AntiPattern

Lifecycle-Aware Async Cleanup

lifecycle-ignored-async-effects

Component or object lifetime gets ignored when async tasks/effects are started, so work keeps running after destruction or is cut off mid-play; frame loops and performance suffer unless tasks and effects are tied to lifecycle-owned cancellation/finishing.

MATCHESSolution

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

MATCHESSolution

const usePermissionsStoreAsync = hook(usePermissionsStore, /*suspense*/false); — const YourComponent = () => {. Tension: if (userPermissions.isLoading) { return Loading... ; } if (userPermissions.error) { return An error occurred ; }. Outcome: Try Leo Query. It handle's async data for Zustand.

MATCHESSolution

Create/move the React.lazy import initialization so it isn’t executed on every render (e.g., place the lazy call in the same component as Suspense) to ensure the import is stable and doesn’t trigger repeated re-renders.

MATCHESSolution

Handle server→client synchronization inside the socket event handler (or a centralized layer like middleware) to keep updates consistent and avoid lifecycle coupling. Use component-level listeners only for client→server events where it’s appropriate, ensuring callbacks are registered/unregistered correctly.

MATCHESSolution

rendering the rows as a non complex component like a spinner or something — my laggy components were loading in as i scrolled etc. Tension: excessive blanking of the page. Outcome: using useEffect to determine if it is fully rendered, you can resolve most of the major blanking issues.

MATCHESSolution

Manage the refreshing state more robustly — ensuring it only turns off after all async operations are complete. Tension: remove the arbitrary timeout. Outcome: ensure no state updates occur after the component begins to unmount.

MATCHESSolution

Wrap you components that rely on React Query data — React Query data. Outcome: with Suspense and HydrationBoundary.

MATCHESSolution

single worker running async loop. Outcome: So you have a single worker running async loop and you block that loop.

MATCHESSolution

Move the persistence/cleanup logic into code that runs at the end of the background task (or otherwise extend lifecycle explicitly for the background task), rather than relying on the request-scoped `asynccontextmanager` teardown for those updates.

MATCHESSolution

Change the engine async fixture from session scope to function scope (remove scope="session") so all async fixtures/tests run on the same event loop, preventing the cross-loop Future/Task error.

MATCHESSolution

Using `asyncio.sleep()` in a loop is perfectly fine. Tension: every time you `await` the sleep, you effectively yield control back to the event loop. Outcome: calling `asyncio.sleep(0)` does not sleep at all, but only yields control back to the event loop.

MATCHESSolution

any time you have an I/O bound process with lots of idle time — waiting for user input, waiting for a TLS handshake. Tension: wrapping it in an async task can let other code run.

MATCHESSolution

bound it with a "progress ceiling" — a process emitting bytes but making NO semantic progress. Tension: a process emitting bytes but making NO semantic progress (livelock) would be shielded forever. Outcome: re-arms recovery after a long no-progress window even while bytes flow.

MATCHESSolution

Thread a second, lower-level liveness signal into the classifier — the timestamp of the last raw stdout byte from the child. Tension: Dead socket = no bytes = livenessAge grows = still aborts (correct). Alive-but-quiet = bytes flowing = livenessAge fresh = NOT aborted.

MATCHESSolution

An async function was passed to useActionState.

MATCHESSolution

Avoid running multiple DB operations concurrently on the same session by removing asyncio.gather and iterating sequentially, and/or use an async_scoped_session so each task uses its own session.

MATCHESSolution

future.cancel(true); — httpHardTimeoutScheduler.schedule(() -> {. Tension: if (!future.isDone() && !future.isCancelled()). Outcome: keep your latency low on your side of the wire.

MATCHESSolution

Use Component.Task (TaskSource) for all async work inside components — inside components. Tension: it auto-cancels when the component is destroyed.

MATCHESSolution

Add TemporaryEffect to GameObjects that should auto-destroy after effects finish — In the scene editor: add TemporaryEffect component to your effect prefab. Outcome: BecomeOrphan = true: if parent is destroyed, detach and finish playing.

MATCHESSolution

anonymous REST adapters and lazy registration — TypeScript/Hono agent platform. Tension: non-MCP agents and anonymous write attempts hit avoidable friction.

MATCHESSolution

CollectSyncState() iterates all components, finds [Sync] properties without [Property], serializes them to JSON — in SaveSystem.cs. Tension: Use JSON serialization first, with a ByteStream/BytePack fallback for types that don't serialize cleanly to JSON. Outcome: RestoreSyncState() is called before RestoreNetworkOwnership() in the Load path.

MATCHESSolution

Capture a baseline in `ISceneLoadingEvents.OnLoad` — after `await Task.Yield()` to ensure all objects are spawned. Outcome: Use static fields to persist the baseline across `Game.ChangeScene()` calls.

MATCHESSolution

Use a two-level system: `ScheduleBase` (a sequence of tasks with a `ShouldCancel()` interrupt check) and `TaskBase` (a single atomic action with `OnStart/OnUpdate/OnEnd`). — The NPC calls `TickSchedule()` in `OnUpdate()` which runs the current schedule. Tension: When a task returns `Success`, the schedule advances to the next task. When `ShouldCancel()` returns true, the schedule returns `Interrupted` and the NPC can select a new schedule. Outcome: Built-in tasks: MoveTo, LookAt, Wait, Say, FireWeapon, PickUpProp, DropProp.

MATCHESSolution

CancellationTokenSource pattern allows cancelling mid-reload — In `OnReloadStart`. Tension: when switching weapons or firing. Outcome: cancel any existing reload, create a new CTS, set `isReloading = true`, then `await ReloadAsync(token)`.

MATCHESSolution

Count by iterating only the player's list. Tension: pruning destroyed objects lazily during the count. Outcome: no separate cleanup pass needed.

MATCHESSolution

Set expire_on_commit=False on the async_sessionmaker — after commit. Tension: Or use await session.refresh(obj, ["relationship_name"]) after commit. Or eagerly load all needed relationships BEFORE commit using selectinload() or joinedload(). Outcome: attributes retain their in-memory values after commit.

MATCHESSolution

Cache in OnAwake — Key s&box performance patterns from the optimizer skill:. Tension: GetComponent every frame. Outcome: Physics work in OnFixedUpdate.

MATCHESSolution

Resolved activity IDs to visible renderer IDs before queueing pulses — pulse-only animation. Outcome: paused the renderer when idle.

MATCHESSolution

Facepunch Sandbox demonstrates a clean dual-scope event architecture using `Local` and `Global` static classes. Tension: Difficulty implementing cancellable events.

MATCHESSolution

Record original scene objects on startup — CleanupSystem Component. Tension: Efficient batch destruction.
