Map Image Overlays and State Restoration #461
Conversation
- Add `imageOverlays` to `MapData` state and `MapDataProvider`. - Implement `ImageOverlayLayer` component for rendering and positioning images on Mapbox. - Add "Place on Map" button to `UserMessage` for image attachments. - Implement map state restoration logic by parsing the latest 'data' message in `app/search/[id]/page.tsx`. - Update `updateDrawingContext` server action to persist `imageOverlays`. - Fix redundant `MapDataProvider` instances in `Chat.tsx` that were shadowing state. - Ensure proper cleanup of Mapbox resources and React roots.

This introduces a solid end-to-end overlay feature, but there are a few high-impact issues around persistence frequency and Mapbox/React resource lifecycle. The biggest concern is unthrottled updateDrawingContext calls (likely many DB writes during marker drag) and leaking createRoot() trees / Mapbox load listeners in ImageOverlayLayer. State restoration should also normalize/whitelist parsed JSON to avoid shape drift across older chats and prevent undefined state fields from propagating.
Additional notes (1)
- Security |
app/search/[id]/page.tsx:62-62
Persisted state restoration parseslatestDataMessage.contentand passes it directly asinitialData. If older chats contain different shapes (e.g., onlydrawnFeatures, noimageOverlays, or different keys), the provider may start with missing defaults. Also,JSON.parsehere is a trust boundary: even if it’s your own data, you should minimally validate shape to avoid runtime crashes deeper in the app.
At minimum, normalize the subset you care about (arrays + cameraState) and ignore unknown keys.
Summary of changes
What changed
✅ Map state restoration on chat load
app/search/[id]/page.tsxnow scans DB messages for the most recent message withrole === 'data', parses its JSON, and passes it intoMapDataProviderviainitialData.
✅ Removed redundant providers (fixes state shadowing)
components/chat.tsxno longer wraps mobile/desktop layouts with nestedMapDataProvider, relying on the page-level provider instead.
✅ Added persisted image overlay state
components/map/map-data-context.tsxintroducesImageOverlayand addsimageOverlaystoMapData.MapDataProvidernow acceptsinitialData?: MapDataand initializes state from it.
✅ Render + manipulate overlays on Mapbox
- New
components/map/image-overlay-layer.tsxcreates a Mapboximagesource + raster layer per overlay, syncs coordinates/opacity, and adds draggable corner markers + a delete UI in drawing mode. components/map/mapbox-map.tsxrenders anImageOverlayLayerfor each entry inmapData.imageOverlays.
✅ UX: “Place on Map” for image attachments
components/user-message.tsxadds a hover button that creates a new overlay from the current map bounds and switches to drawing mode.
✅ Persist overlays server-side
lib/actions/chat.tsupdatesupdateDrawingContextsignature to accept optionalimageOverlaysalongsidedrawnFeaturesandcameraState.

There was a problem hiding this comment.
MapDataProvider initializes state from initialData verbatim, which can leave drawnFeatures, markers, and imageOverlays as undefined depending on what the persisted payload contains. You partially work around this elsewhere with || [], but leaving the canonical state shape inconsistent tends to create subtle bugs (e.g., code that maps without guarding, or merge logic that assumes arrays exist).
Because initialData comes from JSON.parse, it’s especially important to normalize defaults at the boundary.
Suggestion
Normalize initialData into a full MapData object with array defaults rather than storing it raw.
For example:
export const MapDataProvider: React.FC<{ children: ReactNode; initialData?: MapData }> = ({ children, initialData }) => {
const normalized: MapData = {
drawnFeatures: [],
markers: [],
imageOverlays: [],
...initialData,
drawnFeatures: initialData?.drawnFeatures ?? [],
markers: initialData?.markers ?? [],
imageOverlays: initialData?.imageOverlays ?? [],
}
const [mapData, setMapData] = useState<MapData>(normalized)

