://tanstack.com/query/latest)
+- [URLSearchParams API](https://developer.mozilla.org/en-US/docs/Web/API/URLSearchParams)
+
+---
+
+## 📞 Support & Troubleshooting
+
+### Common Questions
+
+**Q: How do filters persist?**
+A: Filter state is encoded in URL query parameters. Page refresh reads these parameters and restores the filter state.
+
+**Q: How do I add a new filter?**
+A: Add it to `DeliveryFilterParams` in `types/filters.ts`, then update the service, hooks, and component.
+
+**Q: Can I use this in a server component?**
+A: No, hooks require client components. Use `'use client'` directive.
+
+**Q: Does it work offline?**
+A: Filters are stored in URL, but API calls require network connection.
+
+### Troubleshooting
+
+| Issue | Solution |
+|-------|----------|
+| Filters not persisting | Ensure page has `'use client'` directive |
+| No data showing | Verify backend API is working |
+| Filters not updating | Check hook is called correctly |
+| Type errors | Ensure filters match `DeliveryFilterParams` |

+# Quick Start Guide - Delivery Filters
+
+## 🚀 Quick Overview
+
+This feature adds search, filter, and sort controls to the delivery list with URL-based state persistence.
+
+## 📝 Basic Usage
+
+### Using the DeliveryList Component
+
+The `DeliveryList` component now automatically includes filters:
+
+```tsx
+import { DeliveryList } from '@/components/DeliveryList';
+
+export default function Page() {
+  return <DeliveryList />;
+}
+```
+
+That's it! The filters are built-in.
+
+## 🔧 Using Individual Hooks
+
+### Get Filter State
+```tsx
+'use client';
+
+import { useDeliveryFilters } from '@/features/deliveries/hooks';
+
+export function MyComponent() {
+  const { search, status, sortBy, hasActiveFilters } = useDeliveryFilters();
+  
+  console.log('Current filters:', { search, status, sortBy });
+  console.log('Has active filters:', hasActiveFilters);
+  
+  return <div>{/* ... */}</div>;
+}
+```
+
+### Update Filters
+```tsx
+'use client';
+
+import { useDeliveryFilters } from '@/features/deliveries/hooks';
+
+export function MyComponent() {
+  const { updateFilters, clearFilters } = useDeliveryFilters();
+  
+  return (
+    <div>
+      <button onClick={() => updateFilters({ search: 'TRK12345' })}>
+        Search
+      </button>
+      
+      <button onClick={() => updateFilters({ status: 'DELIVERED' })}>
+        Show Delivered
+      </button>
+      
+      <button onClick={() => updateFilters({ sortBy: 'date-desc' })}>
+        Sort Newest
+      </button>
+      
+      <button onClick={clearFilters}>
+        Clear All
+      </button>
+    </div>
+  );
+}
+```
+
+### Fetch Filtered Deliveries
+```tsx
+'use client';
+
+import { useDeliveries } from '@/hooks/useDeliveries';
+import { useDeliveryFilters } from '@/features/deliveries/hooks';
+
+export function DeliveryList() {
+  const { search, status, sortBy } = useDeliveryFilters();
+  const { data, isLoading, error } = useDeliveries({
+    search,
+    status,
+    sortBy,
+  });
+  
+  if (isLoading) return <div>Loading...</div>;
+  if (error) return <div>Error: {error.message}</div>;
+  
+  return (
+    <ul>
+      {data?.map(delivery => (
+        <li key={delivery.id}>{delivery.trackingNumber}</li>
+      ))}
+    </ul>
+  );
+}
+```
+
+## 📚 Filter Types
+
+```typescript
+interface DeliveryFilterParams {
+  search?: string;           // e.g., "TRK12345"
+  status?: string;          // "PENDING" | "ACCEPTED" | "IN_TRANSIT" | "DELIVERED" | "CANCELLED"
+  sortBy?: 'date-asc' | 'date-desc'; // Sort by date
+}
+```
+
+## 🌐 URL Query Parameters
+
+| Parameter | Example | Description |
+|-----------|---------|-------------|
+| search | `?search=TRK12345` | Search by tracking ID |
+| status | `?status=DELIVERED` | Filter by status |
+| sortBy | `?sortBy=date-desc` | Sort by date |
+
+### URL Examples
+
+```
+/deliveries                           # No filters
+/deliveries?search=TRK12345          # Search only
+/deliveries?status=DELIVERED         # Status only
+/deliveries?sortBy=date-desc         # Sort only
+/deliveries?search=TRK&status=DELIVERED&sortBy=date-desc # All combined
+```
+
+## 📋 Available Filter Values
+
+### Status Values
+- `PENDING` - Awaiting driver acceptance
+- `ACCEPTED` - Driver accepted delivery
+- `IN_TRANSIT` - Package in transit
+- `DELIVERED` - Package delivered
+- `CANCELLED` - Delivery cancelled
+
+### Sort Values
+- `date-asc` - Oldest first
+- `date-desc` - Newest first
+
+## ✨ Features
+
+### ✅ Search
+- Search by Tracking ID
+- Debounced on blur/Enter key
+- Clear button to reset
+
+### ✅ Filter

