How can I troubleshoot caching issues in Node.js?

I'm having trouble with caching in my Node.js application. What should I check first?

First, ensure that your caching mechanism is properly configured. Are you using a library like Redis or in-memory caching?

I'm using Redis for caching, but it seems like the data isn't being updated as expected.

Check if your cache expiration settings are correct. Also, verify that you're invalidating the cache when data changes.

How can I manually clear the cache in Redis?

You can use the command FLUSHALL to clear all keys in Redis, or DEL <key> to delete specific keys.

Thanks! What are some common pitfalls to avoid with caching?

Common pitfalls include not setting appropriate expiration times, failing to invalidate cache on updates, and over-caching.
