Book Description

Node.js underpins much of modern web development, powering everything from APIs to full-stack applications. Authors Mario Casciaro, whose emergency management software is used in over 37 countries, and Luciano Mammino, an AWS Serverless Hero, Microsoft MVP, and international speaker, offer a thoughtful look at the platform to help you to put Node in context. This comprehensive guide uncovers what goes on under the hood and allows you to make the most of the JavaScript language and the Node runtime, making it a reliable reference for newer and more experienced developers alike. Building on the highly rated third edition, this new edition features fresh case studies and the latest Node.js developments, including the adoption of newer APIs and libraries, Web Streams, improvements in ESM modules, and tips on using Node with TypeScript. What’s more, this fourth edition brings a brand-new chapter on testing. Real-world examples throughout the book demonstrate Node.js in action with technologies such as Redis, RabbitMQ, LevelDB, and ZeroMQ, while end-of-chapter exercises consolidate your understanding. By the end of this Node.js book, you'll have mastered Node.js design patterns to architect robust, efficient, and maintainable applications confidently.
