Example 1: Filename: index.js

Javascript

// Node.js program to demonstrate the
// request.socket property

// 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) {

        // Getting proxy socket
        // by using request.socket
        const value = request.socket;

        // Display result
        response.end(value.remoteFamily, 'utf8', () => {
            console.log("Writing remotefamily of socket...");

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

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

Run the index.js file using the following command:

node index.js

Output:

Server is running at port 3000...

Now open your browser and go to http://localhost:3000/, you will see the following output on your screen:

IPv6

Now close the browser and you will see the following output on your terminal screen:

Server is running at port 3000...
Writing remotefamily of socket...
server is closed

Example 2: Filename: index.js

Javascript

// Node.js program to demonstrate the
// request.socket property

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

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

    // Getting proxy socket
    // by using request.socket method
    const value = request.socket;

    // Display result
    response.end(value.remoteFamily, 'utf8', () => {
        console.log("Writing remotefamily of socket...");

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

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

Run the index.js file using the following command:

node index.js

Output:

Server is running at port 3000...

Now open your browser and go to http://localhost:3000/, you will see the following output on your screen:

IPv6

Now close the browser and you will see the following output on your terminal screen:

Server is running at port 3000...
Writing remotefamily of socket...
server is closed