There was a problem hiding this comment.
The server action is now triggered for any change to drawnFeatures/imageOverlays and requires cameraState. Two correctness concerns:
mapData.drawnFeatures || mapData.imageOverlayswill be truthy even when both are empty arrays (because[]is truthy), which can cause unnecessary writes on initialization.- On rapid marker drags, you’ll call
updateDrawingContexton every intermediate state, likely creating manydatamessages and hammering the server/DB.
This should be debounced/throttled and should distinguish “data actually changed” from “arrays exist”.
Suggestion
Debounce persistence and tighten the condition so it only runs when there is meaningful content to persist.
Example approach:
- Compute counts:
const hasMapEdits = (mapData.drawnFeatures?.length ?? 0) > 0 || (mapData.imageOverlays?.length ?? 0) > 0 - Debounce the call (e.g., 300–800ms) and cancel on unmount.
Pseudo-code:
useEffect(() => {
if (!id || !mapData.cameraState) return
const hasMapEdits = (mapData.drawnFeatures?.length ?? 0) > 0 || (mapData.imageOverlays?.length ?? 0) > 0
if (!hasMapEdits) return
const t = setTimeout(() => {

deleteRootRef is typed as any and never unmounted. Because you create a React root inside a Mapbox marker element, you should call root.unmount() during cleanup; otherwise you risk leaking React trees and event handlers when toggling drawing mode, changing overlay coordinates, or unmounting the layer.
Also, you remove the marker element in cleanup but don’t clear deleteRootRef.current, which makes repeated toggles harder to reason about.
Suggestion
Avoid any and always unmount the React root you create.
Suggested changes:
- Type:
const deleteRootRef = useRef<import('react-dom/client').Root | null>(null) - Cleanup:
return () => {
markersRef.current.forEach(m => m.remove())
markersRef.current = []
deleteMarkerRef.current?.remove()
deleteMarkerRef.current = null
deleteRootRef.current?.unmount()
deleteRootRef.current = null

The effect that adds the Mapbox source/layer subscribes to map.on('load', onMapLoad) when style isn’t loaded, but it never unregisters the listener. If the component unmounts before load fires, the handler can still run later and attempt to add sources/layers for an overlay that no longer exists.
You should call map.off('load', onMapLoad) in cleanup when you register it.
Suggestion
Track whether you registered the load handler and unregister it in cleanup.
Example:
let subscribed = false
if (!map.isStyleLoaded()) {
map.on('load', onMapLoad)
subscribed = true
} else {
onMapLoad()
}
return () => {
if (subscribed) map.off('load', onMapLoad)
if (map.getLayer(layerId)) map.removeLayer(layerId)
if (map.getSource(sourceId)) map.removeSource(sourceId)

There was a problem hiding this comment.
You set the delete marker location to overlay.coordinates[1] and comment it as “Near Top-right”, but the coordinate ordering is documented as [NW, NE, SE, SW], so [1] is exactly NE. That’s fine, but the marker won’t follow when coordinates change unless drawing mode is re-entered because you only create the delete marker inside the drawing-mode effect.
Since that effect depends on overlay.coordinates, it will re-run and recreate the delete marker on every drag (because you update global state on every drag). Combined with the lack of debouncing, this means you’re constantly destroying/recreating the React root and marker during drags.
This is avoidable churn.
Suggestion
Don’t recreate the delete marker/root on every coordinate update.
Option A: Create markers once when entering drawing mode, then update their positions in a separate effect that runs on overlay.coordinates.
Option B: Keep the current effect but move the delete marker position update to a lighter-weight branch:
// when already exists

updateDrawingContext now accepts imageOverlays, but the signature still uses any[] and cameraState: any. While tsc passes, this is an unsafe-but-type-valid boundary: you’re persisting untyped blobs to the DB and later JSON.parse them into runtime structures.
Given this feature’s complexity (Mapbox sources/layers depend on coordinate ordering and URL), it’s worth strongly typing the persisted payload to prevent silent corruption.
Suggestion
Replace any with your shared types (MapData, ImageOverlay, CameraState) for the server action payload and validate minimally before writing.
Example:
import type { CameraState, ImageOverlay } from '@/components/map/map-data-context'
export async function updateDrawingContext(
chatId: string,
contextData: {
drawnFeatures?: MapData['drawnFeatures']
imageOverlays?: ImageOverlay[]
cameraState: CameraState
}

