Edge Functions Examples / Block content according to country

Block content according to country

You can use geolocation data to identify a user's country and block content if required.

Geolocation information is available on the Context.geo object.

import { Context } from "netlify:edge";

export default async (request: Request, context: Context) => {
  const countryCode = context.geo?.country?.code || "US";
  const countryName = context.geo?.country?.name || "United States of America";

  if (countryCode === BLOCKED_COUNTRY_CODE) {
    return new Response(`We're sorry, you can't access our content from ${countryName}!`, {
      headers: { "content-type": "text/html" },
      status: 451,

  return new Response(`Hello there! You can freely access our content from ${countryName}!`, {
    headers: { "content-type": "text/html" },

What are Edge Functions?

Using JavaScript and TypeScript, Netlify Edge Functions give you the power to modify network requests to localize content, serve relevant ads, authenticate visitors, A/B test content, and much more! And this all happens at the Edge — directly from the worldwide location closest to each user.

To use Edge Functions on Netlify, add JavaScript or TypeScript files to an edge-functions directory in your project, and add [[edge_functions]] entries to your netlify.toml file.
