Installing Node.js on Rocky Linux 8

Hello,

In this week’s feature highlight, we look at How to Install Node.js on Rocky Linux 8

Node.js is a JavaScript runtime environment and it is primarily used for non-blocking, event-driven servers, due to its single-threaded nature. It’s used for traditional websites and back-end API services but was designed with real-time, push-based architectures. It offers users the ability to write websites in JavaScript whose code executes on the server instead of a client’s browser.

First, check for the update to keep the server up to date.

yum update -y
