How to automatically clear redis route cache when building a new version?

[vuthanhbayit]

Hello. After publishing a new version for the web, I want to automatically clear all route cache data on redis. Does anyone know how to do that?

Yes, there are several approaches:

You can use the FLUSHALL command directly on redis, for example using redis-cli: https://redis.io/docs/latest/commands/flushall/

You can purge everything via this module's API:
https://nuxt-multi-cache.dulnan.net/features/api#purge-everything

Or you can implement the buildCacheKey method in the module's serverOptions: https://nuxt-multi-cache.dulnan.net/features/route-cache#cache-key-for-routes
This method is called to determine the key for the route cache item. You could add a version number or build/commit hash to this key that changes for every new version. By doing that you don't directly purge the cache. However you will make sure that after every deployment you won't be serving cached routes from before the deployment, since the key is now different.
