Creating node.js hello world
Open Notepad and paste the below code to run the Node application.
var http = require("http");
http.createServer(function (request, response) {
// Send the HTTP header
// HTTP Status: 200 : OK
// Content Type: text/plain
response.writeHead(200, {'Content-Type': 'text/plain'});
// Send the response body as "Hello World"
response.end('Hello World from Beetechical\n');
}).listen(8081);
// Console will print the message
console.log('Server running at http://127.0.0.1:8081/');
Save the file with .js extension to run the file on a node server.
Open the command prompt and navigate to the file location by using the cd command.
Once you run the file using node, You should be able to open the application on http://127.0.0.1:8081 or http://localhost:8081.
So, we are able to run our javascript application using a node server.
