Replace the rank-level family (useHasRankLevel + STAFF_LEVELS
constants + useIsRank) with a permission-driven family that reads
straight from the deployment's `permission_definitions` table — no
more hardcoded SecurityLevel/rank-id thresholds on the client. A new
rank in permission_ranks or a re-shuffling of permission_definitions
rank columns now propagates through the UI automatically.
Renderer-side wire shipped in companion commit
feat/react19-event-bus@159c5eb (UserPermissionsMapParser + Event,
SessionDataManager.getPermissionsSnapshot + USER_PERMISSIONS_UPDATED).
New public API in `useSessionSnapshots.ts`:
- useUserPermissions(): ReadonlyMap<string, number> — full map
- useHasPermission(key): boolean — > 0 ⇒ true
- usePermissionValue(key): number — raw 1/2 or 0
- useIsAmbassador() now aliases useHasPermission('acc_ambassador')
- useUserRank() kept for PRESENTATIONAL use only (badge, prefix,
prefix color) — documented as such in JSDoc; gating must use
useHasPermission.
Dropped:
- src/api/nitro/session/RankLevels.ts (STAFF_LEVELS constants)
- useHasRankLevel / useIsRank exports (rank-based gating)
11 consumer migrations, each mapped to the right
`permission_definitions.permission_key`:
- ToolbarView (mod-only chat-input button) → acc_supporttool
- ChooserWidgetView (room-object id column) → acc_supporttool
- CatalogClassicView (admin toggles) → acc_catalogfurni
- CatalogModernView (admin toggles) → acc_catalogfurni
- FurniEditorView (panel access) → acc_catalogfurni
- CalendarView (force-open day) → acc_calendar_force
- InfoStandWidgetFurniView (mod buildtools btn) → acc_anyroomowner
- AvatarInfoWidgetPetView (canPickUp) → acc_anyroomowner
- FurnitureMannequinView (controller mode) → acc_anyroomowner
- YouTubePlayerView (isMyRoom) → acc_anyroomowner
- NavigatorRoomInfoView 'settings' → acc_anyroomowner
- NavigatorRoomInfoView 'staff_pick' → acc_staff_pick
Test refresh:
- useUserRank still tested for the presentational shape.
- useHasPermission: true for non-zero, false for absent/zero.
- usePermissionValue: raw 1 / 2 / 0 (default).
- useUserPermissions: full map exposure.
- Runtime promote test: mutate the permissions map + dispatch
USER_PERMISSIONS_UPDATED, assert useHasPermission flips false→true.
Locks in the new reactive contract.
Mock unchanged (the test sets getPermissionsSnapshot via vi.mocked).
Verification: yarn typecheck clean, yarn lint:hooks clean, yarn test
214/214 (213 prior + 1 net new for useUserPermissions). Backward
compatible: older Arcturus deployments don't ship the map → empty
snapshot → every gate is false → mod UI hidden (safe default).
Drop the SecurityLevel-named family (useIsModerator / useIsAdmin /
useIsCommunity / useIsPlayerSupport / useHasSecurityLevel /
useUserSecurityLevel) in favour of a rank-based family tied to the
operator's actual `permission_ranks` rows in the Arcturus DB:
- `useUserRank()` returns `{ id, name, level, badge, prefix,
prefixColor }` derived from the snapshot. Powered by the renderer's
extended IUserDataSnapshot (companion commit 87e67d5 on
feat/react19-event-bus).
- `useHasRankLevel(min)` replaces useHasSecurityLevel; consumers
pass a `permission_ranks.level` threshold from the deployment.
- `useIsRank(name)` matches `permission_ranks.rank_name` exactly.
To avoid bare integers in widget bodies, added a deployment-scoped
constants file at `src/api/nitro/session/RankLevels.ts`:
export const STAFF_LEVELS = {
MEMBER: 1, SUPPORT: 4, MOD: 5, SUPER_MOD: 6, ADMIN: 7
};
A deployment that re-numbers `permission_ranks` only edits this file.
