I built a multi-layer caching library for Node.js — would love your feedback!

Hey dev.to community! 👋 I've been working on a side project for a while now and finally got it to a point where I feel comfortable sharing it publicly. It's called layercache — a multi-layer caching toolkit for Node.js. I'd really appreciate any feedback, honest criticism, or ideas from folks who deal with caching in production. Here's the quick overview: Why I built this Almost every Node.js service I've worked on eventually hits the same caching problem: Memory-only cache → Fast, but each instance has its own isolated view of data Redis-only cache → Shared across instances, but every request still pays a network round-trip Hand-rolled hybrid → Works at first, then you need stampede prevention, tag invalidation, stale serving, observability... and it spirals fast I couldn't find a library that handled all of this cleanly in one place, so I built one. What layercache does layercache lets you stack multiple cache layers (Memory → Redis → Disk) behind a single unified API. On a cache hit
