Node JS Programming (A Complete Guide to Node.js, JavaScript, NPM, Express.js, REST APIs, MongoDB, Authentication, and Real-World Backend Development)

Node JS Programming is a practical and comprehensive guide designed to help students, beginners, and aspiring backend developers learn how to build powerful, scalable, and modern server-side applications using Node.js.

The book begins with the fundamentals of Node.js and JavaScript and gradually progresses to advanced backend development concepts. You will learn how Node.js works, how to manage packages with NPM, create web servers, develop REST APIs using Express.js, connect applications with databases, implement authentication and authorization, handle files, and build complete backend applications.

The book emphasizes practical programming, real-world development techniques, API development, database integration, security, testing, and deployment. It also provides the foundation required for working with modern technologies such as the MERN Stack.
