I have a HTTP server that will always result in HTTP timeout, e.g.

const server = http.createServer((req, res) => 
 setTimeout(() => 
 res.writeHead(200);
 res.write('OK');
 res.end();
 , 2000);
);
server.setTimeout(1000);
server.on('timeout', (socket) => 
 // How to produce a custom HTTP response here?
);

HTTP server "timeout" event is emitted with socket reference. How do I use socket to encode HTTP response?

I know that I can stitch the response myself at a low-level, e.g.

server.on('timeout', (socket) => 
 socket.write([
 'HTTP/1.1 408 Request Timeout',
 'Connection: close'
 ].join('n') + 'nn');

 socket.end();
);

But is there a way to use the HTTP response interface, i.e. writeHead/ write/ end?

node.js

You could use the setTimeout function on the response object. Consider this simple example:

const http = require('http');
const port = 3000;

const requestHandler = (req, res) => 
 res.setTimeout(Math.random() * 2500, () => 
 res.writeHead(408);
 res.end();
 );
 setTimeout(() => 
 if (res.headersSent) 
 return;
 
 res.writeHead(200);
 res.write('OK');
 res.end();
 , 2000);
;

const server = http.createServer(requestHandler);

server.listen(port, (err) => 
 if (err) 
 return console.log('an error happened', err)
 
 console.log(`server is listening on $port`)
);

If you call localhost:3000 in your web browser you'll now either see 200 OK or a 408 error. Note that you'll need to handle already sent headers if the random timeout was less than 2000 ms.
