Node.js Web Development - Fourth Edition

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.

HTTP Servers and Clients

Now that you've learned about Node.js modules, it's time to put this knowledge to work by building a simple Node.js web application. In this chapter, we'll keep to a simple application, enabling us to explore three different application frameworks for Node.js. In later chapters, we'll build some more complex applications, but before we can walk, we must learn to crawl.

We will cover the following topics in this chapter:

  • EventEmitters
  • Listening to HTTP events and the HTTP Server object
  • HTTP request routing
  • ES2015 template strings
  • Building a simple web application with no frameworks
  • The Express application framework
  • Express middleware functions
  • How to deal with computationally intensive code
  • The HTTP Client object
  • Creating a simple REST service with Express
