Rate-Limiter-Lib

Simple event-based rate limiting that can used by your server or my schildwall-gateway as middleware. It stops the dripper when to requests are in the queue and restarts when a new entity is pushed.

It will run until all requests are answered and only then stop running!

Leaky Bucket Limiter

import {LeakyBucketRateLimiter} from '@vampyreio/ratelimiter-lib';

const rateLimiter = new LeakyBucketRateLimiter({
    quanitityOfDrips: 1,
    timeBetweenDrips: 100,
});

async () => {
    // test rate limits that are not taken care of
    this.rateLimiter.wait();
    this.rateLimiter.wait();
    this.rateLimiter.wait();

    // resolves when the rate limiter lets it pass through
    const start = Date.now();
    return await this.rateLimiter.wait();
    const stop = Date.now();
}();

Options
