How to revalidate cache e.g. when some1 made make a get request to get data then a post request updating a database row, and then he immediately make a get request to get data? He will receive a cached data, not the updated one with post.

Great tutorial! Tnx man!

For those who are struggling with cache not working try to downgrade cache-manager pkg to version 4.1.0, current 5.X version is not compatible with NestJS 8.

Thanks man, so does this mean when I deploy my API I would need to install redis on my server as well? ..

[ashishkumari-yggn]

I getting an error at option - store :redisStore

Hi @Michael Guay, Do "Auto-caching responses" and "redis store" work together? I tried, somehow, it did not use the redis as the store still?

[oleksii.shkulipa]

can you please help ? how much can i cached data by this method ? and where will those data be placing ?
And what about Redis, which method will be better use for caching between cacheManager and Redis ?
Thx

Does TTL also gets saved as part of Redis? I mean if we restart the server, does the TTL reset or no?

Thank you for this video. How do we determine if the Redis cache should be implemented with cache-manager or with a microservice?
