createStore is @deprecated so im trying to replace with configurationStore

Question

createStore is @deprecated so im trying to replace with configurationStore, i think the post data from my cluster is not showing because of that

 ``` import React from 'react'; import ReactDom from 'react-dom/client'; import { Provider } from 'react-redux'; import {createStore, applyMiddleware, compose } from 'redux'; import thunk from 'redux-thunk'; import reducers from "./reducers"; import App from './App' const store = createStore(reducers, (compose(applyMiddleware(thunk)))) const root = ReactDom.createRoot(document.getElementById("root")); root.render( <Provider store={store}> <App /> </Provider> );

And im trying to do it like this:

    

 import React from 'react'; import ReactDom from 'react-dom/client'; import { Provider } from 'react-redux'; import { applyMiddleware, compose } from 'redux'; import thunk from 'redux-thunk'; import { configureStore } from '@reduxjs/toolkit' import reducers from "./reducers"; import App from './App' const store = configureStore(reducers, (compose(applyMiddleware(thunk)))) const root = ReactDom.createRoot(document.getElementById("root")); root.render( <Provider store={store}> <App /> </Provider> ); ```

Of Course it didn't work i'm trying to figure out how it could be

You would do

const store = configureStore({ reducer: reducers })

The thunk middleware is active automatically. compose and applyMiddleware are not needed any more. So is combineReducers .

If you had

const reducers = combineReducers({
  a: reducerA,
  b: reducerB
})

you could also just instead do

const store = configureStore({ 
  reducer: {
    a: reducerA,
    b: reducerB
  }
})

If you were still using createStore , that means that you were generally using an outdated style of Redux that is about 4x times the code of modern Redux.

Modern Redux does not use switch..case reducer, ACTION_TYPE constants, immutable reducer logic, hand-written action creators or connect & mapStateToProps . You might have been misled by an outdated tutorial.

I would highly recommend you to follow the official Redux tutorial which will leave you with knowledge of modern Redux and in the end much cleaner and easy to maintain code.
