Component Architecture

1. LocationMapComponent ✅

Main interactive map component handling:

• Map initialization and rendering using Leaflet.js
• Marker management with layer groups
• Viewport control with zoom/pan
• Event handling for user interactions
• Custom controls for zoom and centering
• Selected location display
• Mobile-responsive layout

Technical Features:

class LocationMapComponent extends Component
{
    public ?float $latitude;
    public ?float $longitude;
    public int $zoom = 13;
    public array $markers = [];
    public ?array $selectedLocation;
    public bool $interactive = true;
    public bool $showControls = true;
}

Event System:

• locationSelected: When a location is chosen
• markerClicked: When a map marker is clicked
• mapMoved: When the viewport changes
• zoomChanged: When zoom level updates

2. LocationSelectorComponent ✅

Location selection interface providing:

• Address search with autocomplete
• Map-based coordinate selection
• Current location detection
• Validation feedback
• Selection confirmation

Technical Features:

class LocationSelectorComponent extends Component
{
    // Search State
    public string $searchQuery = '';
    public array $searchResults = [];
    public bool $isSearching = false;
    public ?string $validationError = null;

    // Location State
    public ?float $latitude = null;
    public ?float $longitude = null;
    public ?string $formattedAddress = null;
    public bool $isValidLocation = false;

    // UI State
    public bool $showSearchResults = false;
    public bool $isLoadingLocation = false;
    public string $mode = 'search'; // search|coordinates|current
}

Event System:

• locationSelected: When a location is confirmed
• searchUpdated: When search query changes
• coordinatesChanged: When coordinates are updated
• validationFailed: When validation fails
• modeChanged: When selection mode changes
• requestCurrentLocation: When requesting browser geolocation

3. LocationDisplayComponent ✅

Multiple location display component with:

• Read-only map view
• Marker clustering
• Info window popups
• Custom marker icons
• Zoom to fit markers

Technical Features:

class LocationDisplayComponent extends Component
{
    // Map Configuration
    public array $markers = [];
    public bool $showClusters = true;
    public int $clusterRadius = 50;
    public int $defaultZoom = 13;
    public ?array $bounds = null;

    // Display Settings
    public bool $showInfoWindow = false;
    public ?array $activeMarker = null;
    public array $customMarkers = [];
    public array $markerCategories = [];

    // State Management
    public bool $isLoading = true;
    public ?string $error = null;
    public array $visibleMarkers = [];
}

Event System:

• markerClicked: When a marker is selected
• clusterClicked: When a cluster is selected
• boundsChanged: When map viewport changes
• markersUpdated: When markers are refreshed
• infoWindowClosed: When info window is closed
