Installing Node.js 14 on CentOS 8 & RHEL 8

An setup script is available which eases the installation of Node.js 14 on CentOS 8 & RHEL 8. You don’t need to build binaries from source code. The process is as simple as pulling the script and executing it, then run yum install commands.
The script will import RPM GPG key for the repository and create a repository file for Node.js packages.

$ sudo yum -y install curl
$ curl -sL https://rpm.nodesource.com/setup_14.x | sudo bash -

Example output:

Conclusions

Node.js is a runtime based on the V8 Javascript engine made by google, and originally used in the Chrome browser. By using it we can create applications using Javascript outside the context of a web browser. In this tutorial we saw how to install the nodejs package on RHEL/CentOS Linux 8 Operating system.
