// Efficient caching strategy for IP geolocation
class GeoIPCache {
constructor() {
this.cache = new Map();
this.TTL = 3600000; // 1 hour
}
async getLocation(ip) {
const cached = this.cache.get(ip);
if (cached && Date.now() - cached.timestamp < this.TTL) {
return cached.data;
}
const fresh = await this.fetchFromAPI(ip);
this.cache.set(ip, {
data: fresh,
timestamp: Date.now()
});
return fresh;
}
}3. Error Handling and Resilience
Robust error handling ensures application stability when geolocation services are unavailable.
Resilience Patterns:
- Circuit breaker pattern: Prevent cascading failures
- Graceful degradation: Provide fallback functionality
- Retry mechanisms: Implement intelligent retry logic
- Monitoring and alerting: Track service health and performance
4. Security-First Implementation
Integrate security considerations from the ground up.
Security Best Practices:
- API key protection: Secure API keys using environment variables
- Rate limiting: Implement client-side rate limiting
- Input validation: Validate IP addresses before processing
- HTTPS enforcement: Always use HTTPS for API communications
