How do you use Redis for caching in a Node.js application?

Description : Explain how Redis can be used for caching data in a Node.js application.

Answer :

Redis can be used for caching in a Node.js application by storing frequently accessed data in memory. Install the `redis` library using `npm install redis`. Connect to Redis and use `redis.set()` to store data and `redis.get()` to retrieve it. Cache responses from slow operations or database queries to reduce latency and improve performance.

To implement Redis-based session management in a Node.js application, use the `express-session` and `connect-redis` libraries. Install them with `npm install express-session connect-redis redis`. Configure `express-session` to use `connect-redis` as the session store, specifying Redis connection options. This setup stores session data in Redis, which can be useful for scaling applications and ensuring session persistence across multiple servers.