Migrated all 11 consumer reads (same set as the earlier session's
useIsModerator migration plus the audit catch): ToolbarView,
CatalogClassicView, CatalogModernView, ChooserWidgetView,
CalendarView, YouTubePlayerView, FurniEditorView,
InfoStandWidgetFurniView, AvatarInfoWidgetPetView,
FurnitureMannequinView, NavigatorRoomInfoView. The
NavigatorRoomInfoView `staff_pick` permission was previously
`securityLevel >= COMMUNITY (7)` via the renderer-enum wrapper —
ported to `useHasRankLevel(STAFF_LEVELS.ADMIN)` because in the
default seed level 7 is Administrator, which is the actual rank that
gets the `acc_anyroomowner`-style permissions for staff-picking.
Tests refreshed under `useSessionSnapshots.test.tsx`:
- useUserRank surfaces the full metadata block;
- useHasRankLevel does `>=` against the threshold;
- useIsRank exact-matches against rank_name;
- a runtime promote (snapshot mutation + SESSION_DATA_UPDATED
dispatch) flips the result, locking in the reactive contract.
Mock extended only minimally — kept the SecurityLevel enum class for
any consumer outside the dropped family that still imports it.
Verification: yarn typecheck clean, yarn lint:hooks clean, yarn test
213/213. The Arcturus-side composer change (UserPermissionsComposer
appending the 5 extra fields) is staged but UNCOMMITTED on Arcturus
main (which has unrelated WIP); the wire is backward-compatible so
the React client works against both pre- and post-extension
emulators.
Adds a reactive `useIsModerator()` derived from
`useUserDataSnapshot().securityLevel >= SecurityLevel.MODERATOR`
(mirrors the renderer-side getter at SessionDataManager.ts:684), and
migrates the six React component-body reads of
`GetSessionDataManager().isModerator`:
- ToolbarView (mod-only chat-input button)
- CatalogClassicView, CatalogModernView (admin toggles in catalog
header)
- ChooserWidgetView (room-object id column visibility)
- YouTubePlayerView (room-control affordance — hook moved above the
`if (!isOpen) return null` early return so the hook order stays
stable when the player opens/closes)
- CalendarView (mod-only "open all" affordance)
UX impact: any future promote/demote that flips
SESSION_DATA_UPDATED now re-renders the mod-only UI live, instead of
requiring an F5. Imperative call sites
(AvatarInfoUtilities.populate*, CanManipulateFurniture,
RoomChatHandler) still read the manager directly — they run at click
time, not in a React render, so reactivity has no upside there.
Five of the six call sites are top-level component-body reads (no
early-return interaction). YouTubePlayerView has an
`if (!isOpen) return null` below the hook list, so the hook had to
move ABOVE it; same shape as the recent CatalogPurchaseWidgetView and
CatalogItemGridWidgetView fixes.
Verification: yarn typecheck clean, yarn lint:hooks clean, yarn test
209/209.
Two follow-ups to the CatalogPurchaseWidgetView fix (6bf3366):
1. CatalogItemGridWidgetView had the same shape — four useCallback
declarations (handleDragStart / handleDragOver / handleDrop /
handleDragEnd) sat below an `if(!currentPage) return null` early
return. When currentPage flipped from null to a real page the hook
count jumped by 4 and React would have thrown "Rendered more hooks
than during the previous render" the moment any consumer rendered
the grid in admin mode. Moved the four useCallback declarations
above the early-return; their bodies are safe pre-load (only
currentPage?.offers is accessed inside handleDrop, optional-chained
already).
