Use environment variables
Netlify Edge Functions support open-source Deno APIs. To access your Netlify environment variables in Edge Functions, use the Deno.env
API.
import type { Context } from "https://edge.netlify.com";
export default async (request: Request, context: Context) => {
const value = Deno.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, and add [[edge_functions]]
entries to your netlify.toml file.
