Rate limiting manages your network’s traffic and limits the number of times someone repeats an operation in a given duration, such as using an API. A service without a layer of security against rate limit abuse is prone to overload and hampers your application’s proper operation for legitimate customers.
In this tutorial, you will build a Node.js server that will check the IP address of the request and also calculate the rate of these requests by comparing the timestamp of requests per user. If an IP address crosses the limit you have set for the application, you will call Cloudflare’s API and add the IP address to a list. You will then configure a Cloudflare Firewall Rule that will ban all requests with IP addresses in the list.
By the end of this tutorial, you will have built a Node.js project deployed on DigitalOcean’s App Platform that protects a Cloudflare routed domain with rate limiting.
