How to install latest version of Node.js for CentOS / Red Hat / Fedora

CentOS and Red Hat does not provide Node.js in its default yum repository, though they still provide slightly outdated version in their epel repository. If you require the latest version of Node.js for your CentOS and Red Hat installation, you'll have to install from NodeSource's Node.js repository.

1. Install curl if it's not already available in your system.

   $ sudo yum install --assumeyes curl

2. Add and enable NodeSource's Node.js repository.

   $ curl --silent --location https://rpm.nodesource.com/setup_10.x | sudo bash -

   Replace 10.x with 12.x, 11.x or 9.x depending on your requirement

3. Install nodejs.

   $ sudo yum install --assumeyes nodejs
