Edge Functions Examples / Environment variables

Use environment variables

To access your Netlify environment variables in Edge Functions, use the Netlify.env API.

import type { Context } from "@netlify/edge-functions";

export default async (request: Request, context: Context) => {
  const value = Netlify.env.get("MY_IMPORTANT_VARIABLE");

  return new Response(`Value of MY_IMPORTANT_VARIABLE is "${value}".`, {
    headers: { "content-type": "text/html" },

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.
