Edge Functions Examples / Geolocation


You can use Edge Functions to get information about a user's location to serve location-specific content and personalize their experience.

  • United States
  • Your country name United States
  • Your country code US
  • Your city Ashburn

Geolocation information is available on the Context.geo object.

import { Context } from "netlify:edge";

export default async (request: Request, context: Context) => {
  // Here's what's available on context.geo

  // context: {
  //   geo: {
  //     city?: string;
  //     country?: {
  //       code?: string;
  //       name?: string;
  //     },
  //     subdivision?: {
  //       code?: string;
  //       name?: string;
  //     },
  //   }
  // }

  return context.json({
    geo: context.geo,
    header: request.headers.get("x-nf-geo"),

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.

Learn more in the docs.
