## What it is
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

- artifact type: library
