This comprehensive guide begins by introducing the core principles of Node.js, covering installation, environment setup, and modular programming. Readers then build foundational skills by creating their first applications and exploring essential web technologies like HTTP and popular frameworks such as Express and Nest. The journey continues into advanced topics like template engines, database integration, and authentication techniques, equipping readers to build full-featured web applications.
As readers progress, the book delves into building RESTful and GraphQL APIs, real-time applications with WebSockets, and writing type-safe Node.js code using TypeScript. Later chapters explore command-line tools, asynchronous programming with Promises and RxJS, streams, and file handling. Comprehensive sections on package management, quality assurance, testing, and security provide practical insights to produce robust, maintainable software.
The final chapters focus on deploying scalable applications, performance optimization, microservices architecture, and introduce the emerging Deno runtime. Throughout the book, detailed examples and step-by-step explanations guide readers from fundamental concepts to advanced techniques, making this an essential resource for developers seeking mastery of server-side JavaScript development with Node.js.
