What are the best caching strategies in Node.js?

There are several effective caching strategies in Node.js, including in-memory caching, file caching, and using external caching systems like Redis or Memcached.

Can you explain in-memory caching?

In-memory caching stores data in the server's RAM, allowing for faster access. It's ideal for frequently accessed data but can be limited by memory size.

What are the pros and cons of using Redis for caching?

Redis offers high performance and persistence, but it adds complexity and requires additional resources to manage.

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

You can use libraries like node-cache for in-memory caching or connect to Redis using the redis package. Would you like a code example?