- Around line 1-2: Remove the committed Mapbox token by replacing the real value
for NEXT_PUBLIC_MAPBOX_ACCESS_TOKEN with a placeholder (e.g.
NEXT_PUBLIC_MAPBOX_ACCESS_TOKEN=YOUR_MAPBOX_TOKEN_HERE) or move the current .env
contents into .env.example, add .env to .gitignore so secrets aren’t tracked,
and update deployment/config to load the real token from environment/secret
storage; reference the NEXT_PUBLIC_MAPBOX_ACCESS_TOKEN variable in the repo to
locate and update all usages and rotate the exposed token in your Mapbox
account.
In `@app/search/`[id]/page.tsx:
- Around line 62-71: The parsed JSON assigned to initialMapData (from
latestDataMessage) must be validated to ensure it matches the expected MapData
shape before passing to MapDataProvider; update the parsing block
(latestDataMessage / initialMapData) to: try parsing, then check that the result
is an object and that drawnFeatures, markers, and imageOverlays exist and are
arrays (or coerce to empty arrays as a safe default); on validation failure, log
a clear error and set initialMapData to a safe fallback object ({ drawnFeatures:
[], markers: [], imageOverlays: [] }) so MapDataProvider and downstream
components never receive malformed data.
In `@components/chat.tsx`:
- Around line 92-102: The effect calling updateDrawingContext on every
mapData.imageOverlays change should be debounced or committed only on drag end
to avoid per-drag DB writes; modify the useEffect that references id,
mapData.drawnFeatures, mapData.imageOverlays, and mapData.cameraState to buffer
rapid updates (e.g., use a debounce timer via useRef/useEffect or a
useCallback-wrapped debounce) or replace the frequent trigger with a single
commit on the map dragend event, and ensure updateDrawingContext is only invoked
after the debounce delay or on drag end with the latest
drawnFeatures/imageOverlays/cameraState.
In `@components/map/image-overlay-layer.tsx`:
- Around line 51-83: The useEffect's onMapLoad listener isn't removed on
cleanup, the image layer opacity uses || causing 0 to default to 0.7, and the
React root created for the delete button is never unmounted; fix by (1) storing
onMapLoad and, in the cleanup return, call map.off('load', onMapLoad) if you
previously attached it (or always call map.off to be safe) alongside removing
layer/source in useEffect, (2) change any 'raster-opacity': overlay.opacity ||
0.7 (and the other occurrence) to use nullish coalescing 'raster-opacity':
overlay.opacity ?? 0.7, and (3) keep the createRoot instance (e.g.,
deleteButtonRoot or similar variable used where you call createRoot) in scope
and call its unmount() in the same cleanup; also wrap forEach callbacks in
explicit { } blocks for clarity.
- Around line 62-69: The raster layer's opacity uses a truthy fallback
(overlay.opacity || 0.7) which treats 0 as false and prevents fully transparent
overlays; update both uses (the paint 'raster-opacity' in the map.addLayer call
where layerId is added and the other occurrence around line 98) to use the
nullish coalescing operator (overlay.opacity ?? 0.7) so that explicit 0 is
honored while still defaulting to 0.7 when opacity is undefined or null.
In `@components/map/map-data-context.tsx`:
- Around line 49-50: MapDataProvider currently sets state to initialData
directly which can omit drawnFeatures/markers/imageOverlays; change the
initialization in the MapDataProvider (where mapData and setMapData are created)
to merge initialData with a default MapData object so missing fields fall back
to empty arrays (e.g. create a default like { drawnFeatures: [], markers: [],
imageOverlays: [] } and shallow-merge with initialData), and ensure any later
setters that replace mapData preserve those array defaults when merging updates.
In `@components/user-message.tsx`:
- Around line 82-101: The hover-only reveal for the Place on Map button is not
accessible on touch devices; update the wrapper and button visibility so the
control is reachable via keyboard and touch by adding focus-based styles (e.g.,
include group-focus-within:opacity-100 alongside group-hover:opacity-100 on the
absolute button container), ensure the container is keyboard-focusable (add a
tabindex or use a semantic button wrapper) and confirm handlePlaceOnMap remains
the click/keyboard activation handler on the Button component (refer to the
Button element with onClick={handlePlaceOnMap} and the surrounding div using
classes "group" and "absolute top-4 right-4 ...").
- Around line 28-30: The current hooks (useMap, useMapData, useMapToggle) assume
their contexts always exist which will break if UserMessage is used outside
Chat; change the hooks to be defensive (return null/undefined or safe no-op
functions instead of throwing when their Provider is missing) and update
UserMessage to safely read from them (e.g., const mapCtx = useMap(); const map =
mapCtx?.map; and const setMapDataFn = useMapData()?.setMapData; const
setMapTypeFn = useMapToggle()?.setMapType) and keep the existing guard in the
Place on Map handler that checks for map and imagePart before using them. Ensure
hook return types reflect optional values so callers (UserMessage) can
null-check before invoking methods like setMapData and setMapType.

