clean-cache

Clean Cache is a minimal in-memory JavaScript cache with TTL (time-to-live) support, packaged as a single file with zero dependencies. Current stable version is 1.0.2. It offers a simple API with `add`, `retrieve`, `count`, and `tidy` methods, and validates keys to prevent null/undefined. Unlike larger caching libraries (e.g., node-cache, lru-cache), it keeps dependencies to a minimum and is fully tested. Suitable for small Node.js projects needing a lightweight, ephemeral cache.
