The http.ClientRequest.writableEnded is an inbuilt application programming interface of class ClientRequest within http module which is used to check if the request.end() has been called or not.
Syntax:
const request.writableEnded
Parameters: This API does not accept any argument as parameter.
Return Value : This method returns true if and only if the request.end() has been called.
Example 1:
// Node.js program to demonstrate the
// request.writableEnded APi
// Importing http module
const http = require('http');
// Create an HTTP server
const server = http.createServer((req, res) => {
res.writeHead(200, { 'Content-Type': 'text/plain' });
res.end('okay');
});
// Now that server is running
server.listen(3000, '127.0.0.1', () => {
// make a request
const options = {
port: 3000,
host: '127.0.0.1',
headers: {
'Connection': 'Upgrade',
'Upgrade': 'websocket'
}
};
// getting client request
const req = http.request(options);
// checking if the request.end() has been called
// by using writableEnded api
if(req.writableEnded)
console.log('request.end() has been called')
else
console.log('request.end() has not been called')
process.exit(0)
});
