When you need to respect rate limits, back off on 429s, or run a percentage rollout, these packages handle the arithmetic so you do not have to ship a heavier dependency for it.
exchequerv0.1.0Minimal async token-bucket rate limiter , refill R/sec, burst B, await for capacity. Zero deps, isomorphic, injectable clock.
forbearv0.1.4Read the server's rate-limit instructions , turn a 429/503 Response into the number of milliseconds to wait, with correct fallback backoff.
stanchv0.1.1Suppress repeated events by key within a time window while counting what you dropped , kill log floods and alert flapping.
sortitionv0.1.5Deterministic percentage rollouts and A/B bucketing , sticky, monotonic, dependency-free, identical in every runtime.
