Setting Up NodeJS with NVM on Centos 7

Centos 7 offers NodeJS and NPM via yum install. While this is great, it's not optimal because it pins users to the version offered via yum. Moreover, a yum update can easily upgrade the NodeJS version leading to all kinds of breaking. Not what we want.

Luckily, nvm can help us.

In the same vain as rbenv, rvm or plenv: this is a version manager that leaves the "system" node installation alone and allows you to install and manage different versions of nodejs and npm concurrently.
