REDUX TOOLKIT

Redux Toolkit

Redux Toolkit is the official, recommended way to write Redux logic. It simplifies Redux by providing powerful tools and abstractions to reduce boilerplate and help you write efficient, readable, and maintainable Redux code.

Why Redux Toolkit?

Simplifies store setup with configureStore().
Provides createSlice() to define reducers and actions together.
Includes middleware like Redux Thunk by default for async logic.
Improves code readability and maintenance by reducing boilerplate.

    
      import { configureStore, createSlice } from '@reduxjs/toolkit';

      const counterSlice = createSlice({

        name: 'counter',

        initialState: 0,

        reducers: {

          increment: state => state + 1,

          decrement: state => state - 1

        }

      });

      export const { increment, decrement } = counterSlice.actions;

      const store = configureStore({

        reducer: { counter: counterSlice.reducer }

      });

      export default store;

Core Concepts

createSlice(): Automatically generates action creators and action types alongside reducers.
configureStore(): Sets up the Redux store with good default middleware and devtools enabled.
createAsyncThunk(): Simplifies async logic handling like API calls with automatic action dispatching.
Immer integration: Lets you write "mutating" syntax that safely produces immutable updates.

Why Should You Use Redux Toolkit?

Traditional Redux can be verbose and boilerplate-heavy. Redux Toolkit provides a clean, standardized approach that helps you avoid common mistakes, reduces code clutter, and improves developer experience.

In short: Redux Toolkit is the modern, recommended way to write Redux logic easily and efficiently.