+- Page refresh maintains state
+- Shareable URLs with filter state
+
+### ✅ UI

+
+## 🧪 Testing
+
+### Run Tests
+```bash
+npm test -- --testPathPattern="useDeliveryFilters|DeliveryFilters|deliveries.service"
+```
+
+### Manual Testing
+1. Go to `/deliveries`
+2. Search for a tracking ID
+3. Change status filter
+4. Change sort order
+5. Refresh page - filters should persist
+6. Check URL - should include query parameters
+
+## 🔌 Backend Integration
+
+Your backend API needs to handle:
+
+```
+GET /api/deliveries?search={search}&status={status}&sortBy={sortBy}
+```
+
+Example implementation (Node.js/Express):
+
+```javascript
+app.get('/api/deliveries', async (req, res) => {
+  const { search, status, sortBy } = req.query;
+  
+  let query = Delivery.find();
+  
+  if (search) {
+    query = query.where('trackingNumber').regex(new RegExp(search, 'i'));
+  }
+  
+  if (status) {
+    query = query.where('status').equals(status);
+  }
+  
+  if (sortBy === 'date-desc') {
+    query = query.sort({ createdAt: -1 });
+  } else if (sortBy === 'date-asc') {
+    query = query.sort({ createdAt: 1 });
+  }
+  
+  const deliveries = await query.exec();
+  res.json(deliveries);
+});
+```
+
+## 📁 File Locations
+
+| Component | Location |
+|-----------|----------|
+| Filter Component | `features/deliveries/components/DeliveryFilters.tsx` |
+| Filter Hook | `features/deliveries/hooks/useDeliveryFilters.ts` |
+| Deliveries Hook | `hooks/useDeliveries.ts` |
+| Deliveries Service | `services/deliveries.service.ts` |
+| Filter Types | `types/filters.ts` |
+| Delivery List | `components/DeliveryList.tsx` |
+
+## 🎓 Common Patterns
+
+### Pattern 1: Filter from Another Component
+```tsx
+import { useDeliveryFilters } from '@/features/deliveries/hooks';
+
+export function SearchBar() {
+  const { updateFilters } = useDeliveryFilters();
+  
+  const handleSearch = (trackingId: string) => {
+    updateFilters({ search: trackingId });
+  };
+  
+  return <input onChange={(e) => handleSearch(e.target.value)} />;
+}
+```
+
+### Pattern 2: Status Selector
+```tsx
+export function StatusSelector() {
+  const { updateFilters } = useDeliveryFilters();
+  
+  return (
+    <select onChange={(e) => updateFilters({ status: e.target.value })}>
+      <option value="">All Statuses</option>
+      <option value="PENDING">Pending</option>
+      <option value="DELIVERED">Delivered</option>
+    </select>
+  );
+}
+```
+
+### Pattern 3: Conditional Rendering Based on Filters
+```tsx
+export function DeliveryStats() {
+  const { hasActiveFilters, clearFilters } = useDeliveryFilters();
+  
+  return (
+    <div>
+      {hasActiveFilters && (
+        <button onClick={clearFilters}>Clear Filters</button>
+      )}
+    </div>
+  );
+}
+```
+
+## ⚠️ Important Notes
+
+1. **URL State Only**: All state is managed via URL query parameters
+2. **Server Components**: Use `'use client'` directive when using hooks
+3. **No Mock Data**: All data comes from backend API
+4. **Automatic Sync**: URL changes automatically trigger data refresh
+5. **Backward Compatible**: Works with existing code
+
+## 🐛 Troubleshooting
+
+### Filters not persisting on refresh
+- Check if page is using `'use client'` directive
+- Verify URL has query parameters
+
+### No data showing
+- Check backend API is returning correct response
+- Verify filter values match API expectations
+- Check browser console for errors
+
+### Filters not updating
+- Verify hook is called inside a client component
+- Check that `updateFilters` is being called correctly
+- Verify API endpoint is working

+
+## 📊 State Management Flow
+
+### URL State → Component State
+
+```
+URL: /deliveries?search=TRK&status=DELIVERED&sortBy=date-desc
+
+↓
+
+useSearchParams() reads URL
+↓
+parseQuery params
+↓
+{
+  search: 'TRK',
+  status: 'DELIVERED',
+  sortBy: 'date-desc',
+  hasActiveFilters: true
+}
+
+↓
+
+DeliveryFilters component receives state

+
+DeliveryList receives state
+↓
+Passes to useDeliveries hook
+↓
+API called with filters
+↓
+Data rendered with filter applied
+```
+
+---
+
+## 🎯 Interaction Patterns
+
+### Pattern 1: Single Filter Application
+```
+User selects Status → URL updates → Data refetches → List updates
+```
+
+### Pattern 2: Multi-Filter Application
+```
+User applies search
+User changes status
+User selects sort
+(All while others remain active)
+→ URL has ?search=X&status=Y&sortBy=Z
+→ Data refetches with all filters
+→ List updates with fully filtered data
+```
+
+### Pattern 3: Filter Modification
+```
+Current: ?search=TRK&status=DELIVERED
+User changes status to PENDING
+→ URL becomes: ?search=TRK&status=PENDING
+→ Old data cleared
+→ New filtered data fetched
+→ List updates
+```
+
+### Pattern 4: Filter Clearing
+```
+Current: ?search=TRK&status=DELIVERED&sortBy=date-desc
+User clicks "Clear Filters"
+→ URL becomes: /deliveries
+→ All filter values reset to undefined
+→ useDeliveries receives empty object
+→ API called without filters
+→ All deliveries returned
+→ List updates to show everything
+```
+
+---
+
+## 🧪 Testing Scenarios
+
+### Test Scenario 1: Search Filter
+```

+→ User shares URL with colleague
+→ Colleague opens URL
+→ Same filters are applied automatically
+```
+
+### ✅ Feature: Active Filters Display
+```
+User applies: search, status, sort
+→ Each filter appears as visual badge
+→ Shows filter name and value
+→ User can see at a glance what's filtered

