Backend
-------
- New endpoint GET /analytics/pois/nearby?lat&lng&radius&limit (public,
no guard). Mirrors the neighborhoods/:district/score shape.
- Prisma $queryRawUnsafe with PostGIS ST_DWithin on POI.location::geography
and ST_Distance for the ordered-by-distance result. Default radius 2km,
max 10km; default limit 30, max 100.
- Response maps POIType enum → frontend POICategory so the existing pill
filter in NeighborhoodPOIMap works out of the box:
SCHOOL/UNIVERSITY → school
HOSPITAL/CLINIC/PHARMACY → hospital
METRO_STATION/BUS_STOP → transit
MALL/MARKET/SUPERMARKET/BANK/ATM → shopping
RESTAURANT/CAFE → restaurant
PARK → park
else → shopping (fallback, still filterable)
- New files: application/queries/get-nearby-pois/{query,handler}.ts +
presentation/dto/get-nearby-pois.dto.ts. Registered in analytics.module.ts.
Frontend
--------
- analytics-api.ts: exports NearbyPOI, NearbyPOIsResponse, NearbyPOICategory
and analyticsApi.getNearbyPOIs(lat, lng, radius?, limit?).
- listing-detail-client.tsx: the "Vị trí trên bản đồ" card no longer
renders <ListingMap> for a single pin — it now renders
<NeighborhoodPOIMap> with the property's coords as center, the nearby
POIs as markers, and the existing category-filter pills. A small
"Tìm thấy N điểm quan tâm trong bán kính 2 km" summary sits below.
- The neighborhood score radar card remains below, untouched.
- The spec fixture + mocks extended for the new analyticsApi dependency.
No schema change, no migration. Phase C of 4.
