Node.js in Practice: Building APIs, Databases, and Real-Time Applications is a practical guide to modern backend development with Node.js.Starting with the foundations of Node.js and JavaScript, this book gradually introduces the concepts, tools, and development techniques used to create modern server-side applications. The chapters progress from the Node.js runtime and core modules to APIs, databases, authentication, security, testing, and real-time communication.The book covers: Node.js fundamentals and application architectureModern JavaScript concepts for backend developmentCore Node.js modules and npmAsynchronous programming and event-driven applicationsHTTP servers and REST APIsExpress.js, routing, and middlewarePostgreSQL and database-driven applicationsAuthentication and authorizationJWT-based security and API protectionFile systems and streamsTesting, debugging, logging, and error handlingWebSockets and Socket.IOReal-time communication and messagingRooms, namespaces, and private communicationApplication performance and scalabilityThroughout the book, practical examples and complete code samples demonstrate how these concepts can be combined to create functional backend applications. Database integration, secure authentication, API development, file processing, testing, and real-time features are presented as part of a connected development workflow.Node.js in Practice is suitable for programmers, developers, students, software engineers, and technology professionals looking for a practical reference to Node.js application development.From the fundamentals of the Node.js runtime to database-backed APIs and real-time applications, this book provides a structured foundation for developing modern backend systems with Node.js.
