Design Patterns

Listing Data Model

interface PropertyListing {
  id: string;
  mlsNumber?: string;
  status: ListingStatus;

  // Property Details
  propertyType: PropertyType;
  address: Address;
  coordinates: GeoPoint;

  // Specifications
  bedrooms: number;
  bathrooms: number;
  squareFeet: number;
  lotSize?: number;
  yearBuilt?: number;

  // Pricing
  listPrice: Money;
  priceHistory: PriceChange[];

  // Features
  amenities: string[];
  features: PropertyFeature[];

  // Media
  photos: PropertyPhoto[];
  virtualTourUrl?: string;
  floorPlans: Document[];

  // Metadata
  listedAt: Date;
  updatedAt: Date;
  daysOnMarket: number;
  agent: AgentInfo;
}

Search Architecture

interface PropertySearchService {
  // Full-text and faceted search
  search(query: PropertySearchQuery): Promise<SearchResults>;

  // Geospatial queries
  searchByLocation(center: GeoPoint, radius: number): Promise<PropertyListing[]>;
  searchByPolygon(polygon: GeoPolygon): Promise<PropertyListing[]>;

  // Recommendations
  getSimilarProperties(listingId: string): Promise<PropertyListing[]>;

  // Saved searches
  saveSearch(userId: string, query: PropertySearchQuery): Promise<SavedSearch>;
  executeSavedSearches(): Promise<void>; // For alerts
}
