http://localhost:3000

---

Caching Strategy (Redis)

• GET requests → Cached in Redis
• POST/PUT/DELETE → Cache invalidation
• Per-event caching → event-attendees:{id}
• Per-user caching → my-registered:{email}

---

Authentication Flow

• User registers / logs in
• JWT token stored in cookies
• Protected routes verify token
• Role-based access control implemented

---

API Highlights

Get All Events

GET /api/events

Register for Event

POST /api/events/:id/register

Get Attendees

GET /api/events/:id/attendees

---

Error Handling

• Custom 404 page using not-found.jsx
• API-level error responses with proper status codes

---

Future Improvements

• Middleware-based authentication
• Pagination & filtering
• Admin dashboard
• Real-time updates (WebSockets)
