Function rateLimitMiddleware

Returns Middleware

A middleware function that limits the number of requests from a client IP.

Example usage:

import { start, router, text, rateLimitMiddleware } from "@pulsar-http/core";

const routes = [
    router.get("/api/users", async () => text("User List")),
];

const middlewares = [
    rateLimitMiddleware({
        windowMs: 60000, // 1 minute
        maxRequests: 10,
    }),
]

start({ routes, middlewares });
Copy

In this example, if a client IP makes more than 10 requests within a 1-minute window, subsequent requests will receive a 429 response until the window resets.
