feather-cache

feather-cache v1.3.1 is a lightweight pluggable key-value cache supporting multiple storage backends (in-memory, MongoDB, IndexedDB). Released under MIT license with low release cadence (last update ~2019). It differentiates from simpler caches like lru-cache by allowing custom drivers for persistent storage. Built-in TypeScript types. The in-memory driver is for convenience; for serious in-memory caching, lru-cache is recommended. Supports async get/set/delete with optional TTL per key.
