Node.js http.ServerResponse.setTimeout() Method

Node.js http.ServerResponse.writeProcessing() Method

Node.js http.ServerResponse.end() Method

The httpServerResponse.setTimeout is an inbuilt application programming interface of class ServerResponse within the HTTP module which is used to set the Socket’s timeout value to msecs (Milliseconds).

Syntax:

const response.setTimeout(msecs[, callback])

Parameters: This method takes the first parameter as socket time-out value in a millisecond, and the second parameter is a callback function which is optional.

Return Value: This method returns nothing but a call-back function for further operation.

Example 1: Filename-index.js

Javascript

// Node.js program to demonstrate the
// response.setTimeout() method
 
// 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) {
 
        // Setting the socket time out value
        // by using setTimeout method
        response.setTimeout(6000, () => {
            console.log("socket is destroyed due to timeout")
        })
    });
 
// 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...
socket is destroyed due to timeout

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

ERR_CONNECTION_REFUSED

Example 2: Filename-index.js

Javascript

// Node.js program to demonstrate the
// response.setTimeout() Method
 
// Importing http module
const http = require('http');
 
// Request and response handler
const httpHandlers = (request, response) => {
 
    // Setting the socket time out value
    // by using setTimeout method
    response.setTimeout(5000, () => {
        console.log("socket is destroyed due to timeout")
    })
}
 
// Creating http Server
const httpServer = http.createServer(
    httpHandlers).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...
socket is destroyed due to timeout

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

ERR_CONNECTION_REFUSED
