Redux Using Method And Example

🔭 What is Redux?

step 1 = Setup Store.
step 2 = Connect redux store with react in main.tsx / app.tsx (provider)
step 3 = Setup the custome hook (only relatable for ts usage)
step 4 = Create Slice (Name, initalState, reducer).
step 5 = Connect you slice with the redux store.
For Consuming data
useAppSelector => store

👯 Why use Redux?

setupRedux

#step one
install redux ...

#step two
create folder "redux" in src

#step three
create "store.js" in  redux folder
import { configureStore } from '@reduxjs/toolkit'
import { api } from './api/apiSlice'
import cartSlice from './features/cart/cartSlice'

export const store = configureStore({
    reducer: {
        cart: cartSlice,
        [api.reducerPath]: api.reducer,
    },
    middleware: (getDefaultMiddleware) =>
        getDefaultMiddleware().concat(api.middleware),
    devTools: true
})


interrogate  store with provider

main.jsx -----------
import { store } from './redux/store.js';
import { Provider } from 'react-redux';

ReactDOM.createRoot(document.getElementById("root")).render(
  <React.StrictMode>
    <Provider store={store}>
      <AuthProvider>
        <ChakraProvider>
          <HelmetProvider>
            <QueryClientProvider client={queryClient}>
              <RouterProvider router={router} />
            </QueryClientProvider>
          </HelmetProvider>
        </ChakraProvider>
      </AuthProvider>
    </Provider>
  </React.StrictMode>
);


#step four
create a "features" folder in redux folder
#step six
create "cart, order, product, user, etc" folder in the features folder 

#step seaven
create a "cartSlice" folder in cart folder
create a "apiSlice" folder in api folder
