Understanding Redux Toolkit Store

Redux is a predictable state container for JavaScript applications that helps managing the application's state in a more structured way. Redux Toolkit is a package that aims to make Redux development quicker and easier by providing easier ways to write actions and reducers.

What is a store?

A store is an object that holds the complete state tree of your application. The store is the single source of truth for your application state, and it provides methods to update, access, and subscribe to the state. In Redux, the store is created using the createStore() method.

What is the Redux Toolkit Store?

The Redux Toolkit Store is a pre-configured version of the Redux store that includes some opinionated defaults and simplifies the setup process by wrapping the createStore() method. It is created using the configureStore() method provided by Redux Toolkit.

Creating a Redux Toolkit Store

import { configureStore } from '@reduxjs/toolkit';
import rootReducer from './reducers';

const store = configureStore({
  reducer: rootReducer

In the above code, we import the configureStore() method and pass our root reducer as an argument to create our store object.

Features of the Redux Toolkit Store

  • Simplified Setup: The configureStore() method includes sensible defaults for setting up the store, such as serializable action checking and thunk middleware.
  • Immutability: The Redux Toolkit Store uses Immer internally, which allows us to write simpler and more intuitive immutable updates.
  • DevTools: The Redux Toolkit Store includes built-in support for the Redux DevTools extension, which provides debugging and time-traveling capabilities.

It provides a number of features, including simplified setup, immutability, and DevTools integration, that can help make Redux development quicker and easier.
