GeoService in Go

PkgGoDev Build Status codecov Go Report Card

Code Coverage

codecov.io

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,

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.
