Button may be clickable when it should be disabled in onButtonClick

PERTAIN_TOProblem

My `HomePage.jsx` looks like this. Tension: The local isLoading variable is not suitable for storing the data loading state. Outcome: you need to check your backend code for fetching.

PERTAIN_TOProblem

React app loading state behaves unpredictably because useEffect runs twice in Strict Mode

PERTAIN_TOSolution

Use a cleanup function to clear the timeout, or simulate latency with Chrome DevTools throttling or MSW delay instead

PERTAIN_TOProblem

Audio toggle in Next.js is unreliable; it plays the first time but doesn't always pause or resume

PERTAIN_TOSolution

Use useRef instead of a root reference and call play() and pause() through audioRef.current

PERTAIN_TOSolution

The only thing that comes into my mind is a higher order component. — Once you want to have the ability to switch colors dynamically based on the dark or light mode value in your store. Tension: But this has to be done on each and every component / screen again. Outcome: Something like `withStyles()` that you can wrap around your component.

PERTAIN_TOProblem

React throws "Invalid hook call" when Zustand hooks are accessed via an Inversify-injected service (TypeScript) outside of a React component.

PERTAIN_TOSolution

Guard `localStorage` access with a client-only check (e.g., `typeof window !== 'undefined'` / run only in a client component) and initialize the Zustand store once on mount; optionally delay rendering of cart UI until initialization completes to avoid showing `0` temporarily.

PERTAIN_TOProblem

Both `onServerCode` and `onServerRecommendation` have a stale closure over the initial `projectIdStorage` state — socket.on("server_recommendation", onServerRecommendation); socket.on("server_code", onServerCode);. Tension: the server event handlers have the current project id value. Outcome: Update the `useEffect` hook to use a dependency on the `projectIdStorage` value.

PERTAIN_TOSolution

Update the `useEffect` hook to use a dependency on the `projectIdStorage` value — const projectIdStorage = useProjectStore((state) => state.projectIdStorage);. Tension: Both `onServerCode` and `onServerRecommendation` have a stale closure over the initial `projectIdStorage` state. Outcome: so that the server event handlers have the current project id value.

PERTAIN_TOSolution

Use get() inside the store creator to read current state, and call useCart.getState() only on the store hook instance

PERTAIN_TOSolution

Make both select inputs controlled components by binding their value to the zustand language state (using `value={language}`) and updating the store on change via the store `set`/action, so both selects re-render and stay in sync.

PERTAIN_TOProblem

A TypeScript error occurs when using Zustand's persist middleware with a custom StateCreator, stating that a StateCreator argument is not assignable to the expected StateCreator type due to mismatched $$storeMutators typing.

PERTAIN_TOProblem

Button may be clickable when it should be disabled in onButtonClick

PERTAIN_TOSolution

Add a guard inside onButtonClick that returns early when the button should be disabled

PERTAIN_TOProblem

You might be breaking the Rules of Hooks — useOutput(outputId, id, flowName)[1](output);. Tension: inside a function and this is not possible inside a function. Outcome: you need to initialize inside a componenet.

PERTAIN_TOProblem

After migrating to React 18, dynamically importing a language-specific component with React.lazy based on a zustand state variable causes the component to infinitely render/loading.

PERTAIN_TORootCause

I can't use my showError function here. Outcome: I create a global error store.

PERTAIN_TOProblem

I can't use my showError function here — I have a function `showError` that I am using through my react application. Outcome: How to show my error to the user.

PERTAIN_TOProblem

I don't have an access what happens intern in my store — If error occurs the items are an empty array. Tension: I don't have an access what happens intern in my store. Outcome: If error occurs the items are an empty array.

PERTAIN_TOSolution

I create a global error store. — I add setError in the catch block of my functions. Tension: I often use function names as scopes. Outcome: Then I can access the error msg in my components like this.

PERTAIN_TOProblem

Error: Cannot find module '../lightningcss.win32-x64-msvc.node' — failed to load config from C:\Users\user\Desktop\sann\ERP\vite.config.ts. Tension: error when starting dev server. Outcome: I tried all the solutions on the internet but the problem remained the same.

PERTAIN_TOSolution

TailwindCSS requires at least Node.js v20 to run — Knowing that I use Vite. Tension: LightningCSS will work. Outcome: Install the latest Microsoft Visual C++ Redistributable version.

