How can I troubleshoot caching issues in my Express app?
First, can you describe the specific caching issue you're facing? Are you using any caching middleware?
Yes, I'm using Redis for caching, but some data isn't updating as expected.
It sounds like there might be a stale cache. Have you tried setting appropriate cache expiration times?
I haven't set expiration times. How do I do that?
You can set expiration times in Redis using the EXPIRE
command or when you set the cache, like this: client.set(key, value, 'EX', seconds);