-# Global Layout & Responsive Sidebar - Implementation Summary
-
-## Overview
-
-Implemented a global application shell (`AppLayout`) with a responsive sidebar system that adapts to both desktop and mobile viewports. The implementation follows the strict Component → Hook → Service layered architecture pattern.
-
-## Implementation Details
-
-### Architecture: Component → Hook → Service Pattern ✓
-
-#### 1. **Service Layer** (`services/layoutService.ts`)
-
-- **Responsibility**: Manages all layout-related API communication and configuration
-- **Key Features**:
-  - Fetches layout configuration from backend API
-  - Retrieves navigation items based on user context
-  - Manages user layout preferences (sidebar collapsed state, theme)
-  - Provides fallback default configuration when API fails
-  - Type-safe interfaces for all data structures
-- **Key Methods**:
-  - `getLayoutConfig()`: Fetches branding and theme config
-  - `getNavigationItems()`: Retrieves personalized nav items
-  - `getUserLayoutPreferences()`: Gets user-specific preferences
-  - `saveUserLayoutPreferences()`: Persists user preferences
-
-#### 2. **Custom Hook** (`hooks/useAppLayout.ts`)
-
-- **Responsibility**: Manages React component state and lifecycle
-- **Key Features**:
-  - Detects mobile vs desktop (breakpoint: lg = 1024px)
-  - Manages sidebar visibility state
-  - Manages sidebar collapse state (desktop)
-  - Handles window resize events
-  - Provides method to filter nav items by role
-  - Automatically initializes on mount
-- **Exposed API**:
-  - `state`: Layout state (isLoading, error, isMobile, sidebarOpen, etc.)
-  - `toggleSidebar()`: Toggle sidebar visibility on mobile
-  - `closeSidebar()`: Close sidebar
-  - `openSidebar()`: Open sidebar
-  - `toggleSidebarCollapse()`: Toggle collapse state on desktop
-  - `getVisibleNavItems()`: Get filtered navigation items
-
-#### 3. **UI Component** (`components/layout/AppLayout.tsx`)
-
-- **Responsibility**: Renders the application shell with responsive behavior
-- **Structure**:
-  - `DesktopSidebar`: Fixed left sidebar (hidden on mobile)
-  - `MobileBottomSheet`: Bottom-sheet menu (mobile only)
-  - `NavLink`: Reusable navigation link component
-  - Main layout wrapper with responsive margins
-- **Key Features**:
-  - Responsive breakpoint: lg (1024px)
-  - Mobile first approach with progressive enhancement
-  - Dark mode support throughout
-  - Loading state with spinner
-  - Smooth transitions and animations
-  - Accessibility features (ARIA labels, semantic HTML)
-
-### Files Created
-
-| File                              | Purpose                  | Lines |
-| --------------------------------- | ------------------------ | ----- |
-| `services/layoutService.ts`       | API integration & config | 186   |
-| `hooks/useAppLayout.ts`           | State management & logic | 142   |
-| `components/layout/AppLayout.tsx` | UI rendering             | 268   |
-
-## Responsive Design
-
-### Desktop (1024px+)
-
-- **Sidebar**: Fixed left sidebar, 256px wide (or 80px when collapsed)
-- **Layout**: Main content shifts right based on sidebar state
-- **Interaction**: Click toggle button to collapse/expand sidebar
-- **Features**:
-  - Collapsible sidebar with smooth transition
-  - Full navigation items visible
-  - Descriptions shown under nav labels
-
-### Mobile (< 1024px, tested at 375px)
-
-- **Header**: Sticky top header with hamburger menu icon
-- **Navigation**: Bottom-sheet drawer (slides up from bottom)
-- **Layout**: Full width main content
-- **Interactions**:
-  - Tap hamburger to open bottom-sheet
-  - Tap X or backdrop to close
-  - Auto-closes when navigating to a link
-- **Features**:
-  - Non-blocking bottom-sheet (draggable area at top)
-  - Smooth slide-in animation
-  - Dark overlay backdrop
-  - Full navigation items visible in sheet
-
-## Component Usage
-
-```tsx
-import AppLayout from '@/components/layout/AppLayout';
-
-export default function RootLayout({ children }) {
-  return (
-    <html>
-      <body>
-        <AppLayout>{children}</AppLayout>
-      </body>
-    </html>
-  );
-}
-```
-
-## Data Flow
-
-```
-Backend API
-    ↓
-layoutService (fetch & format)
-    ↓
-useAppLayout Hook (state management)
-    ↓
-AppLayout Component (render)
-    ↓
-NavLink Components (interactive)
-```
-
-## API Integration
-
-### Expected Backend Endpoints
-
-1. **GET `/api/layout/config`**
-
-   ```json
-   {
-     "success": true,
-     "data": {
-       "branding": {
-         "appName": "SwiftChain",
-         "logo": "/logo.svg",
-         "logoDark": "/logo-dark.svg"
-       },
-       "navigation": [...],
-       "theme": {
-         "primaryColor": "#3b82f6",
-         "sidebarCollapsible": true
-       }
-     }
-   }
-   ```
-
-2. **GET `/api/layout/navigation`**
-
-   ```json
-   {
-     "success": true,
-     "data": [
-       {
-         "id": "dashboard",
-         "label": "Dashboard",
-         "href": "/dashboard",
-         "icon": "📊",
-         "description": "Overview and stats",
-         "roles": ["customer", "driver", "admin"]
-       },
-       ...
-     ]
-   }
-   ```
-
-3. **GET `/api/layout/preferences`**
-
-   ```json
-   {
-     "success": true,
-     "data": {
-       "sidebarCollapsed": false,
-       "theme": "light",
-       "sidebarWidth": 256
-     }
-   }
-   ```
-
-4. **PATCH `/api/layout/preferences`**
-   - Request: `{ "sidebarCollapsed": boolean, "theme": "light" | "dark" }`
-   - Response: Same as GET
-
-### Fallback Strategy
-
-- If API calls fail, service returns default configuration
-- Navigation items still functional with default items
-- User preferences default to: sidebar expanded, light theme, 256px width
-- No breaking UI changes due to API failures
-
-## Responsive Breakpoints
-
-| Breakpoint     | Width          | Sidebar       |
-| -------------- | -------------- | ------------- |
-| Mobile (xs-sm) | < 1024px       | Bottom-sheet  |
-| Tablet (md)    | 768px - 1023px | Bottom-sheet  |
-| Desktop (lg)   | ≥ 1024px       | Fixed sidebar |
-
-## Styling & Theme
-
-### Color Scheme
-
-- **Primary**: Uses Tailwind `primary` color (#3b82f6)
-- **Light Mode**: Slate-50 background, white sidebar
-- **Dark Mode**: Slate-950 background, slate-900 sidebar
-- **Hover States**: Slate-100/800 backgrounds
-- **Borders**: Slate-200/800 colors
-
-### Animations
-
-- **Sidebar Toggle**: 300ms ease transitions
-- **Bottom Sheet**: 300ms ease translate animations
-- **Nav Items**: 200ms ease color/background transitions
-- **Loading Spinner**: Continuous rotation animation
-
-### Accessibility
-
-- Semantic HTML (header, nav, main, aside)
-- ARIA labels on all interactive elements
-- Proper heading hierarchy
-- Keyboard navigation support
-- Color contrast compliance (WCAG AA)
-- Focus management
-

-# Delivery List Filter & Sort Implementation Guide
-
-## Overview
-This document outlines the implementation of delivery list filter and sort controls for the SwiftChain frontend application. The implementation follows a strict **Component → Hook → Service** layered architecture and maintains filter state through URL query parameters for persistent state across page refreshes.
-

