Complete Implementation Guide
- Step 1: API Setup
javascript
// Enable in Google Cloud Console:
// - Maps JavaScript API
// - Geocoding API
// - Places API (optional)
// Secure your API key with restrictions
const API_CONFIG = {
key: 'your_restricted_api_key',
allowed_domains: ['yourdomain.com'],
enabled_apis: ['Maps JavaScript API', 'Geocoding API']
};Code language: JavaScript (javascript)
- Step 2: Full HTML/JavaScript Implementation

Professional business locations map with filtering and clustering

🚀 Advanced Features
Real-time Data Integration
javascript
// Live location updates
function connectToLiveData() {
const eventSource = new EventSource('/api/locations/stream');
eventSource.onmessage = (event) => {
const newLocation = JSON.parse(event.data);
addLocationToMap(newLocation);
};
}
// Batch processing for large datasets
async function processLargeDataset(locations) {
const batchSize = 100;
for (let i = 0; i < locations.length; i += batchSize) {
const batch = locations.slice(i, i + batchSize);
await addLocationsBatch(batch);
// Prevent UI freezing
await new Promise(resolve => setTimeout(resolve, 100));
}
}

Performance Optimization
javascript
// Efficient marker management
class MarkerManager {
constructor(map) {
this.map = map;
this.markers = new Map();
this.clusterer = new markerClusterer.MarkerClusterer({map});
}
addMarker(location) {
const marker = new google.maps.Marker({
position: location.position,
title: location.name
});
this.markers.set(location.id, marker);
this.clusterer.addMarker(marker);
}
removeMarker(locationId) {
const marker = this.markers.get(locationId);
if (marker) {
this.clusterer.removeMarker(marker);
this.markers.delete(locationId);
}
}
}

🛠️ Common Challenges & Solutions
Problem: Address Geocoding Accuracy
javascript
// Enhanced geocoding with validation
async function preciseGeocode(address) {
const geocoder = new google.maps.Geocoder();
try {
const results = await new Promise((resolve, reject) => {
geocoder.geocode({ address }, (results, status) => {
status === 'OK' ? resolve(results) : reject(status);
});
});
// Prefer high-accuracy results
const preciseResult = results.find(result =>
result.geometry.location_type === 'ROOFTOP'
) || results[0];
return {
position: preciseResult.geometry.location,
formattedAddress: preciseResult.formatted_address,
accuracy: preciseResult.geometry.location_type
};
} catch (error) {
console.error('Geocoding failed:', error);
return null;
}
}
