Question: caching query results (memory, redis, etc.)

Quick question: how do you guys cache your mongoose query results?
I know mongodb is supposed to be fast et al, but some heavy queries (like aggregate) in some use-cases benefit a lot from in-memory or redis result caching.
There are some existing npm packages to do that, but they are all failing to do the job correctly. And they are all obscure 12 stars, not updated since 2014, monkey-patching codebase.

Caching is such an important matter in software engineering, that I'm wondering why there is no "official" way to do that in mongoose.

No source files, tests, or entry points are named. Start by clarifying the expected caching API and supported memory or Redis behavior, then review how Mongoose exposes query and aggregate execution; done would require an agreed official caching design rather than a narrowly scoped edit.
