Build Scalable, Secure, and High-Performance APIs with Express Gateway, Rate Limiting & Monitoring

What you'll learn

Understand the Role of an API Gateway – Learn why API Gateways are essential in modern architectures and how they help manage microservices efficiently.

mplement Request Routing with Express Gateway – Set up and configure Express Gateway to route API requests dynamically.

Apply Rate Limiting for API Security – Protect APIs from abuse by implementing rate limiting strategies to control incoming traffic.

Monitor and Log API Requests – Gain insights into API usage, detect issues, and track performance using logging and monitoring tools.

Secure APIs with Authentication & Authorization – Implement authentication mechanisms such as API keys, JWT, and OAuth for API security.

Optimize API Performance & Scalability – Learn best practices to enhance API performance and ensure smooth handling of high traffic loads.

Requirements

Basic Knowledge of Node.js – Understanding of jаvascript and Node.js fundamentals.

Familiarity with Express.js – Basic experience with building APIs using Express.js (helpful but not mandatory).

Understanding of REST APIs – Basic knowledge of how APIs work and how clients interact with them.

A Computer with Internet Access – Any system (Windows, macOS, or Linux) capable of running Node.js.

Node.js & npm Installed – We'll guide you on how to set this up if you haven't already.

Description
