Where does node search for /favicon.ico ?

Hi all!
Noob here
That is, where is node file root?
Thanks

Hi @digimeas care to elaborate a little? 🙂
Node won't be searching for a favicon unless the code instructs it to do so.

Assuming your webpage includes a link for /favicon.ico (<link rel="icon" href="/favicon.ico">), the server would need to add handling for that route.
See the example here: https://stackoverflow.com/a/39553147

Hi @atlowChemi !
Got a little test page that's working fine, but the browser requests '/favicon.ico'. Node can't find '/favicon.ico' because, where is '/'? I can handle it easy in the createServer() code, but where does node think '/' is?
That is my question

Thanks
Doug

Node can't find '/favicon.ico' because, where is '/'?

This is the root route of the server.
Node doesn't automatically handle such an endpoint if not explicitly defined, so the endpoint would just "freeze" in pending state until the timeout. This means you need to explicitly handle this endpoint.

Here is an example for handling such an endpoint using http.createServer

const { createServer } = require('node:http');
const { join } = require('path');
const fs = require('fs');
const url = require('url');

// Location of your favicon in the filesystem.
const FAVICON = join(__dirname, 'public', 'favicon.ico');

const server = createServer(function(req, res) {
  const pathname = url.parse(req.url).pathname;

  // If this request is for the favicon, stream it in response.
  if (req.method === 'GET' && pathname === '/favicon.ico') {
    res.setHeader('Content-Type', 'image/x-icon');
    fs.createReadStream(FAVICON).pipe(res);
    return;
  }

  // This request was not asking for our favicon, handle it with further handlers.
  res.end();
});
server.listen(3000);

Does this answer your question?
Would you like to share a small example of your server so I might better understand the specifics of your question?

I thought maybe, like apache uses /var/www/html as '/', that node might do something similar

Thanks again

Node doesn't offer such a behavior by default 🙂
