## What it is
GeoFire is a lightweight JavaScript/TypeScript library that stores and queries keys by geographic location on top of the Firebase Realtime Database. It enables realtime geoqueries, returning only keys within a given radius as data changes.

## Use cases
- find nearby users in realtime with firebase
- store and query locations by radius
- build a realtime map of nearby drivers
- geo query keys within a geographic area
- location-based notifications as positions update
- add geolocation queries to a firebase app

## When to choose
- you use Firebase Realtime Database and need realtime location queries
- you want lightweight geo indexing without changing your existing data model
- you need selective loading of only nearby data for large datasets

## When to avoid
- you use Cloud Firestore instead of Realtime Database (use Firestore geoquery solutions)
- you need offline or non-Firebase geospatial storage
- you need advanced geospatial features like polygons or complex spatial indexes
