Step 4 – Create A 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 webserver 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.
