Step 2 – Install Node.js and NPM

After adding required PPA file lets install Nodejs package. NPM will also be installed with node.js. This command will also install many other dependent packages on your system.

sudo apt-get install nodejs

Step 3 – Test Node.js and NPM Version

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 the 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 web server using the command.

node http_server.js

Server running at http://127.0.0.1:3000/

Web server has been started on port 3000. Now access http://127.0.0.1:3000/ url in browser.
