api-rate-limiting

What problem does it solve?

Mitigate unreliable external API calls by providing robust resilience patterns. It helps teams handle transient failures, throttle traffic, and isolate upstream outages.

Core Features & Use Cases

• Retry logic: Automatically retry transient failures with configurable backoff and jitter.
• Circuit breakers: Prevent cascading failures by opening the circuit when error rates rise, then half-open to test recovery.
• Request deduplication: Debounce in-flight identical requests to reduce unnecessary calls and contention.
• Rate limiting: Enforce token-bucket style limits to protect downstream services and manage throughput.
• Use Case: A service calling multiple external APIs can apply these patterns to improve reliability and maintain stable latency.

Quick Start

Initialize the resilience components in your service and begin using the provided APIs (Fetch with Retry, Circuit Breaker, Rate Limiter, and Batch Queue) to perform GET/POST requests with built-in fault tolerance.
