API Rate Limiting Strategies for Node.js Applications
Rate limiting protects your Node.js API from abuse. Implement token bucket, sliding window, and fixed window algorithms with Redis for distributed rate limiting.
Rate limiting is essential for API security and stability.
Token Bucket Algorithm
Flexible rate limiting that allows bursts while maintaining average limits.
Sliding Window
Smooth rate limiting without the boundary issues of fixed windows.
Fixed Window
Simplest to implement but can allow double the rate at window boundaries.
Redis-Based Rate Limiting
Use Redis for distributed rate limiting across multiple server instances.
Best Practices
- ●Return 429 status with Retry-After header
- ●Rate limit by API key, IP, or user
- ●Use different limits for different endpoints
