Cache

Standalone — usable in any Node project, no @warlock.js/core required.

@warlock.js/cache is the caching layer. Pick a driver — memory, Redis, Postgres, file, LRU, or null — then wrap the slow thing in remember and move on:

import { cache, RedisCacheDriver } from "@warlock.js/cache";

cache.setCacheConfigurations({
  default: "redis",
  drivers: { redis: RedisCacheDriver },
  options: { redis: { url: process.env.REDIS_URL } },
});
await cache.init();

// First call computes and stores; the next 999 within the hour are ~1ms reads.
const product = await cache.remember(
  `products.${productId}`,
  "1h",
  () => db.products.findById(productId),
);

That one call is stampede-safe by default: when a thousand requests miss the same key at once, exactly one regenerates it while the rest wait for the result. Tag related entries for surgical invalidation, lock against races with cache.lock, serve stale-while-revalidate for hot reads, even cache by vector similarity for AI-adjacent workloads — each is one short call away.
