Geocoder is a Ruby gem that provides a unified interface for forward and reverse geocoding, IP address lookups, and distance calculations. It integrates with over 40 global geocoding APIs and supports local database lookups via MaxMind and IP2Location. The library offers ActiveRecord and Mongoid model extensions, a command-line interface, and batch processing tasks for efficient geospatial data handling.

How it got here

2009–2011 · Initial release and architectural refactoring

This period covers the initial release of the Geocoder gem, establishing its core API, test infrastructure, and Ruby packaging standards. The codebase underwent significant internal refactoring to improve modularity, introducing a CLI, a block-based configuration DSL, and a unified result interface. It also expanded support for numerous geocoding providers and local database lookups.

2012–2021 · Test coverage and caching architecture

This period focused on significantly expanding test coverage across geocoding providers and core utilities, while introducing a modular cache store system with Redis TTL support. The work also included adding Rails generators for MaxMind GeoLite2 databases and updating CI configurations for Rails 5.0 compatibility.
