telegraf-ratelimit

Rate-limiting middleware for the Telegraf Telegram bot framework (v2.0.0). Simple in-memory rate limiter with configurable time window, request limit, custom key generation, and exceeded-limit callback. Lightweight, no external dependencies, designed for ease of integration with Telegraf. Suitable for basic bot rate limiting but not distributed or persistent (in-memory only). Actively maintained as part of the Telegraf ecosystem.
