@flaghoist/adapter-redis

Store Flaghoist flags in Redis. Works with ioredis on Node and with Upstash on the edge, because it only needs a client that can get, set, delete and scan.

npm install @flaghoist/adapter-redis

On Node with ioredis:

import { redisAdapter } from '@flaghoist/adapter-redis'
import { Redis } from 'ioredis'

createFlagServer({
  storage: redisAdapter(new Redis(process.env.REDIS_URL)),
  auth: {/* ... */},
})

On Cloudflare Workers with Upstash, where a TCP connection is not an option:

import { Redis } from '@upstash/redis/cloudflare'

createFlagServer((env) => ({
  storage: redisAdapter(Redis.fromEnv(env)),
  auth: {/* ... */},
}))

Pick this over Cloudflare KV when you want changes to be visible immediately everywhere, rather than a few seconds later. Pick KV when you would rather not run anything.

Webhook endpoints (if you use them) live in their own hash, flaghoist:webhooks by default. Change it with { webhookHashKey: '...' }.

Validated by the same conformance suite as the other adapters.

Status

Pre-alpha, built and maintained by one person. The API can still change without notice, and production use is not recommended yet. If you try it and something breaks, an issue is genuinely useful.

Apache-2.0. Part of Flaghoist.
