What Redux Toolkit Solves
Classic Redux required action types, action creators, reducers, and often middleware — all in separate files. Redux Toolkit collapses this into slices, uses Immer for immutable updates, and includes Thunk middleware by default.
Creating a Slice
createSlice accepts a name, initial state, and a reducers object. Each reducer function receives state and action. Because Immer is built in, you can write code that appears to mutate state directly — Immer converts it to an immutable update behind the scenes.
Async Operations with createAsyncThunk
createAsyncThunk generates pending, fulfilled, and rejected action types automatically. Add extra reducers with builder.addCase to handle each lifecycle state. This replaces the manual thunk boilerplate completely.
RTK Query for Data Fetching
RTK Query is a powerful data fetching and caching tool built on top of Redux Toolkit. Define an API with endpoints and it automatically generates hooks, handles caching, invalidation, and loading states — no manual fetch code required.
