Web Development with Node and Express

Chapter 2. Getting Started with Node

If you don’t have any experience with Node, this chapter is for you. Understanding Express and its usefulness requires a basic understanding of Node. If you already have experience building web apps with Node, feel free to skip this chapter. In this chapter, we will be building a very minimal web server with Node; in the next chapter, we will see how to do the same thing with Express.

Getting Node

Getting Node installed on your system couldn’t be easier. The Node team has gone to great lengths to make sure the installation process is simple and straightforward on all major platforms.

The installation is so simple, as a matter of fact, that it can be summed up in three simple steps:

1. Go to the Node home page.
2. Click the big green button that says INSTALL.
3. Follow instructions.

For Windows and OS X, an installer will be downloaded that walks you through the process. For Linux, you will probably be up and running more quickly if you use a package manager.

Caution

If you’re a Linux user and you do want to use a package manager, make sure you follow the instructions in the aforementioned web page. Many Linux distributions will install an extremely old version of Node if you don’t add the appropriate package repository.

You can also download a standalone installer, which can be helpful if you are distributing Node to your organization.
