async-disk-cache

Async disk cache library for Node.js (v2.1.0, stable, low maintenance). Stores cache entries as files in a temporary directory (default $TMPDIR/<username>). Provides promise-based async API with compression support (gzip, deflate, deflateRaw) and optional buffer support. Differentiated from sync-disk-cache by async operations; a lightweight alternative to full-featured caching solutions like node-cache-manager. No external dependencies. Actively used in Ember CLI ecosystem.