-```
-
-## Components & Hooks
-
-### 1. DeliveryFilters Component (`features/deliveries/components/DeliveryFilters.tsx`)
-
-**Responsibility**: Renders the UI for filtering and sorting deliveries.
-
-**Features**:
-- Search by Tracking ID (with debounce on blur/Enter)
-- Filter by Status dropdown
-- Sort by Date dropdown
-- Display active filters with visual badges
-- Clear all filters button
-
-**Props**: None (uses `useDeliveryFilters` hook internally)
-
-**Example Usage**:
-```tsx
-import { DeliveryFilters } from '@/features/deliveries/components/DeliveryFilters';
-
-export function DeliveryPage() {
-  return (
-    <div>
-      <DeliveryFilters />
-      {/* Rest of component */}
-    </div>
-  );
-}
-```
-
-### 2. useDeliveryFilters Hook (`features/deliveries/hooks/useDeliveryFilters.ts`)
-
-**Responsibility**: Manages filter state through URL query parameters and provides methods to update filters.
-
-**Features**:
-- Reads filter state from URL query parameters
-- Provides `updateFilters` method to update one or more filters
-- Provides `clearFilters` method to reset all filters
-- Automatically syncs state with URL for persistence
-- Returns `hasActiveFilters` flag for UI feedback
-
-**Returns**:
-```typescript
-{
-  search?: string;           // Search query
-  status?: string;           // Delivery status filter
-  sortBy?: 'date-asc' | 'date-desc'; // Sort order
-  hasActiveFilters: boolean; // Whether any filters are active
-  updateFilters: (params: Partial<DeliveryFilterParams>) => void;
-  clearFilters: () => void;
-}
-```
-
-**Example Usage**:
-```tsx
-const { search, status, sortBy, updateFilters, clearFilters, hasActiveFilters } = useDeliveryFilters();
-
-// Update individual filter
-updateFilters({ search: 'TRK12345' });
-
-// Update multiple filters
-updateFilters({ status: 'DELIVERED', sortBy: 'date-desc' });
-
-// Clear all filters
-clearFilters();
-```
-
-### 3. useDeliveries Hook (`hooks/useDeliveries.ts`)
-
-**Responsibility**: Fetches deliveries from the backend with optional filter parameters.
-
-**Features**:
-- Integrates with React Query for caching and state management
-- Accepts optional filter parameters
-- Manages loading and error states
-- Automatic query key invalidation when filters change
-
-**Returns**:
-```typescript
-{
-  data?: Delivery[];
-  isLoading: boolean;
-  error?: Error;
-}
-```
-
-**Example Usage**:
-```tsx
-const { search, status, sortBy } = useDeliveryFilters();
-const { data, isLoading, error } = useDeliveries({
-  search,
-  status,
-  sortBy,
-});
-```
-
-## Service Integration
-
-### deliveriesService (`services/deliveries.service.ts`)
-
-**Responsibility**: Handles API communication with the backend.
-
-**Methods**:
-
-#### `getDeliveries(filters?: DeliveryFilterParams): Promise<Delivery[]>`
-Fetches deliveries from the backend with optional filters.
-
-**Parameters**:
-```typescript
-{
-  search?: string;           // Search by tracking number
-  status?: string;           // Filter by status
-  sortBy?: 'date-asc' | 'date-desc'; // Sort order
-}
-```
-
-**Example**:
-```typescript
-// Fetch all deliveries
-await deliveriesService.getDeliveries();
-
-// Fetch with filters
-await deliveriesService.getDeliveries({
-  search: 'TRK12345',
-  status: 'IN_TRANSIT',
-  sortBy: 'date-desc'
-});
-```
-
-#### `getDeliveryById(id: string): Promise<Delivery>`
-Fetches a specific delivery by ID.
-
-## Type Definitions
-
-### FilterParams Type (`types/filters.ts`)
-
-```typescript
-interface DeliveryFilterParams {
-  search?: string;
-  status?: string;
-  sortBy?: 'date-asc' | 'date-desc';
-}
-
-interface FilterState extends DeliveryFilterParams {
-  hasActiveFilters: boolean;
-}
-```
-
-## URL Query Parameters
-
-Filter state is persisted through URL query parameters. Here are the supported parameters:
-
-| Parameter | Type | Example |
-|-----------|------|---------|
-| `search` | string | `?search=TRK12345` |
-| `status` | string | `?status=DELIVERED` |
-| `sortBy` | string | `?sortBy=date-desc` |
-
-**Combined Example**:
-```
-/deliveries?search=TRK12345&status=IN_TRANSIT&sortBy=date-desc
-```
-
-## API Endpoint Contract
-
-The backend API should support the following endpoint:
-
-```
-GET /api/deliveries?search={search}&status={status}&sortBy={sortBy}
-```
-
-### Request Query Parameters
-- `search` (optional): Search deliveries by tracking number
-- `status` (optional): Filter by delivery status (PENDING, ACCEPTED, IN_TRANSIT, DELIVERED, CANCELLED)
-- `sortBy` (optional): Sort deliveries (date-asc, date-desc)
-
-### Response
-```json
-[
-  {
-    "id": "uuid",
-    "trackingNumber": "TRK12345",
-    "senderId": "uuid",
-    "driverId": "uuid",
-    "status": "IN_TRANSIT",

-- `CANCELLED`: Delivery was cancelled
-
-## Data Flow Diagram
-
-```
-User interacts with DeliveryFilters component
-        ↓
-updateFilters() called with new filter values
-        ↓
-useDeliveryFilters updates URL query parameters
-        ↓
-URL changes, triggering component re-render
-        ↓

-```
-
-## Integration with DeliveryList
-
-The `DeliveryList` component integrates filters as follows:
-
-```tsx
-'use client';
-
-export function DeliveryList() {
-  // Get filter state from URL
-  const { search, status, sortBy } = useDeliveryFilters();
-  
-  // Fetch deliveries with filters
-  const { data, isLoading, error } = useDeliveries({
-    search,
-    status,
-    sortBy,
-  });
-
-  return (
-    <div>
-      {/* Render filter UI */}
-      <DeliveryFilters />
-      
-      {/* Render delivery list with filtered data */}
-      {/* ... */}
-    </div>
-  );
-}
-```
-
-## Testing
-
-### Unit Tests Included
-
-1. **useDeliveryFilters.test.ts**
-   - Filter initialization
-   - Individual filter updates
-   - Multiple filter combinations
-   - Clear all filters
-   - Filter removal
-
-2. **DeliveryFilters.test.tsx**
-   - Component rendering
-   - Search input handling
-   - Status filter selection
-   - Sort filter selection
-   - Active filters display
-   - Clear filters functionality
-
-3. **deliveries.service.test.ts**
-   - API calls with filters
-   - Query parameter formatting
-   - Error handling
-   - Single and multiple filter combinations
-
-### Running Tests
-
-```bash
-# Run all tests
-npm test
-
-# Run specific test file
-npm test useDeliveryFilters.test.ts
-
-# Run tests in watch mode
-npm test --watch
-```
-
-## Browser Requirements
-
-- Requires modern browser support for:
-  - `URLSearchParams` API
-  - React 19+
-  - Next.js App Router
-
-## Performance Considerations
-
-1. **Search Debouncing**: Search input is only submitted on blur or Enter key, not on every keystroke
-2. **Query Key Caching**: React Query caches results based on filter combination, avoiding redundant API calls
-3. **URL State**: Filter state is persisted via URL, reducing client-side state management complexity
-4. **Shallow Routing**: Uses `scroll: false` option to prevent page scroll on filter updates
-
-## Error Handling
-
-- API errors are caught and displayed via the `useDeliveries` hook's error state
-- User can retry by clearing filters and searching again
-- Empty results display a helpful message suggesting filter adjustment
-
-## Future Enhancements
-
-- Add pagination support
-- Add advanced search with multiple fields
-- Add date range filtering
-- Add real-time filter suggestions
-- Add saved filter presets
-- Add export filtered results to CSV
-
-## Accessibility Features
-
-- All form inputs have associated labels
-- Clear visual feedback for active filters
-- Keyboard navigation support
-- ARIA labels for icon buttons
-- Dark mode support with proper contrast ratios
-
-## Browser Compatibility
-
-- Chrome/Edge: Latest 2 versions
-- Firefox: Latest 2 versions
-- Safari: Latest 2 versions
-- Mobile browsers: iOS Safari, Chrome Mobile
-
-## Notes
-
-- The implementation maintains backward compatibility with existing code
-- All state changes are URL-driven, enabling bookmarkable search results
-- The architecture is extensible for additional filters in the future
-- No breaking changes to existing DeliveryList functionality

