Why my node server processes the request twice?

Question

I have following simple node server.

const http = require(\'http\');

http.createServer(function(req, resp) {

    console.log(\"request arrived.\")
    resp.wri         


        

Answer 1

It is most likely that the browser is requesting for the favicon.ico file. You can confirm that by printing the URL, like this

console.log("request arrived for URL", req.url);

When I tried this on my machine, with Chrome browser, I got

request arrived for URL /
request arrived for URL /favicon.ico

If you want to avoid that, then you need to handle the favicon request specially. Probably, you can do something like this, as shown here

if (req.url === '/favicon.ico') {
    resp.writeHead(200, {'Content-Type': 'image/x-icon'} );
    resp.end();
    console.log('favicon requested');
    return;
}

console.log("request arrived.")
resp.writeHead(200, { 'Content-Type': 'application/json' });
resp.end("Hello world!!");
