I'm currently learning redux toolkit and I want to store dark mode state in localStorage so that if the users refresh the page, selected mode stays the same. My application looks like this:

index.js

import ReactDOM from "react-dom";
import { Provider } from "react-redux";
import { configureStore } from "@reduxjs/toolkit";
import darkModeReducer from "./darkModeSlice";
import App from "./App";

const store = configureStore({
  reducer: {
    darkMode: darkModeReducer,
  },
});

ReactDOM.render(
  <Provider store={store}>
      <App />
  </Provider>,
  document.getElementById("root")
);

darkModeSlice.js

import { createSlice } from "@reduxjs/toolkit";

const initialState = {
  darkMode: false,
};

export const darkModeSlice = createSlice({
  name: "darkMode",
  initialState,
  reducers: {
    toggleDarkMode: (state) => {
      state.darkMode = !state.darkMode;
    },
  },
});

export const { toggleDarkMode } = darkModeSlice.actions;

export default darkModeSlice.reducer;

What would be the optimal solution for this? Please note that I only want to store the dark mode state in local storage, so if I add other reducers in the future their values ​​won't be automatically saved there.
