Description

Due to some performance and pricing issues a decision has been made to migrate our database from firebase to mongodb. 1) Remove all the firebase code. 1) All the services that use firebase must be changes and made compatible to mongodb. 2) Re-write test for services that were changed.

All the services must use mongodb instead of firebase.

All the services depends on firebase and its libraries.