-
-## 🚀 Integration Steps for Backend Team
-
-The backend API `/api/deliveries` endpoint should support the following:
-
-```javascript
-// Example Node.js/Express implementation
-app.get('/api/deliveries', async (req, res) => {
-  const { search, status, sortBy } = req.query;
-  
-  let query = Delivery.find();
-  
-  // Apply search filter
-  if (search) {
-    query = query.where('trackingNumber').regex(new RegExp(search, 'i'));
-  }
-  
-  // Apply status filter
-  if (status) {
-    query = query.where('status').equals(status);
-  }
-  
-  // Apply sorting
-  if (sortBy === 'date-desc') {
-    query = query.sort({ createdAt: -1 });
-  } else if (sortBy === 'date-asc') {
-    query = query.sort({ createdAt: 1 });
-  }
-  
-  const deliveries = await query.exec();
-  res.json(deliveries);
-});
-```

----
-
-## 📞 Support & Troubleshooting
-
-### Common Questions
-
-**Q: How do filters persist?**
-A: Filter state is encoded in URL query parameters. Page refresh reads these parameters and restores the filter state.
-
-**Q: How do I add a new filter?**
-A: Add it to `DeliveryFilterParams` in `types/filters.ts`, then update the service, hooks, and component.
-
-**Q: Can I use this in a server component?**
-A: No, hooks require client components. Use `'use client'` directive.
-
-**Q: Does it work offline?**
-A: Filters are stored in URL, but API calls require network connection.
-
-### Troubleshooting
-
-| Issue | Solution |
-|-------|----------|
-| Filters not persisting | Ensure page has `'use client'` directive |
-| No data showing | Verify backend API is working |
-| Filters not updating | Check hook is called correctly |
-| Type errors | Ensure filters match `DeliveryFilterParams` |

-```tsx
-'use client';
-
-import { useModal } from '@/hooks/useModal';
-
-export function MyComponent() {
-  const { open, close } = useModal();
-
-  const handleOpenModal = () => {
-    open({
-      id: 'my-modal',
-      title: 'Confirm Action',
-      content: 'Are you sure you want to proceed?',
-      size: 'md',
-      position: 'center',
-      closeable: true,
-      focusTrap: true,
-      onConfirm: async () => {
-        // Handle confirmation
-        console.log('Confirmed!');
-        close(); // Manually close after action
-      },
-      confirmLabel: 'Confirm',
-      cancelLabel: 'Cancel',
-    });
-  };
-
-  return <button onClick={handleOpenModal}>Open Modal</button>;
-}
-```
-
-### Loading Modal
-
-```tsx
-const { open } = useModal();
-
-open({
-  id: 'loading-modal',
-  title: 'Processing',
-  content: 'Please wait while we process your request...',
-  closeable: false,
-  isLoading: true,
-});
-
-// Later...
-close();
-```
-
-### Modal from Template
-
-```tsx

-
-await openFromTemplate('confirm-delete-modal');
-```
-
-### Nested Modals
-
-```tsx
-const { open, close } = useModal();
-
-// Open first modal
-open({
-  id: 'modal-1',
-  title: 'First Modal',
-  content: 'Click button to open nested modal',
-  onConfirm: () => {
-    // Open nested modal
-    open({
-      id: 'modal-2',
-      title: 'Second Modal',
-      content: 'This is nested!',
-    });
-  },
-});
-```
-
-## API Integration
-
-### Expected Backend Endpoints
-
-1. **GET `/api/modals/templates`**
-
-   ```json
-   {
-     "success": true,
-     "data": [
-       {
-         "id": "confirm-delete",
-         "name": "Confirm Delete",
-         "title": "Delete Item",
-         "content": "Are you sure you want to delete this item?",
-         "size": "md",
-         "position": "center",
-         "closeable": true,
-         "backdropBlur": true,
-         "focusTrap": true,
-         "confirmLabel": "Delete",
-         "cancelLabel": "Cancel"
-       }
-     ]
-   }
-   ```
-
-2. **GET `/api/modals/templates/{id}`**
-   - Returns single modal template
-
-3. **GET `/api/modals/config`**
-
-   ```json
-   {
-     "success": true,
-     "data": {
-       "defaultSize": "md",
-       "enableAnimations": true
-     }
-   }
-   ```
-
-4. **POST `/api/modals/{id}/action`**
-   - Request: `{ "action": "string", "data": any }`
-   - Response: Confirmation of action
-
-### Fallback Strategy
-
-- If API fails, modals still work with provided configuration
-- Default size: md
-- Default position: center
-- No template system but direct configuration still works
-
-## Accessibility Features

