@cache-kit/cache-memory

In-process, Map-based CacheProvider for @cache-kit/cache. Zero external dependencies. LRU eviction, TTL sweep, distributed-lock emulation for single-process stampede protection.

npm install @cache-kit/cache @cache-kit/cache-memory

import { Cache } from '@cache-kit/cache';
import { MemoryProvider } from '@cache-kit/cache-memory';

const cache = new Cache({
  provider: new MemoryProvider({
    type: 'memory',
    maxSize: 10_000, // LRU-evict above this many entries
    checkIntervalMs: 60_000, // background sweep for expired entries
  }),
});

Good fit for: single-process apps, local development without a Redis instance, or as the L1 tier of a MultiLevelProvider in front of a shared backend.

Not a fit for: multiple app instances that need to share cached data or coordinate invalidation — use @cache-kit/cache-redis (or another shared backend) for that.
