Hey HN, I’m the author of GeoFire 2.0. We built GeoFire to provide Firebase users with a client-side solution to querying geolocations in an efficient manner. You can use it to store geolocation data about items (e.g. cars, restaurants, hotel rooms) and then do location-based queries on that data in realtime. The library is built entirely on top of Firebase and has no extra server-side components. And its API will now feel right at home for anyone who is familiar with the API for the Firebase web client. It is backed by a comprehensive test suite and fixes some long-standing bugs in the original implementation. I would love to hear and respond to any feedback or questions you’ve got. And also to see what you create with it!