2. CI gate — the existing GitHub Actions workflow runs `yarn
typecheck` and `yarn test`, but NOT `yarn eslint`. That's why this
pattern slipped through twice in a row: ESLint flags it locally
but no PR check enforces it. Full `yarn eslint` emits ~900
pre-existing baseline errors (brace-style, indentation,
recommended TS rules — out of scope for this branch), so a blanket
step would always fail. Instead added a focused
`eslint.hooks.config.mjs` + `yarn lint:hooks` script that runs
ESLint with ONLY `react-hooks/rules-of-hooks: error`. Wired into
ci.yml between `typecheck` and `test`. The local repo now has
zero violations of the rule.
3. useSessionSnapshots.test.tsx — added eslint-disable-next-line
comments on the three lines that intentionally violate the rule
(they're the assertions that the broken pattern crashes). Without
the comments the new CI gate would fail on the regression-guard
suite.
Verification: yarn lint:hooks green, yarn typecheck clean, yarn test
209/209.
React reported "Rendered more hooks than during the previous render"
when CatalogPurchaseWidgetView transitioned from currentOffer=null to
a real offer: hook count jumped from 22 to 23 because the
useMemo/useEffect block for the builders-club placement state sat
*below* the `if(!currentOffer) return null` early-return on line 140.
On the first render it never ran; on the next render (offer loaded)
it did, and React's hook-call tracker flagged the divergence and
unmounted the component via the error boundary.
Fix: move the three builders-club hooks (useMemo builderPlaceableStatus,
useMemo buildersClubPlaceOneButtonStyle, useEffect interval) above the
early return. They already short-circuit cleanly when
isBuildersClubPlaceable is false — added a defensive `!currentOffer`
guard on the first useMemo and an explicit `!!currentOffer` clause on
the derived isBuildersClubPlaceable so the .product access stays safe
when offer is null. Behavior unchanged for the loaded-offer path; the
early-render path now runs the hooks but their bodies no-op.
Verification: yarn typecheck clean, yarn test 209/209.
Replaces every direct call to the deprecated useCatalog() shim with the
targeted filter(s) (useCatalogData / useCatalogUiState / useCatalogActions).
Each consumer now subscribes only to the slice it actually reads, which
restores React Compiler memoization and stops catalog-wide re-renders
whenever an unrelated key changes.
Removes the now-unused useCatalog shim from useCatalog.ts and the
shim-specific case in tests/useCatalog.filters.test.tsx. The "all four
hooks observe the same singleton" test becomes "all three filters", since
there is no shim left to compare against. useCatalogFavorites swaps its
internal useCatalog() call for useCatalogUiState() (currentType lives in
the UI slice).
Updates CLAUDE.md and docs/ARCHITECTURE.md to reflect that all 48
historical consumers are migrated and the shim is gone.
Vitest: 162/162 (was 163 — minus the deprecated-shim contract case).
Completes the useCatalog decomposition. After the previous commit
extracted the pure helpers, this one splits the singleton-via-useBetween
store into three slice-specific entry points and migrates a handful of
consumers as proof.
`src/hooks/catalog/useCatalog.ts`
- Internal `useCatalogState` → renamed to `useCatalogStore` and is no
longer exported. The full return shape is unchanged so callers that
still go through the shim see the exact same object.
- Three new exports built on top of the same `useBetween` instance:
- `useCatalogData()` — server-driven read-only slice (rootNode,
offersToNodes, currentPage, currentOffer, frontPageItems,
searchResult, roomPreviewer, isBusy, catalog localization
version, Builders Club counters + timers).
- `useCatalogUiState()` — UI ephemeral state + writers
(isVisible, pageId, previousPageId, currentType, activeNodes,
navigationHidden, purchaseOptions, catalogPlaceMultipleObjects,
plus every `set*` writer including the ones that mutate the
data slice on user-driven selection).
- `useCatalogActions()` — imperative operations only
(openCatalogByType, toggleCatalogByType, activateNode,
openPageBy{Id,Name,OfferId}, requestOfferToMover,
selectCatalogOffer, getNodeBy{Id,Name},
getBuilderFurniPlaceableStatus).
