Rate Limiter

The Rate Limiter component protects your application from abuse, denial-of-service (DoS) attacks, and brute-force attempts by limiting the frequency of incoming requests from a single IP address.

Installation Guide

npx servercn-cli@latest add rate-limiter

Global Rate Limit

app.ts
import express from "express";
import { rateLimiter } from "./middlewares/rate-limiter";
 
const app = express();

  rateLimiter({
