@ltikit/adapter-redis

Redis / Upstash NonceStore adapter for LTIkit — ideal for serverless, where in-memory state can't enforce single-use nonces across cold invocations. Single-use is enforced by an atomic GETDEL.

Redis holds the nonce store only. Platforms are durable config — pair this with @ltikit/adapter-supabase (or your own) for the PlatformStore. Requires @ltikit/core.

npm i @ltikit/core @ltikit/adapter-redis

Usage

import { redisNonceStore, fromUpstash } from '@ltikit/adapter-redis'
import { Redis } from '@upstash/redis'

export const lti = createLti({
  keys: staticKeyStore({ /* ... */ }),
  nonces: redisNonceStore(fromUpstash(Redis.fromEnv())),
  platforms: supabasePlatformStore(client), // or your own
})

No hard dependency on any Redis client — redisNonceStore takes a structural RedisLike (set with TTL + atomic getdel). Ships adapters for the common clients:

import { fromUpstash, fromIoRedis, fromNodeRedis } from '@ltikit/adapter-redis'
