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 });

Running tests

To run the unit tets, Docker must be running. Containers for Redis and Redis Cluster will be started so that tests can run against them.

npm run test:docker
