# Admin Panel Navigation & Session Management Fix

## Problem

When clicking on navigation items in the admin panel's left sidebar or live tiles, users were being signed out or redirected to the login page.

## Root Cause

1. Each admin page had its own `checkAuth()` function making redundant API calls
2. Multiple simultaneous authentication checks could interfere with session management
3. No centralized authentication handling across admin pages
4. Missing public API routes for frontend to consume published content

## Solution Implemented

### 1. Centralized Authentication (`/admin/js/auth.js`)

Created a shared authentication utility that:

- Provides a single `checkAuth()` function used by all admin pages
- Handles session validation with `/api/admin/session` endpoint
- Manages authentication state globally via `window.adminAuth`
- Provides shared `logout()`, `showSuccess()`, and `showError()` functions
- Automatically checks authentication on page load (except login page)

### 2. Updated All Admin Pages

Modified all HTML pages to include the shared `auth.js` script:

- ✅ `/admin/dashboard.html`
- ✅ `/admin/homepage.html`
- ✅ `/admin/products.html`
- ✅ `/admin/portfolio.html`
- ✅ `/admin/blog.html`
- ✅ `/admin/pages.html`
- ✅ `/admin/menu.html`
- ✅ `/admin/settings.html`
- ✅ `/admin/users.html`

### 3. Updated JavaScript Files

Removed duplicate `checkAuth()` functions from individual JS files and updated to use the shared version:

- ✅ `products.js` - Product management
- ✅ `homepage.js` - Homepage editor
- ✅ `blog.js` - Blog post management
- ✅ `portfolio.js` - Portfolio project management
- ✅ `pages.js` - Custom pages management
- ✅ `settings.js` - Site settings
- ✅ `users.js` - User management
- ✅ `menu.html` (inline script) - Menu management

### 4. Enhanced Backend Routes

#### Admin Routes (`/api/admin/*`)

All routes require authentication via `requireAuth` middleware:

**Products:**

- `GET /api/admin/products` - List all products
- `GET /api/admin/products/:id` - Get single product
- `POST /api/admin/products` - Create product
- `PUT /api/admin/products/:id` - Update product
- `DELETE /api/admin/products/:id` - Delete product

**Portfolio:**

- `GET /api/admin/portfolio/projects` - List all projects
- `GET /api/admin/portfolio/projects/:id` - Get single project
- `POST /api/admin/portfolio/projects` - Create project
- `PUT /api/admin/portfolio/projects/:id` - Update project
- `DELETE /api/admin/portfolio/projects/:id` - Delete project

**Blog:**

- `GET /api/admin/blog` - List all blog posts
- `GET /api/admin/blog/:id` - Get single post
- `POST /api/admin/blog` - Create blog post

**Pages:**

- `GET /api/admin/pages` - List all custom pages

#### Public Routes (`/api/*`)

Added/enhanced routes for frontend consumption (no authentication required):

**Products:**

- `GET /api/products` - List active products
- `GET /api/products/featured` - Get featured products
- `GET /api/products/:id` - Get single product

**Portfolio:**

- `GET /api/portfolio/projects` - List active projects

**Blog:**

- `GET /api/blog/posts` - List published posts
- `GET /api/blog/posts/:slug` - Get single post by slug

**Pages:**

- `GET /api/pages` - List published custom pages
- `GET /api/pages/:slug` - Get single page by slug

**Menu:**

- `GET /api/menu` - Get visible menu items

**Homepage:**

- `GET /api/homepage/settings` - Get homepage configuration
- `GET /api/homepage/sections` - Get homepage sections

**Settings:**

- `GET /api/settings` - Get public site settings

## Session Configuration

The backend uses PostgreSQL session storage with these settings:

```javascript
{
  secret: process.env.SESSION_SECRET || "skyart-shop-secret-2025",
  resave: false,
  saveUninitialized: false,
  cookie: {
    secure: process.env.NODE_ENV === "production",
    httpOnly: true,
    maxAge: 24 hours,
    sameSite: "lax"
  }
}
```

## Testing

### Run the Test Script

```bash
cd /media/pts/Website/SkyArtShop/backend
./test-navigation.sh
```

### Manual Testing Steps

1. **Login Test:**
   - Navigate to `http://localhost:5000/admin/login.html`
   - Login with your credentials
   - Verify successful redirect to dashboard

2. **Navigation Test:**
   - Click each item in the left sidebar
   - Verify you remain logged in
   - Verify each page loads correctly with its data

3. **Content Creation Test:**
   - Navigate to Products section
   - Click "Add New Product"
   - Fill in product details
   - Click "Save & Publish"
   - Verify product appears in the list

4. **Frontend Publishing Test:**
   - Create/edit content in admin panel
   - Mark it as "Published" or "Active"
   - View the public API endpoint (e.g., `/api/products`)
   - Verify the content appears

5. **Session Persistence Test:**
   - Login to admin panel
   - Navigate through multiple sections
   - Leave browser open for several minutes
   - Continue navigating
   - Verify session remains active for 24 hours

## How Content Publishing Works

### From Admin to Frontend Flow

1. **Create Content in Admin Panel:**
   - Login to `/admin/`
   - Navigate to any section (Products, Blog, Portfolio, etc.)
   - Click "Create" or "Add New"
   - Fill in details
   - Enable "Active" or "Published" toggle
   - Click "Save & Publish"

2. **Content Stored in Database:**
   - Data saved to PostgreSQL with `isactive=true` or `ispublished=true`
   - Timestamps recorded (createdat, updatedat)

3. **Frontend Accesses via Public API:**
   - Frontend JavaScript calls public endpoints (e.g., `/api/products`)
   - Backend filters for only active/published content
   - JSON data returned to frontend
   - Frontend renders the content dynamically

### Example Flow - Adding a Product

**Admin Panel:**

```
1. Login → Dashboard → Products
2. Click "Add New Product"
3. Enter: Name, Price, Description, Image
4. Toggle "Active" to ON
5. Click "Save & Publish"
6. Backend: POST /api/admin/products
7. Product saved with isactive=true
```

**Frontend:**

```
1. Shop page loads
2. JavaScript: fetch('/api/products')
3. Backend: Returns only products where isactive=true
4. Frontend: Renders product cards with data
5. Customer sees the new product
```

## Troubleshooting

### Issue: Still getting logged out

**Solution:**

- Clear browser cookies and cache
- Verify SESSION_SECRET is set in `.env`
- Check PostgreSQL session table exists
- Restart backend server

### Issue: Content not appearing on frontend

**Solution:**

- Verify content is marked as "Active" or "Published" in admin panel
- Check browser console for API errors
- Verify public routes are accessible (test with curl or browser)
- Check database records have `isactive=true` or `ispublished=true`

### Issue: 401 Unauthorized errors

**Solution:**

- Verify you're logged in
- Check session cookie is being sent (browser DevTools → Network → Headers)
- Verify backend session store is working (check session table in database)
- Try logging out and back in

### Issue: Navigation not working

**Solution:**

- Verify all admin HTML files have `<script src="/admin/js/auth.js"></script>`
- Check browser console for JavaScript errors
- Verify auth.js is accessible at `/admin/js/auth.js`
- Clear browser cache