-# Quick Start Guide - Delivery Filters
-
-## 🚀 Quick Overview
-
-This feature adds search, filter, and sort controls to the delivery list with URL-based state persistence.
-
-## 📝 Basic Usage
-
-### Using the DeliveryList Component
-
-The `DeliveryList` component now automatically includes filters:
-
-```tsx
-import { DeliveryList } from '@/components/DeliveryList';
-
-export default function Page() {
-  return <DeliveryList />;
-}
-```
-
-That's it! The filters are built-in.
-
-## 🔧 Using Individual Hooks
-
-### Get Filter State
-```tsx
-'use client';
-
-import { useDeliveryFilters } from '@/features/deliveries/hooks';
-
-export function MyComponent() {
-  const { search, status, sortBy, hasActiveFilters } = useDeliveryFilters();
-  
-  console.log('Current filters:', { search, status, sortBy });
-  console.log('Has active filters:', hasActiveFilters);
-  
-  return <div>{/* ... */}</div>;
-}
-```
-
-### Update Filters
-```tsx
-'use client';
-
-import { useDeliveryFilters } from '@/features/deliveries/hooks';
-
-export function MyComponent() {
-  const { updateFilters, clearFilters } = useDeliveryFilters();
-  
-  return (
-    <div>
-      <button onClick={() => updateFilters({ search: 'TRK12345' })}>
-        Search
-      </button>
-      
-      <button onClick={() => updateFilters({ status: 'DELIVERED' })}>
-        Show Delivered
-      </button>
-      
-      <button onClick={() => updateFilters({ sortBy: 'date-desc' })}>
-        Sort Newest
-      </button>
-      
-      <button onClick={clearFilters}>
-        Clear All
-      </button>
-    </div>
-  );
-}
-```
-
-### Fetch Filtered Deliveries
-```tsx
-'use client';
-
-import { useDeliveries } from '@/hooks/useDeliveries';
-import { useDeliveryFilters } from '@/features/deliveries/hooks';
-
-export function DeliveryList() {
-  const { search, status, sortBy } = useDeliveryFilters();
-  const { data, isLoading, error } = useDeliveries({
-    search,
-    status,
-    sortBy,
-  });
-  
-  if (isLoading) return <div>Loading...</div>;
-  if (error) return <div>Error: {error.message}</div>;
-  
-  return (
-    <ul>
-      {data?.map(delivery => (
-        <li key={delivery.id}>{delivery.trackingNumber}</li>
-      ))}
-    </ul>
-  );
-}
-```
-
-## 📚 Filter Types
-
-```typescript
-interface DeliveryFilterParams {
-  search?: string;           // e.g., "TRK12345"
-  status?: string;          // "PENDING" | "ACCEPTED" | "IN_TRANSIT" | "DELIVERED" | "CANCELLED"
-  sortBy?: 'date-asc' | 'date-desc'; // Sort by date
-}
-```
-
-## 🌐 URL Query Parameters
-
-| Parameter | Example | Description |
-|-----------|---------|-------------|
-| search | `?search=TRK12345` | Search by tracking ID |
-| status | `?status=DELIVERED` | Filter by status |
-| sortBy | `?sortBy=date-desc` | Sort by date |
-
-### URL Examples
-
-```
-/deliveries                           # No filters
-/deliveries?search=TRK12345          # Search only
-/deliveries?status=DELIVERED         # Status only
-/deliveries?sortBy=date-desc         # Sort only
-/deliveries?search=TRK&status=DELIVERED&sortBy=date-desc # All combined
-```
-
-## 📋 Available Filter Values
-
-### Status Values
-- `PENDING` - Awaiting driver acceptance
-- `ACCEPTED` - Driver accepted delivery
-- `IN_TRANSIT` - Package in transit
-- `DELIVERED` - Package delivered
-- `CANCELLED` - Delivery cancelled
-
-### Sort Values
-- `date-asc` - Oldest first
-- `date-desc` - Newest first
-
-## ✨ Features
-
-### ✅ Search
-- Search by Tracking ID
-- Debounced on blur/Enter key
-- Clear button to reset
-
-### ✅ Filter
-- Dropdown with all 5 status options
-- Select multiple times (updates previous selection)
-- Combine with other filters
-
-### ✅ Sort
-- Sort by date ascending/descending
-- Combine with search and filter
-
-### ✅ Persistence
-- All filters persist in URL
-- Page refresh maintains state
-- Shareable URLs with filter state
-
-### ✅ UI
-- Visual badges for active filters
-- Clear all button
-- Dark mode support
-- Mobile responsive
-- Full keyboard navigation
-
-## 🧪 Testing
-
-### Run Tests
-```bash
-npm test -- --testPathPattern="useDeliveryFilters|DeliveryFilters|deliveries.service"
-```
-
-### Manual Testing
-1. Go to `/deliveries`
-2. Search for a tracking ID
-3. Change status filter
-4. Change sort order
-5. Refresh page - filters should persist
-6. Check URL - should include query parameters
-
-## 🔌 Backend Integration
-
-Your backend API needs to handle:
-
-```
-GET /api/deliveries?search={search}&status={status}&sortBy={sortBy}
-```
-
-Example implementation (Node.js/Express):
-
-```javascript
-app.get('/api/deliveries', async (req, res) => {
-  const { search, status, sortBy } = req.query;
-  
-  let query = Delivery.find();
-  
-  if (search) {
-    query = query.where('trackingNumber').regex(new RegExp(search, 'i'));
-  }
-  
-  if (status) {
-    query = query.where('status').equals(status);
-  }
-  
-  if (sortBy === 'date-desc') {
-    query = query.sort({ createdAt: -1 });
-  } else if (sortBy === 'date-asc') {
-    query = query.sort({ createdAt: 1 });
-  }
-  
-  const deliveries = await query.exec();
-  res.json(deliveries);
-});
-```
-
-## 📁 File Locations
-
-| Component | Location |
-|-----------|----------|
-| Filter Component | `features/deliveries/components/DeliveryFilters.tsx` |
-| Filter Hook | `features/deliveries/hooks/useDeliveryFilters.ts` |
-| Deliveries Hook | `hooks/useDeliveries.ts` |
-| Deliveries Service | `services/deliveries.service.ts` |
-| Filter Types | `types/filters.ts` |
-| Delivery List | `components/DeliveryList.tsx` |
-
-## 🎓 Common Patterns
-
-### Pattern 1: Filter from Another Component
-```tsx
-import { useDeliveryFilters } from '@/features/deliveries/hooks';
-
-export function SearchBar() {
-  const { updateFilters } = useDeliveryFilters();
-  
-  const handleSearch = (trackingId: string) => {
-    updateFilters({ search: trackingId });
-  };
-  
-  return <input onChange={(e) => handleSearch(e.target.value)} />;
-}
-```
-
-### Pattern 2: Status Selector
-```tsx
-export function StatusSelector() {
-  const { updateFilters } = useDeliveryFilters();
-  
-  return (
-    <select onChange={(e) => updateFilters({ status: e.target.value })}>
-      <option value="">All Statuses</option>
-      <option value="PENDING">Pending</option>
-      <option value="DELIVERED">Delivered</option>
-    </select>
-  );
-}
-```
-
-### Pattern 3: Conditional Rendering Based on Filters
-```tsx
-export function DeliveryStats() {
-  const { hasActiveFilters, clearFilters } = useDeliveryFilters();
-  
-  return (
-    <div>
-      {hasActiveFilters && (
-        <button onClick={clearFilters}>Clear Filters</button>
-      )}
-    </div>
-  );
-}
-```
-
-## ⚠️ Important Notes
-
-1. **URL State Only**: All state is managed via URL query parameters
-2. **Server Components**: Use `'use client'` directive when using hooks
-3. **No Mock Data**: All data comes from backend API
-4. **Automatic Sync**: URL changes automatically trigger data refresh
-5. **Backward Compatible**: Works with existing code
-
-## 🐛 Troubleshooting
-
-### Filters not persisting on refresh
-- Check if page is using `'use client'` directive
-- Verify URL has query parameters
-
-### No data showing
-- Check backend API is returning correct response
-- Verify filter values match API expectations
-- Check browser console for errors
-
-### Filters not updating
-- Verify hook is called inside a client component
-- Check that `updateFilters` is being called correctly
-- Verify API endpoint is working

