const app: Application = express();

const verifyFn: VerifyFunction = (verifyHeaders, done) => {
  console.log('have user data found in headers', verifyHeaders);
  return !verifyHeaders ? done(null) : done(null, { id: 'user_id' });
};

const createStrategy = (): Strategy => new ForwardAuthStrategy({ authHeaders }, verifyFn);

use(createStrategy());
