AntiPattern

Async Thunk Promise Loss

async-thunk-promise-not-returned

Thunk actions often call request helpers but fail to return the underlying fetch/axios promise (or misplace baseQuery options), so createAsyncThunk never resolves correctly and downstream state updates, typing, and auth flows break unpredictably.

Initialize auth state to an indeterminate value (e.g., `undefined`) and render/loading or avoid redirect until `fetchCurrentUser` completes. After the async auth check, set `user` to either a valid user or null so the route guard redirects only when authentication is confirmed.

MATCHESSolution

Use the `persist` middleware to handle rehydration and remove any manual `AsyncStorage.getItem()`/store-restoring logic; define actions normally (e.g., `addTodo`, `removeTodo`, `toggleTodo`) and rely on `persist` to restore `todos` automatically.

MATCHESSolution

You should really use tag validation to trigger your query endpoints to refetch upon any successful mutation. — onSuccess: async () => { await queryClient.invalidateQueries({ queryKey: ["vehicle.getVehiclesWithMakes"],. Tension: Both are less than ideal. Outcome: await queryClient.invalidateQueries({ queryKey: ["vehicle.getVehiclesWithMakes"], // <-- invalidates tag key });.

MATCHESSolution

handle a scenario when the code is fine but backend went offline — prefetching data with usePrefetchQuery. Tension: prefetch works.

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

Update to pass the fetching function as the mutation's `mutationFn` property. — `const { mutate } = useMutation({ mutationFn: (title) => axios.post("/api/posts/addPost", { title }),. Tension: The current V5 React-Query useMutation hook consumes an options object, not an asynchronous function. Outcome: const { mutate } = useMutation({ mutationFn: (title) => axios.post("/api/posts/addPost", { title }), onSuccess: (data) => { console.log('Post added successfully:', data); }, onError: (error) => { console.error('Error adding post:', error); }, });.

MATCHESSolution

Mock axios.get and await the assertion with waitFor()

MATCHESSolution

myEndpoint must return a Promise — Please note, that above method is synchronous just to check if that makes difference, but it is not. Tension: my template is keep displaying "Loading..".

MATCHESSolution

Use fetch instead of Axios

MATCHESSolution

If you convert all operations to perform asynchronously (using `aiosqlite`) , the issue will be mitigated. — When a route in FastAPI is listed as asynchronous (`async def`). Tension: that doesn't fully solve the inherent single writer problem of Sqlite. Outcome: Here's a fully operational update of the FastAPI server logic:.

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

Fetch the token with proper `await` (assign the resolved token value) and ensure the middleware pauses until the token is retrieved before allowing RTK-Query to continue. Also unconditionally `return next(action)` so middleware chaining and timing behave correctly.

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

Move `useSQLiteContext` to the React component, obtain the SQLite DB instance there, and pass the DB instance (or data) into the thunk as an argument. Ensure the thunk action payload contains only serializable data.

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

implementing this retry behavior all over the place — axiosInstance.js. Tension: handle the retry logic. Outcome: you could try using a response interceptor to abstract and handle the retry logic.

MATCHESSolution

Wrap `fetchBaseQuery` with a custom async base query inside `retry`, inspect the result, and call `retry.fail(result.error)` when `result.error?.status === 401` to prevent further retry attempts.

MATCHESSolution

An async function was passed to useActionState.

MATCHESSolution

Wrap AuthService.login() in a Promise and resolve it from the callback

MATCHESSolution

Define the payloadCreator with only the thunkApi argument: use `async (_, { rejectWithValue }) => { ... }` or `async ({ rejectWithValue }) => { ... }` style as appropriate, and dispatch the thunk without any argument.

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

Use myAsyncAction.fulfilled as the listener actionCreator and prepend listenerMiddleware.middleware in configureStore

MATCHESSolution

const { data } = await thunkApi.dispatch( userApi.endpoints.login.initiate(credentials); );. Tension: I want to use `fetchBaseQuery` in the API call. Outcome: You can initiate an endpoint directly.

MATCHESSolution

Or you can use `async/await` and `try/catch` — createAsyncThunk. Outcome: return data.

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

Update the `login` Thunk to catch and handle any fetching errors/issues. Tension: handle Promise rejections and errors better. Outcome: return a rejection value (typically the error or error message).

MATCHESSolution

`nock@beta` support for `fetch` — Node 18+: make nock work native fetch. Tension: We have introduced experimental support for `fetch`.

MATCHESSolution

You forget to return the `fetch()` promise in the `requestRobots` thunk. Tension: it is giving only REQUEST_ROBOTS_PENDING and for other action when i run npm test it is giving undefined. Outcome: return fetch('https://jsonplaceholder.typicode.com/users').

MATCHESSolution

Use React async state management (e.g., `useAsync` or `useEffect` + `useState`) to await `currentSession()`, render a loading UI while pending, and only compute `isGroupOne` from the resolved array (e.g., `groups.some(...)`) after the Promise resolves.