PERTAIN_TOSolution

OK i added — package.json. Tension: not sure if it right soultion. Outcome: "overrides": { "react": "^19.0.0", "react-dom": "^19.0.0" }.

PERTAIN_TOProblem

In a React Hook Form + Zod multi-step form, custom validation logic in `refine()`/`superRefine()` was not being triggered, even when the condition should have passed.

PERTAIN_TOProblem

The Shadcn Form page crashes with a TypeError: Cannot destructure property 'getFieldState' of 'useFormContext(...)' as it is null when rendering the form fields.

PERTAIN_TOSolution

Import `Form` (and related components like `FormField`, `FormItem`, etc.) from `@/components/ui/form` instead of `react-hook-form`, so the Shadcn components receive the correct `FormProvider` context.

PERTAIN_TOProblem

No import alias found in your tsconfig.json file. — I get the error: No import alias found in your tsconfig.json file. Tension: I've set up my tsconfig.json file according to the Shadcn setup docs, so I'm not sure what's going wrong. Outcome: Create a `jsconfig.json` file with the following content:.

PERTAIN_TOSolution

Create a `jsconfig.json` file with the following content: — I'm following the Shadcn docs to set up vite react app project. Tension: No import alias found in your tsconfig.json file. Outcome: { "compilerOptions": { "baseUrl": "./", "paths": { "@/*": ["src/*"] } } }.

PERTAIN_TOProblem

switching the input from uncontrolled to controlled — If I don’t set a defaultValue for the number input. Outcome: use a modified, "controlled" version of the `Input` component by passing a default `value` to the underlying ``.

PERTAIN_TOSolution

You can use `coerce` to parse the value into a `number` — with react-hook-form, Zod, and ShadCN UI. Tension: This way you don't have to define a default value either. Outcome: passing a default `value` to the underlying ``.

PERTAIN_TOProblem

npm fails to install react-hook-form because its peer dependency on React does not match the project’s installed React version (React 19 RC).

PERTAIN_TOProblem

Submitting the form (clicking a submit button) does not trigger the onSubmit handler wrapped by react-hook-form's handleSubmit. The component shows no visible errors.

PERTAIN_TOProblem

if I would place these in the array, they would appear several times — display my Zod validation error messages using the `` and `` components from Shadcn/ui. Tension: these in the array, they would appear several times.

PERTAIN_TOSolution

Tension: if I would place these in the array, they would appear several times.

PERTAIN_TOSolution

parse.error.flatten().fieldErrors — Nextjs server action with zod validation. Tension: hard to return errors and show them in the UI. Outcome: form.setError(error.field, { message: error.message });.

PERTAIN_TOSolution

`handleSubmit` will preventDefault and receive the form data if form validation is successful. Tension: you don't need ref. Outcome: you can just pass your server action in `handleSubmit`.

PERTAIN_TOProblem

Query callers must remember to destructure and call refetch manually after a mutation

PERTAIN_TOSolution

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 });.

PERTAIN_TOProblem

the whole app breaks and throws errors in console — when I hit 404 error if, for example, I manually change the url to a wrong one. Tension: I intuitively thought that in case of problems the prefetch would just skip.

PERTAIN_TOSolution

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

PERTAIN_TOSolution

With useQuery you have an initialData ! — useQuery({ queryFn: () => getTodos(), queryKey: todoKeys.lists(), initialData: [] }). Tension: your data will not be undefined. Outcome: With this your data will not be undefined.

PERTAIN_TOSolution

I try putting a setName(data.name) inside a useEffect that runs only when "isLoading" changes, and it works — edit/change the "name" retrieved by the query. Tension: I would think there is a better and more clean way to do it. Outcome: use a `useEffect` hook to "synchronize" a React state to an external source.

PERTAIN_TOProblem

Type '(title: any) => Promise<AxiosResponse<any, any>>' has no properties in common with type 'UseMutationOptions<unknown, Error, void, unknown>' — The problem occured at line 13: `async (title) => await axios.post("/api/posts/addPost", { title });`. Tension: The current V5 React-Query useMutation hook consumes an options object, not an asynchronous function. Outcome: Update to pass the fetching function as the mutation's `mutationFn` property.

PERTAIN_TOSolution

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); }, });.
