UsefulKey

Redis

Redis-backed keystore adapter.

Overview

  • Redis-backed keystore storing each record in a Redis hash keyed by id.
  • Maintains a secondary mapping from key hash to id for fast findKeyByHash.

Usage

import { createClient } from "redis";
import { RedisKeyStore, usefulkey } from "betterkey";

const client = createClient({ url: process.env.REDIS_URL });
await client.connect();

const keyStore = new RedisKeyStore(client, { keyPrefix: "usefulkey" });

const uk = usefulkey({ adapters: { keyStore } });
