What are the best practices for caching in Node.js?

Caching in Node.js can significantly improve performance. Some best practices include using in-memory caching, setting appropriate cache expiration times, and leveraging distributed caching solutions like Redis.

Can you explain in-memory caching and its benefits?

In-memory caching stores data in the server's RAM, allowing for faster access compared to disk storage. It reduces latency and improves response times for frequently accessed data.

What tools can I use for caching in Node.js?

Popular tools for caching in Node.js include Redis, Memcached, and Node-cache. Each has its own strengths depending on your use case.

How do I implement Redis caching in my Node.js application?

To implement Redis caching, you can use the 'redis' package. First, install it using npm, then create a Redis client and use it to set and get cached data.
