在 Typescripted Redux 中，我如何找到我的 root reducer 的类型？

Question

export const makeStore = () => {
  const store = configureStore({
    reducer: {
      reducer,
      growthReportSlice,
      selectBarSlice,
    },
    ....
  return store;
};
const dummy = makeStore();

export const wrapper = createWrapper(makeStore, { debug: true });
export type AppDispatch = typeof dummy.dispatch;
// export type RootReducer = ReturnType<typeof reducer> &
//   ReturnType<typeof growthReportSlice> &
//   ReturnType<typeof selectBarSlice>;
export const useAppDispatch = () => useDispatch<AppDispatch>();

我只需要根减速器的返回类型，但我有 3 个减速器组合。我怎样才能得到正确的输入？

Answer 1

你快完成了，你只需要组合你的减速器。

import {combineReducers} from 'redux'
const rootReducer = combineReducers({
  reducer,
  growthReportsSlice,
  selectBarSlice
})

type RootState = ReturnType<typeof rootReducer>

...
const store = configureStore({
    reducer: rootReducer,
...
