Proxy requests to another source
You can use fetch()
to make requests to other sources via an Edge Function.
import { Context } from "@netlify/edge-functions";
export default async (request: Request, context: Context) => {
const joke = await fetch("https://icanhazdadjoke.com/", {
"headers": {
"Accept": "application/json"
}
});
const jsonData = await joke.json();
return Response.json(jsonData);
};

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!
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 a
/netlify/edge-functions
directory in your project.