-# SwiftChain - Frontend
-
-**SwiftChain** is a Blockchain-Powered Logistics & Escrow Delivery Platform built on the Stellar blockchain. It connects customers, independent drivers, and logistics operators in a decentralized network, ensuring secure and transparent deliveries through smart contract escrow payments.
-
-This repository (`SwiftChain-Frontend`) contains the frontend application built with **Next.js**, **TypeScript**, and **TailwindCSS**.
-
----
-
-## 🚀 Project Overview
-
-### Core Problem
-
-Traditional logistics systems suffer from:
-
-- Lack of trust between senders and independent drivers.
-- High fees and slow payments for drivers.
-- Limited access for small courier businesses and unbanked drivers.
-- Inefficient cross-border settlement.
-
-### Solution
-
-SwiftChain introduces a decentralized logistics network where:
-
-- **Smart Contracts** hold funds in escrow until delivery is verified.
-- **Stellar Blockchain** facilitates fast, low-cost payments.
-- **Independent Drivers** and small businesses can compete on a level playing field.
-
-### How It Works
-
-1.  **Sender** creates a delivery request and locks payment in an escrow smart contract.
-2.  **Driver** accepts the delivery job.
-3.  **Package** is transported to the destination.
-4.  **Recipient** confirms receipt (or driver provides proof).
-5.  **Escrow** automatically releases payment to the driver.
-
-### Financial Inclusion Benefits
-
-- Empowers independent drivers and small courier businesses.
-- Provides access to global logistics markets for underserved regions (e.g., African markets).
-- Enables cross-border merchants to settle payments instantly.
-
----
-
-## 🎯 Target Market
-
-- **African Logistics Markets**: Connecting informal transport sectors.
-- **Cross-Border Merchants**: Facilitating trade between regions.
-- **SME Businesses**: Affordable and reliable delivery options.
-- **E-commerce Sellers**: Integrated delivery solutions.
-- **Independent Delivery Drivers**: Gig economy opportunities with fair pay.
-
----
-
-## 💰 Revenue Model
-
-The platform generates revenue through:
-
-- **Delivery Commission Fee**: Small percentage of each successful delivery.
-- **Escrow Service Fee**: Fee for securing funds in smart contracts.
-- **Enterprise Logistics Integration**: Premium API access for large logistics companies.
-- **Cross-Border Settlement Fees**: Currency conversion and cross-border transaction fees.
-- **Premium Fleet Management Tools**: Subscription-based tools for fleet operators.
-
----
-
-## 🏗️ Platform Architecture
-
-The SwiftChain platform consists of three main repositories:
-
-1.  **SwiftChain-Frontend** (This Repo): Next.js + TypeScript + TailwindCSS. Handles UI, user interaction, and client-side logic.
-2.  **SwiftChain-Backend**: Express.js + Node.js + TypeScript + MongoDB. Manages off-chain data, user accounts, and API orchestration.

-}
-```
-
----
-
-## Environment Setup
-
-### Required Environment Variables
-
-Create `.env.local`:
-
-```
-NEXT_PUBLIC_API_URL=http://localhost:3001
-```
-
-Or for production:
-
-```
-NEXT_PUBLIC_API_URL=https://api.swiftchain.com
-```
-
----
-
-## Common Issues & Solutions
-
-### Issue: "Cannot GET /forgot-password"
-
-**Solution:** The forgot password page isn't implemented yet. This is out of scope for this task but can be implemented similarly.
-
-### Issue: "API request fails"
-
-**Solution:** Ensure your backend is running at the `NEXT_PUBLIC_API_URL` and the `/api/auth/login` endpoint is available.
-
-### Issue: "Token not stored"
-
-**Solution:** Check browser console and verify localStorage is accessible (not in private/incognito mode).
-
-### Issue: "Redirect doesn't work"
-
-**Solution:** Ensure `/dashboard` route exists. Currently redirects to dashboard layout which should be implemented.
-
----
-
-## Performance Metrics
-
-- **Form Load Time:** < 100ms
-- **Validation Response:** < 10ms
-- **API Call:** Depends on backend (typically < 500ms)
-- **Bundle Impact:** < 5KB gzipped
-- **Re-renders:** Optimized with useCallback
-

-# Toast Notification System - Implementation Summary
-
-## Overview
-
-Implemented a global toast notification system with custom styled variants (Success, Error, Info, Loading) using Sonner. The system integrates backend API for notification configuration and auto-dismisses toasts after 4 seconds.
-
-## Implementation Details
-
-### Architecture: Component → Hook → Service Pattern ✓
-
-#### 1. **Service Layer** (`lib/toast.ts`)
-
-- **Responsibility**: Manages toast notifications and backend API integration
-- **Key Features**:
-  - Singleton service for centralized toast management
-  - Event subscription pattern for listeners
-  - API integration for fetching toast configurations
-  - Support for marking notifications as read
-  - Type-safe interfaces
-- **Methods**:
-  - `success()`: Show success toast
-  - `error()`: Show error toast
-  - `info()`: Show info toast
-  - `loading()`: Show loading toast
-  - `subscribe()`: Subscribe to toast events
-  - `fetchToastMessages()`: Fetch from backend API
-  - `getToastConfig()`: Get toast configuration
-  - `markAsRead()`: Mark notification as read
-- **Features**:
-  - Default 4-second auto-dismiss duration
-  - Loading toasts never auto-dismiss (duration: 0)
-  - Optional action buttons
-  - Optional descriptions
-
-#### 2. **Custom Hook** (`hooks/useToast.ts`)
-
-- **Responsibility**: Provides React component access to toast functionality
-- **Exposed API**:
-  - `success()`: Trigger success toast
-  - `error()`: Trigger error toast
-  - `info()`: Trigger info toast

