How to install Node.js on CentOS / Red Hat / Fedora

Node.js is not available in the default CentOS / Red Hat package repository but in EPEL (Extra Packages for Enterprise Linux) repository. Even so, it's still a slightly outdated version of Node.js.

1. Enable epel-release repository by installing the epel-release package.

   $ sudo yum install --assumeyes epel-release

2. Install nodejs package. This will also install npm as dependency.

   $ sudo yum install --assumeyes nodejs
