koa2-ratelimit

IP rate-limiting middleware for Koa2, inspired by express-rate-limit. Version 1.1.3 supports Redis, MongoDB (via Mongoose), and Sequelize stores. Release cadence is low; last significant update was in 2020. Differentiators: async/await, flexible interval config (ms or object), per-route keys, and delay-after behavior for throttling. Requires Node >=7.10 and peer deps for advanced stores.
