I recently noticed that Geofire has been archived on Github: https://github.com/googlearchive/geofire
Fortunately Geofire continues to work but I don't know for how long. Will depending on it harm my work in the future? Are there any other libraries like it?

There are three active Geofire projects:
There is also a top-level Geofire project that was meant to contain things that cross the languages. But it was never updated that top-level project after we created it, so we archived it about half a year ago. The Geofire libraries for the specific languages are still active though.
