Stop writing boilerplate Redux code. Redux Toolkit modernizes state management with createSlice, RTK Query, and Immer — here's how to use them effectively in large-scale apps.
Redux Toolkit (RTK) is the official, opinionated way to write Redux logic. It includes utilities to simplify common Redux use cases.
The createSlice API automatically generates action creators and action types that correspond to the reducers and state.
const counterSlice = createSlice({
name: 'counter',
initialState: { value: 0 },
reducers: {
increment: state => { state.value += 1 },
decrement: state => { state.value -= 1 },
},
});
RTK Query is a powerful data fetching and caching tool built right into Redux Toolkit. It eliminates the need to write thunks and reducers for API calls.
Always normalize your state shape for complex data. Use RTK Query for all server-side data. Keep UI state separate from server state.
Redux Toolkit has dramatically simplified Redux development. With RTK Query handling data fetching and Immer enabling mutable-style updates, the boilerplate is gone.

RTK Query changed everything for me. No more manual cache management!
