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. Node.js Web Development shows JavaScript is not just for browser-side applications. It can be used for server-side web application development, real-time applications, microservices, and much more. 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 and maintain your own Node.js application. 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 much more.

The easiest way to verify that your Node.js installation works is also the best way to get help with Node.js. Type the following command:

$ node --help
Usage: node [options] [ -e script | script.js ] [arguments] 
       node debug script.js [arguments] 

Options:
  -v, --version         print Node.js version
  -e, --eval script     evaluate script
  -p, --print           evaluate script and print result
  -c, --check           syntax check script without executing
  -i, --interactive     always enter the REPL even if stdin
