AntiPattern

State-Change Side Effects Drift

unstable-side-effects-and-incomplete-wiring

Hooked side effects and event handlers drift from intended behavior when components rely on unstable dependencies or incomplete interaction wiring, causing onOpen to fire repeatedly or not at all, dropdown clicks to be swallowed, and UI state (e.g., single selection) to become inconsistent.

MATCHESSolution

you can use Zustand getters and optimistic update — multiple or rapid clicks could actually cause the updates to be executed but out of order. Tension: no optimistic update so u see that delay (lag) you said about.

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

subscribe to store changes to fire side-effect — What you can do is to subscribe to store changes. Tension: you will have to send the whole state of the store every time it changed. Outcome: use subscribe with selectors.

MATCHESSolution

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.

MATCHESSolution

Refactor so that hooks are called only inside the custom hook or at the component level, and return plain functions that do not call hooks (e.g., compute/set needed state without invoking hooks in the returned callback). Alternatively restructure the custom hook to expose non-hook handlers or move the hook invocation to component initialization and pass the resulting setters.

MATCHESSolution

They both have their own pros and cons — base it on your project requirements. Tension: If you have quite a complex application tree of deeply-nested components Recoil's uses atoms and selectors pattern. Outcome: If you prefer a more direct approach with Zustand your state is stored in a single store and is accessed and modified directly by your components.

MATCHESSolution

removing the `[state=open]:animate-in` from both `DialogPrimitive.Overlay` and `DialogPrimitive.Content` fixed the problem for me — Dialog box component in my React application using Shadcn UI. Tension: While this fixed the flickering issue, I'm wondering if there's a better or more elegant solution. Outcome: removed the animation-related classes from the DialogPrimitive.Content component.

MATCHESSolution

Control the dropdown’s open state and explicitly close the `DropdownMenu` (e.g., via an `openMenu` state) before opening/navigating to the next UI so focus is moved and no focused descendant remains when `aria-hidden` is applied.

MATCHESSolution

To make this work, you should not use nested triggers. — the tooltip dialog combo. Tension: It is also enough to keep the open state only for the dialog. Outcome: Reorganize the code as follows to make it work.

MATCHESSolution

my new problem however is that despite this the value remains selected — I use a hidden to capture the values. Tension: the inputs do actually respect the state changes. Outcome: the inputs do actually respect the state changes.

MATCHESSolution

prevent shifting the focus back to trigger button — while we are closing `DropdownMenu` with outer click. Tension: tooltip again, incorrectly. Outcome: e.preventDefault().

MATCHESSolution

Replace the custom components with HTML elements so the state updates work as expected

MATCHESSolution

Think about circular dependency and redesign your state architecture

MATCHESSolution

Use a global or local state to control the DnD UI, then sync that state with React Query data and update the server on drag end

MATCHESSolution

event.stopPropagation(); handleStatusChange(event); — onChange={(event) => {. Outcome: event.stopPropagation(); handleStatusChange(event);.

MATCHESSolution

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.

MATCHESSolution

Update the dropdown toggle logic to only close dropdown menus that are not ancestors of the clicked toggle, and ensure the correct toggle/close behavior for all nested levels.

MATCHESSolution

No ref to prevent redundant state updates — `setState` inside an observer callback that runs on every scroll event. Tension: React still processes the `setState` call even if the value is the same. Outcome: const lastIdRef = useRef(null);.

MATCHESSolution

Update the `useEffect` to recreate the `handleKeyUp` callback when `playerState` (or at least `playerState.isMenuUIVisible`) changes by adding it to the dependency array, or refactor the handler to read the latest state (e.g., via a ref) so it doesn’t rely on stale closure values.

MATCHESSolution

Trigger focus after readOnly updates—e.g., set a flag on double-click and call focus in a useEffect (or a callback) once readOnly is false.

MATCHESSolution

Call all hooks unconditionally at the top of the component (e.g., move useParams() above the ready/user checks) and only render conditional UI afterward; optionally use nested routes for subpages instead of relying on conditional logic.

MATCHESSolution

Use a ResizeObserver to watch for layout/size changes when the side-panel opens or closes, and re-run the checkPanelState logic on those resize events. Add a debounce to avoid excessive calls.

MATCHESSolution

it's worth considering if you need an effect here in the first place — if your inner dialog has an onOpen event you can tap into. Tension: as using that would be better to call your `onOpen` callback. Outcome: using that would be better to call your `onOpen` callback.

MATCHESSolution

Move the reset logic into a useEffect (or handle reset from the parent via props) so state updates occur as effects rather than during render. In the parent, toggle the reset flag (and optionally set it back to false after the update) to trigger the child's reset without causing continuous re-renders.

MATCHESSolution

Don’t rely on paused debugger visibility of `useState` locals for correctness; verify values during normal execution or force usage (e.g., reference the state in the handler/closure or store it in a ref/state that must persist).

MATCHESSolution

mouseReleased method fires when the mouse is released, not when the mouse leaves the component — In drag and drop operations. Outcome: just the normal behaviour.

MATCHESSolution

BuildHash controls when the panel re-renders. — s&box UI uses Razor (.razor files) paired with PanelComponent. Tension: Key patterns:. Outcome: StateHasChanged();.

MATCHESSolution

Keep menu screens and in-game overlays in separate input modes. — Startup/customization menus can force Mouse.Visibility = Visible and keep pointer events enabled. Tension: Startup/customization menus can force Mouse.Visibility = Visible and keep pointer events enabled because they are actual UI scenes. Outcome: Fix pattern:.

MATCHESSolution

Universal hook set for MCP behavioral activation. Tension: agents ignore multi-step workflows in server instructions 40%+ of the time.

MATCHESSolution

record that the side effect fired, check before firing again — awarding XP, delivering a notification, processing a queue item. Outcome: All three are instances of the same principle.
