Node Fundamentals – Part 1

In this chapter, you'll learn a ton about building Node applications, and you'll actually build your first Node application. This is where all the really fun stuff is going to start.

We'll kick things off by learning about all of the modules that come built in to Node. These are objects and functions that let you do stuff with JavaScript you've never been able to do before. We'll learn how to do things, such as reading and writing from the filesystem, which we'll use in the Node's application to persist our data.

We'll also be looking at third-party npm modules; this is a big part of the reason that Node became so popular. The npm modules give you a great collection of third-party libraries you can use, and they also have really common problems. So you don't have to rewrite that boilerplate code over and over again. We'll be using a third-party module in this chapter to help with fetching input from the user.

The chapter will specifically cover the following topics:

• Module basics
• Require own files
• Third-party modules
• Global modules
• Getting input
