Location Selector Component Implementation

Overview

Implementation of the LocationSelectorComponent for the ThrillWiki location management system. This component will provide address search, coordinate selection, and location validation functionality, integrating with our existing GeocodeService.

Requirements

1. Address Search

• Autocomplete search interface
• Integration with GeocodeService
• Search result display
• Error handling
• Loading states
• Input validation

2. Coordinate Selection

• Map-based point selection
• Direct coordinate input
• Coordinate validation
• Format standardization
• Precision control
• Bounds checking

3. Current Location

• Browser geolocation support
• Permission handling
• Accuracy reporting
• Fallback behavior
• Loading states
• Error handling

4. Validation Feedback

• Address verification
• Coordinate validation
• Visual feedback
• Error messages
• Success states
• Loading indicators

Implementation Plan

1. Component Structure

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
}

2. Features

• Debounced address search
• Real-time validation
