How could I query Firebase geo locations without GeoFire in order to return results based on distance between two points?

Question

Firebase just updated their sdk to 3.x and the current version of GeoFire 2.x doesn't work.

What I would like to know is the best way to store geo location values so that I can query firebase so that we only return location with in a defined radius around the user.

Example: user defines that they would like all items that are within 20 miles or less from them.

I wonder if I could store a single value from the latitude and longitude that would allow me to quickly query for this data? Or maybe that isn't the right approach ?

Answer 1

It is not possible using pure firebase without implementing some sort of geohash (it is what geofire does). You could use an externa index stored in elastic search or in redis for example
