Rate Limiter

A flexible, lightweight rate limiting utility designed to control the number of times a function can be executed within a specific time window. This is especially useful for API calls or any operation that requires throttling to prevent overuse.

Features

• Simple configuration for limiting API or function calls.
• Supports both synchronous and asynchronous operations.
• Easily customizable rate limits for different APIs or functions.
• Keeps track of call counts and automatically resets after a time window.

Installation

Install via NPM:

npm install rate-limiter-advance

yarn add rate-limiter-advance

Example

const RateLimiter = require('rate-limiter');

const rateLimiter = new RateLimiter();

// Configure rate limit: Allow 5 calls every 60 seconds rateLimiter.addConfig('getUserData', 5, 60);

const getUserData = () => { console.log('API call to get user data executed'); };

const callApi = () => { rateLimiter.execute('getUserData', getUserData); };

// Simulate multiple API calls for (let i = 0; i < 10; i++) { callApi(); }
