I've tried to check adaptor module, but it seems adaptors for browser and node are hardcoded there. Even if I can inject adaptor into node adaptor, the one from google is still imported there so I'd have to have it installed in my react native project.
React Native Firebase is trying to have the same JS API as browser one
import firestore from '@react-native-firebase/firestore';
// Get user document with an ID of ABC
const userDocument = firestore()
.collection('Users')
.doc('ABC');