- `useCatalog` is kept as a deprecated shim that returns the full
historical surface, so the 48 existing consumers compile and run
unchanged.
Pilot consumer migrations (3 of 48):
- `CatalogBuildersClubStatusView` — Data (furni counters, seconds
timers) + UiState (currentType).
- `CatalogBreadcrumbView` — UiState (activeNodes) + Actions
(activateNode).
- `CatalogNavigationItemView` — UiState (currentType) + Actions
(activateNode).
Tests: `tests/useCatalog.filters.test.tsx` (5 cases).
`useBetween` is mocked via `vi.hoisted` so the four hooks share one
deterministic fake store — rendering the real `useCatalogStore`
would mount ~30 useState calls + open a fresh RoomPreviewer +
subscribe to a dozen renderer events, which is more than these
contract tests need.
- `useCatalogData` exposes exactly its read-only keys.
- `useCatalogUiState` exposes exactly its UI keys + setters.
- `useCatalogActions` exposes exactly its imperative ops (and
explicitly NOT data fields — proves no leak across slices).
- Singleton identity: callbacks read through the shim are `===` to
the ones read through the slices.
- Shim surface: the historical key set is still present so
un-migrated consumers don't silently break.
Suite: 163/163 (was 158/158). `yarn typecheck` green.

This commit drains the last field out of ICatalogOptions (clubGifts)
and deletes the interface — useCatalog no longer owns a catch-all
mutable object that downstream components stuff data into.
Two pieces:
1) New useNitroEventInvalidator(eventType, queryKey, accept?) — a
small companion to useNitroQuery for the case where the server
pushes the same event unprompted (e.g. ClubGiftInfoEvent fires
both as the response to GetClubGiftInfo and again after the user
claims a gift via SelectClubGiftComposer). It calls
queryClient.invalidateQueries() on each matching push so the
next render of any subscriber triggers a fresh queryFn.
2) New useClubGifts() — useNitroQuery on the ClubGiftInfoEvent
pair, paired with useNitroEventInvalidator so server-driven
pushes refresh the cache automatically. CatalogLayoutVipGiftsView
now consumes the query directly. The local optimistic
'giftsAvailable--' mutation (which side-effected the parser
object passed back to the catalog state!) is dropped — the
server's authoritative ClubGiftInfoEvent push is the single
source of truth via the invalidator.
useCatalog drops the matching listener + the GetClubGiftInfo dispatch
from the catalog-open effect. ICatalogOptions is now empty and
deleted; the catalogOptions / setCatalogOptions state + return-shape
field are removed from useCatalog along with the import.
MarketplacePostOfferView was both *the* fetcher and the listener for
MarketplaceConfigurationEvent — it dispatched
GetMarketplaceConfigurationMessageComposer from one effect when item
was set, then routed the response through setCatalogOptions.
useCatalog never touched the field; it was passing through catalogOptions
purely as a transport mechanism for this single component to talk to
itself. Replace with useMarketplaceConfiguration() — staleTime Infinity
(server-side constants for a session), enabled on item, single tidy
data path.
Drops marketplaceConfiguration from ICatalogOptions; with petPalettes
out too, ICatalogOptions is now just { clubGifts }. clubGifts is the
last one and needs invalidation (server pushes ClubGiftInfoEvent after
SelectClubGiftComposer) so it stays put until useNitroEventInvalidator
companion lands.
CatalogLayoutPetView previously read 'catalogOptions.petPalettes' (an
accumulating array of CatalogPetPalette objects keyed by breed) and,
on cache miss, dispatched GetSellablePetPalettesComposer(productData.type)
inline. useCatalog kept the matching SellablePetPalettesMessageEvent
listener that appended each new breed to the array (deduping by breed
identity).
