Auto cache invalidation engine — declare reverse dependencies between cache tags and data keys; when models change, you receive the exact tags to purge (Redis, CDN, in-memory, etc.).

Install

npm install @mr-aftab-ahmad-khan/cacheflow

Example

import { cacheflow } from "@mr-aftab-ahmad-khan/cacheflow";

const graph = cacheflow();

graph.track("GET /v1/orgs/:id/dashboard", [`Org:${orgId}`, `User:${ownerId}`]);
graph.track("GET /v1/posts/:slug", [`Post:${postId}`, `Org:${orgId}`]);

async function onOrgWrite(orgId: string, redis: { del: (k: string) => Promise<unknown> }) {
  const bust = graph.invalidateDeps(`Org:${orgId}`);
  await Promise.all([...bust].map((tag) => redis.del(tag)));
}
