Slice Wiring Mismatch

rtk-slice-wiring-mismatch

Redux Toolkit slices fail to update because dispatched action types, RTK Query endpoint lifecycles, and configuration keys don’t line up with what createSlice/extraReducers expect, so fulfilled results never merge or state shape/type assumptions break UI behavior.

MATCHESSolution

Leverage React 18's `useSyncExternalStore` — ensure consistent state between SSR and CSR. Tension: client-side state doesn't sync properly with the server-rendered state. Outcome: to ensure consistent state between SSR and CSR.

MATCHESSolution

Update the store slice directly without the functional `set` callback, e.g. `set({ storagePolicySettings })` instead of spreading and returning a new state object.

MATCHESSolution

This issue is solved here — https://docs.pmnd.rs/zustand/guides/slices-pattern. Tension: However for some reason I get some errors:.

MATCHESSolution

Define set/get action functions in the Zustand state slice so they can be reused by any component consistently, using state helpers like get() inside the slice for current state access.

MATCHESSolution

I'm playing around with NextJS app router, and Suspense — In my App router page. Tension: this suspense boundary won't do anything.

MATCHESSolution

use hash-based routing — react + tanstack router + github pages. Tension: The default "browser" routing will exhibit the behaviour you describe.

MATCHESSolution

Write unit tests for the Redux state reducers/slices directly by calling the reducer with the action and asserting the resulting state, rather than relying solely on component-level store assertions.

MATCHESSolution

Create a separate slice that updates history via `extraReducers` using `api.endpoints.<endpoint>.matchFulfilled` (e.g., push `action.payload` into history). Alternatively, dispatch a normal Redux action when the query is fulfilled (via query lifecycle hooks or other middleware-like dispatch) to store the data.

MATCHESSolution

Move the `router.post` logout call and `onFinish` handling into an async action (e.g., `createAsyncThunk`), then update `isLogouting`/`isOpeLogoutDialogue` in the slice via `extraReducers` on pending/fulfilled/rejected to ensure the flags are reset.

MATCHESSolution

Align the state interface with the real thunk payload types (use `Goal[]` instead of `[]`) and explicitly type/cast the thunk `fulfilled` payload and the reducer `action` (including casting `action.error` to `string`).

MATCHESSolution

you need to use the specific customized `AppDispatch` type from the store — For `useDispatch`, the default `Dispatch` type does not know about thunks. Outcome: Update your `src/Client/RedGranite.Client.Web/src/app/hooks.ts` file to the current suggestion.

MATCHESSolution

Update the selector to read from the correct key, e.g. useSelector((state) => state.fileUpload.files), or change the store reducer key to match the selector.

MATCHESSolution

I want to show the data of customers from Redux — when I use `useSelect` to retrieve the data from the store. Tension: entries.map is not a function. Outcome: retrieve the data from the store.

MATCHESSolution

Create a root reducer with `combineReducers({ addUser: addUserSlice.reducer })`, pass that into `persistReducer` with `whitelist: ['addUser']`, and ensure the component uses `persistor` via `PersistGate`.

MATCHESSolution

Tension: cannot itself access any Redux context because none is provided to it from higher up the ReactTree. Outcome: so it can access the provided Redux context.

MATCHESSolution

You are not allowed in Redux, ever, to dispatch from inside a reducer. — Reducer logic has to be a pure synchronous function without side effects. Tension: You might want to do the logic you are currently doing in a thunk or with the listener middleware instead. Outcome: You have to use `createAsyncThunk` for that.

MATCHESSolution

Install the Redux DevTools browser extension and rerun the app so `composeWithDevTools` can work correctly.

MATCHESSolution

Redux-Toolkit also ships with Thunk middleware included and enabled by default — If you needed to configure and/or add middleware, use the `getDefaultMiddleware` utility.

MATCHESSolution

Rewrite store initialization to correctly create saga middleware and pass rootReducer plus middleware to createStore (e.g., use sagaMiddleware.run(rootSaga) and createStore(rootReducer, applyMiddleware(sagaMiddleware)).

MATCHESSolution

const user = useSelector(state => state.auth.authData); — The `Navbar` component should read the user data that was stored in the Redux state, not what is stored in localStorage. Tension: Updates to localStorage don't trigger React to rerender. Outcome: dispatch(logoutAuth());.

MATCHESSolution

Do not reset the entire API slice state during the mutation lifecycle; instead rely on the sendLogout trigger promise/unwrap (or on isSuccess without resetting) to run navigate("/") after the mutation succeeds.

MATCHESSolution

convert the object into the builder callback syntax — createSlice({ name, initialState, reducers: { /* case reducers here */ },. Tension: object syntax for `createSlice.extraReducers` has been deprecated. Outcome: builder => { builder.addCase(todoAdded, (state, action) => {}) }.

MATCHESSolution

resolve npm install @reduxjs/toolkit@^1.9.6 — in my Expo project. Tension: createSlice is not a function (it is undefined). Outcome: npm install @reduxjs/toolkit@^1.9.6.

MATCHESSolution

Move the `Auth()` invocation into a thunk action (or call it from the component) and have the reducer handle only state updates based on the thunk’s dispatched success/failure actions.

MATCHESSolution

Use `state.books = state.books.filter(...)` (ensuring the assignment happens) or prefer a mutating approach like `splice()` that directly updates the array in the reducer.

MATCHESSolution

Use the reducer exported by createSlice in configureStore; the store gets the initial state from that reducer

MATCHESSolution

Update the reducer logic to access into `action.payload.applicationUser` property. — Redux-Toolkit slice reducers. Tension: the reducer is accessing some `user` property that doesn't exist in the response object. Outcome: Mutate state directly.

MATCHESSolution

You don't need to use the same name for both. Tension: it also ships with a new `combineSlices` api. Outcome: in most cases you probably shouldn't deviate unless you have a reason.

MATCHESSolution

Add extraReducers/addMatchers for each mutation endpoint (addTour, editTour, removeTour) to update `state.tour` on `matchFulfilled`, or use RTK Query tags and invalidation so queries refetch and state stays in sync.

MATCHESSolution

The bundler needs to bridge those two formats. Tension: Slider becomes an object like { __esModule: true, default: function Slider() {} } instead of the `function Slider()` React expects. Outcome: React gets a Wrapper Object.
