Answer
Use Redis or a distributed store for counters. Implement token bucket, sliding window, or leaky bucket algorithms across nodes.
Quick Answer
Distributed rate limiting across multiple Node.js instances requires a shared counter store. Use Redis with atomic increment (INCR + EXPIRE) or Redis sorted sets for sliding window rate limiting. All Node.js instances read/write the same Redis counter, so limits are enforced consistently regardless of which instance handles the request.
