Wexler J. Node.js Projects. Building Real-World Web Apps and Backend APIs 2025

Textbook in PDF format Whether you're a JavaScript beginner ready to build your first backend app or a self-taught developer looking to grow beyond tutorials, Node.js Projects gives you the hands-on experience you need. Through a series of self-contained projects ranging from CSV generators and content aggregators to secure password managers, web scrapers, and an AI-powered learning assistant, you'll apply modern tools like Fastify, MongoDB, Redis, JWT, and Google's Gemini API in practical, job-relevant ways. With each chapter, author Jon Wexler challenges you to think like an engineer, emphasizing architectural thinking, clean coding, and iterative design. You'll build confidence solving real-world problems while deepening your understanding of asynchronous programming, API design, security practices, and scalable deployment patterns. Node.js Projects is crafted to showcase these new techniques and empower you to grow as a developer by focusing on five key principles: a practical learning approach, modular learning, diverse use cases, incremental skill building, and immediate feedback and gratification. Each project is designed to provide hands-on, real-world experience, enabling you to apply Node.js in modular, digestible steps. This approach not only supports gradual skill development but also ensures that each chapter delivers a satisfying sense of accomplishment, reinforcing your growth as you progress through varied and increasingly challenging applications. Programming newcomers quickly grasp how to piece together an application, but building an app is more than code—it’s about understanding architecture and design. Each chapter places you in the role of an engineer making real-world decisions. I believe practical experience isn’t copying and pasting code but developing the mindset, problem-solving skills, and communication required to build products with impact. The scope of software challenges varies: some projects unfold over months, while others involve quick, focused problem-solving. This book provides a balance, offering both bite-sized coding exercises and larger, more complex projects. This modular structure encourages you to complete sections at your own pace, allowing you to pause, shift focus, or dive into chapters that align with your interests and skill level. JavaScript, and by extension Node.js, has experienced incredible growth over the past 15 years. This evolution has allowed Node.js to become a go-to tool for creating everything from high-performance web apps to real-time notification systems and video streaming platforms. Learning Node.js today means understanding a wide range of potential applications. Each chapter offers you not only technical skills but a mindset for approaching real-world scenarios you’re likely to encounter on the job. This way, you’ll develop the versatility to apply Node.js to diverse projects, enhancing both your confidence and your adaptability. Confidently master async programming with async/await, Promises, and the Node.js event loop Effectively design scalable APIs using Fastify and modular routing patterns Reliably manage data with the filesystem, MongoDB, and CSV output Securely implement authentication flows with JWTs and environment-based configs Seamlessly integrate third-party APIs like OpenAI and Google Gemini Efficiently build real-time features with Redis, schedulers, and event-driven logic Strategically break down complex problems into modular, testable components Smoothly transition from prototype to production with modern Node.js workflows
