  • Last Updated : 20 Dec, 2020

The http.IncomingMessage.aborted is an inbuilt application programming interface of class IncomingMessage within HTTP module which is used to check if the request has been aborted or not.

Syntax:

const message.aborted

Parameters: This method does not accept any argument as a parameter.

Return Value: This method returns true if and only if the request has been aborted.

Example 1: Filename: index.js



Javascript




// Node.js program to demonstrate the  
// request.aborted Method 
  
// Importing http module 
var http = require('http');
  
// Setting up PORT 
const PORT = process.env.PORT || 3000;
  
// Creating http Server 
var httpServer = http.createServer(
    function (request, response) {
  
  // Checking if request is aborted or not
  // by using request.aborted method
  const value = request.aborted;
  
  // Display result
  response.end("request has been aborted : "
        + value, 'utf8', () => {
    console.log("displaying the result...");
  
    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...
displaying the result...
server is closed

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

request has been aborted : false

Example 2: Filename: index.js

Javascript




// Node.js program to demonstrate the  
// request.aborted Method 
  
// Importing http module 
var http = require('http');
  
// Request and response handler 
const http2Handlers = (request, response) => {
  
  // Checking if request is aborted or not
  // by using request.aborted method
  const value = request.aborted;
  
  // Display result
  response.end("request has been aborted : "
        + value, 'utf8', () => {
    console.log("Writing remotefamily of socket...");
  
    httpServer.close(() => {
      console.log("server is closed")
    })
  });
};
  
// Creating http Server 
var 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 go to http://localhost:3000/ in the browser, you will see the following output:
