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.

Did you notice earlier when we said run the Notes application stack? It's time to explain to the marketing team what's meant by that phrase. They'll perhaps need to put an architecture diagram on marketing brochures and the like. It's also useful for developers like us to take a step back and draw a picture of what we've created, or are planning to create. 

Here's the sort of diagram that an engineer might draw to show the marketing team the system design. The marketing team will, of course, hire a graphics artist to clean it up:

The box labeled Notes Application is the public-facing code implemented by the templates and the router modules. As currently configured, it's visible from our laptop on port 3000. It can use one of several data storage services. It communicates with the backend User Authentication Service over port 3333 (as currently configured).

In Chapter 10, Deploying Node.js Applications, we'll be expanding this picture a bit as we learn how to deploy...
