Node.js is an open source server environment. Node.js allows you to run JavaScript on the server.
There are different method you can use to install and setup node.js on centos operating system.
In this session we are going to see how to intall Node.js using NVM.
To install NVM on Centos machin, visit the project’s GitHub page. You can use below command to download its installer bash script, which will install the nvm script for current logged in user.
[root@siddhesh ~]# curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.35.3/install.sh | bash

=> Compressing and cleaning up git repository
=> Appending nvm source string to /root/.bashrc
=> Appending bash_completion source string to /root/.bashrc
=> Close and reopen your terminal to start using nvm or run the following to use it now:
export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh" # This loads nvm
[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion" # This loads nvm bash_completion
[root@siddhesh ~]#
Then source current user bash profile to start using installed NVM environment.
[root@siddhesh ~]# source ~/.bash_profile
[root@siddhesh ~]#
Now lets see list of available version of Node.js using NVM.
[root@siddhesh ~]# nvm list-remote

Now using node v13.2.0 (npm v6.13.1)
Creating default alias: default -> v13.2.0
[root@siddhesh ~]#
To verify installed version of Node.js and its alias status run below command.
[root@siddhesh ~]# nvm list

[root@siddhesh ~]#
Here you can see that (N/A) its release base aliases are not available on the current machin.
To get this install run the following nvm command.
[root@siddhesh ~]# nvm install lts/argon
