Edge Functions Examples / Proxy requests to another source

Proxy requests to another source

You can use fetch() to make requests to other sources via an Edge Function.

import { Context } from "netlify:edge";

export default async (request: Request, context: Context) => {

  const joke = await fetch("https://icanhazdadjoke.com/", {
    "headers": {
      "Accept": "application/json"
  const jsonData = await joke.json();
  return context.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! 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.
