redux中使用TS每次都要定义一遍类型？

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

typing文件夹下创建Redux.d.ts声明文件

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，这样使用就不用再import type { Redux } from \'@/typings/redux\'; 了
export = MyRedux; 

// 由于使用了import，此文件变成局部模块，其他地方使用只能import导入(import type { Redux } from \'@/typings/redux\';)才能使用
export as namespace MyRedux;

如何使用
models文件夹下创建staff.ts

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

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

export default StaffSettingsModel;
