Step 4 – Create Demo on Web Server

If you want to check and verify your node.js installed. Let’s create a web server with “Hello World” text.
Creating a file with name test_server.js like below:-

# vim test_server.js

After creating a file adding the some 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/');

After that we should save the file and run below commands to start the server.

node  test_server.js

You should see an output that reads:

debugger listening on port 5858
Server running at http://127.0.0.1:3000/

You can also start the application with debugging through below commands.

$ node --inspect server.js


Debugger listening on ws://127.0.0.1:9229/938cf97a-a9e6-4672-922d-a22479ce4e29
For help, see: https://nodejs.org/en/docs/inspector
Server running at http://127.0.0.1:3000/

 

Now we can open the browser and type server hostname or IP address followed by port number 3000 like below:-

http://localhost:3000

then we will see a default page with Hello World.
