How does helmet.crossOriginResourcePolicy work?

helmet.crossOriginResourcePolicy is a middleware function provided by the Helmet library in Node.js that adds the Cross-Origin-Resource-Policy header to HTTP responses with a given policy directive. This header is used to control which resources can be shared by different origins on the web. When set to same-site, resources can only be shared by the same origin, and when set to cross-origin, resources can be shared by other origins as well.

const express = require("express");
const helmet = require("helmet");

const app = express();

app.use(helmet.crossOriginResourcePolicy());

// ...rest of the code

This middleware sets the Cross-Origin-Resource-Policy header to "same-origin" on all responses.
