Thanks you for the suggestions, will look into it! I need a Redis database for this? I actually want a solution without using any database - I was thinking of using a global._ variable that is used to store the IPs

built something like this and tested with a limit of 2requests every 2seconds and seems like it works

im back just to say that i found a way cleaner way to do it with this package https://www.npmjs.com/package/lambda-rate-limiter

npm

lambda-rate-limiter

Simple in-memory rate-limit for Node.. Latest version: 3.0.1, last published: a year ago. Start using lambda-rate-limiter in your project by running npm i lambda-rate-limiter. There are 5 other projects in the npm registry using lambda-rate-limiter.

(since i use vercel, lambda is my way to go) and my code is now looking like this

const ip = evt.request.headers.get("x-real-ip") || evt.request.headers.get("x-forwarded-for") || "127.0.0.1";
    const limit_count = 30;

    if (!global._rate_limiter) (
      global._rate_limiter = rate_limiter({
        interval: 1000 * 2, // 2 seconds.
        uniqueTokenPerInterval: 500
      })
    );

    try {
      await global._rate_limiter.check(limit_count, ip);
    }
    catch (count) {
      return json({
        success: false,
        code: ResponseErrorCode.RateLimit,
        debug: {
          current_count: count,
          limit_count
        }
      }, { status: 429 });
    }

const ip = evt.request.headers.get("x-real-ip") || evt.request.headers.get("x-forwarded-for") || "127.0.0.1";
    const limit_count = 30;

    if (!global._rate_limiter) (
      global._rate_limiter = rate_limiter({
        interval: 1000 * 2, // 2 seconds.
        uniqueTokenPerInterval: 500
      })
    );

    try {
      await global._rate_limiter.check(limit_count, ip);
    }
    catch (count) {
      return json({
        success: false,
        code: ResponseErrorCode.RateLimit,
        debug: {
          current_count: count,
          limit_count
        }
      }, { status: 429 });
    }
