JSON Response

You can use Edge Functions to return a JSON response by returning context.json() with a JavaScript object — no need to JSON.stringify!

In this example, we return a JSON object containing hello: "world".

import type { Context } from "netlify:edge";

export default async (request: Request, context: Context) => {
  return context.json({ hello: "world" });
};

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.
