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.

Flexbox and CSS Grids


Other new technologies impacting web application development are two new CSS layout methodologies. The CSS3 committee has been working on several fronts, including page layout. 

In the distant past, we used nested HTML tables for page layout. That is a bad memory that we don't have to revisit. More recently, we've been using a box model using DIVs, and even at times using absolute or relative placement techniques. All these techniques have been suboptimal in several ways, some more than others.

One popular layout technique is to divide the horizontal space into columns and assign a certain number of columns to each thing on the page. With some frameworks, we can even have nested DIVs, each with their own set of columns. Bootstrap 3, and other modern frameworks, used that layout technique. 

The two new CSS layout methodologies, Flexbox (https://en.wikipedia.org/wiki/CSS_flex-box_layout) and CSS Grids (https://developer.mozilla.org/en-US/docs/Web/CSS/CSS_Grid_Layout), are...
