node.js - Express js prevent GET /favicon.ico

Question

In every request, my server is receiving GET request to /favicon.ico, even when it's REST api that not include html file. Why is this happening and how can I prevent this request?

Answer 1

Browsers will by default try to request /favicon.ico from the root of a hostname, in order to show an icon in the browser tab.

If you want to avoid this request returning a 404, you can either:

• Supply a favicon.ico file that is available at the root of your site.
• Use a module such as serve-favicon to point requests to a specific file.

• Catch the favicon.ico request and send a 204 No Content status:

  app.get('/favicon.ico', (req, res) => res.status(204));
