    Add Nodejs Package on Server

    We are going to add the latest package on server so that we can install latest nodejs

    sudo apt-get install curl
    curl -sL https://deb.nodesource.com/setup_12.x | sudo -E bash -

    Install Node.js on Ubuntu

    sudo apt-get install nodejs

    Check Node.js Version on server

    node -v 
    
    v12.8.0

    Check NPM Version on server

    npm -v 
    
    6.10.2

    Node and NPm is installed sucessfully !! Now we are going to create demo node js server

    vim server.js

    After creating a file, please add the following content :

    var http = require('http');
    http.createServer(function (req, res) {
    res.writeHead(200, {'Content-Type': 'text/plain'});
    res.end('Hello Node Server\n');
    }).listen(5000, "127.0.0.1");
    console.log('Server running at http://127.0.0.1:5000/');

    Please start the Node application using following command:

    node server.js

    After that you will see the output

    debugger listening on port 5858
    Server running at http://127.0.0.1:5000/

    Note : if you want to set node js on public ip of server you can repalce the ip 127.0.0.1 to your server ip . Also need to open the define port in server firewall.