Migrate the request/response pair to a TanStack query parameterized on
breed:
useSellablePetPalette(breed)
key: ['nitro', 'catalog', 'petPalette', breed]
request: () => new GetSellablePetPalettesComposer(breed)
parser: SellablePetPalettesMessageEvent
accept: event.getParser().productCode === breed
select: build a CatalogPetPalette from parser
enabled: !!breed (avoid spamming composers before currentOffer is set)
staleTime: Infinity
The view now derives breed from currentOffer.product.productData.type
and reads 'const { data: petPalette }'. The cache-miss-then-fetch
two-pass effect collapses into a single effect that runs once
petPalette resolves (or clears state when offer/petPalette aren't
ready).
Drops the matching listener from useCatalog, drops petPalettes from
ICatalogOptions, and removes the now-unused CatalogPetPalette /
SellablePetPalettesMessageEvent imports from useCatalog.
Two catalog layouts each fire 'new GetClubOffersMessageComposer(windowId)'
on mount and read parser.offers via HabboClubOffersMessageEvent:
- CatalogLayoutVipBuyView (windowId 1)
- CatalogLayoutBuildersClubBuyView (windowId 2 / 3, depending on
the addon variant)
Plus useCatalog used to also listen for HabboClubOffersMessageEvent and
stash the offers in 'catalogOptions.clubOffersByWindowId[windowId]' and
'catalogOptions.clubOffers' (the latter being a backward-compat alias
for windowId 1). Three listeners, three independent requests when all
mounted.
New useClubOffers(windowId) wraps the request/response pair as a
TanStack query keyed by '['nitro', 'catalog', 'clubOffers', windowId]'.
accept(): correlation-key filter (parser.windowId === windowId) so
the same multiplexed event doesn't satisfy the wrong query slot.
Both layouts now read 'const { data: offers = null } = useClubOffers(windowId)';
useCatalog drops the listener, ICatalogOptions drops the
clubOffers / clubOffersByWindowId fields and HabboClubOffersMessageEvent
no longer needs to be imported in useCatalog. The localization-refresh
effect that re-cloned both fields is also dropped — React Query owns
the cache now, and ClubOfferData has no localized strings anyway.
Four independent components used to send 'new CatalogGroupsComposer()'
on mount and listen for GuildMembershipsMessageEvent:
- useCatalog (writing into catalogOptions.groups)
- CatalogLayoutGuildForumView
- CatalogGuildSelectorWidgetView
- WiredSelectorUsersGroupView
- WiredConditionActorIsGroupMemberView
Each fired its own request and re-listened independently. With four
of them mounted in the wired-tools panel during a builder session,
the same packet went out four times.
New useUserGroups() hook wraps the request/response pair with
useNitroQuery (queryKey ['nitro', 'user', 'groups'], staleTime
Infinity — guild membership is session-stable). All four consumers
now read 'const { data: groups = [] } = useUserGroups()' and React
Query dedups: one composer at the first mount, all subsequent mounts
get the cached array.
Drops 'groups' from ICatalogOptions and the corresponding listener +
prev-state-merge from useCatalog — no remaining consumer reads it.
CatalogAdminContext exposes savePage / deletePage / saveOffer /
createOffer / deleteOffer as void-returning fire-and-forget composer
dispatches — they just call SendMessageComposer and let the server
push back later. The Offer/Page edit views were 'await action(data);
if(success) closeForm()' as if the actions returned Promise<boolean>,
but they don't return anything. tsgo flagged the truthiness check on
void.
Drop the await + truthiness — call the action, then close the form
unconditionally. This matches the actual behaviour: closeForm() ran
synchronously after the void anyway. A future PR that wants real
'wait for server confirmation' UX should refactor the context to
return Promise<boolean> (correlated to the response packet via the
pendingActionRef machinery already in place).
React 19 dropped the no-arg useRef overload — the type-only useRef<T>()
form (no initial value) is gone, every call must pass an initial value.
