Combining Reducers in Redux Toolkit
In Redux Toolkit, multiple reducers can be combined to manage different parts of the application's state tree. Each slice created with createSlice() generates its own reducer, which can then be combined using the combineReducers function or automatically merged in configureStore().
Use
combineReducers()from Redux to manually merge multiple slice reducers into a root reducer.Pass an object of slice reducers directly to
configureStore(), which internally usescombineReducers().Each key in the combined reducer object corresponds to a specific state field managed by its respective slice.
By combining reducers, each slice manages its own piece of state while contributing to a unified global store. This modular approach keeps the Redux architecture scalable and maintainable.
