Data Flow

Map.tsx (state owner)
  ├── useQuery(MapQueries.getLocations) → MapService.getLocations()
  ├── MapSearchBar → MapService.suggestPlaces() / searchLocations()
  ├── MapBottomSheet → MapCard[] → handleSetSelectedId()
  ├── MapDetailSheet → MapService.getLocationDetail()
  ├── MapView → kakao.maps.Map + MapMarker[]
  └── StoreCategoryFilter → selectedStoreCategories state

Key State

// Map.tsx
const [center, setCenter] = useState({ lat, lng });     // Map center
const [mapZoom, setMapZoom] = useState(3);               // Zoom level
const [selectedId, setSelectedId] = useState<number | null>(null);
const [selectedStoreCategories, setSelectedStoreCategories] = useState<string[]>([]);
const [searchResults, setSearchResults] = useState<LocationListResponse | null>(null);
const [toggle, setToggle] = useState<ToggleType>('all'); // Source filter

API Types

// LocationListRequest
{ lat, lon, radius?, zoom?, store_category?, pickup_category? }

// LocationListItemResponse
{ id, name, source, road_address?, latitude, longitude, distance_km?,
  distance_text?, store_category?, is_open?, is_holiday?,
  start_time?, end_time?, phone?, pickup_categories?, place_url?, kakao_place_id? }

// SuggestEntry
{ place_name, address, latitude, longitude, place_url? }

// LocationDetailResponse
{ id, name, source, road_address?, lot_address?, latitude?, longitude?,
  store_category, pickup_categories, phone?, place_url?, kakao_place_id?,
  collection_items?, introduction? }

Store Categories

const STORE_CATEGORIES = [
  { key: 'refill_zero', label: '제로웨이스트' },
  { key: 'cafe_bakery', label: '카페/베이커리' },
  { key: 'vegan_dining', label: '비건/식당' },
  { key: 'upcycle_recycle', label: '업사이클/재활용' },
  { key: 'book_workshop', label: '도서관/공방' },
  { key: 'market_mart', label: '마트/시장' },
  { key: 'lodging', label: '숙박' },
  { key: 'public_dropbox', label: '무인 수거함' },
  { key: 'general', label: '기타' },
];

Environment Variables

Kakao Map Integration

• SDK loader: useKakaoLoaderOrigin hook (loads react-kakao-maps-sdk)
• Map component: <Map> from react-kakao-maps-sdk
• Markers: <MapMarker> with custom overlay
• Pan/zoom events: onCenterChanged, onZoomChanged

Common Patterns

Search flow

1. User types in MapSearchBar
2. Debounce (300ms) → MapService.suggestPlaces(q)
3. Show dropdown with SuggestEntry[]
4. User selects → pan map to coordinates + MapService.searchLocations()

Filter flow

1. User opens StoreCategoryFilter
2. Toggle categories → temporary state
3. "결과보기" button → setSelectedStoreCategories()
4. useEffect triggers refetch() with new store_category param

Detail flow

1. User taps MapCard
2. setSelectedId(id) → MapDetailSheet opens
3. MapService.getLocationDetail(id) → show detail

Directions

// Opens Kakao Map directions in new tab
window.open(`https://map.kakao.com/link/to/${name},${lat},${lng}`)

Known Issues

1. Query key caching: MapQueries.getLocations uses static query key — different map positions return cached data
2. Multiple refetch effects: Three useEffect hooks call refetch() with different conditions
3. MapView marker key: Uses array index instead of item ID
4. Silent error handling: MapDetailSheet/MapSearchBar swallow API errors