The codebase had 15 occurrences of useRef<HTMLDivElement>() (DOM ref
pattern) all flagged by tsgo as 'Expected 1 arguments, but got 0'.
Mechanical sweep to useRef<HTMLDivElement>(null) — no behavior change,
React still hands out a ref object with .current set to null at mount.
Net tsgo error count: 57 -> 42.
The catalog's gift wrapping configuration was loaded by an effect in
useCatalog that fired GetGiftWrappingConfigurationComposer every time
the catalog opened, with the response stuffed into a catalogOptions
slice via setState-in-effect. Migrating to a TanStack query gives us
caching/dedup/loading-state for free on this one-shot session-stable
loader.
- New useGiftConfiguration() hook in src/hooks/catalog/ wraps the
composer/parser pair with useNitroQuery and staleTime: Infinity
(the wrapping config never changes within a session).
- CatalogGiftView now reads from the query directly instead of via
catalogOptions; the useCatalog() call in that component is also
dropped (no other field was used).
- useCatalog drops the GiftWrappingConfigurationEvent listener and the
unconditional composer dispatch.
- ICatalogOptions loses the giftConfiguration? field — no remaining
consumer.
First step toward the docs/ARCHITECTURE.md next-PR item 'Migrate
useCatalog read-only fetches to useNitroQuery'. The clubGifts loader
will follow once useNitroEventInvalidator lands (clubGifts can be
push-updated by the server after SelectClubGiftComposer, so it needs
cache invalidation, not just a one-shot fetch).
Second concrete adoption of proposal #2 (first was OfferView).
Before
- A useState<RoomEntryData[]>([]) for availableRooms.
- A useMessageEvent<RoomAdPurchaseInfoEvent> handler that
set the state on each parser event.
- A useEffect on mount that dispatched two composers, one of which
was GetRoomAdPurchaseInfoComposer paired with the parser above.
After
- A single useNitroQuery call wires the request and parser as one
read-only query. The select extracts parser.rooms with a default
empty array.
- staleTime is 60s — opening the same panel within a minute reuses
the cached value; the composer is not re-dispatched. Useful here
because the user navigates between catalog tabs.
- The mount-only useEffect no longer dispatches the room-ad composer;
the second composer (GetUserEventCatsMessageComposer) stays where
it was — that one feeds useNavigator state and isn't a
request-response pair this component owns.
Why this file
- It was the cleanest pattern in the catalog tree: no correlation
keys, no conditional filter on the parser, no other writes to
availableRooms. The pure derive-from-event case useNitroQuery is
built for.
- The big god-hook useCatalog (1100 LOC) still owns most of the
catalog data layer; migrating that needs the data/uiState/actions
split first.
Verification
- yarn test: 49/49 still passing.
- yarn eslint on the touched file: 1 error (the pre-existing
set-state-in-effect on line 36, unchanged — baseline matches).
- The previous useMessageEvent import was removed cleanly.
Phase 1 of the refactor plan in docs/ARCHITECTURE.md.
Install
- yarn add @tanstack/react-query@5 @tanstack/react-query-devtools@5
- Both pinned to ^5 (matches React 19 peer requirement).
Wiring
- src/index.tsx: mounts QueryClientProvider above ErrorBoundary +
Suspense. Default config: staleTime=30s, retry=1,
refetchOnWindowFocus=false (chat client, not a data dashboard).
Adapter
- src/api/nitro-query/createNitroQuery.ts: replaces the previous
prototype that just threw. Exposes:
* useNitroQuery({ key, request, parser, select, timeoutMs })
— wraps TanStack's useQuery; queryFn awaits the parser response.
* awaitNitroResponse(...) — lower-level helper for imperative use
via queryClient.fetchQuery.
The Promise:
1. registers the parser via GetCommunication().registerMessageEvent
2. dispatches the composer via SendMessageComposer
3. resolves with select(event) on the first matching parser
4. rejects after timeoutMs (default 15s)
5. always cleans up the listener + timeout (cancel-safe).
