@dealerslink/node-express-rate-limiter

node-express-rate-limit is a cache-based, request reate limiter for use with expressJS. It is designed for use with request-utils but can be used without. It caches a store of IP address, Method, and Request tuples used to make any request and then temporarily blocks requests from those sources once a limit for those requests have been exceeded.

npm install @dealerslink/express-rate-limiter

const RateLimiter = require('@dealerslink/node-express-rate-limiter');
rateLimiter = new RateLimiter('rateLimit');
