A simple in-memory key-value cache library for Node.js with optional TTL-based expiration and timeout callbacks. It supports multiple cache instances, JSON export/import, and basic hit/miss statistics.

Use cases

• cache api responses in memory
• store computed values with a ttl
• memoize expensive function results in node
• add a simple key-value cache without external dependencies
• expire cached entries after a timeout with a callback
• export and restore cache contents as

When to choose

• you need a lightweight, zero-dependency in-memory cache for a single node process
• you want simple put/get/del semantics with optional expiration
• you don't need persistence, clustering, or eviction policies

When to avoid

• you need a distributed or shared cache across processes (use Redis or Memcached)
• you need LRU/LFU eviction or size limits
• you need persistence or high read/write throughput under heavy load
