This project is derived from node-geocoder with focus on modern code with esm modules.
Features:
- multiple providers
- similar results for all providers
- modern code based on esm modules and native Promises with async/ await
- Typescript types
- http(s) agent by default for reusing tcp connections
- fetch based http adapter with timeout
- cascade providers and stop on first successful result
- combine search results from multiple providers
- configurable circuit breaker which stops calling geocoder e.g. if request limit is exhausted.
- extensive test-suite with examples for getting started
- GeoJSON, GPX formatters

Works with forward and reverse geocoding.
