Node.js Web Development - Fourth Edition

By: David Herron

Overview of this book

Node.js is a server-side JavaScript platform using an event-driven, non-blocking I/O model allowing users to build fast and scalable data-intensive applications running in real time. This book gives you an excellent starting point, bringing you straight to the heart of developing web applications with Node.js. You will progress from a rudimentary knowledge of JavaScript and server-side development to being able to create, maintain, deploy and test your own Node.js application.You will understand the importance of transitioning to functions that return Promise objects, and the difference between fs, fs/promises and fs-extra. With this book you'll learn how to use the HTTP Server and Client objects, data storage with both SQL and MongoDB databases, real-time applications with Socket.IO, mobile-first theming with Bootstrap, microservice deployment with Docker, authenticating against third-party services using OAuth, and use some well known tools to beef up security of Express 4.16 applications.

Mobile-first paradigm

Mobile devices have a smaller screen, are generally touch oriented, and have different user experience expectations than a desktop computer.

To accommodate smaller screens, we use responsive web design techniques. This means designing the application to accommodate the screen size and ensuring websites provide optimal viewing and interaction across a wide range of devices. Techniques include changing font sizes, rearranging elements on the screen, using collapsible elements that open when touched, and resizing images or videos to fit available space. This is called responsive because the application responds to device characteristics by making these changes.

By mobile-first, we mean that you design the application first to work well on a mobile device and then move on to devices with larger screens. It's about prioritizing mobile...
