API Rate Limiting - Complete Implementation Guide |…

Protecting APIs from Abuse and Ensuring Fair Usage

API rate limiting is a technique used to control the number of requests a client can make to an API within a specific time period. It protects APIs from abuse, ensures fair resource usage, prevents system overload, and enables monetization through different pricing tiers.

What is Rate Limiting?

if (count >= limit) {

This section demonstrates a simplified example of rate limiting logic. It checks if the number of requests exceeds the defined limit.

return { allowed: false, remaining: 0 };

// Process the request

This section outlines the process of handling a request and applying rate limiting rules. The `handleRequest` function is responsible for processing individual requests.
