buffering-cache

Node.js cache wrapper that asynchronously refreshes cached entries to minimize cache misses and prevent staleness. Current version 2.2.1 releases maintain a steady cadence. Requires ioredis for Redis backend and optionally supports multi-level caching with lru-cache for local memory. Key differentiator: proactive buffer-based refresh strategy rather than passive expiry, keeping hot data fresh with zero additional latency.
