Example 1: Filename: index.js
// Node.js program to demonstrate the // response.connection APi // Importing http module const http = require( 'http' );
// Setting up PORT const PORT = process.env.PORT || 3000; // Creating http Server var httpServer = http.createServer(
function (request, response) {
// Getting connection
// by using response.connection Api
const value = response.connection;
// Display result
response.end( "port address : "
+ value.address().port, 'utf8' , () => {
console.log( "displaying the result..." );
// Closing the server
httpServer.close(() => {
console.log( "server is closed" )
})
});
});
// Listening to http Server httpServer.listen(PORT, () => { console.log( "Server is running at port 3000..." );
}); |
Steps to run:
node index.js
Console Output:
Server is running at port 3000... displaying the result... displaying the result... server is closed server is closed
Browser Output: Paste the localhost address http://localhost:3000/ in the search bar of the browser.
Example 2: Filename: index.js
// Node.js program to demonstrate the // response.connection APi // Importing http module const http = require( 'http' );
// Request and response handler const http2Handlers = (request, response) => { // Getting connection
// by using response.connection Api
const value = response.connection;
// Display result
response.end( "family : "
+ value.address().family, 'utf8' , () => {
console.log( "displaying the result..." );
// Closing the server
httpServer.close(() => {
console.log( "server is closed" )
})
});
}; // Creating http Server and listing // on the port 3000 const httpServer = http.createServer( http2Handlers).listen(3000, () => {
console.log( "Server is running at port 3000..." );
});
