求指教一个 redux 相关的问题，先谢过了

实际开发中，尤其是面向 c 端的用户，任何业务和用户操作我认为都应该包含这四种状态，loading，error，empty，success，为了简化 actionType 的分散性，所以就简单封装了一个 acitonModel

/**
 * generator common actionModel 普通模型
 * @param {*} prefix 前缀，需要保证唯一性
 */
export function generatorCommonActionModel(prefix) {
    const load_loading_action_type = prefix + common_load_loading;
    const load_empty_action_type = prefix + common_load_empty;
    const load_error_action_type = prefix + common_load_error;
    const load_success_action_type = prefix + common_load_success;
    const get_common_action_type = prefix + get_common;
    const reset_action_type = prefix + common_reset;

    return {
        prefix,
        load_loading_action_type,
        load_empty_action_type,
        load_error_action_type,
        load_success_action_type,
        get_common_action_type,
        reset_action_type,
        loadLoadingActionCreator: params => ({ type: load_loading_action_type, params }),
        loadEmptyActionCreator: params => ({ type: load_empty_action_type, params }),
        loadErrorActionCreator: params => ({ type: load_error_action_type, params }),
        loadSuccessActionCreator: (data, params) => ({ type: load_success_action_type, payload: { data, params } }),
        getCommonActionCreator: params => ({ type: get_common_action_type, params }),
        resetActionCreator: params => ({ type: reset_action_type, params })
    }
}

actionModel 根据 key 的唯一性来区分，使用的时候直接使用该函数可以快速生成对应的 action 模型，实际运用中也确实感受到了其方便性，但随之带来的问题就来了，就是 reducer 层，始终想不到该如何去优化处理，目前的做法

/**
 * 统一处理 commonModelActions
 * @param {*} actionModel 需遵循 actionHelp 规范
 * @param {*} stateModel  需遵循 stateModel 中的 commonStateModel 数据模型规范
 * @param {*} action dispatch 出来的 action
 */
export function reducerGeneratorCommonActionModel(actionModel, stateModel, action) {
    switch (action.type) {
        case actionModel.load_loading_action_type:
            return { ...stateModel, load_status: NetWorkComponent.LOAD_LOADING };
        case actionModel.load_empty_action_type:
            return { ...stateModel, load_status: NetWorkComponent.LOAD_EMPTY };
        case actionModel.load_error_action_type:
            return { ...stateModel, load_status: NetWorkComponent.LOAD_ERROR };
        case actionModel.load_success_action_type:
            return {
                ...stateModel,
                load_status: Array.isArray(action.payload.data) ? action.payload.data.length > 0 ? NetWorkComponent.LOAD_SUCCESS : NetWorkComponent.LOAD_EMPTY : NetWorkComponent.LOAD_SUCCESS,
                data: action.payload.data
            };
        default:
            return stateModel;
    }
}

感觉这样去写，反而更累了，所以想问下 v 友门，这块要如何去设计和优化啊，再次感谢
