关于redux:redux中使用TS每次都要定义一遍类型

umi 架构下：ts 我的项目中 redux 定义 module 每次都要写一遍类型定义麻烦得很

typing 文件夹下创立 Redux.d.ts 申明文件

import type {Effect, Subscription, ImmerReducer} from 'umi';

declare module MyRedux {
  // model
  type Models<T> = {
    namespace?: string;
    state: T;
    effects: Record<string, Effect>;
    reducers: Record<string, ImmerReducer<T>>;
    subscriptions?: Record<string, Subscription>;
  };
}
// 导出成模块，再全局导出 MyRedux，这样应用就不必再 import type {Redux} from '@/typings/redux'; 了
export = MyRedux; 

// 因为应用了 import，此文件变成部分模块，其余中央应用只能 import 导入 (import type { Redux} from '@/typings/redux';) 能力应用
export as namespace MyRedux;

如何应用
models 文件夹下创立 staff.ts

type StaffSettingState = {staff: Record<string, never>;};

const StaffSettingsModel: MyRedux.Models<StaffSettingState> = {
  namespace: 'staffSettingsModel',
  state: {staff: {}
  },
  effects: {},
  reducers: {},};

export default StaffSettingsModel;
