Simulate a leaky bucket to understand how many calls and requests can be made in a certain amount of time without going beyond capacity.

leaky-bucket-simulator.js

let callCount = 0;
let bucketCount = 0;

// Bucket Settings
const bucketCapacity = 8;
const leakRate = 2;
const leakTime = 1000;

// Call Settings
const callAmount = 5;
const timePerCall = 2000;
const requestsPerCall = 4;

// Bucket Interval - Controls how full the bucket is and leaks a certain amount per second.
const bucketInterval = setInterval(() => {
  console.log(`Bucket Count: ${bucketCount} Call Count: ${callCount}`);
  if (bucketCount > 0) {
    bucketCount -= leakRate;
  }
  if (bucketCount >= bucketCapacity) {
    console.error("Bucket is full.");
  }
  if (callCount === callAmount) {
    clearInterval(bucketInterval);
    clearInterval(callInterval);
    res.status(200).send();
  }
}, leakTime);

// Call Interval - Controls the amount of requests filling the bucket in a given time.
const callInterval = setInterval(() => {
  callCount += 1;
  bucketCount += requestsPerCall;
}, timePerCall);
