Chapter 13. Creating JavaScript Packages

So far we have built up a web application, making use of various npm packages along the way. These packages include libraries such as Express and command-line tools such as Gulp. Now we'll look at how to go about creating packages of our own.

In this chapter we will:

• Explore the different module systems available for JavaScript
• Create our own JavaScript library
• Write JavaScript that can run on both the client and server-side
• Create a command-line tool in JavaScript
• Release a new npm package
• Use Node.js modules in the browser environment

Note

The code examples in this chapter are independent of everything we've done so far.
