Geolocation
You can use Edge Functions to get information about a user's location to serve location-specific content and personalize their experience.
- Your country name United States
- Your country code US
- Your city Columbus
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.