Pilot
- src/components/catalog/views/targeted-offer/OfferView.tsx:
the previous useMessageEventState + manual useEffect-send pattern
becomes a single useNitroQuery call. staleTime:Infinity because the
targeted offer doesn't change during a session. Subsequent OfferView
remounts (e.g. opening/closing the dialog) now reuse the cached
payload — the GetTargetedOfferComposer is no longer re-sent each
time.
Verification
- yarn eslint on the four touched files: 1 pre-existing
no-redundant-type-constituents error (IMessageEvent resolves as `any`
in the local sandbox without the renderer SDK installed; matches the
12 other pre-existing instances of the same false positive).
- yarn tsc on the four touched files: clean (modulo the
project-wide TS2307 about @nitrots/nitro-renderer).
- The original prototype's "throw" guard is gone — useNitroQuery is now
callable.
Migration path (per docs/ARCHITECTURE.md)
- Next adoption targets (read-only fetches first): useCatalog's page
data, useInventoryFurni's bot listing, Navigator search results,
Marketplace listings.
- Push messages (server-pushed events the client doesn't request)
keep using useNitroEventState / useMessageEventState — they're
subscriptions, not requests.
https://claude.ai/code/session_01GrR87LAqnAEyKG2ZbmQt5Q
Introduce the building block for reducing the state-from-event
boilerplate that pervades the codebase:
// Before
const [foo, setFoo] = useState(initial);
useNitroEvent(SOME_EVENT, e => setFoo(e.payload));
// After
const foo = useNitroEventState(SOME_EVENT, e => e.payload, initial);
Implementation notes:
- src/hooks/events/useNitroEventState.ts wraps useNitroEvent so the
selector closure can use up-to-date surrounding values (captured in
a ref refreshed in commit via useLayoutEffect) without forcing a
re-subscription on every render. Listener is registered once and
always reads the latest selector.
- src/hooks/events/useMessageEventState.ts is the mirror for
useMessageEvent (server message channel — request/response composers
and push parsers).
- Both pass the new react-hooks v7 rules cleanly (in particular the
strict react-hooks/refs that forbids ref mutation during render).
- Re-exported from src/hooks/events/index.ts so callers reach them
via the existing `from '../../hooks'` import path.
Pilot adoption (1 site) to demonstrate the pattern:
- src/components/catalog/views/targeted-offer/OfferView.tsx:
the offer state was a clean derive-from-event case
(setOffer(parser.data) on TargetedOfferEvent, no other writes).
Replaced with a single useMessageEventState call using the optional
chain `evt.getParser()?.data ?? null` as selector. Removes the
useState pair and the explicit subscription block.
Honest scope note:
A broader sweep is intentionally NOT done. Most existing event
subscriptions in this codebase are multi-state updates, state
machines, conditional filters ("skip if not my id"), or have side
effects mixed in (notifications, redirects). Forcing those into
useNitroEventState would lose information and risk regressions in
behavior the lint won't catch. Adoption should happen organically
when contributors see a clean derive-from-event case, not as a
mechanical replace-all.
https://claude.ai/code/session_01GrR87LAqnAEyKG2ZbmQt5Q
Fix only the cases that are unambiguous anti-patterns; leave the
event-driven setState patterns (useNitroEvent / useMessageEvent
subscriptions, async fetches with cleanup) alone since they're
legitimate in this architecture.
- src/components/catalog/views/catalog-header/CatalogHeaderView.tsx:
displayImageUrl was pure-derived from imageUrl. Drop the useState +
useEffect entirely; compute in render.
- src/components/navigator/views/NavigatorRoomCreatorView.tsx:
the maxVisitors list (10..100 step 10) and roomModels/selectedModel
came from static config; convert to module-level MAX_VISITORS_LIST
constant + useState lazy initializers. Removes 2 init effects.
setCategory(categories[0].id) is left as-is because categories
arrives async from a hook.
