GeoFirestore is an open-source library that allows you to store and query a set of keys based on their geographic location. At its heart, GeoFirestore simply stores locations with string keys. Its main benefit, however, is the possibility of retrieving only those keys within a given geographic area - all in realtime.
GeoFirestore uses the Firebase Cloud Firestore for data storage, allowing query results to be updated in realtime as they change. GeoFirestore selectively loads only the data near certain locations, keeping your applications light and responsive, even with extremely large datasets.
To run the following examples locally, clone this entire geofirestore repository
and then simply open each example's respective index.html file in the browser
of your choice.
This is a very basic example which shows you how to read from and write to GeoFirestore
and how to handle the promises returned by the set(), get(), and remove()
methods.
It also shows you how to create a GeoFirestoreQuery and respond to keys moving into,
out of, and within the query.
You can check out a live demo of this example here.