Validate parsed map data structure before use.
The parsed JSON is passed directly to MapDataProvider without validating that it conforms to the expected MapData shape ({ drawnFeatures, markers, imageOverlays }). Malformed data in the database could cause runtime errors in child components that expect these arrays.
Consider adding schema validation or at minimum structural checks:

Fix Mapbox and React resource leaks in overlay lifecycle.
Three issues cause resource leaks when overlays are added/removed:
- The
map.on('load', onMapLoad)listener (line 76) isn't detached in cleanup, leaving orphaned listeners if the component unmounts before the map style loads. - The React root for the delete button (line 137–138) is never unmounted in cleanup (line 160–163), leaking the React tree.
- Opacity uses
||instead of??(lines 67, 98), so setting opacity to0incorrectly defaults to0.7instead.
Additionally, consider wrapping forEach callbacks in explicit blocks for clarity (lines 107, 161).

All three hooks are currently used safely within the Chat context.
UserMessage is always rendered through components within the Chat component, which is wrapped with MapDataProvider in both entry points (app/page.tsx and app/search/[id]/page.tsx). MapProvider and MapToggleProvider wrap the entire application in the root layout. Therefore, useMap(), useMapData(), and useMapToggle() will not throw errors in current usage.
The "Place on Map" button is only rendered when an image is attached (imagePart exists), and the handler has guard clauses (if (!map || !imagePart) return), so the feature gracefully handles edge cases.
If UserMessage is ever extracted and used outside the Chat component in the future, the hooks would fail. Consider adopting defensive context access if you anticipate broader reusability.

🧹 Nitpick | 🔵 Trivial
Consider touch device accessibility for the hover-revealed button.
The button only becomes visible on hover (opacity-0 group-hover:opacity-100), which works for mouse users but may not be discoverable on touch devices where hover states don't exist.
Consider adding group-focus-within:opacity-100 or making the button always visible (perhaps with reduced prominence):

179-179: The review comment's concern is unfounded. The database schema definesroleas a simplevarchar(50)column with no constraints, enums, or CHECK conditions. The comment on the schema merely lists examples ('user', 'assistant', 'system', 'tool') but does not enforce them. The 'data' role will insert successfully without any constraint violation.

Consider importing from lodash/debounce for smaller bundles.
While modern bundlers tree-shake { debounce } from 'lodash', importing directly from lodash/debounce guarantees only the debounce module is included.

🧹 Nitpick | 🔵 Trivial
Move import to the top of the file.
The @upstash/redis import is placed mid-file after function definitions. While hoisting makes this work, conventional placement at the top improves readability. The @ts-ignore also suppresses potential legitimate type errors.
🔧 Suggested placement
Move the import to the top with other imports (after line 18), and address the underlying type issue rather than suppressing it:
import { getCurrentUserIdOnServer } from '@/lib/auth/get-current-user'
