invertase/react-native-firebase ? reverse-engineered prompt

Build me a React Native Firebase library that gives React Native apps easy access to Firebase features on both iOS and Android.

I want it to feel like the official Firebase web SDK, so developers can use familiar methods in TypeScript and share as much code as possible across mobile and web. Please make it modular, so people can install only the pieces they need, like app setup, auth, analytics, Firestore, messaging, storage, crash reporting, functions, and remote config.

It should be well documented, strongly typed, and backed by tests. Also include clear setup instructions for React Native projects, plus example usage for the main modules. If you need current Firebase or React Native setup details, look up the latest docs online and follow the recommended approach.
