In this article, we will discuss the advantages of using Redux Toolkit over Core Redux. Redux Toolkit is a set of tools that make it easier to develop Redux applications. It provides a number of features that can help you to write more concise, maintainable, and efficient code.

Redux toolkit is a better tool to write redux logic because when we are writing the core redux then we need to write more boiler code. It makes it faster to write the redux logic. In the core redux there are many things that we need to do manually Like creating the actions. In react we can't mutate the state variable so we do not mutate the state of the redux store in reducers that make hard the state changes.

Redux toolkit is officially recommended by Redux since 2019.

Redux Toolkit Setup

here are some steps for creating the react project with redux.

1. Create a react app with Vite builder

npm init vite@latest React-ReduxToolkit -- --template react-ts

2. Go to the newly created folder

here is the command for navigating to the folder

cd React-ReduxToolkit

3. Install the @reduxjs/toolkit and react-redux library

npm install @reduxjs/toolkit react-redux

4. Now run the web App

npm run dev

Redux Toolkit Vs Redux

here is some major difference between Redux Toolkit and Redux

  • There is a lot of boilerplate code in Redux. this problem is reduced in Redux Toolkit.

  • In core Redux we need to install additional tools like immer, reselect, Normalizer etc. These libraries are inbuild in the redux Toolkit.

  • In Redux we can't mutate the state directly. Redux toolkit provides this thing.

Redux Toolkit Vs Context API

  • Redux Toolkit is an external library but Context API is provided by the React library.

  • Both tools are for maintaining the state globally but the Redux toolkit also makes it predictable.

  • In Context, there is no way to test the errors. Redux Toolkit makes error handling easier.

  • We can play or pause in the Redux toolkit to see changes.

Code snippets for Redux Toolkit

Creating Store

export const store = configureStore({
    reducer:{
        router: routerReducer,
        quote : quoteReducer
    },
    middleware:[sagaMiddleWare , routerMiddleware]
})

In the Redux toolkit creating a store is a much easier task than the core Redux. It can combine the reducers and pass the middleware in easily.

Reducers

const initialState = {
  loading: false,
  quotes: {} as { [id: string]: { _id: string; contant: string } },
};
type State = typeof initialState;

const todoSlice = createSlice({
  name: "quote",
  initialState,
  reducers: {
    loading: loadingFunction,
    fetchQuote: getQuote,
  },
});
export const { loading , fetchQuote } = todoSlice.actions;
export const todoReducer = todoSlice.reducer;

here we don't need to create the reducers Redux toolkit provides slices that can create actions and reducers for the developer. There are many things we can do here in the concept of entityAdapter This tool is for managing our state automatically.

Thank you❤️ for the reading. Please share your suggestion in the comments.
