Keyv-anyredis NPM

keyv-anyredis

Zero-dependency storage adapter for Keyv that works with many different Redis clients and supports cluster mode

Why use this?

This adapter does more than the official @keyv/redis adapter. This adapter can be used with Redis cluster mode — the official adapter cannot. Of course it can also be used with standard, non-cluster, Redis servers.

This adapter also works with many Redis clients, whereas the official adapter bundles a specific version of ioredis.

✅ Works with standard Redis servers
✅ Works Redis cluster servers
✅ Works with ioredis and many other Redis clients
✅ Passes all tests in the Keyv test suite

Tested clients

keyv-anyredis works with any Redis client that implements a standard callback or Promise interface, including the two most popular clients, ioredis and node-redis.

We test with the the Keyv test suite, and we test with both a standard Redis server and a Redis cluster. If you are familiar with Redis cluster, you may know that many utlities that claim to be compatible with clusters, are not. keyv-anyredis really is compatible and is tested against a cluster running in a Docker container.

Client	Compatible?	Notes
redis	✅ Yes	Also known as node-redis; works with version 3 and the new version 4, which adds support for cluster mode; works in Promise mode or legacy callback mode
ioredis	✅ Yes	Works great in standard and cluster mode
fakeredis	✅ Yes
fast-redis-cluster2	✅ Yes	Cluster mode
handy-redis	✅ Yes	To use this client, pass `client.nodeRedis` to the `KeyvAnyRedis` constructor
noderis	⛔️ No	`smembers` is missing
redis-clustr	✅ Yes	Cluster mode
tedis	✅ Yes	To use this client, cast the client to `CompatibleRedisClient` in TypeScript
thunk-redis	✅ Yes	Set `usePromise: true`; works in standard and cluster mode
xredis	✅ Yes

Install

npm i keyv-anyredis

Usage

const Keyv = require('keyv');
const { KeyvAnyRedis } = require('keyv-anyredis');

// Create a client here, using ioredis, redis, or any
// compatible library.
//
// For example, to create a cluster client using ioredis as
// described at https://github.com/luin/ioredis#cluster:
//
// const Redis = require('ioredis');
// const client = new Redis.Cluster(…cluster configuration…);

const store = new KeyvAnyRedis(client);
const keyv = new Keyv({ store });
