What is layercache and how does it work?

Layercache is a Node.js library stacking cache layers like memory, Redis, disk. Hits from fastest; misses fetch once, backfill all.

Is layercache better than cache-manager?

Potentially—built-in stampede protection, tags, observability. But less mature; test for your stack.

How to install and use layercache in production?

npm i layercache. Stack layers, add fetcher. Monitor metrics; start small, scale with Redis.

Layercache: The Node.js Caching Stack That Might Actually Save Your Sanity (Or Not)

100 concurrent requests for the same key, and layercache triggers just one fetcher execution. That's the promise from this new Node.js library—but after 20 years watching cache hype, I'm not sold yet.
