NodeJs Configuration

NodeJs configuration for Rocket.Chat
Welcome to the Node.js configuration guide for Rocket.Chat, a comprehensive resource designed to help you understand the intricacies of setting up and configuring Rocket.Chat's environment using Node.js. Rocket.Chat is built on top of Node.js, which is the engine that powers its functionality. This guide provides a brief overview of some of the details of Node.js, with a more detailed guide available in the official Node.js documentation.
Rocket.Chat is built with  Meteor, a JavaScript framework, and the version of Meteor in use dictates the supported Node.js version for that specific version. The guide provides instructions on how to check the supported Node.js version for any specific release by navigating to the GitHub releases page for that specific version.
The only reason you may need to check this (except for idle curiosity or debugging purposes) is if you're using the manual method of deployment. We don't recommend manual installation. Instead, Docker is recommended and encouraged. With Docker (or Snap) you won't need to worry about the Node version.
