rate-limiting-abuse-protection

Implement rate limiting in Express.js using the express-rate-limit middleware to set custom request thresholds per route, IP address, or user, preventing API abuse and ensuring stable service availability.

Yes, Redis supports sliding window rate limiting strategies. Combined with the ioredis client, you can track request timestamps and enforce strict request caps to mitigate DDoS attacks and resource exhaustion.

The best way to protect a login endpoint from brute-force attacks is applying granular rate limiting, such as allowing only 5 attempts per user every 15 minutes, blocking suspicious IPs before they exhaust resources.

Yes, this approach supports per-route policies and token buckets. It includes advanced strategies like fixed windows, sliding windows, token buckets, and leaky buckets for flexible API security and abuse prevention.

You need ioredis and express-rate-limit for API security because express-rate-limit handles middleware request tracking, while ioredis provides distributed storage to maintain accurate rate limit counters across multiple server instances.

You should not use a single global rate limit when endpoints have varying sensitivity levels. Instead, apply granular per-route policies, enforcing strict caps on sensitive endpoints like login while keeping lenient limits on others.
