Overview

Book Description: High-Performance Node.js Scripting Unlock the full potential of Node.js for building ultra-fast, resilient API Gateways and backend services. Conquer Performance Bottlenecks Move beyond basic Node.js tutorials and dive deep into high-performance scripting. This book is your essential guide to mastering the techniques that separate efficient, production-ready systems from slow, scaling failures. Learn to diagnose and eliminate performance bottlenecks stemming from inefficient I/O operations and inadequate concurrency management. Deep Dive into I/O and Concurrency You'll explore advanced concepts and practical strategies for: Optimizing I/O-Bound Operations: Understand the nuances of Node.js's event loop and asynchronous nature. Learn to leverage streams, buffers, and native C++ add-ons to maximize throughput for disk and network I/O. Harnessing Modern Concurrency: Master the use of Worker Threads and Clusters to utilize multi-core processors effectively, ensuring your gateway remains responsive even under heavy load. Advanced Resource Management: Implement intelligent caching, connection pooling, and backpressure mechanisms to protect your gateway from resource exhaustion and ensure predictable latency. Build Scalable API Gateways Specifically tailored for developers working on modern API Gateways, this book provides real-world patterns and examples for creating a performant core. Learn to script a gateway that can efficiently handle routing, authentication, request transformation, and rate limiting at scale. If you're a developer, architect, or DevOps engineer looking to elevate your Node.js applications-especially in a microservices or high-traffic environment-to world-class performance, this is the definitive resource you need.
