/**
* A map of the URLs to redirect to
* @param {Object} countryMap
*/

US: "https://example.com/us",
EU: "https://example.com/eu",
};
// Use the cf object to obtain the country of the request
// more on the cf object: https://developers.cloudflare.com/workers/runtime-apis/request#incomingrequestcfproperties
const country = request.cf.country;
if (country != null && country in countryMap) {
const url = countryMap[country];
// Remove this logging statement from your final output.
console.log(
`Based on ${country}-based request, your user would go to ${url}.`,
);
