exp-asynccache

An async cache for Node.js (v3.2.0) that provides a lookup function per key with callback and promise support. Released under the ExpressenAB organization. Differentiates from similar libraries like async-cache by not caching errors, always calling the callback asynchronously, and allowing per-key TTL via additional arguments to the resolve function. Uses lru-cache by default but supports any compatible cache interface. Stable maintenance mode; low release cadence.
