Redux Toolkit is a powerful library that simplifies managing the state in React applications using Redux. Here's a summary of the key topics related to Redux Toolkit:

Redux Store

• The Redux store serves as the single source of truth for the application's state;
• Redux Toolkit's configureStore function simplifies store configuration by providing sensible defaults and built-in middleware;
• The store configuration includes specifying reducers for different state changes.

Redux Store into the App

• The Provider component from the react-redux library is used to make the Redux store available to the components in the app;
• The Provider component wraps the app's root component and accepts the Redux store as a prop.

Actions and Action Creators

• Actions describe the changes that need to be made to the state and are created using action creators;
• Redux Toolkit provides the createAction function to simplify the creation of action creators;
• Action creators generate action objects with a type property that identifies the action when dispatched.

Reducers and State Management

• Reducers specify how the state should change in response to dispatched actions;
• Redux Toolkit's createReducer function simplifies the creation of reducers by automatically generating action cases based on provided functions;
• Reducers take the current state and an action as parameters and return the new state.

Connect Redux and React

• The useSelector hook from react-redux accesses state values from the Redux store in React components;
• The useDispatch hook is used to access the dispatch function, which allows dispatching actions to update the Redux store;
• Components can subscribe to the state and dispatch actions using these hooks, enabling them to interact with the Redux store.

Note

Great! You've covered the fundamentals of the Redux Toolkit, including creating actions, reducers, and the Redux store.
For further assistance, it is recommended to refer to the official Redux Toolkit documentation. Happy Redux-ing!
