How to configure CORS in node js?

CORS is a security mechanism implemented by web browsers to restrict cross-origin requests (requests made from a domain different from the one that served the web page).

It prevents malicious scripts from one domain from accessing resources from another domain without explicit permission.

Configuration Methods:

1. Using the cors Middleware (Express):

Install the cors middleware:

	npm install cors

Import and apply it in your Express app:

const express = require('express');
const cors = require('cors');
const app = express();


app.use(cors()); // Enable CORS for all routes (carefully consider security implications)
