layered-cache

A hierarchical cache manager for Node.js that chains multiple cache layers (e.g., in-memory LRU, database, remote server) with automatic fallback and propagation. v4.0.2 is the current stable release, with infrequent updates. Key differentiator: supports arbitrary key types, optional multi-get/set, and a customizable not-found check. The library is ESM-only and requires Node >=10.