- src/components/login/LoginView.tsx:
Replace useEffect(() => setLocalError(null), [step]) with the
React-recommended "track previous prop" render-time reset:
if(prevStep !== step) { setPrevStep(step); setLocalError(null); }
Same observable behavior, no extra render.
- src/components/room/widgets/choosers/ChooserWidgetView.tsx:
Wrap the selectItem callback prop call in useEffectEvent so a
parent re-render that changes selectItem identity doesn't
re-fire the visualizer side-effects.
Net: 4 fewer set-state-in-effect violations; behavior preserved.
The remaining ~328 violations across the codebase are predominantly
legitimate event-bus / async-fetch patterns and need per-case
review with running app, not a sweep.
https://claude.ai/code/session_01GrR87LAqnAEyKG2ZbmQt5Q
Run eslint --fix across src/ to clear ~1900 mechanical lint errors
surfaced by the @typescript-eslint v8 + react-hooks v7 + react-compiler
upgrade in the React 19 modernization PR.
Issues fixed automatically:
- brace-style (Allman): try/catch one-liners reformatted to multi-line
- indent: tab-vs-space and depth corrections
- semi: missing trailing semicolons
- no-trailing-spaces
No semantic changes. Remaining 701 errors are real-code issues
(set-state-in-effect, rules-of-hooks, no-unsafe-* type checks) that
need manual per-file review.
https://claude.ai/code/session_01GrR87LAqnAEyKG2ZbmQt5Q
Adopt React 19 idioms across the codebase. The runtime was already on
react@19.2.5 but no React 19 APIs were in use.
- forwardRef -> ref-as-prop in 7 layout/component files
(NitroInput/Button/ItemCountBadge/Card×5/InfiniteGridItem,
ToolbarItemView, AvatarEditorIcon)
- <Ctx.Provider> -> <Ctx> in 6 contexts (CatalogAdmin, FloorplanEditor,
UiSettings, GridContext, NitroCardContext, NitroCardAccordionContext)
- Native <script> hoisting for Turnstile, ExternalPluginLoader, GoogleAdsView
(React 19 dedupes by src; removes manual document.head.appendChild +
module-level promise caches)
- React Compiler enabled at build time via babel-plugin-react-compiler
in vite.config.mjs (target: '19'), plus eslint-plugin-react-compiler
in lint mode
- Global <ErrorBoundary> + <Suspense> in src/index.tsx using
react-error-boundary, with LoadingView as fallback
- BackgroundsView migrated to use(promise) as a demonstrator pattern
for Suspense-driven config loading
- ESLint react setting bumped 18.3.1 -> 19.2; legacy
@typescript-eslint/ban-types replaced with no-restricted-types
(the old rule was removed in @typescript-eslint v8)
- Refresh public/configuration/{asset-loader,bootstrap}.js to match
current write-asset-loader.mjs output
Phase 3 (login forms -> useActionState/useFormStatus) deferred:
LoginView is 1623 lines with lockout + Turnstile + heartbeat

- XSS fix: Created SanitizeHtml.ts utility using DOMPurify (already in package.json but never used). Wrapped all 21 dangerouslySetInnerHTML calls in catalog views with SanitizeHtml() — only allows safe tags (b, i, u, br, span, div, p, a, strong, em, img)
- Race condition fix: Added 10-second timeout fallbacks on purchase flags in CatalogPurchaseWidgetView and CatalogGiftView so the flag auto-resets even if the server never responds
- Modern card-based layout with vertical icon rail, breadcrumb nav, inline search
- Admin mode: edit/create/delete pages and offers, drag & drop reorder via HK API
- Favorites system: heart on furni, star on pages, localStorage persistence
- Redesigned product card with price pills, dynamic quantity spinner
- Upgraded trophies (filter tabs, parchment textarea), pets (breed/color flow),
custom prefix (dynamic color boxes)