-  - `fetchNotifications()`: Fetch notifications from API
-  - `notifications`: Array of fetched notifications
-  - `isLoading`: Loading state during API fetch
-- **Features**:
-  - Easy-to-use methods for components
-  - Automatic API data fetching capability
-  - Built-in loading state
-  - Auto-shows urgent notifications (error, loading) from API
-
-#### 3. **Provider Component** (`components/providers/ToastProvider.tsx`)
-
-- **Responsibility**: Renders the global toaster and manages UI
-- **Features**:
-  - Wraps app with Sonner's Toaster
-  - Custom styled toast variants:
-    - **Success**: Green icon, success styling
-    - **Error**: Red icon, error styling
-    - **Info**: Blue icon, information styling
-    - **Loading**: Spinning icon, loading state
-  - Responsive positioning (bottom-right)
-  - Dark mode ready (can be enhanced)
-  - Smooth animations and transitions
-  - Close button for all toasts
-  - Rich color support
-
-#### 4. **Integration** (`app/layout.tsx`)
-
-- Wrapped root layout with ToastProvider
-- ToastProvider surrounds all app content
-- Ensures toast system is globally available

-
-   ```json
-   {
-     "success": true,
-     "message": "Notifications fetched",
-     "data": [
-       {
-         "id": "notif-1",
-         "variant": "info",
-         "title": "System Update",
-         "message": "A new version is available",
-         "dismissible": true,

-# Global Top Loader System - Implementation Summary
-
-## Overview
-
-Implemented a global top loader (progress bar) system that provides visual feedback during App Router navigations in the SwiftChain Frontend application.
-
-## Implementation Details
-
-### Architecture: Component → Hook → Service Pattern
-
-The implementation strictly follows the layered architecture pattern as required:
-
-#### 1. **Service Layer** (`services/topLoaderService.ts`)
-
-- **Responsibility**: Manages router event subscriptions and state management
-- **Key Features**:
-  - Singleton pattern for single instance across the app
-  - Subscribes to route navigation events (popstate, link clicks)
-  - Emits loading state changes to all listeners
-  - Auto-completion delay (500ms) for smooth UX
-  - SSR-safe (guards against server-side execution)
-- **Methods**:
-  - `initialize()`: Sets up router event listeners (called once)
-  - `subscribe(callback)`: Returns unsubscribe function for cleanup
-  - `cleanup()`: Graceful teardown on unmount
-
-#### 2. **Custom Hook** (`hooks/useTopLoader.ts`)
-
-- **Responsibility**: Provides React component access to loader state
-- **Key Features**:
-  - Returns `boolean` loading state
-  - Initializes service on first use
-  - Manages subscription lifecycle
-  - Proper cleanup on component unmount
-- **Usage**: `const isLoading = useTopLoader();`
-
-#### 3. **UI Component** (`components/ui/TopLoader.tsx`)
-
-- **Responsibility**: Renders the visual progress bar
-- **Key Features**:
-  - Fixed position at top of viewport (z-index: 50)
-  - Primary brand color (#3b82f6)
-  - Smooth transitions (300ms duration)
-  - Accessible with ARIA labels
-  - Optional shadow effect for visual depth
-  - Appears on loading, fades on completion
-
-#### 4. **Integration** (`app/layout.tsx`)
-
-- Added `<TopLoader />` as the first element in the root layout
-- Ensures it renders above all other content
-- Global availability across all pages and routes
-
-## Files Created/Modified
-
-### New Files
-
-- ✅ `services/topLoaderService.ts` - Service layer (86 lines)
-- ✅ `hooks/useTopLoader.ts` - Custom hook (26 lines)
-- ✅ `components/ui/TopLoader.tsx` - UI component (40 lines)
-
-### Modified Files
-
-- ✅ `app/layout.tsx` - Added TopLoader import and component
-
-## Visual Features
-
-### Progress Bar Styling
-
-- **Position**: Fixed at top of viewport
-- **Height**: 4px (h-1 in Tailwind)
-- **Color**: Primary brand color (#3b82f6)
-- **Animation**: Smooth fade in/out with 300ms transition
-- **Shadow**: Subtle gradient shadow below the bar for depth
-- **Z-Index**: 50 (above most content, below modals if needed)
-
-### Behavior
-
-1. **Initialization**: Automatically starts when navigation begins
-2. **Loading**: Progress bar expands to full width with full opacity
-3. **Completion**: Automatically shrinks and fades after 500ms
-4. **Error Handling**: Gracefully handles failed navigations
-
-## Acceptance Criteria Met
-
-✅ **Progress bar appears strictly on route changes**
-
-- Triggers on internal link navigation and popstate events
-- SSR-safe implementation
-
-✅ **Strict Layered Architecture (Component → Hook → Service)**
-
-- Clear separation of concerns
-- Service manages logic
-- Hook provides state
-- Component handles rendering
-- Easy to test and maintain
-
-✅ **Uses primary brand color**
-
-- Utilizes tailwind primary color (#3b82f6)
-- Responsive to theme changes
-

-
-## 🎯 Interaction Patterns
-
-### Pattern 1: Single Filter Application
-```
-User selects Status → URL updates → Data refetches → List updates
-```
-
-### Pattern 2: Multi-Filter Application
-```
-User applies search
-User changes status
-User selects sort
-(All while others remain active)
-→ URL has ?search=X&status=Y&sortBy=Z
-→ Data refetches with all filters
-→ List updates with fully filtered data
-```
-
-### Pattern 3: Filter Modification
-```
-Current: ?search=TRK&status=DELIVERED
-User changes status to PENDING
-→ URL becomes: ?search=TRK&status=PENDING
-→ Old data cleared
-→ New filtered data fetched
-→ List updates
-```
-
-### Pattern 4: Filter Clearing
-```
-Current: ?search=TRK&status=DELIVERED&sortBy=date-desc
-User clicks "Clear Filters"
-→ URL becomes: /deliveries
-→ All filter values reset to undefined
-→ useDeliveries receives empty object
-→ API called without filters
-→ All deliveries returned
-→ List updates to show everything
-```
-
----
-
