Problem Statement
What is the step-by-step process for migrating an existing Redux application to Redux Toolkit?
Explanation
Start migration by installing Redux Toolkit alongside existing Redux without removing anything, then convert your store creation to use configureStore which automatically includes DevTools and middleware while still accepting your existing reducers. Next, identify a small, isolated slice to convert first, rewrite it using createSlice which generates actions automatically, update components to use the new action creators, and test thoroughly before moving to the next slice. Convert action creators to use createAsyncThunk for async operations, gradually replace hand-written reducers with createSlice reducers, migrate to RTK Query if you have extensive data fetching replacing thunks and hand-written cache logic, and update tests to work with new patterns. Complete the migration by removing old Redux files once all features are converted, cleaning up unused dependencies, and updating documentation with new patterns.
