A lightweight Node.js library that automates Riot Games API rate‑limiting. It wraps node‑fetch and uses Bottleneck (with optional Redis clustering) to enforce per‑region and per‑method limits, auto‑retries 429 responses, supports request prioritisation and concurrency, and provides helpers for building Riot API URLs—ideal for developers building bots, stats tools, or any service that calls Riot’s public endpoints.
