Node.js Web Development - Third 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. 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.

Installing from source on POSIX-like systems

Installing the prepackaged Node.js distributions is currently the preferred installation method. However, installing Node.js from source is desirable in a few situations:

  • It can let you optimize the compiler settings as desired

  • It can let you cross-compile, say, for an embedded ARM system

  • You might need to keep multiple Node.js builds for testing

  • You might be working on Node.js itself

Now that you have the high-level view, let's get our hands dirty mucking around in some build scripts. The general process follows the usual configure, make, and make install routine that you may already have performed with other open source software packages. If not, don't worry, we'll guide you through the process.

Note

The official installation instructions are in the README contained within the source distribution at https://github.com/nodejs/node/blob/master/README.md.

Installing prerequisites

As noted in the preceding section, there are three prerequisites: a C compiler...
