Admin Navigation Implementation - Completed

Date: November 20, 2025 Status: ✅ COMPLETE Related Plans: Plan 12 Supplement - Admin Navigation Menu

📋 Summary

Successfully implemented an "Admin" dropdown menu in the main navigation bar that:

• ✅ Appears only to users with ADMIN role
• ✅ Located after "Blogs" in the navigation menu
• ✅ Provides quick access to all admin management pages
• ✅ Protects admin routes with middleware
• ✅ Integrates seamlessly with existing header design

🔧 Implementation Details

1. Menu Data Updated

File: src/context/menuData.ts

Added Admin menu item with submenu:

{
  id: 8,
  title: "Admin",
  newTab: false,
  path: "/",
  submenu: [
    { id: 81, title: "Products", path: "/admin/products" },
    { id: 82, title: "Categories", path: "/admin/categories" },
    { id: 83, title: "Images", path: "/admin/images" },
    { id: 84, title: "Dashboard", path: "/admin" },
  ],
}

2. Header Component Updated

File: src/components/layout/Header/index.tsx

Added filtering logic after session declaration:

// Filter menu items to hide Admin from non-admin users
const visibleMenuItems = menuData.filter((item) => {
  if (item.title === "Admin") {
    return session && session.user && (session.user as any).role === "ADMIN";
  }
  return true;
});

Changed menu rendering from menuData.map() to visibleMenuItems.map() at line 410.

3. Route Protection Middleware

File: src/middleware.ts (NEW)

Created middleware to protect /admin/* routes:

import { NextRequest, NextResponse } from "next/server";
import { auth } from "@/app/api/auth/[...nextauth]/route";

export async function middleware(request: NextRequest) {
  if (request.nextUrl.pathname.startsWith("/admin")) {
    const session = await auth();

    // Redirect to login if not authenticated
    if (!session) {
      return NextResponse.redirect(new URL("/signin", request.url));
    }

    // Redirect to home if not admin
    const userRole = (session.user as any)?.role;
    if (userRole !== "ADMIN") {
      return NextResponse.redirect(new URL("/", request.url));
    }
  }

  return NextResponse.next();
}

export const config = {
  matcher: ["/admin/:path*"],
};

4. NextAuth Configuration

File: src/app/api/auth/[...nextauth]/route.ts

✅ Already configured correctly with:

• JWT callback that fetches user role from database
• Session callback that adds role to session object
• User role available in session as session.user.role

Type Definitions: src/types/next-auth.d.ts - Already includes role in Session, JWT, and User interfaces

🧠 How It Works

For Non-Admin Users:

1. User navigates site
2. "Admin" menu item is not visible in header
3. If they try to access /admin/* URL directly
4. Middleware redirects to login or home page

For Admin Users:

1. User with ADMIN role logs in
2. Session includes role: "ADMIN"
3. Header filtering shows "Admin" menu item
4. Can click to see submenu with 4 options:
   • Products (/admin/products)
   • Categories (/admin/categories)
   • Images (/admin/images)
   • Dashboard (/admin)
5. All routes protected by middleware

🔐 Security Features

✅ Authentication Check: Non-logged-in users redirected to /signin ✅ Authorization Check: Non-admin users redirected to / ✅ Role Verification: Middleware verifies ADMIN role from session ✅ Session Validation: NextAuth includes role in JWT and session ✅ Route Protection: All /admin/* routes protected automatically

✅ Verification Checklist

• ✅ Admin menu item added to menuData.ts (id: 8)
• ✅ Header component filters menu based on user role
• ✅ Middleware created and configured
• ✅ Middleware matches /admin/:path* routes
• ✅ NextAuth already includes role in session
• ✅ Type definitions include role (next-auth.d.ts)
• ✅ Menu uses visibleMenuItems instead of menuData
• ✅ Filter logic checks for ADMIN role

🧪 Testing

Test 1: Non-Admin User

1. Create/use non-admin user account
2. Login
3. Verify "Admin" menu item is NOT visible
4. Try accessing /admin/products directly
5. Should redirect to home page

Test 2: Admin User

1. Create/use admin user account (role: "ADMIN")
2. Login
3. Verify "Admin" menu item IS visible after "Blogs"
4. Click "Admin" to see submenu
5. Verify 4 links appear (Products, Categories, Images, Dashboard)
6. Click each link and verify they load
7. Navigate away and come back - should stay logged in

Test 3: Route Access

1. Non-admin user tries /admin/products
2. Should redirect to / (home page)
3. Admin user tries /admin/products
4. Should load products page successfully

🚀 What's Available Now

Admin Menu Links:

• Products (/admin/products) - List, create, edit products
• Categories (/admin/categories) - Manage product categories
• Images (/admin/images) - Image audit and gallery
• Dashboard (/admin) - Admin overview (from Plan 12)

Related Functionality:

• Image upload with automatic thumbnail generation
• Product management (CRUD)
• Category hierarchy management
• Missing images audit report

📊 Integration Status

🎯 Next Steps

1. Test the implementation:

   • Login as admin user
   • Verify "Admin" menu appears
   • Click links and test functionality

2. Create test admin account (if needed):

   • Register user or use database to set role: "ADMIN"

3. Verify all admin pages work:

   • /admin/products
   • /admin/categories
   • /admin/images
   • /admin (dashboard)

4. Test non-admin access:

   • Login as non-admin
   • Verify menu doesn't show
   • Verify routes redirect properly

✨ Benefits

✅ Clean, integrated admin navigation ✅ Role-based visibility (only shows for admins) ✅ Protected routes (middleware prevents unauthorized access) ✅ Seamless UX (matches existing design patterns) ✅ Easy to extend (can add more menu items) ✅ Type-safe (TypeScript support for roles)

Implementation Complete! 🎉

The admin navigation system is fully integrated and ready for use. All admin pages created in Plan 12 are now accessible via the navigation menu and protected by middleware.
