expressjsHow do I set up a favicon with Express.js?

To set up a favicon with Express.js, you must first create a favicon.ico file and save it in the root directory of your project. Then, you must require the serve-favicon middleware and include it in your Express.js app. Here is an example of how to do this:

const express = require('express');
const favicon = require('serve-favicon');
const path = require('path');

const app = express();

app.use(favicon(path.join(__dirname, 'favicon.ico')));

This will serve the favicon.ico file whenever the /favicon.ico path is requested. No output is produced.

The code above consists of the following parts:

• const express = require('express'); - This line imports the Express.js library.
• const favicon = require('serve-favicon'); - This line imports the serve-favicon middleware.
• const path = require('path'); - This line imports the path library, which is used for manipulating file paths.
• const app = express(); - This line creates an Express.js app.
• app.use(favicon(path.join(__dirname, 'favicon.ico'))); - This line uses the serve-favicon middleware with the path to the favicon.ico file.
