@bhooai/nexus-cache

Redis wrapper, cache-aside, pub/sub, and the Redis-backed rate-limit backend.

Exports

• Cache — new Cache({ url, keyPrefix }). get/set/del/incr with TTL, cache-aside helpers, graceful no-op when Redis is unavailable.
• RateLimiter — new RateLimiter({ windowMs, max }) (Redis-backed; in-memory fallback in nexus-auth).
• PubSub — publish/subscribe for WS fanout and inter-process events.

Usage

import { Cache } from '@bhooai/nexus-cache';
const cache = new Cache({ url: 'redis://localhost:6379', keyPrefix: 'app' });
await cache.set('k', 'v', { ttl: 60 });
const v = await cache.get('k');
await cache.close();

Redis is optional: if the URL is unreachable the cache degrades to misses and the server keeps running. Tests use a real Redis via .env (NEXUS_REDIS_URL).
