Firebase

Is pretty much capable of fulfilling the requirements of “M[model] and C[controller] in MVC” to react Native based applications.

• Supports a real-time NoSQL database for react-native.
• It can be your best bet when it comes to changes like data synchronization and offline data modification.
• Since the idea behind the development of React was to provide a user interface, there was something needed to support and made it fully functional at the backend. This is where firebase as a NoSQL BaaS comes into play.
