Migrate a legacy Redux codebase (createStore, action constants, switch reducers) to Redux Toolkit incrementally — one slice at a time — without changing your state shape or breaking existing tests.
Redux Toolkit's createSlice lets you write mutable-looking reducers that stay immutable under the hood. See a concrete todo example, the trade‑offs, and a quick verification script.
Learn how createSlice reduces boilerplate, generates action creators, and lets you write mutable‑style reducers that stay immutable via Immer.
Learn how Redux Toolkit's createSlice cuts Redux boilerplate, uses Immer for immutable updates, and simplifies React state management with a practical todo-list example.
Learn how createSlice bundles reducers, actions, and initial state, leverages Immer for safe mutations, and integrates with DevTools for clearer debugging.
Dispatch fires but the UI stays stale? Diagnose accidental state mutations in Redux reducers with reference-equality checks, DevTools traces, and targeted immutable-update fixes.
Redux Thunk lets action creators return functions for async work while keeping reducers pure. This post shows a concrete fetch pattern with createAsyncThunk, explains where thunks fit in the unidirectional flow, and outlines when to switch to RTK Query instead.
Decide whether to use RTK Query or hand‑written async thunks for server data, and how to structure client‑only state with Redux Toolkit. A compact comparison table, trade‑off discussion, and a typed store implementation are included.
Decide between standard Redux reducers and Redux Toolkit (RTK). Learn how Immer simplifies nested state updates and when to prioritize manual immutability for performance.
