What is the motivation / use case for changing the behavior?

Supporting a simple in-memory cache provider out of the box would be a great, useful feature. Probably as an external installable package, i.e. @nest/cache. See https://docs.microsoft.com/en-us/aspnet/core/performance/caching/memory?view=aspnetcore-2.0 for an example.

https://www.npmjs.com/package/node-cache would probably be an ideal package to support "under the hood" of the Nest provider.

I'd be happy to write this provider if you think it's a good idea, @kamilmysliwiec.

[kamilmysliwiec]

Yeah, go for it! Maybe, let's create an interceptor that we could even put in the @nestjs/common as a built-in interceptor. CacheInterceptor sounds quite good :)

CacheModule just landed in 5.3.0. Read more here https://docs.nestjs.com/techniques/caching

it wold be nice to have Method level @Cache annotation as well for service methods

@Injectable()
export class ProductService {
 @Cache(myStore, { ttl: 60 })
    public async getProducts(): Promise<string[]> {
        // return seed data from database
        return [...];
    }
}

Is there a way to expose some generic cache (CacheStore) to have get and set methods to cache any arbitrary data?!

[kyle-mccarthy]

@danil-z I was able to do this by injecting the cache manager into my cache service, you can checkout an example at https://github.com/kyle-mccarthy/nest-next-starter/blob/master/src/cache/cache.service.ts

@danil-z this issue has been closed, it would be great to make another issue for this request.

@kamilmysliwiec how to invalidate cache ?

common use case

1. api method getUser -> cache
2. api method updateUser -> invalidate cache

only manually ?
