Rate Limit Mongo Store

rate-limit-mongo is a specialized MongoDB store designed for the popular `express-rate-limit` middleware, currently at version 2.3.2. This package provides a persistent, database-backed storage mechanism for rate limiting records, moving beyond in-memory or Redis solutions. It leverages MongoDB's TTL (Time-To-Live) indexes to automatically expire rate limiting entries, ensuring efficient cleanup and preventing stale data. While not on a strict release cadence, updates typically align with bug fixes or `express-rate-limit`/MongoDB driver compatibility improvements. Its primary differentiation lies in offering a robust, low-configuration MongoDB-specific solution for managing API rate limits, particularly beneficial for applications already using MongoDB and requiring shared, persistent rate limit counters across multiple instances.
