node-cache is a simple, fast in-memory caching module for Node.js with set, get, and delete methods that works like memcached. Keys support TTL-based expiration and are stored in a single object, with a practical limit of around one million keys.

Use cases

• cache api responses in memory with ttl expiration
• store computed values in a node process to avoid recomputation
• replace an external memcached dependency for simple local caching
• rate-limit or deduplicate requests within a single node server
• cache database query results in-process

When to choose

• you need a lightweight, dependency-free in-memory cache for a single Node.js process
• you want memcached-like set/get/delete semantics with key TTLs
• your dataset fits in memory (up to roughly 1m keys)

When to avoid

• you need a distributed cache shared across multiple processes or servers
• you need persistence or eviction policies like LRU
• you want an actively maintained project - the maintainers state it is unmaintained
