Abstract
The Intelligent API Gateway is a specialized middleware system designed to secure and manage high volume API traffic in enterprise environments. Built on the MERN stack (MongoDB, Express.js, React, Node.js) with Redis integration, the system provides a centralized control plane that enhances security, reliability, and scalability. Its core innovation lies in combining essential gateway functions — request routing, authentication, and logging — with advanced capabilities including real-time abuse detection, dynamic rate limiting using Token Bucket and Sliding Window algorithms, JWT-based stateless authentication, and an interactive React-based admin dashboard. Data collection and preprocessing pipelines ensure that only valid, authenticated, and non-excessive API traffic is forwarded to backend services. Static code analysis using ESLint is incorporated to maintain code quality and reduce runtime vulnerabilities.
