| Install Node.js |
New to Node.js ?
Node.js® is a JavaScript runtime built on Chrome's V8 JavaScript engine. Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient. Node.js' package ecosystem, npm, is the largest ecosystem of open source libraries in the world.
More simply put, Node.js allows us to quickly and efficiently run JavaScript code outside the browser, making it possible to use the same language on both the frontend and the backend.
Install the Node.js environment
Node.js will install on most major Operating systems. Mac OS X, Windows and many flavors of Linux are supported.

If you want to install Node.js via pkgsrc:
$ pkgin -y install nodejs

Verify the installation
Before continuing, we need verify that Node.js is correctly installed with the npm package manager.
Print the Node.js version installed on your machine:
$ node -v
v5.7.0
Print the npm version installed on your machine:
$ npm -v
3.6.0
You need to make sure your machine meets the following requirements:
- Node.js >= 4.0.0
- npm >= 3.0.0
