Third-party modules

You now know two out of the three ways to use require(), and in this section, we'll explore the last way, which is to require a package you've installed from npm. As I mentioned in the first chapter, npm is a big part of what makes Node so fantastic. There is a huge community of developers that have created thousands of packages that already solve some of the most common problems in Node applications. We will be taking advantage of quite a few packages throughout the book.
