Express Throttle Redis

Redis storage adapter for express-throttle rate-limiting middleware for Express. Current version 0.0.4, released as an early-stage package with no recent updates. Provides a Redis-backed store for throttling rate limits across distributed Node.js servers. Unlike default in-memory stores, it allows shared state across multiple processes or machines via Redis. However, it does not implement key expiration, so memory grows unbounded; requires manual Redis configuration with LRU eviction. Alternative: use express-rate-limit with rate-limit-redis, which has more active maintenance and built-in key expiry.
