reduxでmiddlewareを使わない非同期処理

action.js

export function isLogin() {
  return async (dispatch) => {
    try {
      const user = await User.get('user');
      dispatch({
        type: actionTypes.LOADED,
        isLoading: false,
        isLogin: true,
        user,
      });
    } catch (e) {
      dispatch({
        type: actionTypes.NOT_LOGIN,
        isLoading: false,
      });
    }
  };
}
