Getting Started with Express

To get started, let's go ahead and add Express.js to our project by running the following command:

npm install express --save

Installing the Express 4.0 Application Generator

We want to be able to generate applications in the same way that Ruby on Rails can. We're going to run a command to install an Express.js application generator:

sudo npm install -g express-generator

We'll touch more on this later.

Make sure we're all set

We're going to run a few commands to make sure we have the required dependencies for our application:

node --version    #checks node version
npm --version     #checks npm version
express --version #checks express version
