In this post, we will get to know and learn about running multiple node js version on the same machine with NVM .
While working on the multiple projects of NodeJs, you might be required to run different projects on the different nodejs version or for the legacy nodejs projects, you might require an old version of the nodejs, and the others required a new version of node-js, or to checkout the new feature of nodejs, you need to install the latest version of node js
As on the same machine, we can only install one version of the nodejs, so it's very painful to uninstall and install the new node version as per your project requirements.
To overcome this problem, we can use the Node Version Manager (NVM). NVM allows installing multiple node js versions on the same machine and switching between the required node js version.
Installation of NVM
Windows

Usage
Get a List of all available NodeJs versions
nvm ls available
//windows
nvm ls-remote
//MacOs/Linux
Install latest NodeJs version
nvm install node
Install latest LTS Release
nvm install --lts
Install particular NodeJs version
Multiple NodeJs version can be installed using the below command.
nvm install 8.11.1
// to install the 8.11.1 version
UnInstall the multiple NodeJs version
nvm uninstall 8.11.1
Switching the NodeJs version
nvm list
//for windows
nvm ls
//for MacOs/linux
Switching Between installed NodeJs Versions
nvm use 8.11.1
//To enable 8.11.1
nvm use 12.13.1
