Node.js is a powerful tool for controlling web servers, building applications, and creating event-driven programming. And it brings JavaScript—a language familiar to all web developers—into an environment independent of web browsers. Learn all about Node.js and start creating JavaScript applications in this course with Joseph LeBlanc. He shows how to install Node.js on Mac, Windows, and Linux and dives deep into its modules and Express framework for app development. Learn how to unit test your code, start sessions on web servers, stream data, and create simple command-line tools.

Topics include:
  • Why use Node.js?
  • Installing Node.js
  • Understanding the event loop
  • Initializing Node.js projects
  • Creating modules with getters and setters
  • Starting Express applications
  • Testing your code
  • Working with sessions and databases
  • Building command-line tools
  • Emitting events and attaching listeners

Initializing Node.js projects

The best way to start a project in Node is to create a package.jason file. In this video we'll use the npm command to generate this file for us. First let's create a folder for this project. I'm going to create it on the desktop and name it airline. Now go to terminal. Type in cd and space, and now drag the folder into terminal to get the path. Now type return. Now I'm going to use a tool called npm. Npm is distributed with node and it helps with module installation, among other things Right now we're going to use npm to help us generate a package.json file.

To do that type npm and it. After you press enter, it'll step you through the creation of the file. The first thing it prompts you for is the name, and if you don't specify a name, it'll just use the name of the folder where the package.json file is going to be. In this case it's airline, and that's fine with me. So I'm going to hit return. Next it's going to ask you for a version. In this case, I'm just going to accept the default because I don't care. Next, it's going to ask for description of the project. Let's type in a small description.

After the description, it's going to prompt for an entry point. Every project that you create in Node is going to have an entry point. And in this case I'm just going to accept the default of index.js. Now it's going to prompt for a test command. Later on, we can set this up to automatically run unit tests. But at the moment, we're just going to leave this blank. After test, it allows us to supply the path to a git repository. This is useful if you're distributing your project to someone else, but in this case we're just building it for ourself.

So leave git repository blank. Next there are keywords. Again, this is if you're distributing the project elsewhere, so leave it blank. Now it's prompting for an author. In this case, I'm going to type in my name, and then I'm going to supply my email address in angle brackets. After author, it's going to prompt for a license. You can add any license you like here. And, in this case, I'm just going to accept the default. After answering all of the questions, it's going to show you a preview of the package.json file. If everything is okay, you can just type return.

Now, when we list the contents of the folder, there's a package.json file. I'm going to open it up in SublimeText. The package.json file identifies a project, who authored it, and which file is the entry point. This file will also keep track of the modules this project depends on. In the next video, we'll use this package.json file to keep track of the community-provided modules as we're installing them.
