What Next?

To expand on this project you could implement the following features and improvements:

Authentication and Authorization
- Implement JWT-based user authentication, including registration and login routes.
- Introduce Role-Based Access Control (RBAC) to restrict access to certain routes based on user roles (e.g., admin, user).
Advanced Redis Features
- Utilize Redis Pub/Sub for real-time updates, enabling live communication such as updates to restaurant data or reviews.
- Explore Redis Streams for event sourcing to record all changes as events.
Improved Caching Strategies
- Implement cache invalidation by setting appropriate expiration times and automatically updating the cache when underlying data changes.
Real-Time Features with WebSockets
- Integrate Socket.IO to add real-time functionalities like live chat, notifications, or live updates of reviews.
