Use Current Release: At te last update of this tutorial, Node.js 10.0.0 is the current Node.js release available.
sudo apt-get install curl python-software-properties curl -sL https://deb.nodesource.com/setup_10.x | sudo -E bash -
Use LTS Release : At the last update of this tutorial, Node.js 8.11.1 is the LTS release available.
sudo apt-get install curl python-software-properties curl -sL https://deb.nodesource.com/setup_8.x | sudo -E bash -
For this tutorials, we are using latest current release and added their PPA to my system.
Step 2 – Install Node.js on Ubuntu
You can successfully add Node.js PPA to Ubuntu system. Now execute the below command install Node on and Ubuntu using apt-get. This will also installed NPM with node.js. This command also installs many other dependent packages on your system.
sudo apt-get install nodejs
Step 3 – Test Node.js and NPM Version

node -v v10.0.0
Also, check the npm version
npm -v 6.0.0
Step 4 – Create Demo Web Server (Optional)
This is an optional step. If you want to test your node.js install. Let’s create a web server with “Hello World!” text. Create a file http_server.js
vim http_server.js
and add following content
var http = require('http'); http.createServer(function (req, res) { res.writeHead(200, {'Content-Type': 'text/plain'}); res.end('Hello World\n'); }).listen(3000, "127.0.0.1"); console.log('Server running at http://127.0.0.1:3000/');
Now start the Node application using the command.
node http_server.js debugger listening on port 5858 Server running at http://127.0.0.1:3000/
You can also start the application with debugging enabled with the following commands.
node --inspect http_server.js Debugger listening on ws://127.0.0.1:9229/8976a32b-cf99-457c-85fb-e7288cbadac6 For help see https://nodejs.org/en/docs/inspector Server running at http://127.0.0.1:3000/
The web server has been started on port 3000. Now access http://127.0.0.1:3000/ URL in browser. Now you will need to configure a front-end server for your app.
