const main = async () => {
  const SCOPE_LIST = ['public', ...];

  // Auth via client
  await auth.login('CLIENT_ID', 'CLIENT_SECRET', SCOPE_LIST);

  // Auth via lazer credentials
  await auth.login_lazer('YOUR_LOGIN', 'YOUR_PASSWORD');

  // Auth via oauth2
  await auth.authorize_cli('CLIENT_ID', 'CLIENT_SECRET', 'CALLBACK_URL', SCOPE_LIST);

  return url;
};

const callback_page = async () => {
  const user_data = await auth.authorize(code, 'GAMEMODE', 'CLIENT_ID', 'CLIENT_SECRET', 'CLIENT_CALLBACK_URL');
  return user_data;
};

  const diff_file = tools.download.difficulty(2379651, './', '2379651')

  // Calucalute pp for a difficulty
  const pp_calc = tools.pp_calc(2379651)

  // Rank letter from hits
  const rank = tools.rank(
    {
      geki: 236,
      katu: 43,
