Node.js http.ServerResponse.setTimeout() 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
// 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
// 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
