Don’t need to write server side programming language for get the data from server side like PHP node. We can directly retrieve the data from client side applications. So no need to knowledge about back-end service.

Setup Firebase Database

Already I told Firebase is JSON based. Every data synchronized from JSON way to communicate with client side application. JSON data stored as well structured format so we can easily get a data from user side.
