import asyncWrap from 'async-wrapus';

  // Can throw exception!
  return await someApiRequest();
};

const someMethod = async () => {
  /**
   * err: null | Error
   * result: Result of asyncRequest | null
   */
  const [err, result] = await asyncWrap(asyncRequest());

  if (err) {
    // do something with exception
  }

  if (result) {
    // do something with result
  }
};
