A geocoding service developed in Go's way, idiomatic and elegant, not just in golang.
This product is designed to open to any Geocoding service. Based on it,
- Google Maps
- MapQuest
clients are implemented in ~50 LoC each.
It allows you to switch from one service to another by changing only 1 line, or enjoy all the free quota (requests/sec, day, month...) from them at the same time. Just like this.
