Question 1

How to chain geocoders in geo-golang for fallback?

Accepted Answer

Use the chained.Geocoder function with multiple geocoder instances, as shown in the README example. This sequentially tries each provider until one returns a result, useful for reliability and quota management.

Question 2

geo-golang vs direct API calls for Google Maps?

Accepted Answer

geo-golang is better for avoiding vendor lock-in and switching providers easily, but direct API calls offer full access to Google-specific features and might have lower overhead for single-provider projects.

Question 3

Does geo-golang support batch geocoding for multiple addresses?

Accepted Answer

The README doesn't mention batch geocoding; it focuses on single address or coordinate lookups. You'd need to implement batching manually or rely on provider-specific methods outside the unified interface.

Question 4

How does geo-golang handle API rate limits and errors?

Accepted Answer

The library abstracts error handling into a common interface, but developers must manage API keys and quotas per provider, as each service has its own limitations and the library doesn't enforce rate limiting.

Question 5

Can I add a custom geocoding service to geo-golang?

Accepted Answer

Yes, the library is designed to be open to any service. You can implement a new provider by following the existing patterns in the codebase, though it requires understanding the geo.Geocoder interface and writing ~50 lines of code.

Question 6

What's the performance impact of using geo-golang with chained geocoders?

Accepted Answer

Chaining increases latency as it makes sequential API calls until success, but it improves uptime. For high-throughput needs, consider using a single provider or parallel calls if supported.
