How to short-circuit those annoying favicon requests in node.js
// early experiments with node had mysterious double requests
// turned out these were for the stoopid favicon
// here's how to short-circuit those requests
// and stop seeing 404 errors in your client console
var http = require('http');
http.createServer(function (q, r) {
// control for favicon
if (q.url === '/favicon.ico') {
r.writeHead(200, {'Content-Type': 'image/x-icon'} );
r.end();
console.log('favicon requested');
return;
}
// not the favicon? say hai
console.log('hello');
r.writeHead(200, {'Content-Type': 'text/plain'} );
r.write('Hello, world!');
r.end();
}).listen(8000);
console.log('Server running at http://127.0.0.1:8000/');

Glad it was useful!

In case someone stumbles upon this in the future.. If you are running nginx in front of node.js you can also block favicon requests by adding this line:

location = /favicon.ico { access_log off; log_not_found off; }

Thanks. This is exactly what I was looking for. Wish there were more useful, small code snippets like this around the Net.

Thanks so much! Exactly what I was looking for.

helpful,thanks!

Great and simple! Thank you.

Thanks for this! Chrome causes this issue.

If you are using express you can do it like this

app.use(express.favicon(__dirname + '/public/favicon.ico'));

God Bless you~

if you are interested I made and express middleware based on this gist; you can find it here: https://github.com/mattiaerre/express-favicon-short-circuit

// cc @kentbrew

Worth noting that this only works if you call return form the main app.js file. I put the above code in a separate router.js file, and it didn't work as expected.
