// response.statusMessage APi

// Importing http module
const http = require('http');

// Setting up PORT
const PORT = process.env.PORT || 3000;

// Creating http Server
const httpServer = http.createServer(function (request, response) {
    response.writeHead(200, {
        'Content-Length': Buffer.byteLength("GeeksforGeeks"),
        'Content-Type': 'text/plain'

    const value = response.statusMessage;

    // Display result
    // by using end() api
    response.end("hello World", 'utf8', () => {
        console.log("displaying the result...");


        httpServer.close(() => {
            console.log("server is closed")
        })
    });

    console.log("status message : " + value)
});

// Listening to http Server
httpServer.listen(PORT, () => {
    console.log("Server is running at port 3000...");
});

Run the index.js file using the below command:

node index.js

Console output:

Server is running at port 3000...
status message : OK
displaying the result...

// Importing http module
const http = require('http');

// Request and response handler
const http2Handlers = (request, response) => {

    response.writeHead(200, {
        'Content-Type': 'text/plain'
    }).end("hello World", 'utf8', () => {
        console.log("displaying the result...");
    });

    // Getting the statusMessage
    // by using statusMessage API
    const value = response.statusMessage;

    httpServer.close(() => {
        console.log("server is closed")
    })

    console.log("status message : " + value)
};

// Creating http Server
const httpServer = http.createServer(
    http2Handlers).listen(3000, () => {
        console.log("Server is running at port 3000...");
    });
