Is there a way to do basic authentication?
I would like to implement basic authentication and use it privately.

You can check credentials inside a handler and return a 401 response with a WWW-Authenticate header if they are invalid:

import { Handlers } from "$fresh/server.ts";

const USER = "alice"
const PASSWORD = "secret"

export const handler: Handlers = {
  GET(req) {
    if (req.headers.get("Authorization") !== `Basic ${btoa(`${USER}:${PASSWORD}`)}`) {
      const headers = new Headers({
        "WWW-Authenticate": 'Basic realm="Fake Realm"',
      });
      return new Response("Unauthorized", { status: 401, headers });
    }
    return new Response("Fresh is awesome!");
  },
};

Hope it helps!
