绑定动作创建者打字稿组件类型

Question

我在redux中有一整套键入的动作创建器，我绑定到react组件中的props。我很好奇是否为组件道具添加类型是标准做法，即使他们收到的动作创建者已经输入过。

// Action Creator: Here I am typing the action creator for the first time
export interface FetchingUserSuccessReturn {
  type: string;
  uid: string;
  user: any;
  timestamp: number;
}

export function fetchingUserSuccess(uid: string, user: any, timestamp: number): FetchingUserSuccessReturn {
  return {
    type: FETCHING_USER_SUCCESS,
    uid,
    user,
    timestamp
  };
}

是否通常会忽略组件道具界面，因为道具已经被键入（作为动作创建者）？

// Component receiving action creator
// It feels like I'm re-typing the action creators in this interface
interface MainContainerProps {
  fetchingUserSuccess: (uid: string, user: any, timestamp: number) => FetchingUserSuccessReturn;
}


export default connect(
  () => (),
  (dispatch) => {
    return bindActionCreators({
      fetchingUserSuccess: userActionCreators.fetchingUserSuccess,
    }, dispatch);
  }
)(MainContainer);

export class MainContainer extends React.Component<MainContainerProps, any>     {
